ROWAN GORILLA III

Marathon

Built by the Vicksburg, Miss., yard of Marathon LeTourneau for

Rowan Companies, Inc. of Houston, the drilling rig Rowan Gorilla III left Belle Chasse, La., in 1985 under tow of the 22,000-bhp oceangoing tug Smit London for the 2,000-mile trip to offshore Nova Scotia, Cana- da. During the voyage the tug re- ceived propulsion assistance from the operation of the rig's twin 112- inch propellers in Kort nozzles driv- en by eight electric motors with 6,800-hp total output.

The new unit is the third in a series of the largest self-elevating jackups built by Marathon LeTour- neau Offshore Company for Rowan.

They are of a new and heavier class intended to drill up to 30,000 feet in water depths up to 328 feet in any ice-free hostile environment in the world. In less hostile environments, they are capable of drilling in water depths of more than 400 feet.

These 15,000-ton rigs require twice the amount of fabricated steel used in the previously largest jack- ups. At 297 feet by 292 feet, the

Gorilla Class rigs are nearly 40 per- cent bigger than the Marathon 116

Class jackups.

SANDY HOOK

Gladding-Hearn

The Sandy Hook Pilots Associa- tion of New York and New Jersey recently took delivery of the 64-foot dispatch boat Sandy Hook. The all- aluminum, twin-screw vessel was built by Gladding-Hearn Shipbuild- ing/The Duclos Corporation of

Somerset, Mass., and designed by C.

Raymond Hunt Associates of Bos- ton with a deep "V" hull.

The new vessel is powered by two

M.A.N.-B&W D2452 V-12 diesel en- gines, each developing 545 bhp at 1,800 rpm, providing a top speed of 24 knots and cruising speed of 20 knots. The power train includes

Columbian Tetradyne propellers,

Armco Aquamet-22 shafting, and

L&S Marine reverse/reduction gears with a ratio of 2:1.

Topside, the Sandy Hook has a spacious midships cabin divided into pilothouse and salon areas.

Both are electric baseboard heated and fully air conditioned with Ma- rine Air Systems equipment. In the well-equipped pilothouse, the cen- ter helm has a vertically mounted, 30-inch destroyer type wheel con- trolling a Hynautic hydraulic steer- ing system. Lexan skylights over the helm area and double-hung win- dows in the aft bulkhead provide added ventilation when the air con- ditioning is not in use.

The salon area provides a roomy and comfortable space for commut- ing pilots. Six reclining chairs on a raised platform occupy the star- board side, and two more are lo- cated forward on the port side. Win- dows and ports in the salon are of tinted glass.

Below-deck quarters offer accom- modations for 10, with six bunks in the midships area and four bunks forward. There are two toilet com- partments, one of which includes a shower, located between the berth- ing spaces.

On deck, walkways from the en- gine room forward, as well as hand- rails from the cabin doors forward, are hot-water-heated for safety in winter weather. Hull guards include

Johnson 7-inch-diameter tendering and slanted strakes of D-section rubber.

SANTA CRUZ

Hope/Progressive

The 67-foot patrol boat Santa

Cruz de la Sierra was delivered dur- ing 1985 by the Hope/Progressive shipyard in Houma, La. The diesel- powered vessel, ordered by the Nav- al Forces of the Republic of Bolivia, was built under contract with Napco

International of Minneapolis, an in- ternational marketing firm that supplies a full line of defense- related products to the U.S. Govern- ment and the governments of more than 60 countries around the world.

Hope/Progressive is an estab- lished group of companies specializ- ing in fabrication of offshore struc- tures, oilfield equipment, and living quarters modules, and in construc tion of high-performance aluminum vessels.

SPEED TIDE

Bell Halter

Tidewater Marine Service, the marine subsidiary of Tidewater, Inc. of New Orleans, recently took de- livery of the Speed Tide, a 110-foot

Surface Effect Ship (SES) on long- term charter from the vessel's owner and builder, Bell Halter, Inc., also of

New Orleans.

As this vessel represents a new dimension in offshore support ser- vices for Tidewater, its performance will be closely monitored and evalu- ated in order to determine the feasi- bility of adding equipment of this type to the Tidewater fleet in the future. The new vessel will work in the Gulf of Suez for the Gulf of Suez

Petroleum Company, a joint ven- ture of Egypt's national company and Amoco.

The Speed Tide's principal char- acteristic is that it is air-supported, with catamaran type, rigid side hulls. A cushion of air trapped be- tween the side hulls and flexible bow and stern seals lifts a large part of the side hulls clear of the water to reduce drag, thereby producing greater efficiency and higher speed.

The lower parts of the side hulls remain in the water to aid in stabili- ty and maneuverability.
