We examine the role of delivery of subsidized seeds and fertilizers in the form of agricultural minikits by local governments in three successive farm panels in West Bengal spanning 1982–1995. These programs significantly raised farm value added per acre, accounting for almost two-thirds of the observed growth. The estimates are robust to possible endogeneity of program placement, controls for farm and year effects, other programs of agricultural development, local weather, and price shocks. The effects of the kits delivery program overshadowed the effects of other rural development programs, including the tenancy registration program Operation Barga. (JEL O13, Q12, Q16, Q18)

The Great Lakes Ballast Technology Demonstration Project has investigated the effectiveness of automatic backwash screen filtration of ballast water during its uptake as a means of minimizing the potential for the introduction of nonindigenous species. The Great Lakes Protection Fund; the State of Minnesota, upon the recommendation of the Legislative Commission for Minnesota Resources (LCMR); the LakeCarriers' Association; Northeast-Midwest Institute; Federal agencies and universities have supported this project. Initial testing during the 1997 operating season involved testing onboard the Seaway-sized bulkcarrier MV Algonorth during operations between the Gulf of St. Lawrence and Great Lakes ports. Thistesting provided important information on system design, operations, and filtration biological effectiveness, but the mechanical test results were of limited value as benchmark experiments. During the summer of1998, the modular system was installed on a barge located in the Duluth, Minnesota, harbor to permit more controlled, intensive mechanical and biological testing. The overall design of the shipboard and the bargeballast water filtration test installations are briefly summarized. The barge mechanical test program involved extended testing with 25 micron, 50 micron, and 100 micron filter screens at a nominal 1500 U.S.gpm using an operating profile that approximates normal ship ballast operations. The results of this test program are reported. Lessons learned in the system design, operation, and test program are discussed.

Usual specially designed barges are involved in the off-shore operations that have to be evaluated by several criteria, inclusive of the seakeeping capabilities. The paper includes a comparative seakeeping study of two constructive versions for a large off-shore barge with a length of 189 m, having different breadths 40 m and 50 m. Both constructive versions are on the full cargo 23000 t condition. The seakeeping analyses are done with our own software DYN-OSC, developed by linear potential Lewis’s strip theory. The seakeeping studies are done in oblique irregular waves with a maximum height of 12 m and for the off-shore barge maximum operation speed of 7 knots. The results of this comparative study reveal the differences in the seakeeping operation capabilities for the two off-shore barge constructive versions.

<p>The operation of dust suppressor and dust collector was operating semi-manually by pressing the power button on the local panel during the initial unloading of coal material from the barge or stockpile, where local operators manage several large areas. This research is carried out on the implementation of Automatic Dust Detector for Dust Suppression operational at Paiton Unit 9 power plants with the aim of increasing the efficiency of operator and equipment performance. We use House of Quality (HOQ) as a determinant of the priority scale for technical response to be implemented, namely the addition of an Automatic Dust Detector. The results obtained showed a decrease in the calculation of the dust suppression operating time, i.e. from 5 hour 54 minutes to 5 hour 6 minutes, from 1005,36L/barge to 869,04L/barge for water consumption, and 1L/barge to 0,86L/barge for chemical use. Furthermore, the implementation of the Automatic Dust Detector can significantly increase efficiency at least 15% from operating time difference. </p>

ABSTRACT The tank barge Morris J. Berman grounded on January 7, 1994, spilling at least 750,000 gallons of low API fuel oil onto the most heavily used beaches of San Juan, Puerto Rico, at the height of tourist season. The vessel's condition deteriorated rapidly due to heavy ocean swells. Most of the discharged oil was blown directly ashore into three natural containment basins. The rest beached in varying quantities along 65 kilometers of shoreline on the north coast from Loiza to Punta Borinquen. On January 8, lightering and salvage operations commenced, the barge was removed from strand on January 15, towed offshore, and scuttled approximately 28 kilometers north of San Juan in 1,000 fathoms of water. Response operations were complicated by the large quantities of oil that sank while retaining its original viscosity and remaining highly mobile. This required a technically, logistically, and financially demanding cleanup operation involving diving, dredging, sand removal, sand washing, sand replacement, and biodegradation.

