Master Marine Responds To Change

In The Shipbuilding Market

With Vessel Conversions

Master Marine, Inc. of Bayou La

Batre, Ala., recently converted a 96- foot aluminum crewboat to a 149- passenger whale watch/excursion vessel for Barnstable Whale Watch

Tours Inc., Barnstable, Mass.

The vessel, named Spirit, was converted in just under eight weeks.

Work consisted of installation of three main engines and one genera- tor, with special spiral design Cowl mufflers from Canada, chosen be- cause of their compact size and ease of installation in the engine room.

Conversion work entailed fabrica- tion of a 35-foot extended deck- house with two bathrooms in the stern, full service snack bar, cush- ioned benches and tables. Interior finishing incorporated the use of fiberglass reinforced plastic pan- eling on the walls, which is very dur- able and will not rot and fade like wood paneling. Four sliding doors make way for easy passenger access.

Handrails with safety screens on the main deck and the topdeck make it safe for families to view the beauty of the ocean. A bow pulpit was con- structed for sighting of marine life.

Additional work consisted of the hookup of all piping systems and electrical lighting throughout, in- stallation of a public address sys- tem, and sandblasting and the painting of the vessel.

Master Marine recently extended the University of Texas's research vessel Longhorn with a 20-foot mid- body section. This addition pro- vided a new equipment room, in- creased the living accommodations, lengthened two laboratories and al- lowed the building of a spacious new pilothouse complete with crew quar- ters.

Included in the work was the con- struction of two new bottom tanks for fresh water and the installation of a central A.C. unit servicing three separate levels simultaneously.

With the move of the main deck crane to the fo'c'sle deck, a new working area along with space for two deck boats was accomplished.

Finally, to insure safety and im- prove working conditions, the gen- erators were mounted on isolators with exhaust and hydraulic equip- ment, all sound engineered.

Exhaust and engine noise was a major concern on the Longhorn. To solve this problem Maxim M31 ex- haust silencers with MSA1 spark arresting mufflers from Riley

Beaird were installed to the main engines and generators exhaust sys- tem. In the engine room, Soundown 2 LB lead and foam sound absorp- tion was installed. Other items in- cluded aluminum framed windows from Wynne Enterprises, Red Fox

MSD, and Village Marine fresh water maker. Air conditioning units are Lennox Evaporators with heat coils.

The University vessel can now provide extended trips for research teams numbering 14. With complete navigation facilities and experi- enced crew, the Longhorn is ready for oceanographic research.

The Comanche, a 16-year-old shrimp trawler was converted to a

Hondurian lobster vessel. The work entailed installation of a plate freez- er system in the fishhold, and new hydraulics. A pot hauler and cap- stan were added and the rigging was changed to accommodate lobster pots. There was miscellaneous steel renewal throughout and the pilot- house and galley were refurbished.

Other work recently completed were two Coast Guard contracts for

Newport News Yard Lays Keel

For Carrier 'George Washington'

The recent keel laying for the

George Washington (CVN-73), which will be the Navy's sixth Nim- itz Class nuclear-powered aircraft carrier, marked two firsts in New- port News Shipbuilding's 100-year history.

The placement of the Washing- ton's 730-ton keel section in Ship- way #12 represents the first time two aircraft carriers will be assem- bled simultaneously in a single ship- way. Ship way #12 is the largest of its kind in the Western Hemisphere.

The Abraham Lincoln (CVN-72) is currently under construction in the inboard section and is scheduled for delivery to the Navy in 1990.

NNS vice president John Gra- ham said that prior to the launch- ing of the Lincoln, the partially completed Washington will be wa- tertight and able to be floated out of the outboard end of the shipway.

After the Lincoln is floated out of the shipway, the Washington will be brought back into the shipway for completion, and repositioned on the same keel blocks that supported the

Lincoln. This procedure will mark another first for us, he said.

The Washington's keel laying represents a continuation of the modular construction techniques

Newport News uses to build aircraft carriers. "We've learned many les- sons from building the Theodore

Roosevelt," Mr. Graham said, "and we will continue to improve on efficiencies as we progress on both the Lincoln and the Washington."

Extensive use of computer-aided design and manufacturing (CAD/

CAM) are credited for building cur- rent aircraft carriers faster than previous carriers. Modular con- struction techniques and the greater super lift capability of the ship- yard's 900-ton-capacity gantry crane that spans the shipway, are also responsible for the anticipated earlier deliveries.

Nimitz Class carriers are 1,092 feet long and carry a 6,000-man crew and about 100 aircraft. They have a 4 Vz -acre flight deck and are approximately 24 stories high from keel to mast top. Newport News

Shipbuilding constructed all three of the Nimitz Class carriers current- ly in the Fleet. A fourth ship of the class, the Theodore Roosevelt (CVN-71), is scheduled for delivery to the Navy later this year.
