$53.2-Million Contract For

Supply Boats Signed By Halter

David E. Verlander (left), Halter vice president, ad- ministration, and Frank A. Nemec, president of Mar- sea Marine Companies, sign contracts for fourteen 180-foot supply boats. The $53.2-million package is believed to be the largest supply boat order in U.S. history.

Halter Marine, Inc. has signed contracts for the construction of 14 supply vessels for the Marsea Marine Companies. The con- tracts between the New Orleans-based cor- porations total $53.2 million, and are be- lieved to constitute the largest supply boat order in U.S. history.

The new 180-foot vessels will be capable of carrying bulk and liquid muds, diesel fuel, drill pipe, and other supplies to offshore in- stallations. They will also be equipped to fight off-ship fires, while their engine rooms will be protected by C02 flooding systems.

The contracts call for six of the vessels to be delivered in 1981, with the remaining eight vessels to be delivered during 1982.

This is in addition to a six-vessel contract package signed and delivered to Marsea

Companies in 1980.

Halter Marine, Inc. is the world's largest builder of supply vessels for the offshore oil and gas industry. The company owns and operates 10 shipyards in the Southeastern

United States.

SHIPMATES — Newly modified guided-mis- sile frigate USS Mclnerney (FFG-8) and newly developed Seahawk helicopter conduct first sea trials of an air-sea combination called the "antisubmarine warfare weapons systems of the future." Bath Iron Works recently delivered the shipboard portion of the prototype system to the U.S. Navy 11 days ahead of schedule. Called LAMPS MK

III, the combined system is intended to give warships "over-the-horizon" surveillance and attack capabilities. BIW modified structure, installed and tested unique electronics sys- tems for LAMPS MK III, as well as other electronics installations under a Navy con- tract of approximately $16 million. Com- plete testing aboard the Mclnerney of the total system, formally designated Light Air- borne Multi-Purpose Systems, is slated for

Navy evaluation in early 1981. The system is intended for installation aboard FFG-7 class frigates and Spruance (DD-953) class destroyers once it is proven.
