In the past dynamic research on planing ships has analysed ships' motions in three or four degrees of freedom. Delft University of Technology and MARIN have now started to describe dynamic behaviour using a six-degree model. The work involves developing a six-degree computer simulation program in the time domain and conducting still-water static tests of two planing hullforms in the towing tank at Delft. The set-up of the mathematical model is presented and the use of the static tests is discussed.

The emission characteristics of PM (particulate matter) from marine diesel engines are investigated to evaluate PM emission from ships. PM shows different emission characteristics for four-stroke and for two-stroke engines. Chemical aspects of PM also show differences with engine type and operating conditions. These differences are expected to be due to combustion conditions engine specification or fuel quality. Onboard PM measurement is carried out to measure PM emission characteristics from cruising ships. The evaluation of PM emissions based on ship performance is proposed with the results of onboard measurements. The application of a new PM measurement method to marine diesel engines is also been attempted.

An examination of the US Navy's shipboard pollution abatement programme that will enable 21st century ships to operate worldwide with minimal potential for regulatory constraints without inappropriate dependence on shore facilities and unreasonable costs imposed by environmental regulations. The strategy is to design and operate ships to minimise waste generation and optimise waste management and develop shipboard systems that will destroy or appropriately treat the wastes generated onboard. Topics include disposal of the wastestream treatment of oily wastes hazardous materials medical waste blackwater and greywater. The constraints of developing adequate systems are discussed and some possible solutions and designs are given along with mention of different international co-operative efforts.

This Guide has been prepared by the American Bureau of Shipping to assist owners in the reactivation of ships laid-up in accordance with this Society’s published guide. These guidelines are of a general nature due to vessel configuration, and geographic and climatic condition of lay-up site and degree of maintenance during lay-up and are therefore intended solely for guidance purposes.

This illustrated guide, which is supported by flow charters, checklists and other aides-mémoire, describes port State practice as it stands today. Advice is also given on how to manage inspections. Improving the inspection performance of ships through a better understanding and awareness of port State control practice is one aim of this guide. Lack of consistency, varying performance and poor practice by Port State Control Officers in conducting inspections remains a concern of ships and shipowners. In order to seek feedback and attempt to quantify the situation, an Inspection Reporting Form forms part of the guide.

This booklet contains recommendations by the Admiralty Ship Welding Committee for the guidance of ship repairers, inspectors and foremen engaged in the repair of ships' structures by welding. It covers planning for repairs, removal of damaged material, joint preparation, welding sequence, welding procedures, holding parts in position for welding, workmanship, and organisation and supervision.

Energy-efficient ships with low emissions can only be achieved by the selection of proper components and sub-systems. A complete approach considering the whole life cycle of the ship is recommended. Future industrial processes are characterised by low energy consumption low emissions and cleaner products. Safe operation of ships depends on the selection of the right components sub-systems and systems. The European Maritime STEP (Standardised Product Model) Association (EMSA) initiative could be a contribution to quality assurance in the medium and long term. The ship should be treated as a total system; hulls and materials machinery propulsors and auxiliaries are discussed.

This looks at the ships employed in the South Sea whale fishery from Britain in the years 1775 to 1815. Chapter 1 looks at history, geographical expansion, significant political influences, development of global networks, commercial considerations and economic spaces,. Chapter 2 outlines the sources used. Chapter 3 gives an alphabetical list of ships and Chapter 4 an alphabetical list of owners and merchants engaged in the fishery.

The effect of ships' main characteristics on the values and rates of wear distribution along the hull is investigated. Statistical data is summarized for ten Russian ships ranging from fishing seiners to the largest icebreakers. Based on the results of this a formula was suggested to determine the wear rates depending on the given ice pressure in a region under consideration. Results of this work can be used for a ship's hull painting and shell plating thickness design.

Part 2, Details of Ship Construction, contains the following chapters: Outside shell, deck and inner bottom plating, Bottom assemblies, Deck assemblies and platforms, Structural arrangement in way of openings, Side assemblies, Bulkheads, Superstructures, Stems, sternposts, shaft struts and bossings, Foundations and Other elements of the hull.

The book aims to explain the fundamental principles of automatic stabilisation of ships and examines various gyroscopic systems. Chapters included are as follows: Waves and the rolling of ships, The Frahm anti-rolling tank system, Elementary theory of the gyroscope, Gyroscopic stabilisation, The Schlick gyroscopic system, The Sperry gyroscopic system, Stabilisation by twin gyroscopes, The Fieux gyroscopic system and The Deparis and the Motora systems.

Part 1 of this reference book covers Marine Diesel Engines, with information on companies such as Doxford, the English Electric Company, Harland and Wolff and Werkspoor. Part 2 looks at particular Motor Ships such as the Mai Bente, Centaur, Toula, Vinci, Brielle, Bilu and Westrider, included in sections on bulk carriers, cargo and cargo-passenger liners, fishing vessels, tankers, general purpose ships, passenger liners, and tugs and icebreakers.

This is the second in a trilogy of papers addressing the findings of Lloyd’s Register’s studies on the nuclear propulsion of merchant ships: the first being presented at Lloyd’s Register’s Technology Days 2010. This paper first considers the underlying physics of nuclear propulsion and then explores the application of that science to the propulsion of merchant ships. In achieving this aim the paper examines the options for the exploitation of nuclear technology and considers some of the engineering implications of deploying the technology.

The safety of large passenger ships is discussed. The role of the International Maritime Organisation (IMO) in addressing safety and environmental issues is explained: various subcommittees deal with different aspects of safety. The current view of the IMO is that a holistic approach should be adopted. The MSC (Maritime Safety Committee) has established a working group specifically to examine the safety of large passenger ships and its terms of reference are listed.

In this report flooding calculations using the probabilistic method on the basis of IMO resolution MSC.19(58) and explanatory notes to the regulations on subdivision and damage stability of dry cargo ships including roro ships in SLF 33/12 and SLF 34/WP.9 are explained.

Technical and developmental aspects of high capacity electrical systems for ships discussed with illustrative examples of dc installations (mostly prior 1950) low voltage three phase systems and medium voltage systems. The concept of `high capacity' expected loads especially in large ships costs economic and choice of system are considered.

Recent experience with microprocessor - based machinery surveillance and control systems for surface ships and submarines of the DG ships directorate of the UK Royal Navy is described

High-speed ships have been developing quickly over the past few years. Meanwhile there have also been advances in the types of aluminium alloy material available. The use of aluminium alloy in ships is discussed and the advantages of ribbed aluminium sheets are analysed. Some structural design questions are also discussed. Conclusions are drawn.

The significant loss of ships through fire in the period 1976-1980 coupled with the trend towards larger ships bigger engine rooms more cargo smaller crews and hazardous cargos give cause for concern. The predominance of engine room fires leading to loss of ship is especially discussed and causes detection systems siting and alarms and extinguishing equipment are described.
