which generally involves silt, sand, gravel and soft clay. Its jetwater instal- lation allows for dredging of densely packed material. The Coastway is also prepared for the desalination of sand from sea. The adjustable dredge pump speed by a special type gearbox pro- vides the control of the mixture speed and power.

Boskalis will deploy the Coastway primarily for dredging operations on short and medium-range distances.

The Coastway, ordered by Boskalis in

December 2000, will be complete at the yard for commissioning and will be put to service by March 2002.

Almirante Brion Undergoes Sea

Trials At Litton Ingalls

The LUPO Class frigate Almirante

Brion (F-22), which is undergoing a modernization for the Venezuelan

Armada by Northrop Grumman's

Ingalls Operations, Pascagoula, Miss., sailed through the Gulf of Mexico dur- ing the ship's first sea trial, Oct. 17-18, 2001. During the sea trial, various sys- tems were tested including propulsion, electronics and communications. The ship's combat systems was tested during a second sea trial in November. Ingalls is also performing similar work on a second LUPO Class ship, Mariscal

Sucre (F-21), which has completed first trials and goes on combat systems trials later this month.

Joint Venture Commissioned

Into U.S. Military Service

The commissioning of the Incat-built 315-ft. (96-m) Wave Piercing Sealift

Catamaran contracted to the United

States military for a deployment of two years, has taken place at Norfolk, Va.

The vessel will serve to enhance mission capability in a broad range of scenarios and this is expected to lead to the acqui- sition of more tonnage in the future.

The contract between the U.S. Army's

TACOM (Tank-Automotive and Arma- ment Command) and Bollinger / Incat

USA, L.L.C. is the first major project undertaken by the strategic alliance formed last year between Bollinger

Shipyards of Louisana, U.S. and the

Incat shipyard in Tasmania, Australia.

Joint Venture is the first high speed craft to go into service with the United

States military forces. Undergoing a major refit in September 2001 the craft has been upgraded and fitted with mili- tary enhancements such as the heli- copter deck, stern quarter ramp, RIB deployment gantry, troop facilities, crew accommodation and more. The craft emerged from Incat's new Wilson's dry- dock, having been transformed and capable of carrying 363 persons, mili- tary vehicles and equipment over 1110 nautical miles at a speed greater than 35 knots.

Halter Receives Outstanding

Rating From U.S. Navy

Friede Goldman Halter's marine seg- ment received an outstanding rating for the completion of the USNS Mary Sears sea trials. Rear Adm. William Schmidt of Insurv and U.S. Navy captain Philip

Johnson of Supships Pascagoula partici- pated in the trials along with personnel from the U.S. Coast Guard, Navy Insurv

Board, Naval Sea Systems command,

Military Sea Lift Command, Pascagoula

Supervisor of Shipbuilding and the

Naval Oceanographic Office.

The sixth Pathfinder T-AGS 60 class built for the Navy by Halter Marine,

USNS Mary Sears is a multi-mission oceanographic survey ship capable of surveying in either coastal or deep- ocean waters, and always forward deployed- having no stateside homeport.

The vessel is the first oceanographic ship officially christened with a woman's name; WW II wave, Mary

Sears, who was known for her intelli- gence reports predicting the presence of thermoclines — areas of rapid water f" :*

I I i1 US' • jsJPterr temperature change — under which a submarine could hide to escape enemy detection.

The T-AGS 60 class is designed with a common bus diesel electric propulsion system consisting of twin screw pro- pellers driven through Z-drives. The Z- drives, which have been installed on several new and converted oceanograph- ic ships, include gear reduction and 360 degree thrust direction control in a com- pact unit.

The elimination of conventional reduction gears and long propeller shafts, frees up space for other oceano- graphic uses. Dynamic positioning con- trols thrust direction and provide unpar- alleled ship control and maneuverability to permit precise position keeping and track line following. Continuous vari- able control of the vessel's speed can be maintained from three knots up to max- imum speed.
