Halter Marine, Inc., of New

Orleans, La., and Maritime En- gineering A.S., of Oslo, Norway, have signed an agreement grant- ing Halter exclusive rights in the

U.S. to build all of the ME series vessels in excess of 201 feet.

Halter also has the license on a nonexclusive basis worldwide.

Maritime Engineering A/S is a well-known marine engineering and naval architecture firm with a successful history of designing a variety of vessels that serve offshore oil fields in some of the most hostile seas in the world.

In making the announcement,

R.J. Shopf, president of Halter

Marine said: "This agreement reflects our interest in offering a proven line of versatile vessels that can work in such areas as the North Sea, Beaufort Sea,

North Atlantic, and just about any hostile weather area in the world. The Maritime Engineer- ing vessels give us proven de- signs, backed by extensive cold water experience coupled with the high-quality productivity of our six shipyards."

He added Halter will continue to offer its own line of vessels including its new 225-foot Sea

Titan series, and indicated that even larger designs are on the

Halter drawing boards now.

Two of the Maritime Engineer- ing vessels that are available now from Halter are the ME 303 and ME 202. The ME 303 is a deepwater, anchor/handling, tug7 supply boat designed to handle the anchors of the new gener- ation of semisubmersible drilling rigs.

The 223-foot, 12,000-bhp ves- sel features large capacities and deadweight carrying capabilities, a sophisticated two drum anchor' handling winch with over 150- tons of winch pull, a carefully planned layout including allow- ances for fire fighting, and eco- nomical engines that allow for the use of heavy bunker fuel.

The ME 202 is a 220-foot, 6,000-kva, 7,200-bhp, diesel elec- tric platform supply vessel. It is designed to carry a higher pay- load than normal supply boats while remaining within conven- tional size. Twin screw, independ- ent spade type rudders with two bowthrusters forward and one aft make the vessel highly ma- neuverable.

Cargo discharge from the ME 202 should be possible in winds up to 40-knots and a 3-knot cur- rent without using anchors by use of a combination of 360- degree azimuthing main propul- sion units, two 2,000-bhp, two 900-bhp bowthrusters, and joy- stick control.

The ME 202's high fuel econ- omy is further enhanced by the design's allowance for the use of heavy bunker fuel.

Alaskan Office Opened By

Global Marine Divisions

Global Marine Development

Inc., Newport Beach, Calif., (GMDI) and Oceanographic Serv- ices Inc. (OSI) Goleta, Calif., jointly announced the opening re- cently of their Anchorage liaison office in the newly constructed

Frontier Building.

Manager of the new office is

Harold Ramsden of Global Ma- rine Development Inc. Mr. Rams- den was formerly manager of construction, estimating, and contract administration for Glo- bal Marine before becoming man- ager of sales in 1977.

The office was opened as a re- sult of the increasing level of offshore oil activity in Alaska such as the recent Diapir Field lease sale.

Global Marine Development and Oceanographic Services are divisions of Global Marine Inc., a major international offshore drilling contractor. Global Ma- rine Development Inc. is the development arm of Global Ma- rine Inc. One of its principal ac- tivities is the design and devel- opment of specialized steel and concrete offshore structures for drilling in the Arctic.

Oceanographic Services Inc. has spent many years in devel- oping and installing instrumenta- tion and taking measurements of offshore Arctic ice, wave, and bathymetry conditions.
