Maintenance optimization on merchant ships
AuthorsG Coletta ; G Guassardo ; A Vergine
Date published2000
AbstractTraditionally maintenance on board ship has always been carried out empirically mainly based on the recommendations of the manufacturers and/or the requirements of the Classification Societies. This approach does not necessarily lead to the minimization of the life cycle costs of the ship. The aim of this paper is to demonstrate the potential for optimizing the maintenance costs when the operating data already available in the onboard maintenance management software are correctly interpreted statistically and used in the appropriate models.

Numerical study of solitary wave on a mild slope
AuthorsC-R Chou ; O Kwan
PublisherInternational Society of Offshore and Polar Engineers
AbstractA numerical simulation of wave breaking by a boundary element method to assess generation propagation deformation and breaking of the solitary wave on a mild slope has been developed. The numerical scheme is based on Lagrangian description with finite difference approximation of the time derivatives. Simulation involved solitary wave propagation from constant depth over a mild slope. Time history of the solitary wave propagation is shown and the numerical results of mass potential energy and kinetic energy of the fluid are presented.

Numerical study on the far field diffusion of ocean dumping for liquid waste
AuthorsB-S Shiau ; J-J Juang
PublisherInternational Society of Offshore and Polar Engineers
AbstractThe far field phase diffusion of discharging liquid waste into the sea water was investigated. Diffusion in the far field phase was simulated by three dimensional turbulent diffusion equations. The moment method was used to integrate the governing equation. A numerical model was developed to solve the equations. The effects of current speed and ocean diffusive characteristics on the diffusion of liquid waste concentration were calculated. Calculated results indicated that ocean diffusivity had a strong effect on the diffusion and spread of the liquid waste cloud.

On assessment of existing offshore structures
AuthorsGerhard Ersdal ; Ivar Langen
Date published2002
AbstractThe assessment of existing structures is carried out to extend the service life of a facility as new methods of production and new discoveries may extend the life of a field. The methods normally used to assess existing offshore structures are based on design level check ultimate strength check or on a probabilistic approach. There are arguments against all these methods. The procedures for safety assessment of existing offshore structures described as given in ISO 13819-1 (ISO 1995) API RP2A-WSD (API 2001) ISO/DIS 13822 (ISO 2000) and ISO/CD19902 (ISO 2001). The procedures are presented and discussed and how they are capable of being measured against a goal of even and acceptable risk for the society.

On board training record book for cadets 2nd edition
AuthorsInternational Shipping Federation
Shelf Location234d
AbstractThe 1995 amendments to the IMO Convention on Standards of Training, Certification and Watchkeeping for Seafarers (SCTW) stipulate that approved seagoing service for deck officers has to be recorded in a training record book. ISF training record books are recognised in the footnotes to the STCW Convention as a model for such documentation. This ISF On Board Training Record Book for Deck Cadets incorporates the competence standards for the Deck Department specified in Chapter 2 of the revised STCW Convention.

On the stimulation of the tidal exchange of an enclosed coastal sea
AuthorsYusaku Kyozuka ; Tadaaki Shima
Date published1999
AbstractA basic study on the stimulation of the tidal exchange of an enclosed coastal sea by the configuration of the bay opening or the installation of offshore structures is presented. The tidal exchange characteristics of a small bay is considered using numerical simulation and a model experiment on the breadth position and shape of the opening of the bay. After some introductory information and a brief outline of the model bay a look is taken at the numerical simulation followed by the model test.

Paper charts to E-Hydrography - a New Zealand perspective on five years of change
AuthorsDavid Mole ; John Spittal
Shelf Location214c
AbstractThe events that have influenced New Zealand's national hydrography from 1996 to the present are outlined. Successes are evaluated as well as the areas that could have been improved and future opportunities are highlighted. Particular emphasis is placed on the impact of the New Zealand Government's e-government policies and strategies on both hydrographers and mariners. A diverse range of drivers of change is drawn together and a cohesive model for progress is formed.

Phenomenological model of propeller blade-ice interaction and method for determination of ice loads on the propellers of icebreaking ships
AuthorsV A Belyashov
Date published2001
AbstractAs ships move through ice their propellers are exposed to significant ice loads causing damage to the blades and other parts of the propulsion system. A new method is presented to numerically evaluate ice loads on propeller screws. This method is based on the new phenomenological model of the interaction of the blade with ice.

Prediction of hydrodynamic forces on a high-speed catamaran in a seaway
AuthorsM Ohkusu ; O M Faltinsen ; M Yasunaga et al.
Date published1994
AbstractA practical method to predict hydrodynamic forces on a oscillating catamaran moving at high speed through waves is presented. The method predicts that dominant diverging waves will be created by assuming large flow variations along the ship's length. Chapman's approach is used to solve the boundary value problem for the unsteady velocity potential around the twin hull. Results showed that the predicted hydrodynamic forces agree at high Froude number with measurements taken on a model although the results for the diffraction wave field around the ship differed from model measurements.

Probabilistic analysis of live loads on offshore platform piles
AuthorsHassan Zaghloul ; Beverley Ronalds ; Geoff Cole
Date published2005
AbstractThe objective of this study is to obtain a better understanding of open area live loads on offshore platforms and develop a methodology to obtain the long-term and extreme open area live load. A load survey was conducted for the purpose of this study and a probabilistic analysis was carried out to derive the maximum axial load on piles that is expected during platform lifetime. The results of this study indicate that the use of a single value for the open area live load (OALL) may not be appropriate and suggest appropriate values for Load Resistance Factor Design (LRFD) or Working Stress Design (WSD) methods.

Reliability Evaluation of Evacuation Pipes on the Troll GBS
AuthorsE H Cramer ; E T Moe ; O Krog
Date published1998
AbstractThe paper shows how structural reliability methods can be a valuable tool in attacking complex engineering problems associated with uncertainty. Special attention is paid to the aspects of uncertainty modelling and the use of additional information from tests and measurements in the probabilistic modelling. The probabilistic study confirms that the GRVE evacuation pipes on the Troll GBS have a not insignificant risk for leakage caused by clipping during the installation phase. The study shows further that by carrying out remedial action on only a limited number of the pipes the strictly defined safety level requirement is met.

AuthorsA Millward
Date published1982
AbstractA linearised theory for calculating ship resistance is used to determine the effects of various depths of shallow water on hulls of different shapes and draughts moving at speeds from sub to super critical. The theoretical predictions are compared with previously published experimental work on planing and round bilge displacement hulls.

The effect of using an additive on the combustion behaviour and soot emission of marine fuels
AuthorsT Reynolds ; T Graczyk ; T Jastrzebski et al.
PublisherComputational Mechanics Publications
AbstractThe ERC company has commissioned a study into the effect of one of its additives on the combustion of heavy oil and exhaust-gas emission. The additive was tested during combustion in a slow-revving 2-stroke cross-head diesel engine 6RTA72 on board a seagoing container ship. The results indicated that with the additive the combustion was completed sooner and the combustion turnover lessened with process and exhaust- gas temperatures reduced also. In addition lower soot (exhaust gas) emission was recorded.
