The designers of accommodation on ships like the designers of buildings rely heavily on experience and tradition. They have few opportunities to test spaces and fittings as prototypes in use before committing to final construction. They also have little opportunity to know the expectations of users - passengers and crew - and to be able to balance those expectations with the requirements of maintenance staff and ship owners or with engineering and physical environmental constraints. It is suggested that POE (post occupancy evaluation) methods developed for evaluating buildings in use could also be used to evaluate and inform the design of passenger and crew accommodation on ships. POE has been developed and used in architecture during the last 20 years. It is a technique that enables designers to optimise the expectations of all interested parties associated with the building. It is a process of negotiation which can be used to inform the fine-tuning or re-fit of an existing building and provides a sound database about users' expectations for the design of new buildings. It has been used on a wide range of building applications including courthouses retail stores scientific research laboratories banks

FMEA (failure mode and effect analysis) is a reliability evaluation technique used to analyse risks involving the failure modes of technical systems onboard ships. The application of FMEA to automation systems of existing ships is examined for example whether FMEA could be applied to improve the safety of an automation system such as IBS (integrated bridge system). Experience from recent FMEA projects conducted in Finland are examined. These show that the FMEA on an existing ship should be organised using the knowledge and experience of users and maintenance personnel as much as possible. If the system consists of many computer-based units or sub-systems connected to each other identifying the possible failure modes and their consequences is very demanding. IBS is a typical example of this. A 'top-down' method such as FTA (failure tree analysis) can be used to complement FMEA in such cases. Some proposals for a successful FMEA project are summarised using the practical experiences.

Advanced maritime communications can be used to improve the availability of ship systems primarily by decreasing the mean time to repair (MTTR). The MTTR includes several activities including finding the person for the job travel times obtaining tools performing the job and the delay in waiting for parts etc once the job has been started. Maintenance planning and execution as well as spares stocking and ordering can be supported by various computer-based packages which usually contain a monitoring system for the machinery running condition a fault diagnosis system a maintenance management system and a data communications system. A system has been developed which allows point-to-point multimedia teleconferencing and computer-to-computer interaction with global coverage and versions have been installed on board ships and used in a variety of applications of remote technical support and surveillance.

An attempt is made to explain how ships under the Australian White Ensign are operated and maintained. In this case 6 ships are looked at the youngest of these being fifteen years old and the oldest being nearly thirty. After some introductory information a look is taken at the history - past present and future. Next each of the 6 ships - one off types of ships (orphans) under the control of the Amphibious and Afloat Support System Program Office or AASSPO - are listed with brief information. This is followed by consideration of some differences between merchant and naval practices. Lastly the challenge of the AASSPO to manage the process of maintenance and sustainment of this aging group of ships is looked at.

An inertial measurement system called MOTAN is presented. Results from one of its full-scale installations are discussed. It has been shown that the MOTAN system offers a novel approach for determining ice-induced global loads on ships. The instrument consists of two parts: an instrument for measuring whole-ship motions and software for processing those motions to obtain global ice impact loads. A background of the MOTAN system is given together with model-scale and full-scale data to support its feasibility for determining global loads from transient ice impacts. The focus is on full-scale data acquired while the CCGS LOUIS S. ST-LAURENT rammed old ice floes in the high Arctic. MOTAN-derived global loads are presented for three representative events. Data show that ice impact forces can approach 17.3 MN when ships operate in heavy ice conditions.

A stochastic analysis method is described to predict long term wave induced global design loads for ships in random seas. The method is based on nonlinear wave induced load effects; specifically on the concept of an ensemble of nonlinear transfer functions where each transfer function is valid only for a certain range of wave heights. The proposed method constitutes a practical alternative to nonlinear time domain simulations. These so called (nonlinear) pseudo transfer functions were obtained using a nonlinear correction to account for three dimensional effects of the hull shape and the non-vertical sides of the ship’s ends as exemplified by local bow and stern flare.

The Naval Oceanographic Office survey ships hydrographic survey launches and field parties use an integrated navigation system. This provides ship’s position velocity time heading roll pitch and heave information to the various subsystems of NAVOCEANO’s fleet of survey ships and HSLs. The system combines the accuracies and reliability of GPS and a state-of-the-art INS to meet the real-time navigation requirements of all survey missions. The approach taken in developing this integrated system is discussed together with the equipment and processes involved and the potential sources of error. Detailed results of the testing are also presented to evaluate the performance of the system.

World wide there is increasing interest in using ships of opportunity (SOOs) to acquire oceanographic data. New technologies mean that data for a wide range of parameters can be reliably measured and the data sent ashore in real time for analysis and assimilation into models. Commercial ships running regular routes provide data well suited to the validation of models. As they run year round they provide unaliased obersvations of seasonal changes. The scale of the operation can vary from global transporters to short ferry crossings. The EU ferryBox project has established "ground rules" for the development of new ventures. These will help to assure data quality and assist data management. The EU project CarboOcean and operations sponsored by the IOC are establishing global coverage for measurements using SOOs. The route operated by NOC between Portsmouth and Bilbao since April 2002 has already provided valuable information on water flow from the Bay of Biscay into the English Channel a new method for assessing plankton production and clear evidence for inter-annual variation in the supply of nutrients fuelling plankton production.

In 1987 there were only a dozen SWATH (small waterplane area twin-hull) craft in the world. However word of their superior sea-keeping performance has spread rapidly and their number is therefore increasing accordingly. The US and Japan are the leaders in the development and practical application of the SWATH concept. The characteristics of existing SWATH craft and ships are reviewed from the standpoint of the stated sea-keeping objective. Hull form differences between four SWATH craft and ships including the Navy's SSP Kaimalino are analysed and interpreted. Important considerations for the early-stage design of a SWATH ship are discussed. Differences in the range of feasible hull form geometries for coastal areas and unrestricted ocean operations and for low-speed versus moderately high-speed applications are highlighted.

The builder must reconcile the need to produce a safe ship without incurring excessive cost and efficient ship without involving unreasonable risk. The relationship between shipbuilder and shipowner is discussed with the contribution each can make towards design, building and commissioning a safe and efficient ship. The conclusion is drawn that the progressive builder exhibits a responsible attitude to legislation and economics of operation and is not satisfied with concentrating only on minimum cost and the meeting of current legislation. Some problem areas are discussed in more detail; these include stability of small and large ships, ships with low manning, dangerous cargo carriers, fuel and related problems, the question of material quality, and of accidents to personnel.

With an increasing annual volume of cargo carried between Europe and the Far East a study is being carried out into the passage of a Northern Sea Route (NSR) with a considerably shortened sailing distance between Europe and the Far East compared with the route via the Suez Canal. Using a model nuclear-powered icebreaking container ship (which has an advantage over the conventional ships in respect of energy supply) and conventional NSR ships a study was conducted into the comparative advantage and disadvantage of the NSR against an existing ship sailing via the Suez Canal. The calculation formula is discussed.

Three dimensional time domain Green function satisfying linear free surface and body surface boundary condition is employed to analyze the wave making resistance and wave profile of displacement multi-hull ships. The wave profile induced by a moving time domain point source is compared with those by a Havelock source and satisfactory results are obtained. The panel method based on the time domain source distribution on the ship mean wetted hull surface is used to perform the wave making computations for mono-hull ship catamaran and trimaran. Reasonable results are also obtained. Using the numerical method the wave profile simulations of multi-hull ships in a given Froude number are shown in this paper
