An optimum structural design system for double hull VLCC is developed based on the generalized slope deflection method and the Hooke & Jeeves direct search method for the DnV and Lloyd rules. Several minimum hull weight designs of double hull VLCC of 300000 DWT are performed using this system. The minimum weight design of longitudinal strength members transverse strength members transverse bulkhead members and cargo hold part is considered. The structural design system results are compared with existing ships and the automatic drawing of midship section is provided.

The oil and gas production industry has expressed an interest in being able to use FPSO (floating production storage and offloading) units as a development option in the deepwater areas of the US GOM OCS (Gulf of Mexico outer continental shelf). A workgroup was formed under the Offshore Operators Committee's Deepwater Subcommittee to help the MMS (Minerals Management Service) and USCG (US Coast Guard) review the existing regulations and body of standards specifications recommended practices and classification society rules and guides concerning the design and operation of FPSOs on the GOM OCS. The aim was also to identify gaps in the regulations and industry standards. A summary of the major findings of this workgroup is presented.

Attention is given to a study conducted by The Ship Stability Research Centre (SSRC) within the scope of various projects addressing the stability and survivability of cruise vessels. Relevant results deriving from numerical and physical model tests are presented pertaining to the application of current and future rules for passenger ships while highlighting the drawbacks and the need for the development of performance based assessment. After some introductory information a look is taken at intact stability criteria. Next damage stability and survivability are considered followed by large scale flooding.

The new MaK long-stroke engines are designed especially for operation on residual fuels from the oil refining process. They provide excellent prerequisites for safe operation on heavy fuel even with rising quality characteristics in the future - i.e. with declining quality. A look is taken at this generation of MaK engines which are simple easy to operate and non-adjustable. Next heavy fuel specification is considered. After this MaK rules for heavy fuel treatment are looked at.

Whether to maintain or replace equipment is discussed together with the benefits of technology. In conclusion five rules are listed that should be followed in order to avoid the pitfalls associated with poorly managed electrical maintenance. Graphs appear on the pages 09 and 10.

A hull form Baltic ice class IA Aframax tanker has been developed taking into consideration of powering performance in brash ice channels based on IA class rules. Speed performance of the ship hull form in normal seagoing has been validated through model tests in a towing tank. The hull form design developed in this work has demonstrated good speed performance in normal seagoing although the ship design is entitled to ice class IA

Some results are presented from a research programme devoted to the development of reliability procedures for the verification of the longitudinal strength of hull girders subject to bending loads. Both static and dynamic loads are considered and a stochastic model for loads as well as for strength characteristics is discussed. Results from reliability assessments of existing ships are provided to show the effects of certain choices made during the development of the model. The model is also used to define design rules to obtain pre-defined safety levels for new constructions. The results of a prototype application are presented.

In the paper aspects on the design and construction of a river passenger ship catamaran type made of composite materials is described. The main dimensions of the ship are - Length = 10.22m Breadth = 4.6m Draught = 0.45m. The hull is made of E-glass polyester having the mechanical characteristics: E=7000 MPa RT=95 MPa RB=130 MPa. Two outboard engines of 150 HP do the propulsion of the ship assuring a speed of 20 kn. The ship is designed and built according to Germanischer Lloyd 2004 Rules Special Craft; Yachts and Boats up to 24m.

The FKAB Environmental Ship Concept (FESC) Design is a study into designing global friendly ships for sea transportation. The aim has been to show that already today with existing technology it is possible to design ships based on sustainable technology with low emissions to air and sea with acceptable or good economic perofrmance. Another aim has been to show ship owners how to be proavtice in relation to future rules and regulation. The concept focus is wide and includes the whole life cycle of the ship.

With the world fleet ageing fast the problems of corrosion in ballast tanks and (bulk carrier) cargo holds are becoming more apparent. Classification societies are taking the initiative harmonising class rules and taking steps to inspect these areas more often and more thoroughly. Good coating specifications at newbuilding stage can significantly postpone the onset of corrosion. The quality of surface preparation achieved by different techniques is considered along with the coating types they are most frequently combined with.

Brittany Ferries Managing Director for UK and Ireland looks at the case for more stringent safety rules following the rolling of the car ferry Havelat in heavy seas while en route to Brittany. Discussons and proposals concerning ship design and crew training have been made but little attention paid to what owners operators are or believe they are doing. It is suggested that marine safety agencies - government departments and classification societies should act more responsibly and positively.

Contents comprise of the following sections: Rules for good ship husbandry, Cleanliness, Prevention of malpractice, Correct use and stowage of equipment, Preventive and corrective maintenance and Observance of safety precautions. Appendices contain specific information and suggested products for use.

Current safety and pollution prevention requirements for ships are explained and how the requirements are sometimes deemed too prescriptive and focusing insufficiently on perceived hazards. Some would like future requirements to be formulated on the basis of formal safety assessments. Firstly hazards are outlined. Next a regulatory strategy is suggested. The regulatory regime is detailed. It is explained that the present regulatory regime is the only practicable form of rules and regulations for shipbuilders and that this needs to be understood if considering its replacement with a regime based on formal safety assessment .
