pump and a plate-type oil cooler team up to provide more effective cooling. Adjustable rear engine brackets make installation easier and anti-vibration mounts help re- duce noise. The 31 and 41 Series are a new generation of marine diesels for workboats, including three 4-cylin- der and two 6-cylinder direct-in- jected models, available in naturally aspirated (31 Series only), turbo- charged, and turbocharged and af- tercooled versions. Due to lower heat losses with direct injection, fuel consumption has been slashed by about 15 percent, without losing the exceptionally good acceleration and response. from poor quality heavy fuel to high quality hydrocarbon gases without any engine modification or loss of power. The Vasa GD is a multifuel engine well suited for a number of different installations: offshore power plants, pumping and com- pressor stations and fuel-off-the- well operation in the oil industry. Davy And McDermott Form Joint Company Davy Corporation and McDer- mott International have agreed to form a joint company for project management, design engineering, procurement, onshore and offshore construction management services for the oil and gas exploration and production industry in the U.K. sec- tor of the North Sea. The company will also undertake work in the U.K. for projects outside this sector. The new company, Davy McDer- mott Limited, will be owned 51 per- cent by Davy and 49 percent by McDermott. Annual sales of Davy and McDer- mott total around 2.5 billion. AT YOUR SERVICE WARTSILA DIESEL Circle 32 on Reader Service Card Finnish engine maker Wartsila Diesel has introduced the Wartsila Vasa 46, an innovative medium- speed, four-stroke heavy fuel engine designed for maximum operational reliability. The most significant de- sign features of the Vasa 46 are the thick-pad technology for reduced bearing loads, the new SwirlEx charging system for high efficiency at all loads and speeds and Twin Injection, the double injection sys- tem for a high rate of combustion and low fuel consumption. The anti- vibration technology of the Vasa 46 includes rigid engine structure, full balancing and resilient mounting. The output range of the engine is 3,600-16,300 kw (4,828-21,858 hp) at a speed range of 450-514 rpm. The first Vasa 46 installation will be aboard a multipurpose RO/RO vessel being built at the J.J. Sietas Shipyard in Hamburg. The vessel, scheduled for completion in Sep- tember 1988, will have a six-cylinder Vasa 46 as her main engine. In another installation, English United Baltic Corporation's new RO/RO vessel under construction at Hyundai Heavy Industries' Ulsan shipyard will be equipped with a "father-and-son" engine arrange- ment consisting of a six-cylinder and a nine-cylinder Vasa 46 main engine. Vasa 46 main engines will also be installed on two new passenger/car ferries under construction for Fin- nish-Swedish Silja Line. Another recent introduction from Wartsila is the Wartsila Vasa 22/26, a powerful medium-speed auxiliary engine. This engine is well-suited for power production in different types of vessels. Rigid design of the components combined with an op- timized combustion process guaran- tees reliable and economical opera- tion at all loads, even on the lowest grade heavy fuels. The Vasa 22/26 has a cylinder bore of 220 mm and a piston stroke of 260 mm. The out- put range is 54—3,000 kw at speeds ranging from 720 to 1,100 rpm. The latest achievement in the de- velopment of the Wartsila Diesel engine range is the Wartsila Vasa GD, a new gas diesel engine that can operate on a wide variety of fuels, July, 1988 A NEW LINE OF MARINE LUBRICANTS EXXMAR ® FOR TRUNK PISTON AND CROSSHEAD DIESEL ENGINES EXXMAR 12TP EXXMAR 24TP EXXMAR 30TP EXXMAR 4QTP EXXMAR XP EXXMAR XA EXXMAR X22 EXXMAR X60 EXXMAR X7Q EXXMAR X90 AND AIM EXTENSIVE LINE OF OTHER PRODUCTS TO COVER LUBRICATION REQUIREMENTS OF ALL SHIP MACHINERY AND THE SIGN OF SERVICE EXX PROGRAMMED ANALYSIS OF MARINE LUBRICANTS IN SERVICE A Superior Service To Assist The Ship's Engineer With Efficient Care And Maintenance of EXXON Lubricants in Service EXXON COMPANY, INTERNATIONAL Marketing Dept./Marine Sales 200 Park Avenue Florham Park, N.J. 07932-1002 Tele: (201) 765-4900 THE SIGN OF SERVICE Circle 237 on Reader Service Card 23
