Reintjes Perform In Demand Applications

Reintjes is an acknowledged leader for gears for unusual applications on special- purpose ships, such as vessels for public authorities, workboats, lifeboats and fast ferries, for transmission of engine outputs from 25010,000 kW.

Based in Hamelin, Reintjes gears are found aboard many of the most advanced types of vessels being built today, notably

Australian-built fast ferries such as the

Austal-built Auto Express 86 for l\irkish shipping line IDO, and the InCat-built

InCat 96 super freight ferries of the type, dubbed Devil Cat and Bonanza Express.

Reintjes units were also selected for the impressive InCat 91-type vessel, an 800 ton fast catamaran ferry series, which measure 295 x 85 ft. (90 x 26 m), and incorporate four compact high-performance diesel engines developing 7,000 kW each, gener- ating speeds up to 40 knots. Each engine acts on a gear to propel a water jet. Speeds of 1,000 min-1 have to be reduced with minimal weight to 450 min-1 suitable for waterjets. Use of Reintjes gears can be found much closer to home, as the compa- ny's products were specified for 40 new

U.S.C.G. heavy weather rescue cruisers of type 47' MLB (motor life boats) from Tex- tron Marine & Land Systems. About half of these boats were delivered by the end of 1998, and the remainder is to be put into service this year. These rescue vessels are an entirely new development calling for the highest performance from installed sys- tems, particularly the propulsion plant.

The rescue cruisers incorporate two

Detroit 6V92 TA DDEC diesels, each devel- oping approx. 310 kW/rpm 2,100 min-1.

This output is transmitted via Reintjes gears of type WVS 234 UP with 1:2 reduc- tion driving two fixed-pitch propellers (28 x 36 x 4"), providing a max. speed of 25 knots. The vessels have an action radius of 200 nm at a cruising speed of 22 kn.

The order presented a formidable chal- lenge, as in the event of capsizing the res- cue cruisers have to right themselves with- in six seconds. This involves first of all guaranteeing full gear functions even upside down without oil leakage. When the boat capsizes, the engines automatically run idle and initially the gears remain engaged. If air is sucked in during this time, the drive shaft is disengaged for a short time, and after the boat has righted itself the gears automatically reengage.

The orders were handled via Reintjes

U.S. contracting partner, Karl Senner Inc., based in New Orleans. This company, which was founded in 1972 and has branches in Everett and New York, has been highly successful distributing and ser- vicing Reintjes products in the USA.

New Training Resource For

Engine Room Staff

A new guide dubbed Fuel and Lube

Oil Training Manual has been published by Kittiwake, specifically aimed at the protection of extremely expensive and vital generating plants. The publica- tion, produced in conjunction with

Wartsila NSD and Mobil Oil Co., takes the reader through a simple, thorough understanding of both fuels and lubri- cating oils used in modern engine plants. The manual is $40.

Commercial Breakthrough

For MAN B&W

Following its traditional policy of a safe, step-wise development of new technology, MAN B&W has taken the initiative towards a commercial product by demonstrating the concept in full scale in actual service namely, on the 37,500 dwt chemical carrier M/T Bow

Cecil.

Upon its delivery to the Norwegian owner Odfjell ASA from Kvaerner

Flor0 yard in Norway, the vessel's main engine was equipped with the IE sys- tems in parallel with the usual camshaft.

This conventional system allows for a quick change-over to the IE system - or vice versa within three hours.

During a recent sea trial, the ordinary camshaft system was used during the first operating period of the vessel. Aux- iliary systems onboard were tested and the electronic hardware systems and comprehensive relevant software will be fit to the engine this fall.
