Driving the Containership

Market

While the VLCC market is help- ing to drive RTA84T sales, the con- tainership market continues to provide the engine builder with interesting prospects. It remains a strong market in terms of vol- ume, but perhaps more important- ly, it is a sector which continually challenges engine builders to devise advanced technological solutions. Larger, faster containe- ships require high output propul- sion engines, which must operate most reliably with the least time out of service (see related story in this month's "Investment in

Design" section, page 8).

The world's most powerful diesel engine — the Sulzer

RTA96C two-stroke marine engine with an output of 89,640 bhp — was recently successfully tested in

Aioi, Japan. The engine was designed and developed by

SHIPYARDS

The buoyant newbuilding mar- ket for VLCCs has brought increased order activiity for Sulzer

RTA84T engines. Wartsila NSD announced that orders for the year (to Oct. 1,1997) totaled 12 VLCCs, each powered by the 7RTA84T engine. The engines have a com- bined output of 443,520 bhp, and are for vessels under construction in Japan and Korea (see chart below).

The RTA84T low-speed two- stroke diesel engine is specifically designed for the propulsion needs of large tankers. It runs at low speeds (54 to 74 rpm) to match the optimum propeller speeds of these large ships. As part-load fuel economy is important in ships which might have long periods of slow-steaming, the concept of flex- ible engine setting is extended in the RTA84T to include variable exhaust valve closing (VEC), load- dependent cylinder liner cooling, and variable fuel injection timing.

Wartsila NSD two-stroke diesel engine center in Switzerland as a driving force for the new genera- tion of larger, faster container- ships. The engine is the first of four 12RTA96C types that were
