Halter Marine Completes

Contract With Tidewater -mmSm

The 192-foot supply boat Tiger Tide, built by Halter Marine for Tidewater, is powered by EMD engines.

Halter Marine, Inc., New Orleans, La., has completed an 11 supply boat contract with

Tidewater Marine, Inc. with the delivery of the 192-foot Tiger Tide.

The Tiger Tide is 192 feet 6 inches with a 40-foot beam and 14-foot depth. She is pow- ered by two EMD 16-645E7B diesel engines developing 2,305 hp each at 900 rpm. They drive two 90-inch-diameter four-bladed pro- pellers through Lufkin RH 2322 reverse/re- duction gears with a ratio of 3.0:1. The main engines and gears are cooled by six Fernstrum grid coolers.

There are three Mathers pneumatic control systems aboard and a 24-point engine alarm system provided by SSI. The hydraulic/electric steering system was also supplied by SSI. A

Schottel S-152L bow thruster driven by a De- troit Diesel 8V71 improves station keeping and maneuverability. The main switchboard, distribution panels, and generator control panels were manufactured by Continental

Electric Service Corporation. Auxiliary power is supplied by two Detroit Diesel 8V71 diesel engines through two Delco 125-kw generators.

Aurora pumps service bilge, ballast, fuel oil transfer and the on and off ship fire-fighting systems. The fuel oil separator was manufac- tured by Westfalia. The sanitary water sys- tem contains a Myers pressure set with an 82- gallon Harvard tank.

Navigation and communications equipment include: two Decca RM916C radars; a Furuno

P860F sounder; two Sailor VHF radios; Rit- chie compass; a RFM230M SSB radio; an NCS

Wherefinder II; a Sperry MK37 Gyro with re- peater; and a Sperry 8T autopilot and gyro interface.

Some of the deck equipment includes: a

Smatco 72 DAW double drum tow/anchor- handling winch driven by a Detroit Diesel 12V71 engine with a line pull of 150 tons; a

Smatco 1500 EAD-30 anchor windlass with a 35,000-pound line pull; a Smatco single drum hydraulic tugger with multiple disc brakes; and a 5-foot by 8-foot Halmar stern roller.

Living and working spaces are heated and cooled by a 17-ton Carrier system. Eight staterooms provide berths for 16 persons.

The Tiger Tide was built at Halter's Moss

Point, Mississippi division, one of six ship- yards owned and operated by Halter in the

Southeastern United States. Halter is One of

Strut Drive Propulsion Units —Literature Available

The 49-foot Pacific Pilot Six is powered by Detroit Diesel en- gines and Maritime Industry "strut drives."

Maritime Industries Ltd., Vancouver, Can- ada, supplied the propulsion units for the re- cently commissioned Pacific Pilotage Author- ity vessel, Pacific Pilot VI, now in service as a pilot boat from Victoria, B.C., Canada.

The vessel was designed by David Moore of

Shore Boatbuilders who were also the con- structors of the vessel. The overall length is 49 feet and it has a service speed in excess of 20 knots.

The twin strut drive offers unique advan- tages in both performance and space. They are commercially rated and robustly designed to withstand impact such as log debris. Strut drive also provides horizontal thrust, thereby increasing performance compared with con- ventional shaft drives. Casings for the Model

MC-300 and its larger companion, the MC- 500, are constructed of aluminum. The en- gines driving these units are Detroit Diesel 8V71's, rated at 286 hp at 2,100 rpm. Current applications for the unit also include crew- boats and luxury yachts. The technology of the strut drive is based on Maritime's 15 years' experience in steerable drives which they have manufactured in horsepowers up to 3,000.
