U.S. Report Gulf Craft Delivers World's Largest Crew/Supply Vessel Touted as the world's largest Crew/Supply Vessel, in late May Gulf Craft Inc. delivered M/V Granville C. McCall, to Seacor Marine, Inc. The vessel is powered by five Cummins KTA-50-M2 diesel engines rated at 1,800 bhp @ 1,900 rpm, each coupled with a Twin Disc, model MG- 6848,2.93:1 reduction ratio gear. Each engine turns a four blade Teinbridge 54 x 54-in. Nibral propeller providing a light ship speed of 25 knots and fully loaded speed of 20 knots. The vessel also features a Thrustmaster 400 hp azimuthing thruster, powered by a Cummins N-14-M diesel engine. Twin 99KW Cummins 6BT5.9-G2 generators supply electrical power for the vessel's services and a Cummins 6CT8.3 diesel engine powers the Leroi WE 150 IIM - 80 PSI bulk compressor. The Granville C. McCall measures 190 x 35-ft. (57.9 x 10.6-m) and can carry 46,000 gallons of fuel, 82,000 gallons of drill/potable water, dry bulk capacity of 3,000 cu. ft., 2,500 gallons of ship's water, 600 gallons of main engine lube oil, 125 gallons of gear lube oil, 90 gallons of hydraulic oil, 6,000 gallons of gray water holding and waste oil capacity of 180 gallons. Aft deck space measures 112 x 28 ft. (34.1 x 8.5 m) providing 3,136 sq. ft. of loading area and deck cargo capacity of 400 long tons. It is capable of discharging drill water at 700 gpm @ 160 ft., discharging fuel oil at 350 gpm @ 130 ft. and dry bulk at 780 cu. ft./hr. @ 80 psi. In addition to servicing offshore facilities, it has fire fighting capabili- ties to pump 900 gpm via the stern fire moni- tor and 2,650 gpm via the main fire monitor. Circle 88 on Reader Service Card www.maritimereporterinfo.com Cascade General Completes Columbia Upgrades The 418 ft. ferry M.V. Columbia, owned by the State of Alaska, returned to service on the Bellingham-Skagway run after a winter layover at Cascade General. The 30-year-old ship emerged from the Portland Shipyard with a re-designed restaurant and cafeteria, re-furbished car-deck doors, reno- vated solarium, and with a laundry convey- or/elevator installed above the car deck. On the car deck, inspection of the port and starboard side doors revealed significant wear. A total of 16 dog rods, 10 pneumatic cylin- ders, plus hoses and seals were replaced. The hydraulic system on the stern door was also overhauled. A new linen-storage area was fabricated and suspended above the car deck forward. It is serviced by a conveyor from below and an elevator up to the main deck. The project also included a dry-docking for inspection of rud- ders, C.P. propellers, stern shafts and bowthruster. All sea chests and valves were checked and the hull water-blasted. The M.V. Columbia is one of nine ships in the Alaska Marine Highway fleet, all of which have vis- ited the Portland Shipyard in recent years. Circle 32 on Reader Service Card www.maritimereporterinfo.com United Defense Completes Acquisition of USMR United Defense Industries completed its acqui- sition of United States Marine Repair (USMR), for $316 million to expand its services for the U.S. Navy. United Defense financed the acquisi- tion by amending its existing credit facility to borrow an additional $300 million, and using cash on hand for the balance. Bollinger Proceeds on 8-Boat Fleet Modernization Bollinger Shipyards, Inc. earlier completed the conversion of the Crescent Towing tug, Florida, from a single engine to a 4,000-hp, twin-engine boat. The vessel is significant, as it is the first of eight Crescent Towing 105-ft. (32-m) sister ships to undergo the same major conversion at Bollinger's Algiers (New Orleans) repair and conversion shipyard. Florida now features two Caterpillar 3512B engines coupled to Reintjes WAF 673 reduction gears driving 83-in. Bollinger stainless steel propellers. They were installed in 84-in.. type 37 kort nozzles with stainless steel inner rings and leading and trail- ing edges. It has a 45 degree rudder angle for better maneuverability and its new power pack- age is designed to generate 100,000 lbs. or 50 tons of bollard pull. The boat's stern was also modified to accommodate the new propulsion system. Bollinger also reconstructed the Florida's wheelhouse with low profile stacks for maxi- mum visibility and installed new radars, GPS, depth sounders, hailers, VHF radios, fax machines, sound powered telephones, fuel emer- gency shut off systems, and remote control start and stops for the main engines. Smart Pneumatic Level Sensor with Generic 420mA Output The Bubbler is an electro-pneumatic level trans- mitter that allows remote level measurement using a 4-20mA analog output. The lack of air pressure poses no operational problems, due to an auto- matic one-way valve which closes as soon as the pressure drops below 1 bar, this prevents back flow in the bubbling line towards the transmitter. Over pressure is also protected against by an automatic one-way valve. • It's the size of a grapefruit • Explosion proof housing • Accuracy .3% full scale • Automatic over-pressure valve • Automatic stop valve for air failure • Automatic cleaning of bubbling line • Connection for pressurized tanks • 2 pair 24 VDC and 4-20mA cable • Top or side mount Many Options ELECTRONIC MARINE SYSTEMS, INC. 800 Femdale Place Rahway, NJ 07065 Call today for more information! 732.382.4344 732.388.5111 fax emsmarcon@aol.com e-mail http://www.emsmarcon.com Circle 224 on Reader Service Card www.maritimereporterinfo.com August, 2002 31
