In this paper an attempt is made to include crew safety in the preliminary ship design as an explicit node or condition. In this preliminary study the goal was to design ships with improved seakeeping characteristics. The procedure followed is based on the use of an expert system shell Echidna which has features that make it more suitable for design in general. In theory any nonlinear solution solver that includes inequalities and equalities could be used to design a ship. Echidna's built in logic is able to handle constraints that is the ability to reduce the design space through propagating constraints on the corresponding design parameters. The applications presented in this paper are the development of a code in Echidna to design a displacement type boat suitable for the Pacific coast of Canada. The application of the Expert System shell is based on standard nodes equations and/or constraints of ship design. The shell is expected to find a solution within the constraints specified. The Echidna Expert System usually is able to find a solution and supply the result as a range for the ship parameters.

The purpose of the book is to outline the methods adopted in the various areas of ship design. Contents include chapters on: design factors and parameters, lightship weight and power estimation, cargo capacity estimation, hydrostatic particulars and stability, hull form and design, crew and passenger accommodation, classification, freeboard, subdivision and tonnage, choice of propelling machinery, powering and propellers and ship and marine engineering research.

The advantages and disadvantages of China's entry into the WTO are considered. How China should then confront challenges brought about by this entry is then discussed. The positive action that China's ship-repairing enterprises should take is then identified. It is concluded that China's ship-repairing industry is capable of grasping opportunities and confronting challenges to carry forward China's ship-repairing industry in a short time in order to open a way of Chinese ship repairing to the international ship-repairing market.

The book reviews ship types, their construction, special features and outfit requirement. Shipbuilding techniques are described and the ship as a stressed structure is examined. The major items and regions of structure are illustrated in detail and types and methods of strengthening and stiffening are explained. A chapter is devoted to the special construction requirements of oil tankers, liquified gas carriers and bulk carriers. The final chapters deal with the corrosion process and the preventive methods employed for the ship's structure, and with the examination of ships in dry dock, periodical surveys and maintenance.

This paper deals with the numerical estimation of ship-generated waves developed in the author's previous work. The wave patterns around a ship are computed. The numerical calculation of ship waves is conducted by applying the numerical technique for computing the viscous flow past a ship hull with free surface. The calculated results are compared with the experimental data and the calculated results obtained by two kinds of simplified calculation methods in the previous work. The numerical calculated results allow for the successful simulation of ship generated waves especially wave patterns which are impossible to obtain exactly from other estimation methods.

Due to the uncertainty and lack of continuity of routine dry docking and repair work increasing numbers of ship repair yards are looking for higher value and longer duration conversion projects. However many successful ship repair yards are finding it difficult to meet the contractual obligations of ship conversion and make a proft resulting in financial loss and damaged reputation. The complexity of ship conversion is highlighted and various commercial engineering and organisational aspects required for successful tendering and project planning design development and production managing of higher value ship conversion projects are discussed.

Current market trends indicate the importance of ship conversion work to Tyne ship repair yards - yard facilities are reviewed and examples of typical contracts discussed including - bulk carrier (PHILLIP L.D.) to drill ship (DALKEITH); side trawler (CONQUEST) to lengthened refrigerated vessel; supply vessel (SHETLAND SHORE) to rapid intervention rescue ship; anchor handling tug (GREY TITAN) to fire fighting ship; propulsion machinery modifications from marine diesel to heavy fuel IF30 systems.

Contents comprise of chapters arranged within two parts. Part 1, Outlines of Construction, contains the following chapters: The structure of the ship, Longitudinal strength, Principal systems of framing, Welded hull structures, Analysis of ship failure, Types of cargo ships and The problem of ship 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.

First a look is taken at why it is necessary to achieve the environmental friendly ship i.e. the Green Ship and some facts and figures are given. Next consideration is given to what the Green Ship actually is covering design aspects and operational aspects (on board management). After this future developments are dealt with addressing design developments and operational aspects. Lastly the profitability of the Green Ship is looked into covering incentives decentives costs and profits.

The subjects of the book are grouped to present a clear picture of the ship's operation. The bridge with its navigational instruments and communications, being the control centre of the ship, is dealt with first. Secondly come the engines and boiler rooms including auxiliary machinery and propellers. Deck gear such as derricks, winches and anchors come next, then ventilation and refrigeration. Finally there are safety measures.

An attempt is made to investigate factors in and their effects on the total loss risk of a ship accident i.e. on the (conditional) probability that a ship accident (having occurred) will lead to the total loss of the ship. A look is taken at a ship total loss propensity model followed by data. Next the estimation results are considered. After this incremental loss risk estimates are addressed. Lastly policy implications are outlined.

In the early design stages of ship hulls computer-based methods are used to check improve and compare multiple design alternatives. In the field of fluid dynamics increasing ship speeds place emphasis on the reduction of resistance. Codes based on potential flow theory are used to estimate and analyse the flow around the ship's hull and to determine the wave-induced resistance. The distribution of panels on the hull has a significant impact on the accuracy of the overall power prediction. Creating the panels on the hull surface especially for modern hull forms is a resource intensive non- or semi-automated task requiring a profound experience-based knowledge. The time needed for the manual definition of the mesh is high. No methods are known at present for automatically creating panel discretisations of ship hull forms. Mesh generation methods for potential flow calculations require appropriate descriptions of the ship hull surface. The IGES standard is a widely used format in the shipbuilding industry for the exchanges of ship hull forms. Methods are presented here to prepare ship hull form descriptions based on IGES files which are later used for potential flow calculations. Two major problems are solved: topology recovery and knuckle detection.

The use of VR (virtual reality) technology for planning ship repair operations is discussed. The creation of a VR-based environment is described. This allows the virtual execution of critical operations such as ship docking ship positioning verification and transfer of equipment and components on the ship. This virtual docking environment enables the user to verify design aspects of ship repair operations from an ergonomic perspective to place the ship on the shipyard dock as well as to evaluate alternative ways of positioning control the cranes and obtain critical quantitative information about the executed process. The simulation functions of the VR application and the capability of the system to deal with complex shipyard operations are presented and discussed.

A short history of Discovery and the Antarctic expedition of 1901 to 1904.

The ship dynamic stability criteria in the IMO Interim Standards for Ship Manoeuvrability - IMO Assembly resolution A.751(18) - are looked at. Course-keeping ability estimation for several ships is compared based on calculating both zig-zag and spiral manoeuvres. The spiral test gives a direct estimation of ship straight-line stability whereas the zig-zag test may give only an indirect assessment of this quality. The examples provided show the importance of including spiral tests in the procedure of ship manoevrability estimation.
