Abstract (sommario):

The wheat stripe rust pathogen (Puccinia striiformis f. sp. tritici; Pst) was first detected in Australia in 1979. The features of the initial pathotype suggested that it was of European origin, and later work provided evidence that it was most likely transmitted as adherent spores on travellers’ clothing. Despite long-held views that this cool temperature pathogen would not adapt to Australian conditions, Pst became endemic and progressively adapted to commercial wheat production through step-wise mutation. Several of these mutant pathotypes became frequent in the Pst population, causing widespread infection and significant costs to production (yield and quality losses; chemical control expenditure) in certain cultivars and seasons. Pathotype evolution, including adaptation to native barley grass (Hordeum spp.) populations, is described. The occurrence of an exotic pathotype of Pst in Western Australia in 2002, and its subsequent spread to eastern Australia, represented a major shift in the pathogen population. This pathotype dominated pathogen populations throughout Australia from 2003, with chemical control expenditure estimated at AU$40–90 million annually. Another exotic introduction was detected in 1998. Initial data indicated that certain isolates collected from barley grass were highly avirulent to wheat differentials, with the exception of partial virulence to Chinese 166. Further seedling tests revealed that these isolates, tentatively designated barley grass stripe rust (BGYR), were virulent on several Australian barleys, notably those of Skiff parentage. Data, including molecular studies, suggest that BGYR is a new forma specialis of P. striiformis. Field nurseries indicate that BGYR is likely to have little impact on commercial barley, although this may change with further pathotype evolution or the release of susceptible cultivars.

Abstract (sommario):

Heading date is a major determinant of the regional and seasonal adaptation of barley varieties. The dogma is that introduced germplasm is more likely to be adapted if it is derived from a similar latitude. However, barley germplasm introduced from similar latitudes of South-East Asia is extremely early heading in the Australian environments and vice versa. A doubled-haploid population from a cross of an Australian barley Galleon and a Japanese barley Haruna Nijo was evaluated for heading date in Australia (Perth, 31°56′S) and China (Wuhan, 30°33′N) under normal autumn sowing, late sowing in the field, and extended-light glasshouse conditions. One major QTL was identified on chromosome 5H under the three conditions in China. The single QTL accounted for up to 50% of phenotypic variation for heading date. The Australian variety contributed to late heading date. Two QTLs on chromosomes 4H and 5H were detected for controlling heading date in Australia. The QTL/QTL interaction contributed up to 35.8% of phenotypic variation for heading date in Australia, which is the major reason for the extremely early heading date of the Japanese variety in the Australian environment. The chromosome 5H QTL was detected at the same chromosomal location when the population was grown in either China or Australia. In both environments the Australian variety contributed to the late heading date. Selection against the Japanese alleles of chromosomes 4H and 5H QTLs could eliminate the extremely early genotype in Australia and selection against the Australian allele of chromosome 5H QTL could eliminate the extremely late genotype in China when Australian and Japanese germplasms are used in the breeding programs.

Abstract (sommario):

Net type net blotch (NTNB) is a prevalent disease in Australia, causing significant losses in barley yield and quality. Its impact can be reduced with the identification and utilisation of effective sources of resistance. Sixty-nine cultivated barley lines were screened as seedlings against 9 isolates of Pyrenophora teres f. teres from Australia, and in the field in Western Australia. Resistance expressed in seedlings was frequently expressed in adult plants in the field, indicating that these sources are potentially useful for resistance breeding. Of these lines, 24 with the best overall resistance were identified, which could be used against virulence diversity present in P. teres f. teres in Australia.As a prelude to the evaluation of established mapping populations in the Australian Barley Molecular Marker Program, 42 parental lines were screened against a range of Australian isolates of P. teres f. teres. Variation in net blotch responses was observed among parents of the mapping populations. Ten principal mapping populations appear to provide opportunities to map resistances and identify molecular markers linked to NTNB resistance genes effective against Australian pathotypes.

