& NAME Annua would also be useful in relation to future fleet newbuild schemes.

Building on its experience in simula- tion work, Deltamarin has also unveiled a new product known as Total Safety and Risk Assessment (TSA), developed in conjunction with Royal Caribbean

International and Norwegian ferry spe- cialist Color Line. Drawing on both owners' experience from earlier, theoret- ical safety assessment schemes, criteria for the new technique was that it should be systematic and comprehensive, and should yield practical results in analyz- ing the ship and in determining the most cost-effective ways of improving safety and service reliability.

The collaborators took the view that if the safety assessment process were to be effective and efficient, the effort required to undertake the task and implement remedial action should be minimized. Accordingly, a working pro- cedure has been developed which can be repeated from one case to another. The new method sets out to identify all sin- gle mechanical or electrical failures or operational errors leading to a situation where the ship is incapable of fulfilling its mission.

The methodology is general and sys- tematic in appraising the overall safety of the ship, systems, spaces, and func- tions onboard. It is based on two gener- ic databases, which are used according to formal safety assessment principles (FSA). One introduces a model of the ship, describing all the essential services on board, and links functions, systems and subsystems to services. The other is an evaluation criteria database. A soft- ware application called the auditing guide assists the surveyors through the different phases and facilitates efficient management of documentation.

The classification society sector has shown serious interest in TSA. "To date, we have worked on four vessels utiliz- ing the TSA method successfully, but in the future we intend to use it as a design tool, so that it can be applied more widely and proactively, even as a sur- veying tool," observed the consultancy's business development director Markku

Kanerva.

In applying the methodology to new- build projects, the process starts with analysis of the arrangement of the ves- sel, including location of high-risk spaces and areas, system location and routing, through to system configura- tion.

It is felt that the major strides in tech- nology, vessel concepts, and size and complexity necessitate a proactive approach to safety issues. "New con- cepts should be thoroughly tested before application," argues Kanerva, who con- siders that modern simulation tech- niques and risk-based assessment meth- ods offer valuable opportunities for reflecting such structured analysis in a design before construction is initiated.

Effective simulation tools and comput- er-based safety assessment open up major new potential in achieving cost- effective safety improvements. As one element of the drive to use virtual-reali- ty techniques for modeling operational scenarios, Deltamarin has developed a passenger evacuation model in co-oper- ation with the University of Strathclyde.

Code-named Evi (evacuability index), it employs a virtual environment for enhanced effectiveness in evaluating evacuation performance of ship design.

Provision of the contract design and detail design for the forward half of the 72,000 gt newbuild cruise ship ordered at Litton Ingalls by American Classic

Voyages Co. (AMCV), Deltamarin is making an important technical services contribution to a seminal U.S. program.

The Finnish stamp on the milestone

Project America scheme, signifying a

U.S. return to large, ocean-going pas- sengership construction after a gap of 40 years, is also expressed in Elomatic's retention for the parallel design work on the aft half of the vessel. Litton Ingalls' teaming agreement with Kvaerner

Masa-Yards had already generated

Finnish input ranging from concept development and preliminary design to the latest production know-how.

Finnish shipbuilding's propensity for the most technically sophisticated and specialized forms of commercial vessel tonnage has given Deltamarin an impor- tant domestic platform from which to progressively develop business on the international stage.

The extension of its activities has been such that some 90-percent of invoiced sales last year were generated outside

Finland.

Fortum Tankers Built To Deltamarin Design

Deltamarin Ltd. is supplying the design for the tanker newbuildings for Fortum, a Nordic energy company, which are being built at Jinling Shipyard in China and at Estaleiros Navais de Viano do Castelo (ENVC) shipyard in Portugal. The project at Jinling is a product/chemical tanker with ice class 1 A Super which measures 556 x 78 ft. (169.5 x 23.8 m), with a deadweight of 25,000 tons and a speed of 16 knots. Total cargo tank volume is 28,000-cu.-m. The newbuilding at

ENVC is a chemical/product tanker with ice class 1 A Super which measures 459 x 71.2 ft. (140 x 21.7 m, with a deadweight of 14,000 tons and a speed 16 knots. Total cargo capacity for this ship is 16,000-cu.-m.
