PSI Completes Total Package Concept With Todd 'Apache' Contract

Propulsion Systems, Inc. of Kent, Wash., was recently awarded a contract by Todd Shipyards, Galveston Division, to supply the controls package for Santa Fe International's pipelaying vessel "Apache." The controls package is in addition to the twin controllable- pitch propellers, side thrusters, and rotary vane steering gear already supplied by PSI.

The Apache is a new generation of special-purpose ships designed to utilize a computercontrolled automatic station-keeping system. This system allows complete, commanding control of the vessel's propulsive and steering equipment to keep the ship within feet of its assigned position.

One of the contributing factors to this high degree of accuracy is the function of the PSI control system. It will interface with and operate the main propulsion, thruster, and steering gear package in conjunction with the automatic station-keeping system.

The equipment will be constructed at PSI's Kent facility, with delivery expected in the fourth quarter of 1978.

Propulsion Systems, Inc. is a marine systems engineering and manufacturing firm. The concern designs, m a n u f a c t u r e s and/or supplies propulsion systems including prime movers, controllable- pitch propellers, steerable and tunnel thrusters, rotary vane steering gear, control systems, and instrumentation for the marine industry.
