MARINE PROPULSION TECHNOLOGY both in-line and vee layouts, maxi- mum power rating currently offered by the design is 3,200 bhp.

The Daventry plant continues to make a key contribution to the development of Cummins'

Quantum system of compact machinery for the marine as well as industrial and stationary power markets. This is expressed in two prospective additions to the range, the QSK45 and QSK60 types, which are due to be introduced in 1998. While the existing K38/K50 models span the 800 to 1,800-bhp band, the new designs will cater to applications between 1,200 and 2,600-bhp unit output.

Sulzer population

The assimilation of New Sulzer

Diesel into Wartsila NSD has added a two-stroke dimension to the Finnish-owned group, bring- ing with it an approximate 35 per- cent share of the newbuilding, low-speed propulsion market and the long-term business scope sig- nified by the near 2,000 RTA engines ordered to date.

Since its introduction in 1981, the RTA series has been continual- ly updated to meet market needs and to reflect advances in technol- ogy.

The current installation of super wide-bore, 960-mm RTA96C diesels in post-Panamax contain- erships and the recent introduc- tion of more compact versions of the RTA-U series for tankers, bulkers, boxships and other ves- sels testifies to the market-led product development policy. This year's surge of orders for the

RTA84T type, unveiled in 1991 as an optimized unit for VLCCs, again vindicates the forward-look- ing design approach.

By the end of April 1997, refer- ences for the RTA range, encom- passing 10 bore sizes from 380 to 960 mm, and a power spectrum from 2,000 to nearly 90,000 bhp, had passed 39 million bhp.

Marine propulsion installations reportedly account for more than 38 million bhp.

Booked for eight post-Panamax linehaul newbuildings to date, and conceived for vessels as large as the 8,000-TEU designs now under discussion, the Sulzer RTA96C accommodates speeds of up to 24 to 25 knots at the top end of the capacity band, through an output of 7,470 bhp per cylinder. It incor- porates service experience with the RTA84C, the market leader in the large boxship sector with ref-

September, 1997 erences totaling 8 million bhp.

An enhancement to the range this year has been the introduction of shorter, lighter versions of the

RTA2U series, aimed at reducing non-earning space in a ship's hull and cutting engine manufacturing costs as well as easing installation at the shipbuilding stage. The long-legged U-types offer a stroke- to-bore ratio of about 3.5, exceeded in the Sulzer stable only by the 4.0 of the T models.

While Wartsila's preeminent market position in the medium- speed category and the acknowl- edged need to rationalize combined resources has major implications for the Sulzer four-stroke family, new business has boosted the sales tally for the Swiss-developed

ZA40S to 4 million bhp.
