Underwater explosion vessel is the main equipment to experimentally study the law of underwater explosion by small quantity of explosive. It is the main equipment of explosive metalworking. In order to the safe using of underwater explosion container and the efficiency, we must accurately determine the strength of the container. Based on the actual engineering design, the brief summary about engineering design method of 10gTNT equivalent deep water explosion vessel has carried on.

<p>Tethered underwater robot (TUR) for underwater vessel anchor release is presented. In off-shore oil and gas enviromnment, there has been series of reported cases on stuck vessel anchors after mooring operations and divers are sent to release these anchors for the vessels to be in motion. The use of divers to perform such function is very risky because of human limitation and some divers have been reported dead on the process due to high pressure underwater or being attacked by underwater wide animals. This has caused very serious panic to the vessel owners and hence, this work is aimed to develop TUR that would be used by the vessel operators instead of divers to release the stuck anchor without loss. The underwater robot system comprises of three basic sections namely graphical user control interface (GUCI) that would be installed in the operator’s laptop, the WiFi LAN router for network connection, and TUR system hardware and software. Each of these sections was strictly designed. Various high-level programming languages were employed to design the GUCI and code the interface buttons, robot controller program codes etc. The implementation carried out and the prototype system tested in the University of Port Harcourt’s swimming pool of 6m depth for validation. The robot performed extremely good in swimming and release of constructed anchor underwater.</p>

This paper describes the preliminary process for designing a 250 ft dynamically positioned, Diving Support Vessel. This is to serve the offshore oil industry as a platform for underwater intervention. Enlisting the use of the latest technological advances, the vessel will support both remotely operated vehicles and human divers. We will trace the development of this design with a well-defined agenda. Beginning with an analysis of the existing fleet, a practical hull form is created, which leads to solid estimations for hydrostatics, stability, resistance, powering and preliminary arrangements. We will also discuss the steps that will follow over the next several months.

Measurements of the source levels of 9880 passes of 3188 different large commercial ships from the Enhancing Cetacean Habitat and Observation (ECHO) program database were used to investigate the dependencies of vessel underwater noise emissions on several vessel design parameters and operating conditions. Trends in the dataset were analyzed using functional regression analysis, which is an extension of standard regression analysis and represents a response variable (decidecade band source level) as a continuous function of a predictor variable (frequency). The statistical model was applied to source level data for six vessel categories: cruise ships, container ships, bulk carriers, tankers, tugs, and vehicle carriers. Depending on the frequency band and category, the functional regression model explained approximately 25%–50% of the variance in the ECHO dataset. The two main operational parameters, speed through water and actual draft, were the predictors most strongly correlated with source levels in all of the vessel categories. Vessel size (represented via length overall) was the design parameter with the strongest correlation to underwater radiated noise for three categories of vessels (bulkers, containers, and tankers). Other design parameters that were investigated (engine revolutions per minute, engine power, design speed, and vessel age) had weaker but nonetheless significant correlations with source levels.
