Outboard profile drawing of the new MARCO spill recovery vessel.

Burrard Clean Operations Ltd. of Vancouver,

British Columbia, Canada, has contracted with

MARCO Pollution Control, one of the world's largest builders of oil spill recovery vessels and systems, for the construction of a new design 75-foot spill recovery boat. Additionally, in an unrelated project, MARCO announced the com- pletion of the lengthening of the RSW trawler

Golden Dawn.

The new TOR-75R Class vessel, which will be built at a Vancouver area yard under the super- vision of MARCO, will be of steel construction and feature a four-foot-wide version of MAR-

CO'S Filterbelt oil and debris recovery system.

The Filterbelt, which removes oil and debris from the water surface without taking the water aboard, recovers all types and grades of petro- leum products, from light distillates to heavy weathered crude.

Construction will begin immediately on the 75- by 22-1/2-foot vessel, with delivery sched- uled for the spring of 1991. When completed, the new TOR-75R will be capable of processing up to 10,000 gallons of oil/water mix per minute to recover up to 400 gallons of oil per minute.

The Seattle shipyard of MARCO completed the work on the RSW trawler Golden Dawn. The boat was lengthened by 27 feet and now has an overall length of 149 feet. The new midbody added a fishhold and increased carrying capac- ity to 12,270 cubic feet.

Other changes included an RSW System from

Cold Sea, MARCO fish unloading system, switchboard from Harris Electric and a new Cat- erpillar 3406 290-kw genset.

WHALE OF A WHEEL—Karl W. Kahlen- berg, president of Kahlenberg Bros., Inc., Two

Rivers, Wis., poses with huge propeller, the larg- est stainless steel casting in Waukesha Found- ry's 78-year history, before shipment to towboat customer. In designing the 102-inch wheel, Kah- lenberg had to first determine what the horse- power absorption would be on the propeller.

Blade Pressure loading was then calculated in terms of pounds per square inch, and then blade shape was determined by CAD. The propeller will absorb 2,150 hp at 267 shaft rpm, contin- uous.

Alaska Diesel Introduces

New Lugger Model Engine

Alaska Diesel Electric, Seattle, Wash., has introduced an all-new Lugger marine diesel designated the L6108A. The new inline six pro- duces 330 hp at 2,600 rpm and follows the same design criteria as the 460- and 600-hp Luggers. "We see a strong demand for a premium engine in this size range," ADE's vice president

Scott Kennedy said. "With its 436-cubic-inch displacement and a long list of heavy-duty fea- tures, it will appeal to fishermen who are uncomfortable with small bore, high-speed en- gines."

Touted features include replaceable cylinder liners, Bosch-type injection, liquid-cooled tur- bocharger, freshwater aftercooler, fuel-efficient four-cycle operation, VDO instrument panels and single side service.

For more information on the L6108A or any of the Lugger models from 61 to 600 hp,

Supply Corps, present the planned producer award to Alfa-Laval Separation, Inc. president

Claes Arnegren in recognition of the compa- ny's voluntary efforts to assist the Navy in its

Industrial Preparedness Program. The main ob- jective of the Preparedness Program, according to Lt. Allen-Cottrell, is to ensure that the sup- plier, in the event of conflict or war, is able to supply key parts in pre-specified quantities within a certain time frame. "We have over 90 percent availability of all parts at any given time," noted Mr. Arnegren.
