Wartsila Puts More Sulzer RTA84T's On Large Tankers

For the year 2000, Wartsila Corpora- tion reports that 24 Sulzer RTA84T low- speed diesel engines with an aggregate power output of 713.4 MW (970,800 bhp) have been ordered for installation in very large tankers contracted at ship- yards in China, Japan and South Korea.

The engines will all be built by licensees of Wartsila in Japan and Korea.

Altogether there are now 78 Sulzer

RTA84T engines (including the -B and -

D versions) delivered or on order, with a combined output of 2,171.9 MW (2.95 million bhp).

Ten 305,000 dwt oil tankers recently contracted in China and South Korea by

National Iranian Tanker Co (MTC) will each be propelled by a seven-cylinder

Sulzer RTA84T-B low-speed diesel engine. The engines will have a maxi- mum continuous output of 27,160 kW (36,960 bhp) at 74 rpm, and give the ships a service speed of 15.5 knots.

Five of these VLCCs will be built at

Dalian New Shipyard, China, with

FGH And Ocean Rig Sign

Cooperation Agreement

Friede Goldman Halter (FGH) and

Ocean Rig have signed a cooperation agreement related to the completion and delivery of Ocean Rig's Bingo 9000-1 and Bingo 9000-2 offshore drilling rigs, which are currently being outfitted and Friede Goldman Off- shore's Pascagoula, Miss, shipyard.

The agreement results from a joint effort of Friede Goldman and Ocean

Rig to develop an acceptable plan and schedule for the completion and deliv- ery of the two fifth-generation rigs, and marks a significant step as the two rigs near completion.

This decision establishes new deliv- ery dates for the rigs, with a delivery date for Bingo 9000-1 set for March 2001, followed by Bingo 9000-2 on

June 1,2001.

Also outlined in the agreement is a specific incentive plan geared toward the completion of Bingo 9000-2.

According to terms outlined in this plan, Ocean Rig will pay an incentive bonus of up to a total of $5 million to

Friede Goldman as Friede Goldman meets certain pre-determined progress targets at the end of each calendar month between now and April 15, 2001. delivery between December 2001 and

December 2002. The other five will be built by Hyundai Heavy Industries Co.

Ltd. at Ulsan, South Korea, with their delivery due during 2002.

Eight VLCCs and ULCCs for Hellespont

Hellespont has contracted the first

ULCCs to be ordered for many years.

Hellespont recently placed orders for a total of four 442,500 dwt ULCCs at

Daewoo Heavy Industries Ltd, as well as four 310,000 dwt VLCCs at Samsung

Heavy Industries Co Ltd, both shipyards being in Korea.

The four ULCCs will each have a

Sulzer 9RTA84T-D engine of 36,900 kW (50,220 bhp) MCR output to obtain a service speed of 16.5 knots. The four

VLCCs will each be powered by a Sulz- er 8RTA84T-D engine of 32,800 kW (44,640 bhp) MCR output, for a service speed of 17 knots. In addition, the

ULCCs will each be equipped with three

Wartsila 9L20 auxiliary engines each of 1,530 kW output. The VLCCs will each have three 1,360 kW Wartsila 8L20 aux- iliary engines. These auxiliary engines will be manufactured at Wartsila's Vaasa factory in Finland. Other transactions include a 280,000 dwt VLCC at

Ishikawajima Harima Heavy Industries

Co Ltd (IHI) for Shinwa Kaiun, which will be powered by a Sulzer 7RTA84T engine of 27,160 kW (36,960 bhp) out- put. The ship is due for delivery in

December 2001.

Two 260,000 dwt tankers contracted by Formosa Plastics at IHI will each be equipped with a Sulzer 7RTA84T engine of 27,160 kW (36,960 bhp) output.

NYK Line ordered two 300,000 dwt

VLCCs at NKK Corp., which will each be powered by a Sulzer 7RTA84T engine of 27,160 kW (36,960 kW).

The ships are both due for delivery in 2002. A single 300,000 dwt VLCC has also been contracted by lino Kaiun at

IHI that will be equipped with a Sulzer 7RTA84T engine.

All six RTA84T engines ordered by

Japanese shipyards will be built under license from Wartsila Corp. by Diesel

United Ltd. The Sulzer RTA84T low- speed two-stroke diesel engine is specif- ically tailored for the propulsion needs of large tankers. It runs at low speeds (54 - 76 rpm) to match the optimum pro- peller speeds of such large ships.

As part-load fuel economy is impor- tant in ships which might have long peri- ods of 'slow-steaming,' the RTA84T uses flexible engine setting through vari- able exhaust valve closing (VEC), load- dependent cylinder liner cooling, and variable fuel injection timing (VIT).

These features contribute to the

RTA84T being the most economical propulsion engine for large tankers. It is manufactured in two versions, the

RTA84T-B and the RTA84T-D with a higher power output. Available with five to nine cylinders, the RTA84T covers a power range of 19,400 to 36,900 kW.