Abstract Autonomous and unmanned shipping is revolutionizing the maritime industry by introducing a paradigm shift on how to design the vessels and supporting land-side infrastructure. Currently, there is a lack of formalisms on how to plan for such operations, determining the varying degrees of autonomy and human responsibility, whilst ensuring safety and security. This paper describes fundamental concepts of autonomy in the context of ships. These are then applied in a methodology used to create systematic and structured descriptions for the operation of autonomous ship systems. The examples we use are based on ongoing efforts related to a planned autonomous inland waterway (IWW) barge operation. Finally, we show how the descriptions can be used in conjunction with existing safety and security analysis techniques. Our experience with this methodology is that it allows for a smooth transition from the autonomous ship system design phase to the assessment of the same system using UML notations. We believe that the same methodology can be easily applied to the other use cases and similar systems elsewhere.

Installing a large deck onto a platform, such as a spar, using the floatover method is gaining popularity. This is because the operational cost is much lower than other methods of installation, such as modular lifts or a single piece installation by a heavy lift barge. Deck integration can be performed on land, at quay side and will not depend on a heavy lift barge. A new concept for a floatover vessel has been developed for operations in the Gulf of Mexico and West Africa. In this application sea state conditions are essential factors that must be considered in the Gulf of Mexico, especially for transportation. In West Africa, swell conditions will govern floatover deck (FOD) installation. Based on these two different environmental conditions, Technip Offshore, Inc. developed the FOD installation concept using semi-submersible barge type vessels. A significant amount of development work and model testing has been done on this method in recent years on spar floatover. These tests have validated our numerical methods. Another test was conducted to investigate the feasibility of a deck float-over operation onto a compliant tower for a West Africa project. The project consists of a compliant tower supporting a 25,401metricton(28,000s.ton) integrated deck. This paper will describe comparisons between model test data and numerical predictions of the compliant tower floatover operation.

During the past decade intermodal barge transport has been very successful in gaining market share in northwest Europe. The barge sector has been able to cater very well to the ever–increasing demands of shippers. It is now a leading mode of transport along the major river corridors and is opening new geographical markets. These successful developments are due to the beneficial cost–quality features of intermodal barge transport compared with its main competitor, unimodal road transport. However, to remain competitive in existing markets and to expand into new market areas the cost–quality features of intermodal barge transport must be improved. Network operations are important influences on the cost–quality performance. Which barge network operations provide the best performance, however, depends on the transport market to be served. This relation between barge network design, transport market, and the performance of intermodal barge transport is the central issue discussed. A general framework for barge network design is presented describing the design variables for barge networks and showing their relationship to the performance indicators of intermodal barge transport. Given the quantitative relations between the design variables for barge networks, it is possible to assess the performance of different types of barge networks for different transport markets. This tool is empirically demonstrated in a case study on the Rhine River. It demonstrates that changing the network operations will lead to further improvement of the competitiveness of intermodal barge transport in this corridor.

ABSTRACT The extreme diversity of affected shoreline areas in Prince William Sound necessitated a variety of treatment techniques. Innovation produced equipment that was versatile and effective in the environment encountered. This paper reviews some of the key shoreline treatment equipment used during the summer of 1989: the cold water landing craft vessel (LCV), the maxi-barge, the omni-barge, and the hot water LCV. Also addressed are the containment and collection methods used to support this treatment equipment. The paper concludes with a description of the treatment equipment and techniques used to respond to the shoreline conditions encountered in 1990, the second year of the cleanup. The paper stresses the need for flexibility and innovation in cleanup techniques.

