Advanced Vessel To Join Fleet

Of Tidewater Marine Joint Venture

One of the most advanced ves- sels to go into service for Tide- water Marine Service, Inc.'s Aus- tralian joint venture company,

Tidewater Port Jackson Marine

Pty., Ltd. of Sydney, was nearing completion at Carrington Slip- ways, Newcastle, New South

Wales, when the photo above was taken. The vessel is the Flinders

Tide, named in honor of the 18th century explorer Capt. Matthew

Flinders, Royal Navy, who dis- covered and charted large areas of Australia's coastline, with em- phasis on the Bass Strait, where the vessel is expected to operate. "Flinders Tide is designed to provide support for a remote- controlled vehicle (RCY), which is an undersea submersible used to survey and monitor pipelines and underwater construction, and to aid seabed survey work. The vessel also has important second- ary functions that include diving and firefighting roles," according to Ray J. Hope, executive vice president of Tidewater Marine

Service, Inc., and J.C. (Bill) Need- ham, manager of Tidewater Port

Jackson Marine Pty. According to Mr. Hope and Mr. Needham,

Flinders Tide will be among the most advanced vessels currently engaged in the offshore oil and gas industry and will rank high among the world's most special- ized offshore support equipment. "The RCV, attached to the ves- sel by cable, will propel itself along the ocean floor, or pipeline, and will relay pictures by tele- vision camera to the mother ves- sel. It is equipped with remote- controlled arms capable of han- dling small objects, wire, shack- les, or tools, and is remarkably versatile," they said.

The Flinders Tide will be able to keep station on the RCV by operating in the dynamic posi- tioning mode, maintaining posi- tion automatically in winds up to 20 knots with associated seas, plus two-knot current, either from the same or different direc- tions.

Approximately 51 meters (167

February 1, 1981 feet) long, the new support ves- sel will be powered by twin EMD 12 cylinder 645-E6 main engines having a total of 3,000 hp (maxi- mum continuous) at 900 rpm, driving controllable-pitch propel- lers, and three 600-hp Ulstein transverse thrusters. When in the dynamic positioning mode, the main engines will run at constant speed and control of the main propeller pitch, three transverse thrusters, and twin rudders will be effected by a Honeywell A.S.K. model 3100 computer. The system will be capable of using either a

Decca "Trisponder" surface net- work or a Honeywell RS 902 hy- dro-acoustic subsea beacon posi- tion reference system.

The RCV will be deployed through a 10-meter-diameter "moon pool," and when engaged in seabed recovery work, will be used in conjunction with deck winches and a hydraulically oper- ated hinged "A" frame stern gan- try of 30-ton S.W.L. Two 50-ton, two 10-ton, and two 3-ton hy- draulic deck winches will be fitted.

The Flinders Tide has accom- modations for divers, and when working in this mode the vessel can be moored in a four-point mooring system pioneered by

Tidewater Marine. The vessel's anchors will utilize the general- purpose winches and windlass. In diving support work, a saturated diving system can be provided on deck, and the bell will be deployed through the moon pool which is capable of aeration for this pur- pose. Workshops and RCV con- trol room are provided onboard.

A firefighting system capable of delivering 2,400 tons of water per hour will be installed. The two remote-controlled monitors will be fitted atop a special gan- try crane at the stern. Each will be powered by a 960-hp diesel pump capable of discharging wa- ter a distance of 145 meters to a height of 40 meters (475/131 feet).

The Flinders Tide was expected to go into service in January 1981.
