SS Mormacsea— (Continued from page 6) 30,000-shp at 110 propeller rpm geared steam turbine, turning a single six-bladed Baldwin

Lima Hamilton propeller. The turbines ex- haust to a Foster Wheeler main condenser.

The line shaft, supplied by Jorgenson, is sup- ported by American Metal line-shaft bearings.

The tail shaft is supported by a Waukesha stern-tube bearing.

Two Combustion Engineering V2M-8 welded-wall boilers provide steam at an op- erating pressure of 870 psig and a temperature of 955°F. at the superheater outlet. Normal capacity is 102,110 pounds of steam per hour, with an overload capacity of 117,390 pounds of steam per hour. Each boiler is fitted with two C-E Wallsend oil burners and registers and one C-E Ljungstrom regenerative air heat- er, Model No. 15VMX-44, with 10,000 square feet of heating surface.

The other major machinery items are: 20,000 gallons per day Aqua-Chem distilling units,

Worthington main condensate and circulating pumps, Pacific main feed pumps and Buffalo

Forge force draft blowers.

Two Worthington turbo-generators supply the ship's service electric power load of 1,500 kw. An emergency diesel-generator, supplied by Stewart & Stevenson, is installed outside the engine room.

The ship is highly automated and has one of the most advanced bridge consoles in any commercial ship. The central operating sys- tem console was supplied by the Aetron Divi- sion of Aerojet General Corporation. The en- gine room console is fitted with all the neces- sary controls for remote operation of the ma- chinery plant and also has a Marine Electric bell logger. Control is easily transferred be- tween the engine and bridge, with the engine room having take-over powers if required.

A unique feature of this class of ships is the method of loading and storing the refrigerated stores for the crew and passengers. Three dual- compartmented refrigerated containers built by Dorsey Trailers with plug-in Thermo-King refrigerating units are used in place of built-in reefer compartments. These 20-foot units are pre-stored ashore and loaded on the vessel while cargo is being handled. In this manner, the crew is not required to handle stores from the deck to reefer compartments.

The pilothouse is completely outfitted with the latest equipment for efficient and safe navi-

Officers lounge was designed by the Line's staff and pro- vides a cheerful relaxation area for off-duty officers. gation. ITT Mackay supplied the radio tele- graph, echo depthsounder, loran receivers, ra- dio direction finder and the facsimile recorder.

Two RCA radars are installed, one is a 10 cm set and the other a 3.2 cm unit. Besides this electronic gear, there are a Sperry Piedmont gyro compass and a Baker Lyman magnetic compass.

The Western Gear steering gear is-controlled by a Sperry Marine steering control transmis- sion system fitted with a course recorder and a

Henschel rudder angle indicator system.

The design of the Mormacsea and her three sisterships proceeded concurrently with the de- sign of terminals and other facilities, thus pro- viding for optimum results.

In order to meet the needs of the shippers, the railroads and the truckers, in this country and abroad, the combination ships were tailor- ed to meet the vertical cargo movement of the lift-on/lift-ofF type of vessel and not conflict with the horizontal movement of the roll-on/ roll-off cargo through the stern ramp.

In addition to the feature of being able to roll cargo on the ship while other cargo is be- ing lifted on board, facilities have been made available to pump up to 2,800 tons of liquid cargo simultaneously, all of which helps to reduce port time.

The constantly increasing costs of ships and labor, the intense competition in foreign mar- kets and the over-riding need for a means to hold the cost line in international trade moti- vated the company to provide this entirely new- concept in ship design, which increases the ef- ficiency by decreasing unproductive port time, thus lowering the unit costs.

Officers' and passengers' dining room indicates the care shown by Moore- McCormack in accommodation design.

Steering gear was provided as a complete unit by Western

Gear Corporation. It is operated by a Sperry system.

Loading of Dorsey refrigerated stores container equipped with Thermo-King units is tested at the shipyard. Stores containers are pre-loaded on the pier, thus reducing turn-around time of ship.