Abstract (sommario):

Winter cereal viruses can cause significant crop losses; however, detailed knowledge of their occurrence in New South Wales, Australia is very limited. This paper reports on the occurrence of Wheat streak mosaic virus (WSMV), Wheat mosaic virus (WMoV), Barley yellow dwarf virus (BYDV), Cereal yellow dwarf virus (CYDV), and their serotypes between 2006 and 2014. Detection of WMoV is confirmed in eastern Australia for the first time. The BYDV and CYDV 2014 epidemic is examined in detail using 139 samples of wheat, barley, and oat surveyed from southern New South Wales. The presence of virus was determined using enzyme-linked immunosorbent assays. The results reveal a high frequency of the serotype Barley yellow dwarf virus - MAV as a single infection present in 27% of samples relative to Barley yellow dwarf virus - PAV in 19% and CYDV in 14%. Clear differences emerged in the infection of different winter cereal species by serotypes of BYDV and CYDV. These results are contrasted to other Australian and international studies.

Testo completo

Abstract (sommario):

Barley (Hordeum vulgare L.) is a major crop in Australia and powdery mildew (Blumeria graminis f. sp. hordei) is one of its most common diseases. Genes for resistance to powdery mildew were postulated for 86 Australian barley varieties and nine advanced breeding lines using 40 reference isolates of the pathogen. Fifty isolates collected in Australia in 2011 were used for additional tests of some varieties. In total, 22 known resistance genes [mlo, Mla1, MlaAl2, Mla3, Mla6, Mla7, Mla8, Mla9, Mla12, Mla13, Mlat, Mlg, MlGa, Mlk1, MlLa, Mlra, Ml(Ab), Ml(Ch), Ml(Dr2), Ml(He2), Ml(Lo) and Ml(St)] were detected. The most frequent genes were Mla8 and Mlg present in 43 and 34 varieties, respectively, while MlGa was found in 12 varieties. Each of the specific resistance genes Mla1, Mla3, Mla6, Mla9, Mla13, Ml(St) and the non-specific recessive gene mlo was found in one variety only. The varieties Maritime and Stirling appear to carry no specific resistance genes. Fifteen unknown resistances were detected. It is recommended that Australian barley breeding programs exploit European varieties possessing mlo to improve the resistance to powdery mildew in new varieties.

Abstract (sommario):

Phenological development in eight cultivars of two-row, spring barley (Hordeum vulgare L.) was examined when sown at two dates of seeding in two diverse environments. These environments were a short-day environment at Northam, Western Australia, Australia, in 1997 and a long-day environment at Lacombe, Alberta, Canada, in 1998. The Australian and Canadian barley cultivars used had different combinations of basic vegetative phase and daylength sensitivity. Barley grown at Lacombe reached each stage of phenological development in less time than at Northam. Most noticeable was a shorter duration of the period between seedling emergence to double ridge and between double ridge and awn emergence. At Northam, nearly 20% of the barley’s life cycle was spent on vegetative growth, just over 40% on ear/stem growth and close to 40% on grain filling. At Lacombe, barley spent nearly 55% of its life cycle filling grain and only 10% on vegetative growth and 35% on ear/stem growth. Later seeding accelerated all stages of development at Northam but only those stages until awn emergence at Lacombe. Late-sown barley at Lacombe took longer to reach physiological maturity. The relative contribution of each phase of crop growth was unaffected by date of seeding. Based on the time to awn emergence, Franklin was a very late flowering cultivar in both environments; Fitzgerald, Gairdner and Manley were late flowering; AC Oxbow and Harrington were mid-flowering; and Stirling was early flowering. Skiff was late flowering at North am but early flowering at Lacombe. Key words: barley (spring), phenological development, daylength sensitivity, basic vegetative phase

Abstract (sommario):

One hundred and fifty-four isolates of the leaf rust pathogen (Puccinia hordei), collected from infected barley plants in Australia between 1966 and 1990, were typed to determine virulence with respect to the resistance genes Rphl to Rph9, Rphl2 (Triumph) and several uncharacterized resistance sources. The Australian cultivar, Prior, reacted differentially to the isolates examined, and is believed to possess a gene which is also present in addition to Rph2 in Reka 1. Virulence and avirulence on Prior were designated P+ and P- respectively. Eleven distinct pathotypes (pt) were identified, with pt 243 P+ and 243 P- predominating in samples collected between 1966 and 1979. In the 1980s, pt 210 P+ was most commonly isolated from samples collected in Queensland and northern New South Wales, and although a range of different pathotypes was present in southern Australia, pt 200 P+ was most frequent in this region. Virulences to genes Rphl, Rph2, Rph4, Rph5, Rph6, Rph8, Rph9 and Rphl2 have been detected, and only Rph3 and Rph7 are likely to be of value in protecting future Australian barleys from the disease.