Operation of ships with special functions such as dredgers or commonly called Dredger Barge requires special support such as spuds. In addition to being able to replace anchors more effectively, it can also facilitate supporting vessels such as Anchor Handling Tug and ensure safety while operating. In this study planning and analysis needs to be done in order to estimate the reaction and the condition of the spud and the spud holder at the time of operation. The study approach uses Solidwork software to simulate the strength test of the material as well as the safety of the spud and the spud holder when receiving sea wave pressure, ocean currents and wind in extreme weather using Mild Steel (ASTM (S) A36) material. The results of the simulation of the strength and feasibility test of the spud and the spud holder were obtained with a von mises spud value of 0.0856 N / mm2 and a von mises value on the spud holder of 15.5 N/mm2 with the parameter value of the von mises spud and spud holder of 188 N / mm2. Furthermore, the simulation results of the shear stress value on the spud are 2.37x10-7 N/mm2 and the shear stress value on the spud holder is 3.32x10-5 N/mm2 with the parameter value of the spear shear stress and the spud holder of 141 N/mm2. Furthermore, the simulation results of the Deflection value for the spud is 0.00116 mm and the deflection value for the spud holder is 0.117 mm with the deflection spud parameter value of 80 mm, and the deflection parameter for the spud holder is 10 mm. The spud and spud holders in this design are feasible in production and have been guaranteed safety and feasibility by referring to the parameters according to the standards of the Bureau Veritas and American Institute of Steel Construction rules

ABSTRACT In the early morning hours of August 10, 1993, the 14,000 gross ton tank barge Ocean 255, loaded with over 200,000 barrels of aviation fuel, premium and regular gasolines, and diesel fuel collided with the M/V Balsa 37 west of the Sunshine Skyway Bridge in Tampa Bay, Florida. The energy of the collision resulted in an explosion and fire that completely enveloped the 546 foot barge. The fire burned intensely for over 18 hours while the barge lay grounded north of the main ship channel leading into the Port of Tampa. After the fire was extinguished, the transfer of the remaining cargo, to remove the very prominent threat from explosion and pollution, fell to the U.S. Coast Guard's National Strike Force. The Ocean 255's cargo containment, transfer, venting, and safety systems were completely destroyed, and its stability and hull integrity were in question. The operation was faced with uncertain weather including the possibility of a hurricane developing, frequent strong afternoon thunderstorms and squalls, strong currents, and a vessel that was a virtual time bomb. The entire amount of remaining cargo was transferred in eight days of around-the-clock pumping operations. The damage assessment after the explosion complicated the plans for lightering and salvage operations. However, action and site safety plans, and the formation of integrated teams developed by Maritrans LP (owners of the barge and the responsible party) and the National Strike Force, resulted in a successful and safe removal of the remaining 180,000 barrels of highly flammable cargo without further pollution of the waters of Tampa Bay and the State of Florida.

This paper aims to analyze the impact of drought on the life cycle of barge transportation. The LCA method was used to quantify the environmental impact of barge transportation services on the Madeira River/Brazil: Transportation Operation, Barge Fleet, and Waterway Infrastructure. A model for barge convoy formation was developed as a function of river water level variation. From this, the transport operation was simulated, considering the loading of grains from the Madeira River in 2021, as well as the respective fuel consumption and CO2Eq emissions. The results indicate that barge transportation is more harmful to the environment during drought, since only a convoy of nine barges is allowed to navigate, and its energy efficiency is compromised due to the longer travel time and lower loading capacity in one trip. The intense use of this barge convoy implied an increase of 22.25% in CO2Eqemissions when compared to the full river. Doi: 10.28991/CEJ-2022-08-12-02 Full Text: PDF

Abstract Installation and decommissioning activities of offshore structures often applied a floating crane barge for a lifting operation. The excessive movement response of lifted module affected by the motion of floating crane barge in waves can increase a large amplitude. However, the coupled motions of a floating crane barge and lifted module are not easy to predict accurately due to the dynamic movement of a lifted module and the complex coupling system. The coupled motion responses of a floating crane barge and a lifted module during lifting operation were investigated based on time domain by experimental method in this study. The model tests are carried out at Manoeuvring and Ocean Basin of Indonesian Hydrodynamic Laboratory, BRIN. The experimental conditions include the load cases of without and with a load of lifted module in crane tip, and the lifting operation was evaluated under irregular wave conditions. The experimental results show in that the phenomena of shift resonant frequency for the dynamic responses are clearly observed on the coupled motion of multibody system. The dynamic oscillations of the lifted module have a significant effect on the motion response of the floating crane barge. And the hoisting of lifted module has an obstructed effect on the rolling motion of crane barge.

