Shallow Draft Vessel Review (continued from page 15) CREW/SUPPLY VESSEL 'C/RAIDER' C/Raider Swiftships, Inc. of Morgan City, La., recently delivered the crew,/ supply boat C/Raider to CO-MAR Offshore Corporation, also of Morgan City. The vessel is the first in the CO-MAR fleet to be fitted with a ZF 2Vz:l reduction gear. Her MTU engines combined with the ZF gears allow the craft to use larger propellers. This re- sults in the vessel being able to transport heavier loads at higher speeds. A twin-screw vessel, the C/ Raider has a propulsion package consisting of two MTU 12V331 engines and ZF gears. A Delco 30-kw generator is driven by two Detroit Diesel 3-71 engines. On sea trials the boat attained speeds up to 25 knots. Having passed U.S. Coast Guard inspection, the C/Raider is certified to carry 65 passen- gers, aviation fuel, and corro- sives. Accommodations are pro- vided for a five-man crew. With a cargo deck space 58 feet by 16 feet, the vessel's cargo capacity on deck is 110 long tons; below-deck capacity is 52 tons. Loaded draft is 6 feet. The tanks hold 3,740 gallons of fresh water, 13,350 gallons of drill water, 500 gallons of drinking water, and 4,000 gallons of fuel, giving the vessel an endurance of 40 hours. Columbian supplied the propel- lers, four-blade, 42-inch by 38- inch Crewboat Bronze models. Electronics were supplied and in- stalled by Bibbins & Rice. They include a Furuno radar, two ra- diotelephones, a Drake TRM-1 SSB radio, Drake MRF-55 VHF radio, Texas Instruments TI-9900 automatic Loran, an Impulse 600CV depth sounder, and Dan- forth C654C compass. C/Raider is equipped with life- saving gear, and has full fire- fighting capabilities, and air-con- ditioning and heating throughout.

Pow- ered by a matched pair of Cum- mins KT-2300-M diesels with a combined output of 1,400 bhp at 1,800 rpm, the pusher tug is the first newly constructed boat on the nation's inland waterways powered by the KT-2300-Ms. The tug is 70 feet long with a beam of 26 feet and draft of 5*/2 feet. The sturdy vessel has been designed to handle heavy traffic. Twin Disc 530 gears with a 6.06:1 reduction ratio transmit power to twin 72 by 60 inch, stainless steel Kahlenberg propellers. Two knees rising 8 feet above the deck are bolted to the ship's understruc- ture for added strength and sta- bility. A Racor 800B-5 recycle blend- ing system helps save fuel by centrifuging crankcase oil after changes and recirculating the 35 to 40 gallons into the fuel system. A pair of Cummins 40-kw, N-495- GS generator sets, one a standby unit, provide electric power for lights, winches, and radios. The steel-hulled pushboat is be- ing used in Archway's switching operations based at Reidy Ter- minal in St. Louis. To further insure against lost time due to maintenance work, a service agreement has been signed with the St. Louis Cummins marine distributor, Cummins Missouri, Inc., for parts and service re- quests on a priority basis.