Abstract (sommario):

Restriction fragment length polymorphism (RFLP) markers were used to determine the genetic structure of Australian field populations of the barley scald pathogen Rhynchosporium secalis. Fungal isolates were collected by hierarchical sampling from five naturally infected barley fields in different geographic locations during a single growing season. Genetic variation was high in Australian R. secalis populations. Among the 265 fungal isolates analyzed, 214 distinct genotypes were identified. Average genotype diversity within a field population was 65% of its theoretical maximum. Nei's average gene diversity across seven RFLP loci was 0.54. The majority (76%) of gene diversity was distributed within sampling site areas measuring ≈1 m2; 19% of gene diversity was distributed among sampling sites within fields; and 5% of gene diversity was distributed among fields. Fungal populations from different locations differed significantly both in allele frequencies and genotype diversities. The degree of genetic differentiation was significantly correlated with geographic distance between populations. Our results suggest that the R. secalis population in Western Australia has a different genetic structure than populations in Victoria and South Australia.

Abstract (sommario):

Studies on variation, occurrence, and distribution of virulence in Pyrenophora teres are helpful to identify effective sources of resistance that can be used for barley breeding in Western Australia. Seventy-nine isolates of Pyrenophora teres were collected from different barley fields of Western Australia in 1995-96. Seventy-four induced net type symptoms (P. teres f. teres) and five induced spot type symptoms (P. teres f. maculata). Net type isolate responses on 47 barley lines were similar to the range of responses induced by nine historical isolates collected in the region between 1975 and 1985. These net type isolates were classified into two distinct groups based on virulence to the cultivar Beecher. Isolates were further classified into eight groups based on minor pathogenic variation among the population. The virulence phenotype present in an eastern Australian isolate was not observed in any isolates collected from Western Australia. An analysis of variance on a subset of 12 net type isolates indicated a significant line × isolate interaction (P < 0.001), with the interaction term variance component four times larger than the error variance. Based on these studies, the virulence among net type isolates has remained stable in Western Australia for the last 19 years. Spot type isolates were collected from a wider geographic area than previously reported and varied in virulence based on response to barley line Herta. Variation in spot-type isolates is reported for the first time from the region. The results from this study are being used in the development of resistant varieties.

Abstract (sommario):

Levels of stem rust (Puccinia graminis) in Australian wheat and barley crops were generally low from 1980 to 1992. Exceptionally wet conditions in South Australia (SA) during early summer 1992-93 resulted in the establishment of vast areas of self-sown cereals, in which stem rust increased rapidly. The disease was also more common in Western Australia during the summer months of 1992-93. Collections from rusted wheat, barley, and selected grass species were analysed in greenhouse tests using an array of differential cereal genotypes. Five pathotypes of P. graminis f. sp. tritici were recovered from SA, 3 of which had not been isolated over the previous 10 years in Australia and for up to 20 years in SA. The recurrence of these pathotypes highlights the need for caution in redeploying resistance genes for which virulence has not been detected for several years. The majority (79%) of isolates taken from stem-rusted barley in SA were either P. graminis f. sp. secalis or `scabrum" rust, both of which do not infect wheat. In total, 6 of 7 isolates of pathotype 21-2,7 recovered from SA came from stem-rusted barley, and as most wheats in this region are resistant to this pathotype, it appears that hosts other than wheat must be important in perpetuating such avirulent pathotypes.