In the ocean fuel transportation industry, the optimization of bunkering operations depends on price, position, delays from the expected route, and the cost of delays caused by the bunker operations themselves. Despite their potential importance, detailed bunker activity statistics at each port of call (e.g: waiting time, barge capacity, berth, or berth) are not available. A greater hid deviation from the usual method is that the provider, therefore, arrives past due for a bunker mission. The purchaser commonly has a time slot wherein it anchors as much as acquire bunker. If the bunker barge arrives past due, the purchaser can be beneath neath time strain because of closing dates for shipment, which may also reason the purchaser to interrupt the bunker operation earlier than the agreed quantity of bunker is supplied. This is obtainable confined interest from transport businesses and charterers because the fraudulent quantity is thought to be negligible. However, studies have recommended that the aggregated quantity of misplaced bunker is of big value. To screen such conduct we intend to make use of Automatic Identification System (AIS) statistics from bunker barges and numerous vessels they supply.

Currently, great attention is paid to the development issue of the shelf’s fuel and energy resources foremost in the oil-gas fields of the Caspian Sea. The problem solution requires the studying of great majority of scientific-technical issues. One of the significant problems is the lead-out of steel jacket from the offshore platform as a major element of oil-gas field hydro-technical facilities meant for the operation in the deep water. The calculations for the execution of operations with steel jacket of deep stationary platform from the block with the detailed chara- cteristics by the mass and gravity center coordinates alongside line data have been carried out with “SACS” and “STAAD.PRO” software programs. The steel jacket is pushed astern with the push-pull equipment on the barge. Due to the shift of gravity centre the jacket changes the trim in the stern. Through the elevation of trim angle brought in alignment with the friction ration between the jacket and barge, the jacket slides further itself. Herewith, the trim increases until the gravity centre of steel jacket on the barge is not in alignment with rotation centre of the large rocker arms. The studies helped to fix the position of the jacket’s gravity centre from the aft perpendicular, the trim moment, the trim of the barge, the draft with the bow and stern and the trim angle as well.

Improvement in river transport requires adopting more efficient towboat propellers. This paper summarizes the design and towboat trials of a new semi-Kaplan propeller with an unconventional pitch distribution. A comparison of towboat trip records shows that operation with semi-Kaplan propellers resulted in improvements over operations with conventionally designed propellers. These improvements included a 13.5 percent increase in barge mpg of fuel and a 10 percent increase in tow speed. The trials with the semi-Kaplan propeller indicated only a small increase in towboat vibration levels. The adoption of this new propeller has potential for improving present river transport.

The paper presents outcomes of the discrete event simulation of the ballast water management in a multi-terminal port. The simulation includes ship’s manoeuvring, cargo and ballast operations and a barge-based ballast water treatment system operating within all terminal areas. The barge-based ballast water treatment system is used by ships unable to use their own equipment, not equipped with an appropriate ballast treatment system or non-compliant with the Ballast Water Management (BWM) Convention 2004 for whatever reason. The main goal is to estimate the productivity and cost effectiveness of such systems as an option to support ships not able to comply with the BWM Convention, once it enters into force. The model was built and tested in Arena simulation software. Process parameters are based on real traffic data for the port of Rijeka. The results indicate that barge-based ballast treatment facility will be heavily underutilized, and that such systems are cost-effective only in ports where large volumes of ballast water need to be delivered to shore treatment systems.

Abstract Changes in the position of the lifting load on the crane barge during heavy lifting operation significantly affect the stability of the vessel. The changes in stability during this heavy lifting operation must be analysed to prevent operational failures. This study conducted an intact stability analysis of the crane barge during lifting of topside structures in the installation phase. The analysis was performed with variations in the position of the lifted load from starboard to bow for every 15° change in the crane angle. The stability results of the Crane Barge for all variations, using both analytical and numerical methods, have met the IMO requirements. The extreme condition occurred in load case 8, with a maximum GZ value of 2.904 m at a 22° angle and an area of 103,894 m.deg. The comparison of the stability results of the crane barge during the structural lifting operation using analytical calculation and numerical methods indicates that the overall validation error values have met the ±5% requirement according to the ABS Rules. However, when considering the corrections for changes in the lifting load moment in the analytical calculation, stability error values increase significantly as the heeling angle of the vessel increases.

