English United Baltic Corporation's new RO/RO vessel will be equipped with Wartsila Diesel's Vasa 46-type main engines. The 13,000-dwt vessel, under construction at Hyundai Heavy Industries' shipyard in Ulsan, Korea, will have a father-and-son main engine installation consisting of one six-cylinder and one nine-cylinder Vasa 46 engine. The total output of the machinery is 13,600 kw.

The new vessel, which is bigger than any of UBC's existing ships, will be delivered in July 1989 and is scheduled for traffic between the U.K. and Finland. The vessel is icestrengthened to 1A Super standards and the advanced propulsion machinery allows optimized operation regardless of route and output need. The main engines will be manufactured at Wartsila Diesel's new production facilities in Turku, Finland, and they will be delivered to the shipyard by the end of the year. The Wartsila Vasa 46 selected for the new UBC vessel is an innovative medium-speed heavy fuel engine designed for maximum operational reliability. The Vasa 46 was launched in June last year and has awakened great interest in the market. The most significant design features of the Vasa 46 are the thick-pad bearing technology for reduced bearing loads, the SwirlEx charging system for high efficiency, and Twin Injection, the double injection system for a high rate of combustion and low fuel consumption. The anti-shake technology of the Vasa 46 includes rigid engine structure, full balancing and resilient mounting.

The first Vasa 46 engine will be delivered this month to the J.J. Sietas shipyard in Hamburg, where it will be installed as the main engine for the German Schiffahrtsgesellschaft Odin KG's new RO/RO vessel.

The Vasa 46 is offered in four-, six-, eight- and nine-cylinder in-line versions and in 12-, 16-, and 18- cylinder V-versions. The output range of the engine is 3,600-16,300 kw and the speed range 450-514 rpm.
