Trinity Marine Group To

Build Navy Oceanographic

Research Ship

The Trinity Marine Group has been awarded a $20.9-million con- tract by the U.S. Navy to build a 263-foot oceanographic research ship. The 3,200-ton, diesel electric, dynamically positioned AGOR-23 will be operated by the University of

Washington.

The design of the new class of research ship is a result of a national competition won by Trinity's Halter

Marine, Inc., with assistance from

Guarino and Cox, the New Orleans naval architecture firm.

The all-steel AGOR-23 will be 263 feet in length, with a 16.5-foot de- sign draft, and 52-foot molded beam. Main propulsion power will be derived from a bank of diesel- driven generators.

The vessel will have trackline ca- pability to maintain course within a 300-foot band. It will be served by a global reference system which elec- tronically integrates with two azi- muthing drives, or 360-degree rotat- ing propellers and a 360-degree ca- pable bow thruster. Trackline abili- ty is enhanced because the azimuth- ing drives eliminate propeller drive shafts or conventional steering per- mitting the propellers to pivot in any direction.

AGOR-23 will include cranes,

Electronically switches up to 3 displays and transceivers, with CRT diagrams, for single/simultaneous 3 or 10-cm operation.

Comparison

Tests Prove

PATHFINDER/ST

Radars See What

Other Radars Can't.

In side-by-side comparison tests, a

PATHFINDER/ST display and a conven- tional radar display were connected to the same radar system. PATHFINDER/ST consistently displayed targets not detec- ted by the conventional display.

Optimum Resolution

Displays are

Clearly Superior.

PATHFINDER/ST raster scan PPI images are refreshed 50 times each second. This eliminates the annoying "flicker" found in other radar systems.

The number of pixels has been carefully chosen for optimum resolution. The re- sult is an extremely sharp, ultra-bright image that is easy to view, day or night.

Superior Technology

Will Clearly Fit

Your Needs.

PATHFINDER/ST Radars satisfy a very wide range of installation and operating requirements. Signal multi- plexing reduces connections between

PATHFINDER/ST receivers and dis- plays. This, combined with electronic interswitching for dual systems, the abil- ity to mount transceivers "up" in antenna pedestals, or "down" in separate cabi- nets, and keyboard entry of all set-up parameters, makes any installation straightforward, simple, and economical.

In addition to having the optional IMO- required, antenna-mounted performance monitors, PATHFINDER/ST Radar soft- ware provides menus for extensive self- testing of virtually every function.

Worldwide Approval and Support.

Raytheon PATHFINDER/ST Radars are designed to meet or exceed all applica-

IMO and the national regulatory agen- cies of countries worldwide.

They are backed by extensive worldwide support and service facilities, located in major ports everywhere.

Completion of the vessel, which will be built at one of Trinity's two shipyards in the Moss Point, Miss., area, is scheduled around the end of 1989.

Two Halter-designed and built

Navy oceanographic vessels, the

Moana Wave, and the Gyre, are operated by the University of Ha- waii, and Texas A&M, respectively.

John Dane III, president of the

Trinity Marine Group, said AGOR- 23 will be able to reach 15 knots transit speed in sea state four, three knots faster than the previous re- search ships.

Bombardier To Supply

Engine Blocks For

Detroit Diesel Engines —Literature Available

Roland Gagnon, president of the Rail and Diesel Products Divi- sion of Bombardier Inc., Montreal,

Canada, recently announced that

Bombardier will supply engine blocks for Detroit Diesel Corpora- tion's 149 Series V8, V12 and V16 models under an agreement be- tween the two companies.

Representing a minimum sales revenue of $30 million, the first units will be delivered in June 1989.

It will generate the equivalent of 350 man-years of work and will be car- ried out by Alco Power Inc., a Bom- bardier subsidiary located in Au- burn, N.Y. The agreement will ena- ble Bombardier to reorganize a sec- tion of its Auburn plant into a high- tech manufacturing center dedi- cated to this contract and is part of the restructuring of the firm's diesel engine manufacturing capability.
