FIRE/UTILITY VESSEL 'POINT T'

Halter Marine, Inc. of New Or- leans introduced a new line of fire/utility boats with the recent delivery of the 150-foot Point 'T' to Point Venture, Ltd. of Morgan

City, La. In addition to her 61,- 000-gallon liquid mud capacity, the new vessel carries three 6- inch, 2,400-gpm fire monitors ca- pable of pumping water as well as 1,720 gallons of foam.

The Point 'T, with overall di- mensions of 150 feet by 36 feet by 14 feet, is powered by two

GM Detroit Diesel 16V-149NA en- gines each developing 900 bhp at 1,800 rpm.

She has a cargo capacity of 275 long tons and has 2,200 square feet of cargo space on her aft deck. She can carry 78,560 gallons of fuel oil, 1,283 gallons of lube oil, 3,974 gallons of fresh water, 108,196 gallons of ballast water, and has a sanitary holding ca- pacity of 895 gallons.

Auxiliary machinery includes two GM 75-kw generators driven by two Detroit Diesel 6-71 en- gines, a Continental Electric gen- erator control panel, an Engine

Monitor monitoring system, two

Quincy D325 air compressors, and

Aurora fire, ballast, bilge, and fuel-transfer pumps. The vessel is fitted with a Bird-Johnson bow thruster driven by a GM diesel, and the engine room is protected by a fire alarm system and auto- matic COL. flooding system.

Living quarters include six cabins, 20 berths, and a fully equipped galley. Classed by the

American Bureau of Shipping A-l + AMS, Point T meets the re- quirements of USCG NVC 1-78 and USCG Subchapter I; carries a Panama Canal Admeasurement

Certificate; and is approved by the U.S. Public Health Service. fart-,

SURFACE-EFFECT BOAT 'RODOLF' fan. The widely spaced propellers make the craft highly maneuver- able at all speeds, both cushion- borne and hullborne.

As a result of the surface-effect vessel's unique design, the Rodolf is expected to improve significant- ly hydrographic and surveying technology through its high-speed capability and minimal wake. The boat rides on a cushion of air con- tained by catamaran style side hulls and flexible bow and stern skirts. At cruising speed the cen- ter portion of the hull is clear of the water, supported on the air cushion, thereby reducing re- sistance, providing higher speed, and improving ride and stability qualities.

Bell-Halter is a joint venture of Bell Aerospace Textron and

Halter Marine formed to design, construct, and market air-cush- ion craft for commercial service.

Rodolf

The Rodolf, a 48-foot surface- effect vessel built by Bell-Halter of New Orleans for the Portland (Oregon) District of the U.S.

Army Corps of Engineers, began service with a tour of the Gulf and Atlantic Coasts to demon- strate its operational and hydro- graphic surveying capabilities.

Two 350-bhp GM Detroit Diesel 8V-92N engines power twin four- bladed propellers, and a Detroit

Diesel 105-bhp 4-53N engine drives the 30-inch-diameter lift

TRAWLER 'STORM PETREL'

CREW/SUPPLY BOAT 'PORT ARTHUR'

Progressive Shipbuilders and

Fabricators, Inc. of Houma, La. has delivered the aluminum crew/' supply vessel Port Arthur to Port

Arthur, Inc., also of Houma. The 110-foot boat has a beam of 24 feet and depth of 10 feet 6 inches.

She is able to carry 63 passen- gers and a crew of five, as well as 47 long tons of deck cargo.

Normal service speed is 28 knots.

Main propulsion is provided by four GM Detroit Diesel 12V71 engines, each with an output of 445 bhp at 1,800 rpm, supplied by

George Engine Company. Twin

Disc supplied the four reduction gears, model MG 514, with 2y2:l ratio. Engine controls were sup- plied by WABCO.

Fuel capacity is more than 6,000 gallons, drill water 7,500 gallons, and potable water 800 gallons.

Navigation and communica- tions equipment, supplied through

Rhodes Electronics of Houma, in- clude Furuno FRS 36 radar, Sim- rad LC 123 Loran C, Konel 1022

SSB radio, and Raytheon DE 750

Fathometer. Two GM 'Delco die- sel generators provide electric power.

Storm Petrel

Another first for MARCO Se- attle was accomplished with the delivery of the fishing vessel

Storm Petrel to owner/skipper

George Fulton. She is a refrig- erated seawater, trawler/combi- nation boat, MARCO's first to be designed and engineered princi- pally as a trawler. The new ves- sel has an overall length of 123 feet, beam of 31 feet, and depth of 14 feet.

Propulsion power for the Storm

Petrel comes from a turbocharged and aftercooled Caterpillar D399-

TA diesel with a continuous rating of 1,125 bhp at 1,225 rpm, driving a 96-inch Coolidge stainless-steel propeller through

Reintjes reverse/reduction gears, providing a normal service speed of 12 knots. Auxiliary power is provided by one Caterpillar 3304N and two Cummins KT1150GC en- gines.

The vessel features a two-deck aluminum pilothouse above the raised deck. The bridge deck has a 360-degree field of vision, and contains an aft-facing hydraulic control console that includes trawl winch controls.

The new boat has a complete outfit of electronics and other navigational aids, including two radars, two sonars, Loran, and a variety of radio equipment (see accompanying supplier list).

Much attention was given to net- and fish-handling space and equipment aboard the vessel, com- bining such features as the re- frigerated seawater system, an eight-well configuration with a to- tal capacity of 8,800 cubic feet, an articulated stern ramp, and a combination of gear that includes the first pair of MARCO's new

WT-303 trawl winches and a re- movable four-drum stern gantry.

The new hydraulic ramp ar- rangement, which encloses the boat's stern when not in use, was developed by Mr. Fulton. MAR-Port Arthur 14 Maritime Reporter/Engineering News
