Gus Ruetenik Promoted To Environmental Products Manager At Seaward Seaward International, Inc. of Falls Church, Va., recently an- nounced the promotion of Gus Ruetenik to the position of envi- ronmental products manager. Gus Ruetenik In his new capacity, Mr. Ruete- nik will have overall business re- sponsibility for Seaward Inter- national's environmental products. These responsibilities include sales and marketing, administration, equipment design and engineer- ing, liaison with production, and product promotion activities of the company. Mr. Ruetenik is a graduate of the University of New Hampshire with a B.S. degree in mechanical engineering and a minor in ocean engineering. He joined Seaward International in 1977 as an ocean engineer and was project engi- neer prior to his promotion. Seaward International's pollu- tion control products include the SEA FENCE oil containment boom. Mr. Ruetenik was instru- mental in the design and initial production of the SEA FENCE, which was originally designed for the U.S. Navy. Seaward also man- ufactures the SLURP, floating weir-type oil skimmer, and SEA CUSHION® foam-filled marine fenders. Information Is Available On Three New Doppler Speed Logs By Raytheon Literature is now available de- scribing three new Doppler speed logs that use bottom-reflected sound to provide accurate speed data from 0.01 knot to 40 knots, from Raytheon Marine Company. The Raytheon Doppler systems track the bottom to depths of 1,000 feet using acoustic beams directed ahead, astern, and to each side of the vessel. In deeper water, the system automatically shifts from bottom-tracking to watermass-tracking. In addition to calculating speed, the Raytheon Doppler speed logs also provide a digital depth display to a maxi- mum of 1,000 feet and can be read in feet, fathoms, or meters. The model DSL-250, simplest in the Raytheon line, is a single- axis, dual-beam system designed for providing continuous accurate speed and depth resolution in the ship's fore/aft axis. In the "normal" operating mode, at speeds less than 9.99 knots, speed is displayed in hundredths of a knot. This ensures that the system will sense movement of as little as one foot per minute when approaching anchorage, moorings, or berths. Other features include an adjustable depth alarm, built- in self-test circuitry, and a me- chanical distance-run log. The model DSL-350 is a dual- axis, dual-beam system for se- lectable resolution of the ship's fore/aft and port/starboard speed. The port/starboard or athwartships speed feature is es- pecially useful in determining set and drift from the steered course. The model DSN-450 is a dual- axis, four-beam sonar navigator that provides continuous, simul- taneous readout of the fore/aft and athwartships speed. On all three models, data is processed for digital display on an easily read 11-inch by 14-inch bridge display/control unit and for input to radars, other ship- board electronic equipment, and integrated navigation systems. Weatherproof digital and analog repeater displays are also avail- able for use in exposed locations.

When bigger barges are built, Wiley will build them. A case in point: Pittston Marine's new tank barge, a floating oil field over 315 feet long was recently built by Wiley. Designed for manned coastwise service or unmanned ocean service, the "Rockland" carries up to 70,000 barrels of Grade A petroleum products and lower, with approximately 3.4 miles of heating coils for hot oil. Deep well pumps are on the deck, with drive engines in an all- weather enclosure. A recessed house for quarters and galley is heated and air-conditioned. The "Rockland" is the latest in the Wiley built deck, tank, dump crane and coal barges; clamshell dredges; tugs and towboats; tankers, passenger and fishing vessels. With Wiley's broad marine capabilities, we can custom-build to your specifications. Wiley's facilities are located in Port Deposit, Maryland.
