Cargo space is divided by two lon- gitudinal bulkheads and five trans- verse bulkheads into seven center tanks, four wing tanks on each side, and two slop tanks on the sloped double bottom that is arranged for easy stripping and cleaning and easy repair of tank coatings. Two of the wing tanks on each side and the double bottom tanks are intended for segregated ballast water according to the requirements of IMO's Marine Pollution Conven- tion (MARPOL) of 1973. The re- quirements of the 1978 TSPP are also observed, and the vessel con- forms to the IMO requirements on minimum ballast draft, trim, pro- peller immersion, and on the protec- tive location of the segregated bal- last tanks. Special coatings in all center tanks (85,600 cubic meters total) allow the loading of "white" prod- ucts such as jet fuel, kerosene, gaso- line, diesel oil, naphtha, and clean concentrate. At the same time, crude oil can be loading in the uncoated side tanks with a total capacity of 35,500 cubic meters. The cargo-handling system allows discharge of cargo in about 17 hours. Piping and pumping arrangements permit four parcels to be loaded or discharged simultaneously. Differ- ent grades of cargo are always segre- gated by two valves.

Two 2,000 cubic meters per hour ballast pumps are in- stalled. Central control equipment is pro- vided for the cargo oil pumps, bal- last pumps, deck machinery, etc. Cargo control stations are arranged on the upper deck in the accommo- dations space, allowing remote con- trol of cargo/ballast valves, cargo level monitoring, temperature, etc. NORD BALTIC Major Suppliers Main engine KHIC/B&W Propeller Kobe Steel Steering gear Kawasaki Auxiliary engines . .

The vessel is registered for 2,500 passengers and can pro- vide cabin accommodations for al- most that number. She has a capac- ity for 600 private cars or 62 trail- ers. The Olympia has an overall length of 580.7 feet and beam of 93.2 feet. Main propulsion is provided by four Wartsila/Pielstick 12 PC2-6V engines with a total output of 31,280 bhp, giving a service speed of 22 knots. Auxiliary machinery com- prises three Wartsila 6R32 diesels with a total output of 8,345 bhp. The ferry is operating on Viking Line's Helsinki-Stockholm route. This is the second big ferry deliv- ered by Wartsila's Shipbuilding Di- vision this year. The Turku yard also has under construction a 24,000-grt passenger-car ferry for A/S Jahre Line of Norway. The 12-deck Olympia is fitted with two stern ramps, fore gate with driving ramp, bulbous bow, two pro- pellers, two rudders, two bow thrusters, and fin stabilizers. Total lane length for private cars is 2,850 meters or 1,120 meters for trailers. As a rule, passengers are accom- modated in double cabins with berths at deck level. The cabins were prefabricated by the Wartsila Piikkio Works and are fitted with (continued) Maritime Reporter/Engineering News