Testo completo

Abstract (sommario):

The main hypothesis tested in this thesis was that poor animal production from saltbush pastures is due to the negative effects of high sodium chloride (NaCl) and potassium chloride (KCl) on the ruminal environment, and subsequent effects on microbial populations and products of rumen fermentation. This main hypothesis was tested in two experiments. In the first experiment (Chapter Four) the effects of saltbush and a formulated high-salt diet on the ruminal environment and microbial populations were measured over 24-hours following feeding. Feeding both the saltbush and high-salt diet increased the salinity of the rumen fluid, but the formulated high-salt diet caused a decrease in ruminal pH while the saltbush caused an increase. This resulted in differences in the composition of the ruminal microbial populations between the sheep fed different diets. In the second experiment (Chapter Five) the effects of saltbush and a formulated highsalt diet on rumen fermentation were measured. Sheep fed saltbush had inefficient rumen fermentation and this was only partially explained by the high salt content of the diet. Diets containing high levels of NaCl and KCl provided low levels of net energy to sheep, but sheep fed saltbush lost more energy as methane and faecal energy compared to sheep fed the formulated high-salt diet. Inefficient rumen fermentation could help to explain poor animal production from saltbush pastures. Energy supplements such as barley grain can improve the value of saltbush pastures as feed for sheep, but there is no information on how much supplement is required. A third experiment (Chapter Six) was designed to test the hypothesis that there would be an optimal amount of barley required to improve the efficiency of rumen fermentation in sheep fed saltbush. Barley and straw were combined in a pellet and substituted for saltbush at 0, 20, 40, 60, 80 and 100% of the maintenance ration. Feeding barley and straw improved the efficiency of rumen fermentation in sheep fed saltbush, with an optimal level of supplementation at 60% of the maintenance diet. This is likely to be lower (approximately 20% of maintenance) if barley is fed without straw.

Abstract (sommario):

The transition to mass emigration by the 1830s coincided with the extension of the British emigrant flows to their furthest extremity, the Antipodes. Australia became a new theatre of migration which reflected the new circumstances of expatriation. The Australian case was famously different from, and began more than a century later than, the great transatlantic migrations from the British Isles. The Australian immigration story was improbable from the start when, in 1788, it began as an extremely remote penitentiary for outcasts from British gaols. The eventual despatch of 160,000 convicts to the Australian colonies between 1788 and 1867 barely merited the name of an emigration system. Like the other Australasian colonies, New Zealand conducted its own assisted immigration policies: many of its immigrants indeed came via Australia, especially during the New Zealand gold rushes of the 1860.

Abstract (sommario):

This chapter presents digital forms of anthropological restitution developed in the late 1990’s and early 2000 by Barbara Glowczewski with different Aboriginal peoples for their own use and a larger audience. She designed the CD-ROM Dream Trackers (Yapa Art and Knowledge of the Australian Desert published by Unesco) with 51 elders and artists from the Central Australian community of Lajamanu in the Northern Territory. Quest in Aboriginal Land is an interactive DVD based on films by Indigenous filmmaker Wayne Barker, juxtaposing four regions of Australia. Both projects aimed to explore and enhance the cultural foundations of the reticular way in which many Indigenous people in Australia map their knowledge and experience of the world in a geographical virtual web of narratives, images and performances. The relevance of games for anthropological insights is also discussed in the paper. Reticular or network thinking, Glowczewski argues, is a very ancient Indigenous practice but it gains today a striking actuality thanks to the fact that our so-called scientific perception of cognition, virtuality and social performance has changed through the use of new technologies. First published in 2002.

Abstract (sommario):

Few women contributed to documenting Indigenous Australian languages in the nineteenth century. Brief accounts are given of six settler women who did so: Eliza Dunlop (1796–1880), Christina Smith (‘Mrs James Smith’; 1809?–1893), Harriott Barlow (1835–1929), Catherine Stow (‘K. Langloh Parker’; 1856–1940), Mary Martha Everitt (1854–1937), and Daisy May Bates (1859–1951). Their contributions are discussed against the background of forty-four other settler women who contributed to language study, translation, ethnography, or language teaching. Reasons for the relative absence of women in language documentation included family demands, child raising, and lack of education, money, and patrons, as well as alternative causes such as women’s rights. Recording Indigenous languages required metalinguistic analytic skills that were hard to learn in societies that lacked free education. Extra obstacles for publication were remoteness from European centres of research, and absence of colleagues with similar interests.