The problems of modeling the operation of classic (constant configuration) and variable vessel combination of barges by matrix routing methods are discussed in the paper. Regrouping the combination directly on the route allows you to operate a larger number of barges compared to a permanent combination, which increases its load capacity. The efficiency of water transport is determined by the volume of cargo delivered in relation to operating costs, which depend on the time the vessel is on the route. Additional stops during the voyage of the vessels combination for its reformation allow to increase the total cargo turnover, but lead to an increase in the voyage time, which is a certain contradiction, the solution of which is possible through the use of a variable approach to organizing the work of barge-tug combinations. The results of the mathematical apparatus development for describing the model of the barge-tug combinations movement on inland waterways are presented; the influence of turns on the change in the combinations speed and on the total voyage time is taken into account, and a particular task of regrouping the combination is additionally considered. The route from the Nizhnesvirsky lock to Ladoga Lake, on which turning points and places, where it is necessary to change the barge-tug combinations configuration to pass it are identified, is analyzed. For the mathematical description of the vessel movement along the route, a system of calculation matrices, which allows us to generalize the change and relationship of the speed and time parameters of the vessel movement with its route, including taking into account the time of regrouping the combination, is proposed. The main factors influencing the effectiveness of the combinations operation organization with their reorganization along the route are identified. As a basis for constructing matrices, it is proposed to use turning points, the system of which is formed in the form of a three-level model. The complex of matrices allows to obtain a quantitative presentation of the vessel movement and voyage time, while providing detailed parameters for the combination passage along the individual sections of the waterway, which in general is the basis of the developed information technology for intelligent control of the barge-tug combinations operation.

Reservoir operation plays an important role in the economic development of a region. The storage reservoirs are not only useful for supplying water for municipal and irrigation purpose, but also act as a protection barrier form flood, and the stored water can be used for generation of electricity power as well. To meet the objectives for which the reservoir was planned, it is vital to formulate guidelines for the operation of reservoir. This can be achieved by systematic operation of the system, and by the use of systematic and simplified rule curve for the operation of reservoir. Hedging rules are popular in drinking and irrigation water supply. Application of hedging is now gaining focus for hydropower power reservoir operation. In the present study, attempt has been made to formulate a new operating rule for multipurpose reservoir using hedging rules and the developed model was applied to a case study of Bargi reservoir in the Narmada basin in India. In order to increase the reliability of water supply for municipal, irrigation and average annual power production, the new operating rule has been developed using Standard Operation Policy (SOP) and hedging rule according to the priority of release for different purposes. The hedging rule based simulation model satisfies 97.5% of municipal water supply which is more than 8.25% of the present operational policy. The spill of the reservoir is decreased by 57 % compared to present policy. The performances of different hedging rules were compared with that of a new standard operating policies and the superiority of the hedging rules are discussed in this paper.

The shipbuilding design rules require several criteria for the assessment of any floating structure. For this technical paper, a 23000 t off-shore barge is assessed by oblique waves global strength criteria. Two barge concepts are evaluated, with the main changes of breadth and draught. Focusing on the preliminary analysis that involves the initial concepts of the off-shore barge, the oblique global strength assessment is done by equiva-lent 1D beam structural model approach on significant design waves range. The study of the two off-shore barge concept versions points out their restrictions in operation by global strength preliminary criteria.

