Geomorphic - biotic interactions on beach foreshores in estuaries
AuthorsNancy L Jackson ; Karl F Nordstrom ; David R Smith
Date published2002
AbstractAn attempt is made to identify what is known about the linkages between geomorphology and biota on estuarine beaches and suggest areas for future investigation primarily using examples based on research in Delaware Bay USA. After some background information a look is taken at morphologic and sedimentologic changes. Next effects of shore protection methods are considered followed by future assessment.

Long term full-scale measurements on the strength of ships
AuthorsA Nitta
Date published1984
AbstractThis paper describes summarised results of full-scale measurements on the strength of four ships. The tests have been carried out since 1973 by the Research Institute of NKK as a part of the long term research programme. The results of the measurements have been compared with theoretical predictions obtained by a relevant structural analysis on each ship.

A discussion of the effect of the reeled installation process on pipeline limit states
AuthorsS Manouchehri ; B Howard ; S Denniel
Date published2008
AbstractThis paper addresses systematically the effect of the reeling process on pipeline operational integrity. This is done by assessing the effect of reeling on each limit state that could result in pipeline failure namely pressure containment (burst) hydrostatic collapse and fracture. Effect of reeling on the global buckling (beam buckling) and local buckling (shell buckling) behaviour of pipe is also discussed.

A research on fast mixing combustion process
AuthorsZ Wang ; L P Zhang ; Z Z Cai et al.
Shelf Location215e
AbstractResearch into a fast mixing combustion process on a single cylinder diesel engine on which the inlet and exhaust condition of multi-cylinder turbocharged engine are simulated is introduced. Firstly the test and measurement instrument is outlined. Next organization for fast mixing combustion process is looked at. After this experimental research of FMC process on the single cylinder engine is considered. Lastly analyses and evaluation for FMC process are discussed.

Battleground on the safety case front
AuthorsJOT
Shelf LocationContact IMarEST directly for access
AbstractImprovements and problems in implementing Safety Case Regulations post- Piper Alpha are discussed. Recent transfer of responsibility for offshore safety to the Health and Safety Executive (HSE) has meant an increase in overall safety standards through enforcement of new legislation and individual safety cases for offshore platforms which means greater burdens on operators. Contention between the UK Offshore Operators' Association (UKOOA) and the HSE over regulations on pipelines helicopters drilling and the inclusion of trade unions on safety committees are highlighted.

Development in operating practices on FPSOs
AuthorsB McCammon
Date published1995
AbstractThe changes that are being brought about on BHP Petroleum's operations with floating production storage and offloading (FPSO) units in the Timor Sea and on the North West Shelf of Australia are discussed. The changes are focused on improving safety and the working environment for employees and have been driven by the introduction of the safety case regime and the development of a management system offshore. The historical development of FPSO facilities are outlined and the organisational structure of employees is reviewed. The requirements of the safety case are discussed and the future organisation of FPSOs is then presented.

AuthorsA Koschinsky ; H Gerber ; A Szemeitat
Date published1997
AbstractGeochemical experiments with deep-sea sediment cores are presented. These investigations are part of the activities of the German TUSCH cooperative project which was set up to study the problems which might arise from a future commercial use and exploitation of the deep-sea. First a look is taken at technical development and equipment. After this the geochemical experiments are considered including the results.

Hatch covers on bulk carriers: the effect on procurement costs of changes in design pressure
AuthorsDavid Byrne
Date published2001
AbstractFollowing the Re-opened Formal Investigation into the loss of MV Derbyshire several studies have been conducted to better understand the adequacy or otherwise of the existing international regulations for hatch cover design and to consider palliative measures. An attempt is made to provide reliable cost data for various proposed measures by which the structural reliability of hatch covers may be improved especially increased design pressures (sea loads).

Infragravity wave frequency structure on a doubled-barred beach
AuthorsNadia Senechal ; Philippe Bonneton ; Helene Dupuis
Date published2002
AbstractAn attempt is made to report observations of infragravity energy on a double-barred beach situated on the French Atlantic coastline in the presence of a low energy narrowband and long swell but also in the presence of high secondary wave generation due to nonlinear triad interactions. Emphasis is placed on the evolution of the frequency structure of the infragravity band. After some introductory information a look is taken at the study area materials and methods. Next results are considered and discussed.

Measurement of pressure distribution on a full scale propeller - measurement on a highly skewed propeller
AuthorsY Ukon ; T Kudo ; Y Kurobe et al.
Date published1994
AbstractPressure distribution measurements of a highly skewed propeller are compared to theoretical results using an estimated nominal full scale wake distribution. Measured results agreed with the theory most of the measurement points especially in the fore part of the blades. However the measured pressure at 90% radial position tended to decrease toward the trailing edge a result which differed from the theory. This suggested that the hydrodynamic load at 90% radial position might cause the propeller tip to break due to rapid fatigue crack growth.
