Meanwhile the compact 396-type engines, running at 2,100 rpm for short-time outputs of up to 3,480 bhp, dominate the market for fast catamarans and dynamically-sup- ported craft. SKL Moteren- und

Systemtechnik AG of Magdeburg is another engine-builder exhibiting a longer-stroke version of an estab- lished design; in this case their VDS 29/24 AL-1, super ceding the VD 24/ 24 series. The agreement with

Krupp-MaK, which is noted above, is most likely to lead to further coop- eration in design and manufacture.

Maschinenbau Halberstadt

GmbH supplies a range of models up to the VD 42/48 AL-2 of8,200 hp from the 12-cylinder version, the only larger engine designed and built in the former DDR. Twin-geared in- line versions power a class of Baltic train ferries. Arrangements made for the part manufacture and as- semble of a number of MAN B&W 40/54 engines may lead to closer cooperation between the two com- panies. The principal business of gear-makers Renk Tacke is the sup- ply of reduction and combining trans- missions for ferries and Ro-Ro ves- sels powered by medium-speed en- gines; also generator power take- offs with and without speed com- pensating mechanisms.

The Augsburg factory specializes in the compact, lightweight and highly-rated gears for frigates and destroyers. Among recent unusual orders are those for the three gas turbine/water jet drives in the trans- atlantic record challenger Destriero,

September, 1992 and a transmission to provide con- centric opposite rotation from a large slow-speed diesel engine for the most powerful contra-rotating propeller.

This is for Mitsubishi, who will in- stall it in a VLCC.

The addition of an electronically- controlled slipping clutch system,

ADS, fitted to a reduction gearbox made by Eisenwerke Reintjes GmbH has overcome a major problem en- countered in fast craft propelled by high-speed diesel engines.

Maneuvering to enter or leave a berth in a confined harbor is a tricky operation. Such engines can seldom be set to run at speeds which allow a slow approach, and the procedure becomes one of rapid ahead-and- astern movements.

The Reintjes ADS system, when selected, controls the pressure ap- plied to the multi-plate clutches so that, for instance with the engine set to its comfortable idling speed, the propeller can be driven, both ahead and astern at speeds corre- sponding to a turn-down of as much as eight to one below the constant ratio of the gear mesh. Four Reintjes

WVS 2232 reverse-reduction gears fitted with ADS and each associated with a P2, 500 hp Paxman engine are fitted in the large series of fast patrol boats which Bollinger has been supplying the U.S. Navy.

Coast Guard Issues Interim

Double Hull Requirements

The Coast Guard is adopting stan- dards for double hulls on vessels carrying oil in bulk as cargo or cargo residue that are constructed or un- dergo a major conversion under con- tracts awarded on June 30, 1990 or later. The Coast Guard is also issu- ing standards for double hulls on vessels carrying oil in bulk as cargo or cargo residue that have been con- structed or have undergone a major conversion under earlier contracts.

OPA mandates that these vessels have double hulls according to a timetable commencing in 1995.

The action provides the maritime industry with interim standards to meet the double hull requirment.

The interim final rule is effective

Sept. 11, 1992. Comments should go to the Executive Secretary, Ma- rine Safety Council, (G-LRA/3406) (CGD 90-051), Coast Guard Head- quarters, 2100 Second St., SW,

The Bitterness of Low Quality Lasts Long After

The Sweetness of Low Price

Why lose money on costly down-time due to an inferior steering system when for a few more dollars you can have state-of-the-art equipment designed specifically for your vessel.

The NAVIGAT X gyrocompass: •Highest MTBF in the industry •Easily serviced •No heating/cooling required •Follow-up rate to 25 deg./sec. •Automatically switches to 24 VDC in case of power failure

The NAVIPILOT V autopilot: •LCD digital display •Choose gyro, magnetic or TMC input (Transmitting Magnetic Compass) •Easily installed on any sized vessel •Independent off-course alarm •Compact