In this paper the hydroelastic study is developed for a 23000T off-shore barge, with a maximum length of 189 m, focusing on a comparative study for two design versions with 40 m and 50 m breadth. The initial off-shore barge with 40 m breadth has been extended to 50 m breadth by adding a supplementary tank section at the centerline, so making it possible to ensure transport capabilities for cargo structures extra wide. The two versions of the off-shore barges are analyzed at full cargo capacity of 23000 t case, for speed values 0 and 7 knots, corresponding to operation on-site at zero speed and maximum transition speed conditions, under head irregular waves with interference components, for a short-term averaged waves’ spectrum. The hull structure of the off-shore barge versions is almost uniform over the whole length, mainly being recorded stress hot-spot at the hull transversal bulkheads connection with the other orthogonal panels and forepeak of the barge, with a maximum of 1.2 hot-spot factor at the prismatic barge hull part. This study is developed by own software DYN-HYD, involving the modules for the hydroelastic long-term approach, applied for the evaluation of the safety limit in the long-term operation conditions.

Barge ships are designed to transport and assemble heavy and massive pieces of equipment at sea. Active propulsion systems are not installed in this type of ship, so the desirable motion and positioning of these ships can only be achieved with the assistance of several tugboats. In this study, the dynamical characteristics of barge conveying systems were formulated and robust control systems were designed to ensure efficient barge operation. To achieve these objectives, we first developed a mathematical model of a barge ship, which incorporated a novel conveying system configuration using tugboats. We then designed a robust controller for the tugboats that used the sliding mode law to deliver the desired barge motion performance. Finally, the usefulness of the proposed configuration and controller was verified via simulation studies using another system with an H∞ controller. The proposed sliding mode controller showed superiority, especially in terms of robustness against disturbances.

Abstract: In December 2015, operations were successfully completed in the recovery of a highly toxic cargo from the sunken tank barge ARGO in Lake Erie. The ARGO, constructed in 1911, sank in 1937 with a cargo of benzol that contained a high percentage of the carcinogen benzene. The ARGO was previously listed as the highest environmental risk in the Great Lakes by the National Oceanic and Atmospheric Administration’s Remediation of Underwater Legacy Environmental Threats (RULET) study. To recover the cargo, salvors designed a diver directed hot-tapping and pumping system to pump the remaining high benzene cargo from the sunken barge at a depth of approximately 50-feet below the lake’s surface. The cargo off-load system included pumping the cargo to a series of storage tanks onboard a barge equipped with designed-for-purpose inert gas and vapor recovery systems to ensure the safety of the public and responders. Working in a Unified Command that included the Coast Guard, U.S. and Ohio Environmental Protection Agencies and National Oceanic Atmospheric Administration, the salvage crew achieved all operational objectives – from safely conducting around-the-clock cold-water contaminated water diving operations to collecting environmental and barge hull samples for further analysis. The ARGO case study will provide lessons learned to assist future responders in safely performing subsea oil removal operations. Additionally, the case study will frame the discussion of current submerged oil recovery regulations and guidance, including the 2016 American Petroleum Institute (API) sunken oil detection and recovery guidance and the U.S. Coast Guard’s guidance on the classification of Oil Spill Removal Organizations (OSRO) that perform non-floating oil detection and recovery operations.

Pipeline end termination (PLET) installation is an essential part of offshore pipe-laying operation. Pipe-laying operations are sensitive to pipe-laying barge motion and marine environmental conditions. Monitoring the field environment can provide a reasonable basis for planning pipe-laying. Therefore, the measurement and analysis of sea wave motion is helpful for the control and operational safety of the pipeline and vessels. In this study, an environmental monitoring system was established to measure wave motion during PLET operation. Fourier transforms were used to process images that were acquired by ultra-high-frequency X-band marine radar to extract wave parameters. The resulting wave spectra, as measured each minute, were used to simulate real-time wave data and calculate wave characteristics and regressed wave frequency and direction spectrum throughout the PLET operation. The regressed frequency, spectral density, and direction spectra were compared with the theoretical spectra to evaluate their similarity and find the most similar spreading function in the operational area (the South China Sea). Gaussian fitting of real-time wave data was tested while using a classical method. The marginal distribution and joint density of the wave characteristics were estimated and then compared with theoretical distributions to find the most suitable model for improving marine environmental forecasting.

