Halter Marine Group delivered Seacor

Vision, a 225-ft. (68.6-m), 12,280-bhp anchor handling/towing supply (AHTS) vessel to

Seacor Smit, Inc.

The vessel, which was built by Halter's

Moss Point Marine, is the first in a series of four contracted by Seacor to Halter.

It is designed to meet requirements for deepwater service in the Gulf of Mexico and the worldwide market, and the 23rd Halter- built offshore supply vessel to be operated by

Seacor. "This is a truly contemporary international workboat with a modern anchor handling sys- tem, a thoughtful layout to meet the needs of improved safe working conditions and accom- modations to provide crew comfort, advanced position/station keeping systems that include stern and bowthrusters, dynamic positioning and enlarged cargo capacities. It represents a leap forward from the 1980s Gulf of Mexico- style vessels to an international design," said

John Dane III, chairman, president and

CEO of the Halter Marine Group.

All-steel Seacor Vision has a 52-ft. (16-m) beam and a 22-ft. (6.7-m) deep hull.

The vessel's double bottom hull and other safety features meet SOLAS and new U.S.

Coast Guard subchapter L requirements.

Power is provided by four GM EMD 16-645-

E7B diesel engines driving through Reintjes compound reverse/reduction gears.

Propulsion is through Berg 140-in. four-blade controllable pitch propellers in Kort nozzles.
