Mid-Coast Delivers

The Clemente Guillen

Mid-Coast Marine, Inc. of Coos

Bay, Ore., announced the recent delivery of a 72-foot twin-screw towboat, Clemente Guillen (shown above), to Roca Fosforica Mexi- cana SA de CV of Mexico City.

The vessel was designed by David

J. Seymour, Ltd., naval architect of San Francisco, Calif. Home port will be Lopez Mateos, B.C.S.

The vessel was delivered under its own power to the Magdellena

Bay area of Baja California. Fea- tures of the towboat are twin- screw 12v-149 Detroit Diesel en- gines rated at 700 hp, each driv- ing four-blade Coolidge propellers in Mid-Coast Marine nozzles. The reverse gears are Twin Disc MG 520 (5:1 ratio). The bollard pull of the vessel exceeds 41,500 pounds and draws 6 feet 9 inches of water. The nozzles offer added protection to the marine life that uses the Boca de Soledad for shelter.

The duties of the towboat will be shifting construction equip- ment in the bay along with push- ing 6,000-dwt barges loaded with phosphate to the export terminal in Magdellena Bay. The pilot- house vision is superb with eye level being 32 feet above the wa- terline. Top speed for the vessel is 12.2 knots and averaged 10.4 knots in the run down the coast to its home port.

This is the third vessel deliv- ered to the Mexican firm from

Mid-Coast Marine within the past year.

MarAd Grants Subsidy

For Construction Of

Blue Line's Landing Craft

The Maritime Subsidy Board has approved Japan as the rep- resentative foreign shipbuilding center for the calculation of the differential between U.S. and for- eign costs for the subsidized con- struction of a twin-screw, steel landing craft ordered by Blue

Lines, Inc.

The estimated foreign cost of building the 83-foot, diesel-pow- ered vessel was set at $364,000.

The vessel will be built by At- lantic Marine, Inc., Jacksonville,

Fla., and is intended for opera- tion in the Caribbean. The craft will be certified to carry com- bustible and flammable liquids in

Department of Transportation ap- proved trucks.

Literature Available On

Satellite Services For

Ships And Offshore Rigs

INMARSAT, the international maritime satellite organization, has published a four-color folder containing a dozen fact sheets with detailed information on the services it provides worldwide.

Established by international

Convention on July 16, 1979, the 34-member organization will, in early 1982, assume the rendering of services now provided by the

U.S.-owned MARISAT system.

The literature describes the

INMARSAT organization and

COMSAT's relationship to it; the

INMARSAT system; coast earth stations and network coordina- tion services; ship earth stations, and services and charges. Exam- ples of its capabilities included are: 56 KBPS seismic transmis- sion service; well log data trans- mission ; offshore early warning system; modern marine manage- ment via INMARSAT. Also in- cluded is an overview of the

MARISAT market and a listing of ships and offshore facilities currently equipped with MARI-

SAT terminals.

MaK 15 years of heavy fuel operation with MaK engines

The outstanding position of MaK in the market of medium-speed heavy fuel diesel engines is not accidental.

More than 600 MaK heavy fuel engines in operation, in total more than 2 000 000 hp and more than 2 000 000 operating hours with heavy fuel of up to 420 cSt at 50°C (4050 sec Rl at 100°F). are the proof of Heavy fuel suitability,

Reliability,

Economy.

January 14, 1965:Commissioning of the first MaK heavy fuel engine on MV "Cremon" of the owners HM Gehrkens. The engine type 8Z451 of 2000 hp at 375 rpm has been running for more than 70 000 hours, mainly on heavy fuel of 30 cSt at 50°C (200 sec Rl at 100°F).
