Propulsion Systems, Inc. To Supply Bow Thrusters For Two Ro/Ro Vessels

Propulsion Systems, Inc., 21213- 76th Avenue South, Kent, Wash.

98031, has been awarded a contract to furnish bow thrusters for two heavy lift ro/ro cargo vessels of about 3,000 dwt. These ships are being built by Peterson Builders, Sturgeon Bay, Wis. The vessels will be operated by the Gulf Trading and Transportation Company, and will service all U.S. and possibly foreign ports carrying heavy or odd-sized cargoes.

The thrusters will be driven by 600-horsepower a-c electric motors, and have controllable-pitch propellers, allowing stepless remote control of thrust from zero to full to either port or starboard.

The second of these two thrusters will be the 200th thruster delivered by PSI. These units are of the same size and type as the first thruster delivered by PSI after incorporation in 1961.

PSI now has available 14 basic thruster sizes from 24 to 3,000 horsepower of fixed or controllable pitch, available in the form of tunnel thrusters or steerable compass thrusters which, in turn, may be fixed, removable or retractable.
