New MTU-ZF Propulsion

Powers Swiftships-Built

CO-MAR Crew/Supply Vessel

Swiftships, Inc. of Morgan City, La., has announced the completion of a 120-foot, all- aluminum crew/supply boat named C/Raider.

This vessel is the first purchased by CO-MAR

Offshore Corporation, also of Morgan City, to employ a ZF 2y2:1 reduction gear.

MTU engines combined with the ZF gears allow the craft to use a larger propeller. This results in the vessel being able to transport heavier loads at higher speeds.

Paul Haines Jr., owner of CO-MAR, stated: "Many of our vessels are powered by MTU engines. However, this is our first experience using ZF gears with the MTU engines. "We have to say that the C/Raider is one of the most impressive boats we've taken delivery on in terms of performance and ease of handling." Mr. Haines acknowledged that CO-MAR has contracted for four sister vessels with the MTU ZF power gear pro- pulsion units.

A twin-screw vessel, the C/Raider has a propulsion package consisting of two MTU 12V331 engines and ZF gears. A Delco 30-kw generator is driven by two Detroit Diesel 3-71 auxiliary power engines. On its sea trial, the crew/supply boat attained speeds up to 25 knots.

Having passed United States Coast Guard inspection, the C/Raider is certified to carry 65 persons, aviation fuel, and corrosives. It also provides living quarters to accommodate a five-man crew.

With a cargo deck size of 58 feet by 16 feet, C/Raider's cargo capacity above deck

Using MTU-ZF power gear propulsion units, the

C/Raider, a crew/supply boat built by Swiftships, Inc. for CO-MAR Offshore Corporation, hauls heavier cargo at faster speeds. is 110 long tons, while below deck its capac- ity is 52 tons. It maintains a 6-foot draft loaded, 3-foot light.

The tanks hold 3,740 gallons of fresh wa- ter, 13,350 gallons of drill water, 500 gallons of drinking water, and 4,000 gallons of fuel which gives the vessel an endurance of 40 hours.

Columbian supplied the propeller, a four- blade, 42-inch by 38-inch Crewboat Bronze.

Electronics were installed and supplied by

Bibbins & Rice. They include a Furuno ra- dar, two radiotelephones, an SSB Drake

TRM 1 and a VHF Drake MRF-55, a Texas

Instruments TI-9900 automatic Loran, an

Impulse 600CV depth sounder, and a Dan- forth C654C compass.

The vessel is equipped with lifesaving gear, full fire-fighting capabilities, and air- conditioning and heating throughout. It also carries a full complement of other safety features and navigational equipment onboard.

Swiftships' project engineer, Calvin Le

Leux, reports that C/Raider passed all tests and will be placed into petroleum operation in the Gulf of Mexico.

Saltech Floating Cement

Terminal Ordered For

Saudi Arabian Port

Saltech, a company in the Saleninvest group of Sweden, has been commissioned by the National Cement Company (NCC), the

Saudi Arabian company based in Jeddah, to design and act as main contractor for the construction of a floating cement terminal that will be sited initially in the port of

Yanbu.

The terminal, which has been designed to handle 1.5 million tons of cement per year, will service a new industrial complex to be built in the port area during the next five years. The complex will include refineries, gas-condensation works, petrochemical/tech- nical factories, and cement plants, as well as new quays and all support facilities needed for a modern industrial area.

The large quantities of cement required for construction work will be shipped to the terminal in bulk carriers for unloading, in sacks and bulk, into trucks for transport inland. In due course, when construction of the complex draws to a close and the local cement plants are completed, the terminal can be towed to another site where cement imports have to be handled.

The terminal, which is to be built by a

Far Eastern shipyard, is scheduled to be in position and to come into operation in Octo- ber 1981. Salen Dry Cargo and Saltech will operate the terminal for NCC.

The terminal incorporates a barge with ordinary cargo holds and large hatches. An 800-ton-per-hour ship unloader manufac- tured by Siwertell, the largest ever delivered get the best —
