Line), Dutch flag (Intercontinental

Transport), and French flag (Com- pagnie Generale Maritime). Of the four sister ships that will be deliv- ered this year, Kockums is building an additional two, one is being con- structed at Swan Hunter Shipbuild- ers at Wallsend, U.K., and Chan- tiers du Nord et de la Mediterranee at Dunkerque, France, is building one.

Main propulsion machinery in the

Atlantic Companion consists of a six-cylinder, slow-speed Gotaverk- en/B&W 6L90GBE diesel engine developing a maximum continuous rating of 23,800 bhp at 97 rpm, direct-connected to a Stone Manga- nese Marine propeller. Electrical power is provided by four Wartsila/

Vasa diesel engines, two 8R32 and two 6R32, directly connected to

Norsk Elektrisk/Brown Boveri al- ternators of 2,310 kw and 1,722 kw, respectively.

Main and auxiliary engines are all capable of burning heavy fuel oil, providing a "single-fuel" installa- tion. The ship is fitted with two

KaMeWa thrusters, one forward and one aft.

Considerable effort was expended in achieving a functional and eco- nomic bridge layout. The totally en- closed wheelhouse is arranged with control desks forward but having a walkway directly behind the win- dows. The bridge wing consoles are

This eliminates the "deadband' and gives your ship more effi- cient steering control through smaller and less frequent rudder move- ments. The basic SRP- 690 also permits bridge personnel to com- pensate for variations in sea state, ship speed, and loading to provide the optimum steering per- formance. Moreover, you can achieve even greater fuel savings by adding the adaptive option to the SRP-690, which features com- pletely automatic gain control. The total savings will quickly pay back your investment.

The SRP-690 is modularly designed and can be stand- or console-mounted, and includes a built-in steering repeater with an accurate vernier scale,

THE NEW SPERRY

DOPPLER LOG: BETTER THAN 1 PERCENT ACCURACY.

The Sperry SRD-331

Doppler Speed Log, like our

SRP-690, is the most advanced system of its kind. Solid-state microprocessor circuitry enables the SRD-331 to provide a ±50-knot speed readout with an accuracy of better than 1 percent.

The SRD-331 also features reduced power consumption, simplified shipboard wiring, smaller and fewer modules and an advanced display design—all of which adds up to greater effi- ciency and less cost for equip- ment and operation.

The SRD-331's electronics unit contains all transmit/receive circuits and incorporates fea- tures that provide "no-jitter" display under normal conditions, while assuring fast display re- sponse during rapid acceleration.

In addition, a "thresholding" circuit eliminates inaccuracy in speed due to signal-to-noise degradation, and as a final pro- cessing step, the SRD-331 provides a "reasonableness" logic which inhibits output of speed information that is either impossible or unlikely. This com- bination of features, exclusive to

Sperry assures your ship of steady, correct and unambig- uous readings at all times under all conditions.