In the study case area, Untung Jawa-Tanjung Pasir sea, the most appropriate cable laying platform is a barge. A barge is not equipped with the propulsion system and considering the cable laying operation requirement, barge given condition, environmental disturbances, the barge must be equipped with portable dynamic positioning thruster. An azimuth thruster is the proposed way to overcome this problem. The research done shall determine the barge’s necessary engine and propeller to fulfil its need. Using ship manoeuvring equation, the required thrust of the barge for surge, sway, and yaw are 274.36 kN, 289.21 kN, 3292.67 kNm respectively. To produce the required forces and moment, the researcher utilizes Cummins KTA38 (634 kW) diesel engine, Masson Marine gearbox (5.542:1), and Ka4-70 Nozzle 24 with the diameter of 1.6 m and P/D value of 1.06. In the free running condition, the barge will run with the speed of 3.52 m/s or 6.85 knots.

A nine-degree-of-freedom time domain mathematical model was used to numerically simulate crane ship dynamics. This model considers the elasticity and damping of the hoisting rope assembly and includes arbitrary, biangular swing of the suspended hook load coupled with surge, sway, heave, roll, pitch, and yaw motions of the hull. The linear frequency-dependent hydrodynamic response to the hull’s own motions accounted for memory effects that were approximated in the time domain by a finite state space model. The nonlinear hydrodynamic drag force acting on the oscillating hull was quadratically approximated using an empirical drag coefficient. The incident wave force on the hull consisted of the first-order force oscillating at wave frequency and the second-order slowly varying wave drift force. The nonlinear horizontal mooring system restoring force was approximated by a third-order polynomial. To specify operating limits for a shear-leg crane barge in a heavy lift offshore operation, a stochastic analysis was performed based on the system’s simulated dynamic response in an ensemble of natural seaways.

ABSTRACT A major spill of 692,000 gallons of catalytic feedstock oil resulted when the Greek tankship Shinoussa collided with and sank the tank barge Apex 3417 and damaged the tank barge Apex 3503 in the Houston Ship Channel, Galveston Bay, Texas on July 28, 1990. The owner of the barges took immediate action to contain and recover the oil and salvage the sunken barge, but on the sixth day withdrew from the cleanup. The Coast Guard On-Scene Coordinator (OSC) federalized the cleanup and continued for another 15 days, completing the cleanup on August 17, 1990. Bioremediation microbes were used for the first time by the OSC to treat oiled marsh areas. Visually, the treatment appeared successful. Several problems were encountered and lessons learned during the major cleanup operation.

ABSTRACT Buffalo 292 was a 275-foot bunker barge loaded with 17,000 barrels of IFO 380. On March 18, 1996, Buffalo 292 was heading southbound along the Houston Ship Channel. High winds, rough seas, and the barge's loading condition caused the barge to buckle and spill 3000 barrels of product into Galveston Bay. Operational success was linked to the training and experience of the responding agencies, local government assistance, rapid assessment team operations, and the dedicated efforts of the planning section. Responding agencies demonstrated that a unified response is the only way to cope with an environmental disaster of this magnitude.

ABSTRACT In the late summer of 1995, the U.S. Coast Guard supervised the successful removal of over 340,000 gallons of no. 6 oil from the sunken wreck of the tank barge Cleveco on the bottom of Lake Erie near Cleveland, Ohio. Many challenges were faced in trying to determine the amount of oil in a barge that had sunk 50 years before and was lying upside down and nearly completely buried in 70 feet of water. The salvage contractor and the U.S. Coast Guard overcame many technical problems in developing an effective and low-risk method of oil removal. The solution included the use of a hot-tap drill and phased pumping system to maximize the amount of oil recovered. The underwater operation required many divers and a total force of 55 personnel working together for the 33-day duration. This was the largest operation of its kind in the Great Lakes and offers valuable lessons to others who may encounter similar situations.

