The 140-foot by 42-foot forecastle tugs will feature outboard main en- gines driving two Niigata Z-Pellers

ZP-4 with 102-inch-diameter wheels. The centerline engine will drive a 113-inch-diameter conven- tional open wheel. The propulsion engines will be owner-furnished and they will be channel cooled. The vessel's electrical service will be pro- vided by three 99-kw generators.

ABS Publishes Its First

Guide For Certification

Of Thrusters

American Bureau of Shipping (ABS) has published the first edi- tion of its "Guide for Certification of Thrusters." The Guide provides for the certification of various thruster systems such as main pro- pulsion thrusters, propulsion assist thrusters, athwartship thrusters, and dynamic positioning thrusters.

Compliance with the provisions of this Guide is required for main pro- pulsion thrusters as a condition of classification, but is optional for the other thrusters.

Requirements in the Guide cover equipment and system design, and apply to thrusters driven by diesel, steam, or gas turbine engines, and electric or hydraulic motors. The

Guide requirements cover the tun- nel, pod-type and omni-directional type thrusters.

The 30-page Guide contains the following sections on thrusters with various subjects covered on each: conditions of classification; machin- ery design; prime movers; plans and particulars; propellers; reduction gears; shafts; systems; dynamic po- sitioning machinery; and surveys. A special section, Appendix A con- tains Guidelines for Type Testing of

Control Components. This section covers vibration and functional test- ing.

Cost of the "Guide for Certifica- tion of Thrusters" is $6 in the U.S. and $7 elsewhere. Mail orders to:

THE POWER

THE ACCURACY

THE RELIABILITY

YOU NEED

Goltens' -Pump

Tensioning. Jacking.

Bolting. Tasks that re- quire great power and extreme accu- racy. The G-Pump delivers both. Time after time. Task after task,

Compact and portable, the

G-Pump will supply and maintain hydraulic pressure up to 21,300 psi (1,500 kp/cm2) with extreme accuracy. When ten- sioning or bolting the G-Pump can be preset to automatically maintain a specific pressure with an accuracy that is hard to find in a unit of this size.

Every rugged, reliable, preci- sion G-Pump is equipped with a safety valve to prevent accidental overloading. A water resistant, stainless steel model, specially designed for offshore use, is also available.

Get the power, the accuracy, the reliability you need from a hydraulic pump. Get the G-Pump. Its perform- ance under pressure is remarkable!