Abstract (sommario):

This chapter highlights Australian-born composer Sadie Harrison’s Easter Zunday (2008). This poem by William Barnes paints a lively portrait of an Easter celebration in the West Country, and is set with artful, infectious relish—an ingenious amalgam of the rustic and the sophisticated. It undoubtedly needs a tenor of special histrionic gifts, one unencumbered by inhibition, able to assume and sustain a ripe Dorsetshire accent with confidence. As the piece nears its climax, stamina will be put to the test—phrases expand, and an exhilarating final surge of energy could prove dauntingly strenuous. The composer’s indications aptly confirm the uplifting spirit of both text and music. Like the voice part, the accompaniment is rhythmically complex, and both performers will need intense concentration in order to coordinate perfectly.

Abstract (sommario):

Obstructive sleep apnea (OSA) is one of the most common sleep disorders. It is characterized by repetitive obstruction of the upper airways during sleep. The frequency of such events can range up to hundreds of events per sleep-hour. Full closure of the airways is termed apnea, and a partial closure is known as hypopnea. The number of apnea/hypopnea events per hour is known as the AHI-index, and is used by clinical community as a measure of the severity of OSA. OSA, when untreated, presents as a major public health concern throughout the world. OSA patients use health facilities at twice the average rate (Delaive, Roos, Manfreda, & Kryger, 1998), causing huge pressures on national healthcare systems. OSA is associated with serious complications such as cardiovascular disease, stroke, (Barber & Quan, 2002; Kryger, 2000,), and sexual impotence. It also causes cognitive deficiencies, low IQ in children, fatigue, and accidents. Australian Sleep Association reported (ASA, 1999) that in the state of New South Wales alone 11,000–43,000 traffic accidents per year were attributable to untreated-OSA.

Abstract (sommario):

Roan and Diamond (2003) claim that labour market policy in Australia has focussed on the provision of employment and the preparation of young people for employment but entirely neglected quality of working life issues. The same may be said for other developed economies’ labour market policies. In the anguish to get young people into work, which is understandable given the youth unemployment crisis, the nature of work itself has, until recently at least, rarely been questioned. In the run up to the May 2015 UK general election, rival parties were at loggerheads over the nature of jobs being created in the economy, with the ruling coalition parties pointing to the fall in unemployment and the opposition arguing that many of these jobs were barely paying the minimum wage and that furthermore many of the jobs now being offered were on zero-hour contracts and also on casual contracts, which are ones where the employer can hire staff without the guarantee of work. Suddenly the nature of work reappeared on policy makers’ agendas and this, coupled with tourism’s admittedly poor reputation as an employer, suggests the need for a closer look at the nature of youth employment in the sector. Consequently, this chapter presents and discusses different characteristics of youth employment in tourism and hospitality. It aims to provide an insight into the experience of youth employment as well as reviewing the role of trade unions in improving working conditions for young people. The chapter also addresses separately the nature of youth employment in developing countries, and concludes with a review of the relationship between responsible tourism and youth employment.

Abstract (sommario):

The helplessness of newborn babies is very endearing. They can just about breathe unaided, but they are otherwise entirely unadapted and dependent. Babies can barely see, let alone walk or talk. Few animals come into the world so unprepared, and no other species is as dependent on learning as human beings are. Elephant calves, for instance, can stand up by themselves within a few minutes of being born. Most animals are similarly “preprogrammed.” Female elephants carry their young for no fewer than 22 months, whereas we humans have to go on investing in our offspring long after they are born. Children need years of adult protection. They guzzle fuel, too; their brains consume fully 60 percent of the newborn’s total energy intake. In the first year of life, the infant’s head buzzes with activity as neurons grow in size and complexity and form their innumerable interconnections. The way the brain develops is the subject of the next chapter (chapter 5.2). Here we concentrate on the way we are educated from the first day on. There is virtually no difference between Inuits and Australian aborigines in terms of their ability—at opposite ends of the earth and in climates that are utterly different—to bear children successfully. Other animal species are far more closely interrelated with their environment. Other primates have evolved to occupy a limited biotope determined by food and climate. Humans are much more universal. Every human child has an equal chance of survival wherever they are born. As a species, we delay our maturation and adaptation until after birth, which makes the inequality of subsequent human development all the more acute. Someone who is born in Mali or Burkina Faso is unlikely ever to learn to read. A person whose father lives in Oxford, by contrast, might have spoken his or her first words of Latin at an early age. Inuit and aboriginal babies may be born equally, but their chances begin to diverge the moment they start learning how to live. We are not shaped by our inborn nature but by the culture that is impressed upon us by the people with whom we grow up.

