Welding information is required through the entire shipbuilding process from the design stage to the final erection stage. This paper develops a welding information system to provide the necessary information for each stage of shipbuilding in an easy and quick way. The properties of the welding information used at each shipbuilding stage and the information flow were analysed systematically. Welding information from classification society rules practices and standards of shipyards were all integrated into the object-oriented information model. A database system was combined with the information model.

A summary of the creation of the company NorthLink Orkney and Shetland Ferries Ltd which will from October 2002 operate the ro-ro ferry services between the Scottish mainland and the Orkney and Shetland Islands. The new NorthLink services will provide three new ships shorter crossing times more frequent crossings enhanced on-board facilities and lower fares. The operating deficit subsidy was tendered under EC state Aid rules and KPMG's innovative approach and vessel funding is discussed.

The book examines changes and developments relating to offshore racing yachts, including design, construction, accommodation, sails, rigging and equipment. It is international in scope, pointing out the best in offshore practice wherever it is found in the world. Practices such as windward sailing, offshore tactics, navigation are given their own chapters. Types, classes and rating are also covered. Special chapters on multi-hulls offshore and very small yachts examine their possibilities and limitations.

Classification rules are continually being developed to specifically address naval platforms and the opportunities offered to navies and suppliers by a different approach to standards and specifications. An approach to defining an appropriate standards policy with implementation throughout the platform life cycle is outlined to achieve the benefit of using established practices for verifying compliant with the requirements and thereby reducing project risk. The opportunities for change could permit naval resources to be more effectively deployed relieving navy specialists from procurement detail.

The prototype of "Regulation Auto-Check System" has been made experimentally to use the computer to check Classification Society regulations automatically. The system has been written using LISP. The frame theory was used to create the knowledge database and the three simple inference rules were used. The system has the management facility of the variables explanation facility concerning the checking process and the maintenance module for the knowledge database.

A broad overview of UK developments in marine engineering as detailed in recent IMarE Transactions. Areas of interest include Rolls Royce's Spey gas turbine engines as in HMS Grey Goose electric transmission for ship propulsion systems for the refit of the QE2 the Carnival Cruise Liner Fantasy and the Royal Navy Type 23 Frigate; machinery (remote / automatic) control of ships' propulsion systems and bridge control systems; air independent power systems for submarines Stirling Cycle engines as in the submarine Saga and fuel cells; environmental legislation and particularly new MARPOL Regulations and IMO rules.

The requirements of the International Association of Classification Societies (IACS) ABS and DnV in terms of residual strength following ship damage are compared. A case study involving a 70000 dwt bulk carrier is presented in which the determined residual strength factors and reliability indexes are compared. The IACS requirements are shown to be the strictest.

The book aims to bridge the gap between the theory and the practice of sailing. Chapters are as follows: Yachts and rating formulas (including C./R. Rule, C.C.A. Rule, R.O.R.C. Rule), Aerodynamics of the sail (aerodynamic forces, sail shape and interaction, centre of effort), The motion of a yacht (hydrodynamic resistance, yacht performance, stability and balance) and Wind and water (wind and waves, currents and tides).

This book on shipbuilding using iron and steel contains chapters on practical considerations of the strength of iron ships; keels, keelsons and garboard-strakes; stems; stern posts; transverse and longitudinal systems of framing; bracket-plate system of framing; deck framing and pillaring; deck stringers and plating; outside plating; bulkheads; topsides; rudders; iron masts; steel plates for shipbuilding; rivets and rivet-work; on testing iron and steel; Lloyd's and the Liverpool rules for iron shipbuilding; systems of work; and armour plating.

Anchoring systems principles and practices are described with reference to classification society rules. Data and descriptions of anchoring failures are discussed and main failure categories identified as lost anchor and cable lost anchor and broken cable lost anchor deformed anchor shank. The importance of correct operational procedures during anchoring was examined in practical tests with particular emphasis on speed over the ground and windlass control.

This introductory paper draws some basic comparisons between ocean wind and subsea power projects specifically how much space an ocean power plant would use and how this compares to present offshore wind farms. A hypothetical example of an ocean power station of 50 to 100 megawatts capacity was selected for this discussion. This paper identifies the principal parameters influencing the lay out of such a power facility. A case example is given to illustrate what may be some first order rules of thumb in ocean energy space utilization.

The review presented covers bilge and ballast pumping and piping arrangements for chemical and oil tanker systems liquified gas carriers and factory process ship systems. Rules published by the Classification Societies and the recommended codes of the Intergovernmental Maritime Consulative Organisation (IMCO) are considered. The burning of gaseous fuels gas supply and piping in machinery spaces dual burners factory process applications pipe systems boiler arrangements and flame failure are discussed. Venting flaring and incineration of waste gases venting to atmosphere vent types flame screens and the Coanda effect etc are described. Ventilation of manned spaces effective temperature standby fan capacity and emergency exits are outlined.

The structural design of high-speed vessels is examined particularly for those vessels covered by the International Code of Safety for High-Speed Craft (IMO 1995). These include monohulls catamarans air-cushion catamarans and other multi-hulled craft. Statistics are given on vessel types and parameters. Classification society rules and other regulatory aspects are presented. The environmental conditions and operational limits are explained. Aspects which are specific to loads on high-speed vessels from the structural design point of view are tackled. Structural response and strength are examined. Fluid-structure interaction is reviewed. Design considerations for production are described and design procedures and uncertainties are discussed. Finally conclusions and recommendations are presented.

This book begins with a brief history of oil and its transport, then goes on to discuss modern oil transportation, technical data on tankers, rules, economics, the current freight crisis, reaction to the crisis, pollution, response to oil spills, compensation for damage, tanker personnel and other issues such as piracy, war, fraud and stowaways.

Articles in this book cover the reliability of marine propulsion and steering systems, compensation for oil pollution damage from ships, management of risk, what is seaworthy vessel?, the regulatory framework for the carriage of bulk and packaged chemicals by ships, insuring oil cargo in the London market, and ship classification rules and international conventions - their relevance to design.

An outline of the evolution of fast craft structures which in the past has taken experience from the aircraft industry. More recently fast craft structures materials and designs have been designed under more perscribed rules. The current status in structural design and structural development is discussed with the need for the structural design and analysis falling outside current rule limitations.

This project provides the structural design process of the hulls for a sailing trimaran in accordance to the measurement rules of the Offshore Racing Multihull Association. A discussion of a suitable design approach is included, drawing information from a broader engineering field. The performance characteristics of multihulls and trimarans are discussed, as are the differences of different construction materials and topologies, which are compared with respect to the factors that influence the suitability for a high performance application.