The paper discusses the process design and mass balance for the minimum and maximum design case to illustrate the ISO 8685 compliance of a 2-year-running barge loading payment station sampling plant. The plant samples -100 mm, export quality, bauxite material from a barge-loading conveyor delivering 10 kton/h at 5.4 m/s. The green field operation does not know the Coefficient of Variation or the Size Range Factor as required inputs to calculate the Number of Primary Increments and Minimum Gross Sample Mass required. Therefore, informed assumptions were made given performance data of a neighboring sampling system that is in operation for over a decade. Without the available variation and size factor data the ISO-compliant scheme design could not commence. Where this data is not available for green field projects, it poses a risk that plant designs may not be compliant where variabilities could exceed assumptions on the input parameters. The system is designed for various barge carrying capacities with lot size in mass. Operational quality assurance however requires samples more frequently and therefore sublot periods are 4 hourly time based. ISO 8685 compliance is achieved with sample increments taken at maximum throughputs and barge sizes to determine the time-based interval. At reduced throughputs, the fixed time interval regime results in the minimum ISO requirements to be exceeded and tied in well with client overall quality incentives. Primary sample increments from a tailored cross belt sampler are crushed automatically in the sampling plant to 25 mm and then to 6mm using two stages of double roll crushers. The sample is then subdivided through secondary and tertiary sampling to produce a composite 4-hourly chemical sample. The 4-hourly sublot samples are collected in an ergonomic 4-way carousel with each composite sample representing 1-hour barge loading production— allowing the client quality assurance insights into their blending facility performance.

The studies on floating offshore wind turbines (FOWTs) have been increasing over recent decades due to the growing interest in offshore renewable energy. The present paper proposes a barge platform with four moonpools to support the Technical University of Denmark 10 MW wind turbine for a designed water depth of 60 m. A 4 × 2 mooring system with eight mooring lines is also proposed for the barge platform. The main dimensions of the barge platform are optimally selected with respect to its preliminary hydrodynamic properties and potential financial benefit. The proposed barge-type FOWT is then demonstrated to be aligned with the DNV standard requirements in terms of its intact and damage stability. Furthermore, coupled time-domain simulations are conducted for the proposed barge FOWT with mooring under the selected environmental and operational conditions by using Simo-Riflex-AeroDyn (SRA). Through decay test simulations, the natural periods of the barge-type FOWT are demonstrated to be within the DNV recommended ranges. The proposed mooring system is also benchmarked with the 3 × 3 mooring concept that was used for a 3 MW barge-type FOWT installed in Kitakyushu. The response magnitudes of the barge platform and mooring line tension are similar to both mooring systems, and thus the 4 × 2 mooring system is preferred due to its lower cost. In addition, the proposed barge platform is preliminarily demonstrated to be able to survive for the 50-year extreme environmental conditions under parked wind turbine status, as well as the normal environmental conditions under the operating status.

Abstract The paper presents an innovative steering system for a river push barge dedicated for operation in environmentally sensitive inland waterways. Development of the inland waterborne transport in Poland is dependent on the exploitation of rivers which can be adapted to navigation in the limited range because a high percent of their length is classified within special environment protection areas of Natura 2000 network. This is now the main reason that their better exploitation cannot be obtained without an introduction of a new generation of waterborne environment friendly inland units. In naturally winding rivers with differing and rapidly changing depths and widths it is important to equip a push barge with an efficient steering system that has a low environmental impact. The innovative steering system proposed in the paper is composed of main steering devices located at the pusher stern, auxiliary steering devices installed on the barge bow and a mechanical coupling system.

Abstract The district of Belakang Padang consists of 108 islands. On these islands, 43 islands are inhabited and 65 islands are uninhabited. The source of pollution on this island comes from community activities on land, such as throwing garbage in the sea and so on. In this paper, Floating Waste Treatment Facility will be designed on Self-Propelled Barge (SPB) with principle dimension: Lpp = 13 m; B = 2.48 m; and T = 0.589 m. The barge can accommodate 7 tons of waste consisting of a garbage tank and a sorting process along with a plastic press machine to reduce the volume of plastic waste. In the calculation of the volume requirement for waste weighing 7 tons, that is 16.43 m3. With an estimated 9 hours of sorting work, it can meet the volume of waste needs. The total investment for the construction of this facility is Rp 362,087,076.12 and the annual operating costs are Rp 458,692,802.67. This facility is feasible to build because of the value of several economic metrics as follows: NPV Rp 488,234,793; IRR 26% and PI 2,348.