Abstract (sommario):

The idea of using float-over installations for minimal facilities platforms was shown to offer significant advantages, especially when coupled with a substructure installed by a jack-up rig. Recently, float-over installations of minimal facilities have been conducted by the cantilevered method by ICON Engineering Pty Ltd (ICON). The operation involves the platform topsides being loaded and transported to site on a barge, skidded over the barge bow, and lowered onto the jacket. The paper presents results of a research project undertaken by the Australian Maritime College (AMC) in conjunction with ICON, with the objective to investigate motions of a barge and loads exerted on the jacket when the two are docked together for a smooth load transfer operation. The model of an installation barge has been tested in the AMC wave basin and response amplitude operators of the barge motions have been determined for both the free floating and docked conditions. A range of wave periods and heights has been investigated. Model test results have been used to verify numerical predictions used in the design, and to get insight into uncertainties, which may otherwise be difficult to assess using standard software.

Abstract (sommario):

Underground Coal Gasification (UCG) is a gasification process carried on in non-mined coal seams using injection and production wells drilled from the surface, converting coal in situ into a product gas usable for chemical processes and power generation. The UCG process developed, refined and practiced by Ergo Exergy Technologies is called the Exergy UCG Technology or εUCG® Technology. The εUCG technology is being applied in numerous power generation and chemical projects worldwide. These include power projects in South Africa (1,200 MWe), India (750 MWe), Pakistan, and Canada, as well as chemical projects in Australia and Canada. A number of εUCG based industrial projects are now at a feasibility stage in New Zealand, USA, and Europe. An example of εUCG application is the Chinchilla Project in Australia where the technology demonstrated continuous, consistent production of commercial quantities of quality fuel gas for over 30 months. The project is currently targeting a 24,000 barrel per day synthetic diesel plant based on εUCG syngas supply. The εUCG technology has demonstrated exceptional environmental performance. The εUCG methods and techniques of environmental management are an effective tool to ensure environmental protection during an industrial application. A εUCG-IGCC power plant will generate electricity at a much lower cost than existing or proposed fossil fuel power plants. CO2 emissions of the plant can be reduced to a level 55% less than those of a supercritical coal-fired plant and 25% less than the emissions of NG CC.

Abstract (sommario):

Tension Leg Platforms (TLPs) are ideal supports for dry-tree top tension riser systems because their tendons exhibit high tensile stiffness and significantly reduce the heave, pitch, and roll motions of the platforms. Since the first TLP (Hutton) was installed in the North Sea in 1984, a total of 24 TLPs have been installed throughout the world with 16 of them installed in the Gulf of Mexico. Currently there are new TLP projects proposed in regions off the coast of Malaysia, West Africa, Brazil and Western Australia. Heavy-lift vessels were used to install tendons for most of these TLP’s. Tendon joints were assembled vertically from bottom part to top part. Using a heavy-lift vessel introduces significant cost and schedule challenge to TLP projects, especially ones located in remote regions. A horizontal tendon installation methodology is presented in this paper. This innovative approach involves horizontal assembly of TLP tendon segments on a construction barge. The partially assembled tendon is then incrementally pulled out through a stinger at the barge stern and secured with a hold back clamp so that the next tendon joint can be connected. The process repeats itself until the whole tendon is assembled and deployed. The tendon is then upended to a vertical configuration and connected to a TLP or a foundation pile. In this paper, we examine the alternative equipment and configuration options in the horizontal installation methodology. We outline rationales to select the appropriate options and measures to reduce project cost and risks.

