Results of a Lloyd's Register study into the fire hazard electric cables pose due to their shipboard configuration. Although SOLAS and IEC standards require cabling to be flame retardant cables pose a threat because of combustible insulation and sheathing materials potential for heat and sparks and ubiquitous installation. Studies of geometric cabling arrangements and the flammability of different cable types and manufacturers showed that fire propagation is lessened when large bunches of 16 or more cables are used the gaps between bunches is 6cm or more and cables are configured in horizontal runs. The use of flame retardant cable does not guarantee flame retardation on ships.

Four merchant ships (general cargo. passenger cargo tanker) fitted with various Doxford diesel engines (specially designed or modifed to operate on residual fuel) were monitored during service for engine performance cleanliness and liner wear. The results were correlated with analyses of as-bunkered and treated fuel and sludge. Engine test bed trials using diesel and heavy fuel are also reported.

The advantages of electrical propulsion are widely acknowledged but connecting a ship's service to large semi-conductor equipment creates supply disturbances such as harmonics. The ways of preventing harmonics from affecting ships' services are considered with particular attention to specific constraints including fluctuations of supply frequency variation of short circuit power changes in the current's harmonic spectrum and the functional availability of equipment. The effect of each constraint on passive and active filters is examined. The results of harmonic compensation with an active filter are presented.

The scope of this book includes merchantmen and men-of-war, ceremonial, pleasure and trading craft of all civilisations and ages, as well as the people who built and sailed them. This revised edition brings the story up to date, including a chapter on the new challenge to marine engineering posed by the discovery of oil under the sea. On the naval side, there is an examination of the lessons to be learned from the recent war in the Falklands.

This paper describes qualitative and quantitative methods for assessing the reliability/availability of ships' machinery. An analysis of a fuel oil system demonstrates the need for caution in the initial definition of failure. The statistical approach is compared with the physics of failure approach in which fatigue considerations play a major part. The effects of variable hazard rates in marine diesel engines are shown to be significant. A comparison is made between a direct drive and a geared engine propulsion system.

The use of electric drives over the past century is reviewed focusing on their use in ice breaking ships where most of the significant developments were made between the 1930s and the 1980s. Future developments such as the US Navy's Advanced Surface Machinery Programs and recent developments in the application of magnetohydrodynamics (MHD) to experimental ship propulsion are also discussed. Topics include electric drive attributes electric propulsion systems for icebreakers the development of cycloconvertor systems thyristor controlled systems the AC/AC icebreaker Otso shaftline design principles the nuclear icebreaker Taymyr the tanker Uikku pod driven vehicles and future possibilities.

Some new requirements of 1981 amendments and relevant interpretations necessary for application to ships with regard to fire protection fire detection and fire extinction are examined.

The A/A max calculation procedure outlined in IMO's MSC/Circ 574 `The calculation procedure to assess the survivability characteristics of existing ro-ro passenger ships when using a simplifed method based upon resolution A.265 (VIII)' has shown some drawbacks which can give paradoxical results. The case for a one-compartment ferry and two- compartment ferry are described and conclusions discussed.

The SpecTec Group has supplied more than 2000 computerised Planned Maintenance Systems (PMS) onboard ships. The ISM Code requests the implementation of planned maintenance onboard vessels and the advantages of these systems are well known. Computerising the management of a fleet involves maintenance control spare parts control purchasing control and documentation control. The main problems with implementing a systems are human related and include training and resistance to new practices. An example is given of one of the largest container operators in Italy using the Administrative Maintenance and Operation System (AMOS-D).

The Structural Acoustics Group at DERA has been involved in developing modelling tools for radiated noise predictions for the Royal Navy. The methodology of designing a quiet ship is described and the Statistical Energy Analysis technique is presented as one of the useful design tools to quickly assess the internal and radiated noise at the early design stage. After some background information a look is taken at the radiated noise estimation tool. This is followed by consideration of noise control methodology.

This is a Fairplay report, dividing chapters between those of technical matters and those of commercial importance. Contents cover a brief history of ro-ro ships, ship propulsion, ship structural considerations, ship safety, ro-ro access, cargo handling - equipment and operations, ro-ro ship types, short sea/coastal services, deep sea services, and potential areas for ro-ro including the Caribbean, West Africa, the Middle East, the Far East and South America. There is also a chapter on fleet development.

This book is written for an informed maritime readership, but one which may not have a detailed knowledge of financial practices employed in the complex world of ship finance. This is a practical handbook in which the procedures and terminology are fully covered. Both new and secondhand craft are covered, while the book details the financial appraisal of new projects, the use of foreign currency, taxation and leasing and other subjects vital when the purchase of ships or rigs are considered.

The SWIM project is a 3 year project to investigate the effects of high speed craft's wash with the results due mid 2003. The investigation will assess wash impacts on environmental quality and safety and will develop better capabilities to predict wash generation by high-speed ships. The results should provide an improved basis for the regulation and planning of high-speed craft operations. The project involves direct collaboration between academic and industrial expertise to exploit complementary expertise maintain focus on objectives ensure high quality standards and best value for money. An overview of the project background and the 5 main work packages that make up the project are outlined.

Highly skewed controllable pitch propellers (CPPs) of KaMeWa's design and manufacture have been installed in nearly one hundred large passenger ships since their market introduction in 1977. This paper describes the main characteristcs and design principles for this type of propeller. Some results from cavitation tunnel model tests are presented. The essential service experience gained in full scale is summerised.

The application of artificial intelligence (AI) approaches to the modelling navigation and control of surface ships is considered. Researchers at the University of Plymouth have shown the viability of designing an intelligent ship autopilot which can effectively provide robust control for a large range of both vessel and environmental parameters. Other areas in which the research into marine application of artificial intelligence continues are outlined. First the elements of an intelligent machine are looked at. Next the ship as an intelligent machine is discussed.

The production and environmental factors that influence the coating process in shipyards are reviewed. Those areas where shipyards commonly have problems in managing the coating process are identified and some of the opportunities for improvement are described. Historically the painting process has been afforded no weight in the real task of building ships and only little weight in the planning process. However it is responsible for the majority of re-work waste and environmental concerns of a shipyard. The historical perspective is tackled followed by a review of the production process cost penalties and improvements to the coating process.
