board these rigs will be from 13,500 kw to 32,500 kw (18,200-43,900 hp).

Reliability and operational econo- my are most important in the selec- tion of engines for the new genera- tion of semisubmersibles. The ad- vanced technical features of the

Wartsila Vasa engines, including patented pressure lubrication of the piston skirt, a load-dependent tem- perature control system and a tur- bocharging system developed for good low-load performance, com- bined with a long operational expe- rience in the Arctic, make the Vasa engines an ideal choice for these rigs.

The Wartsila Vasa 32, with a bore of 320 mm and a stroke of 350 mm, is one of the most popular diesel engines within its output range at the moment. The output of the Vasa 32 is 1,480-6,750 kw (2,010-9,180 hp) in a speed range of 720-800 rpm.

The Vasa 32 is capable of burning fuel viscosities up to 700 cSt/50°C/ 700 sRI/100°F). The engine manu- facturer, Wartsila Diesel, is one of the world's leading suppliers of die- sel engines for marine and land- based installations.

Megasystems Introduces

Engine Cylinder Pressure

Monitoring System —Literature Available

Megasystems Inc., Boca Raton,

Fla., recently introduced a new en- gine cylinder pressure monitoring and alarm system, EPS/256, that is said to be versatile, compact and economical. The unit, which can be installed in a 19-inch rack, monitors peak cylinder pressures and alarms if the pressure is too high or not bal- anced throughout the engine. From one to 256 channels can be moni- tored; more than one engine can be monitored. The unit can operate from 0° to 70°C. The EPS/256 can be used in the field or in the labora- tory. The units utilize Megasystems' own combustion pressure sensors.

Wartsila-Normed Joint

Venture To Manufacture

Diesels In France

The French Chantiers du Nord et de la Mediterranee (Normed) and the Finnish Wartsila Group have recently founded a joint venture company for manufacture of Wart- sila Diesel Division's medium-speed heavy-fuel engines at Normed's La

Ciotat shipyard. The new company, called Wartsila Diesel Normed SA, will manufacture Wartsila Vasa- type engines for France and some other territories. The Wartsila-

Normed joint venture will launch a new generation of French-made heavy-fuel engines on the market.

Production at the factory has al- ready started and the first engines have been delivered. The joint ven- ture company also has a large num- ber of engines on order, among them six Wartsila Vasa 6R22 HF engines for the two wind cruisers ordered by

Circle Line of US at the ACH Le

Havre shipyard in France.

Wartsila Diesel Normed is the fifth Wartsila Diesel engine factory.

The other four production plants are located in Finland, Sweden and

Singapore. The new company will also be supported by the worldwide sales and service network of Wartsi- la Diesel.

Normed was founded in 1982 af- ter three shipyards, Chantiers de

France Dunkerque (FDK), Chan- tiers Navals de La Ciotat (CNC) and Constructions Navales et In- dustrielles de la Mediterranee, (CNIM) merged. The group has three shipyards: one on the North

Sea coast at Dunkirk and the others on the Mediterranean coast at La

Ciotat and La Seyne.

With Elliott White Gill thrusters, you can turn a vessel in its own length. Position it broadside. Negotiate congested docks and tight berths. Counteract strong cross-currents. Even provide main propulsion.

Without extending outside the hull lines of the vessel, reliable White Gill Units provide thrust that is completely variable throughout 360°, and is not diminished by ship motion. That's total control—with minimum hull resistance and without danger of fouling or damage by underwater obstructions— even in the shallowest water in which the vessel can operate.

Control systems range from a simple joystick (lever) to computerized dynamic positioning.

Hundreds of these easy to install units—original equipment and retrofits—are saving time and money on tankers, tugs, oil rig service vessels, barges, research ships, salvage vessels, cable ships, ferries and other vessels throughout the world.