Abstract (sommario):

Vortex induced vibration (VIV) due to steady current flow can be a significant driver in the design of offshore riser systems, affecting riser global configuration, component details and overall subsea architecture. Helical strakes are known to reduce VIV but the degree of effectiveness can vary considerably depending on strake pitch, fin height and more importantly, current flow regime. In addition, the amplitude of VIV and the effectiveness of VIV suppression strakes depends on the inclination of flow to the riser (incidence angle) and presence of wake effects from adjacent risers. Test and field data regarding suppression of riser VIV by strakes is not extensively available in the public domain. This is primarily due to the proprietary nature of the tests conducted in industry. In this paper, a program of testing is devised to better understand strake effectiveness as a function of current incidence angle and the presence of adjacent risers. Experiments have been conducted on single and tandem pipe arrangements in air in order to evaluate strake suppression efficiency. Aluminium cylinders are tested in a wind tunnel in the structures laboratory of The University of Western Australia (UWA). Two sets of experiments are conducted: the first to evaluate cylinder VIV response at angles of incidence ranging from 30 to 90 degrees and the second to evaluate VIV response of the downstream pipe in a dual pipe arrangement with varying spacing between the pipes. In both cases the bare cylinders are first tested at varying flow speeds. Helical strakes are then added to the single cylinder, and downstream cylinder in the tandem pipe test, and the vibration response is recorded at varying flow speeds. From the experimentation, it can be seen that downstream cylinder motions are amplified by wake induced instability. This phenomenon is of particular concern for tightly spaced top-tensioned risers (TTR) in wellbays of tension leg platforms (TLP) and deep draft floaters. The VIV motion of the downstream, bare, wake-affected pipe, is magnified to approximately 1.3–2 times the motion of a single bare pipe. When strakes are added to the downstream cylinder, the magnification factor of the downstream cylinder response is largely increased due to the wake of the upstream bare cylinder. However, the actual VIV motions of the downstream cylinder are largely reduced when strakes are incorporated. The present work demonstrates that helical strakes provide an effective means of suppressing vortex induced vibrations of risers in riser arrays, though the degree of effectiveness is reduced in a downstream tubular compared to suppression levels for single pipes.

Abstract (sommario):

Conventional pipelay (i.e. S-lay) is not feasible in shallow water locations owing to the draft of pipelay barges. Pipelay using beachpull method provides an alternative to such restrictions. A typical long beachpull operation in shallow water environment presents a substantial challenge, which calls for a thorough engineering analysis along with a detailed installation procedure. This paper highlights the methods and techniques of pipelay using beachpull method that were employed on the John Brookes joint venture (Apache and Santos) and the Aramco Karan project. The John Brookes project (Varanus Island, Australia) included the installation of a landfall section comprising an 18” FBE coated pipeline featuring a beachpull length of 7.0 km, one of the longest of its kind. The Karan project (Saudi Arabia) comprised the installation of a 38” trunkline, requiring a beachpull length of 3.0 km and also the installation of a 15kV cable having a beachpull length of 4.0 km. Beachpull engineering comprised checking the pipeline’s lateral stability under the influence of near-shore current-induced hydrodynamic forces. For the Apache Project, the 7.0 km long beachpull coupled with the proximity to the existing pipeline and near-shore currents offered a unique challenge. Supplementary buoyancy was utilized to limit the required beachpull tension within allowable limits. The drifting of the pipeline from the installation corridor was restricted by installing sand-filled bulker bags at designed intervals. The beachpull installation on the Karan project offered a different challenge owing to a larger pipe size and a piggybacked cable in a shallow water depth. Special consideration was given to the attachment of supplementary buoyancy bags and dynamic loadings that were acting throughout the beachpull length, especially during cable installation. This paper describes the technical challenges faced during the estimation of the pull-in loads and weather-induced lateral displacements encountered during the beachpull. This paper also elaborates the assessment of proposed winch, design of supplementary buoyancy, design of bulker bags, etc. Data collected on-site during installation of the pipelines are in good agreement with computed / designed values, ensuring the correctness of the beachpull simulations. Detailed engineering studies along with well developed installation procedures resulted in successful completion of the installation.
