MODULAR THRUSTER SYSTEM. OMNITHRUSTER ship control systems* utilize individual module thrusters of up to 1000 HP in any combination to produce desired forward or lateral net thrust. Prime movers for the Modular Thruster System may be electric, hydraulic or diesel powered in conjunction with manual/automatic or integrated control networks ADVANTAGES FOR LARGE VESSELS... • Incremental Thrust Capability • Multiple Module Reliability • Ease of Installation...

Bethlehem Steel Corp.'s Spar- rows Point, Md., yard has been proposed to build the rig, with delivery scheduled for May 1982. The requested guarantee is for $24,500,000, or approximately 75 percent of the $33,130,000 esti- mated cost of the rig. United States Cruises Acquires Title To SS 'United States' United States Cruises, Inc. (USCI), Seattle, Wash., has made the final $3-million payment for the purchase of the passenger ship United States, and received title to the vessel from the Com- merce Department's Maritime Ad- ministration (MarAd). USCI pre- sented MarAd with an irrevocable letter of credit for $3 million, and subsequently electronically trans- ferred the funds from its Seattle bank to the United States govern- ment account. It also gave MarAd a check for $24,977.60 to cover all unpaid out-of-pocket expenses for the care of the ship through March 21. The United States was built for United States Lines in 1952 by Newport News Shipbuilding and Dry Dock Company. It operated in trans-Atlantic service until it was laid up in Norfolk, Va., in 1969. It was purchased by MarAd in 1973 under the Passenger Ship Sales Act. The government in- vited bids for the sale of the ship four times over the years, but never received any considered re- sponsive to the terms of its offer- ings. In September 1978, MarAd accepted an offer from USCI to buy the vessel for $5 million. The company proposed to refurbish the vessel to provide cruise serv- ice between Los Angeles/San Francisco and Hawaii, and among the Hawaiian Islands. USCI previously paid deposits totaling $2 million toward the $5-million purchase price, and has been responsible for paying actual out-of-pocket costs for re- taining the United States at its berth at Norfolk International Terminal.
