by the company, moves on rails on the barge deck. The engine room amidships contains a diesel-driven generating set, ballast pumps, and tanks for bunkers and fresh water, mak- ing the terminal independent of land-based support facilities.

Drawing of the cement terminal to be supplied by

Saltech of Sweden to the National Cement Company to service a Saudi Arabian industrial complex.

The superstructure consists of a section containing the staff changing rooms, dining area and galley, as well as a workshop and office space. A second section houses a pack- ing plant featuring three rotating packing machines, a storage room, and machinery for elevating, hauling, screening, directing, and distributing two types of cement simul- taneously.

A number of conveyor belts run from the packing plant to the quay, where trucks can be loaded.

On arrival, bulk carriers are moored along- side the terminal. The cargo is then unloaded by the ship-unloader and transported via a longitudinal screw conveyor directly to the packing area or to the terminal cargo holds.

The system is sealed to avoid the spreading of dust, requiring only the ship's cargo hatches to be open. When not engaged in unloading cement from incoming ships, the ship-unloader can be used to move cement from the holds to the packing plant.

The terminal is also designed to be used for other bulk cargo.

Saltech, Salen Dry Cargo, and Siwertell are all companies in the Saleninvest group of Sweden.

Marine Builders Yard Delivers

Its Largest Vessel To Date

The 1,400-bhp towboat Jeanne Marie, the first of a completely new design being of- fered by Marine Builders, Inc., was deliv- ered recently to The Archway Fleeting and

Harbor Service Company in St. Louis. The previous largest vessel designed and built by the Clarksville, Ind., yard had a length of 62 feet and rating of 1,000 bhp.

The latest delivery has a length of 70 feet,

Towboat Jeanne Marie, one of three Cummins-powered vessels under construction for Archway Fleeting and

Harbor Service of St. Louis, was delivered recently by Marine Builders, Inc. of Clarksville, Ind.

October 1, 1980 beam of 26 feet, depth of 8 feet 6 inches, and average draft of 5 feet 6 inches. Pro- pulsion power is provided by two Cummins

KT-2300 diesel engines, each rated 700 bhp at 1,800 rpm.

The Jeanne Marie is designed and built with side tank construction, which is nor- mally used in the construction of larger tow- boats. Each side (wing) tank consists of five individual compartments. The vessel has six individual fuel tanks, also in the wing walls, thus providing greater stability. Also, in the event of a rupture or leak in any specific fuel tank, that tank can be isolated until re- pairs are made.

The vessel is equipped with a central fuel fill and vent system, with the main fillbox located on the side deck. Any spill that oc- curs during fueling would be directed to the slops holding tanks in the rear wing tanks.

The new craft also utilizes the builder's standard dry bilge design. Water from the stern tubes is siphoned to a central holding basin. This is fitted with a float control pump that pumps water from the stern tubes di- rectly overboard. A bilge pump system pumps bilge contents to a slops holding tank; from there it can be pumped to onshore disposal.

Other equipment in the Jeanne Marie in- cludes Twin Disc reduction gears, Lima/

Cummins generator, Kahlenberg propellers and air horn, Johnson keel coolers, Micro- phor sanitation system, NABRICO deck winches, Regency Polaris radio gear, and

Perko searchlights.

The Jeanne Marie is the first of three identical vessels being constructed by Marine

Builders for Archway Fleeting. The two sister vessels are scheduled to be delivered by the end of this year.

Mag Satellite Navigator

The Magnavox MX-1105 Satellite/Omega Navigator offers the best of both worlds, the world-wide precision of Satellite Navigation and the continous high seas coverage of the

Omega system. After two years of extensive testing, one major tanker operator has documented typical savings of 80 miles per voyage representing as much as $50,000 per year per vessel. This is above and beyond the savings achieved through the use of a conventional single channel set. With savings of this type, the MX-1105 is much more than an aid to navigation, it is a very good economic investment.

With equipment this important you want the best reliability and performance available.

Magnavox has produced over 3,000 Satellite Navigators (1100 Series) with over 30 million hours of actual operation. An impressive record!

For support that matches Magriavox's reliability, Nav-Com is ready to respond to your needs with prompt, efficient, and competent service.

Nav-Com offers the full range of Magnavox Satellite Navigators for every application and budget. For your next requirement, let Nav-Com prepare a professional, engineering level proposal at no cost or obligation.
