These fluids are: ? Placed low in the ship and do not use valu-able cargo space ? Available at densities up to 150 pounds per cubic foot, allowing maximum use of avail-able tankage ? Classed as permanent ballast and approved by USCG and American Bureau of Shipping ? Usually less costly than other heavy perma-nent ballast ? Easier to remove; can be stored and re-installed ? Maintenance-free ? Non-corrosive ? Non-combustible and will not support combustion Baroid Ballast Fluids have been in successful use on many ships since 1963. Baroid prepares and installs these fluids at all continental U.S. ports and shipyards. m\ For more information contact: BAROID DIVISION NATIONAL LEAD COMPANY, P.O.

YUkon 1-3500 ESTABLISHED 1899 RENEWAL PARTS EDO Western Docking System Going On 312,000-Dwt Tanker The first ship to use EDO Western's new Model 482 NAVTRAK docking system will be one of the six 312,000-dwt tankers being built in Japan for National Bulk Carriers for long-term charter to Gulf Oil Corporation. This ship is scheduled for delivery in February. Another installation will be made on Nomikos (London) Ltd. new 250,000-dwt tanker, Alexander the Great, building in Japan and scheduled for delivery in 1970. With the advent of the giant supertankers, berthing and mooring has become a problem. The gentlest of 'bumps' by a 300,000-ton ship, for example, can cause considerable damage. The EDO Western Corporation, Salt Lake City, Utah, a subsidiary of the EDO Corporation of College Point, N.Y., has developed a computer-ized sonar docking system for use on large vessels. The digital-computation and sonar equipment serves as an instantaneous four-direction recorder of absolute over-the-bottom velocities. It meas-ures the fore or aft speed, and also the bow and stern lateral movement of the ship either to port or starboard, displaying the results in feet per minute and at one-second intervals. EDO Western's Model 482 NAVTRAK em-ploys the so-called Doppler effect. The digital computation system of the NAVTRAK docking sonar translates the Doppler-effect information into bow and stern lateral velocities, either to port or starboard, and fore or aft velocity. It automatically adjusts for error that could occur because of variations in water temperature and salinity. The electronic equipment also compen-sates for ship motion (pitch, roll, yaw and heave), providing real over-the-bottom velocities with ac-curacy estimated at 99 percent. The computer transmits the figures on fore or aft and bow and stern movement second by second to a primary display panel on the bridge and to optional remote panels in either or both wings of the ship. Two transducers, which send and receive the sonar signals, are hull-mounted, one fore and the other aft. They can be installed in sea-chest assemblies to permit removal without the need for drydocking. Operating conditions for the NAVTRAK dock-ing equipment range from a minimum of one foot clearance beneath the hull of the ship to water depths in excess of ISO feet. $2-Million NSSC Contract Awarded Fairbanks Morse The Naval Ship Systems Command has award-ed a negotiated fixed-price, multi-year contract worth $2,008,246 to Fairbanks Morse Inc. of Beloit, Wis. The contract (N00024-69-C-5259) is for diesel engines, associated special tools, and engineering services. MULTI-PURPOSE CARRIER, the Frans Malmros, was con-structed by Hitachi Zosen's Innoshima shipyard for Malmros Rederi A.B. The 870-foot, 108,000-dwt ship is designed to carry iron ore, coal, grain, etc., or liquid cargoes. The 19,000-shp steam-turbine propulsion plant gave the ship a trial speed of 16.6 knots. The ship is outfitted with o gymnasium and swimming pool for the crew. The Frans Malmros is classed by Norske Veritas. 46 Maritime Reporter/Engineering News
