The Lift Tide (shown above), a derrick x supply vessel operated by Tidewater Contractors, Inc., a subsidiary of Tidewater Inc., is now in U.S. Gulf service off the Louisiana coast following extended duty in the Middle East. Refitted with a new American Hoist & Derrick, Model 9760, 90-ton lifting capacity, pedestal-mounted crane, the vessel is certified by the U.S. Coast Guard for unrestricted ocean service.

The Lift Tide is 186 feet by 56 feet by 14 feet 6 inches, can operate at a minimum water depth of 16 feet, and offers mobility with moderate lift capacity. Powered by two 16- cylinder GM Electro-Motive Division engines that develop 3,600 bhp, the vessel has a top speed of 12 knots.

The anchors are lowered and retrieved by two new double-drum SMATCO DAW 55 winches mounted on the main deck.

The Lift Tide crew consists of seven personnel and a 10-member work force that includes a barge superintendent, crane operator, winch operator, foreman, welder, and five riggers. Additional personnel such as divers, diving tenders, pipeline inspectors, X-ray technicians, ultrasonic technicians, and other specialists can be added as required, as the vessel is designed to provide total accommodations for 34 persons.

Tidewater Contractors operates four other four-point mooring specialty vessels in the Gulf of Mexico in addition to the Lift Tide.
