Halifax Lays Keel For First of Two OSV's

Halifax Shipyard has laid the keel for the first of two large Offshore Supply and Anchor Handling Vessels for Atlantic Towing Ltd.

Known as hulls 88 and 89 for the yard, the vessels have been identified as UT 722 L type, and are similar to Atlantic Eagle and Atlantic Hawk - both of which were built at the yard in 1999. They are currently deployed in support of the Canadian East Coast offshore oil industry.

Measuring 262 x 59 x 22 ft. (80 x 18 x 6.6 m), the vessels will have four main engines, each at 4,000 kW, which will give them a maximum speed of 17+ knots, and a bollard pull of approximately 180 tons. Designed to carry more than 2,700 tons of cargo, mixed between containers on deck and liquids in the tanks, the vessels will be able to provide an onboard survivor capacity of 300 persons in a rescue and stand-by mode.

Deep water anchor handling, and towing duties will be conducted via the 500- ton pull, double drum, winch. Among the largest available in the world to the OSV fleet, these winch drums can load more than 4,000 m of 3.75-in. diameter steel wire rope.
