20 Maritime Reporter & Engineering News Crowley Dedicates DH Tank Barge Crowley Marine Services has deployed the first dou- ble hull tank barge dedicated to Alaska service. Barge 180-1, which was delivered late last year, will load a cargo of petroleum products in Anchorage early next week. Crowley's tug Sinuk has been assigned to tow the new barge, which is designed to carry both deck cargo and about 12,000 barrels of refined petroleum products. The vessels' primary mission will be to per- form remote site and village deliveries in southwestern and western Alaska. In addition to being double-hulled, Barge 180-1 is equipped with a dual anchoring system, two independ- ent piping systems for handling multiple grades of petroleum products, and coated cargo tanks. The deck cargo area features a containment fence, hydraulic crane and portable cargo ramps. The barge also fea- tures 1,300 ft. of float hose on a reel and a complement of support equipment including oil spill response resources. A skiff aboard the tug Sinuk supports beach landings. Circle 24 on Reader Service Card Horizon Maritime Fleet Grows Horizon Maritime of Houston took delivery of the first of a pair of sister ships as part of a fleet expansion program. The new 2000 hp boats will bring the com- pany fleet to six towboats. Designed to each push a pair of 30,000-barrel 300 x 54 x 13-ft. black oil/asphalt barges the new towboats are powered by twin Cummins KTA38 M1 diesels generating 1,000 hp each at 1800 rpm and turning 76 x 58-in. propellers. The boats will make up to the barges with face wires mounted on a pair of Patterson 40-ton electric deck winches. The 76 x 33 x 9.6-ft. towboats have accom- modation for a crew of six. They have tankage for 30,000 gallons of fuel, 8,000 gallons of potable water, 4,700 gallons of wash water and 1,700 gallons of lube oil. The hulls for both boats were built at Quality Shipyard in Houma, La., with the first boat, MV Gemini, finished out at Main Iron Works also in Houma. The second boat, MV Argo, is being finished out at Sneed Shipyard in Houston, Texas for a May 20 delivery. The boats were built to a Corning Townsend design. Circle 25 on Reader Service Card Pusher Tugs for the Amazon's Barge Trade Over the last two years, MAN B&W Diesel A/S, Denmark has been successful with a total of 19 engine and propulsion package contracts to Brazilian tugboat owners. Ten medium-speed engines, five of type 6L23/30A-F and five of type 8L23/30A-F, were recent- ly selected for a series of single-screw pusher tugs under construction in Brazil, at the yard of Estaleiro Sao Joao. The vessels were ordered by the owner J.F. de Oliveira Navegacao Ltd, Brazil. This new MAN B&W Diesel powered series follows another series of six pusher tugs. These vessels are powered by three single-screw, and three twin-screw propulsion packages, type MAN B&W 8L23/30-FKV, ordered by the Brazilian owner Transportes Bertolini Ltda, Manaus. Both series of tugs will be deployed in the special- ized Amazon inland waterways transport system - based on barges. Soya beans, bauxite and trailers from the inland of Brazil and Bolivia are loaded on barges and pushed via the Amazon river system to Santarém and Belém on the Atlantic coast. In Santarém, the barge cargoes of soya beans and bauxite are transferred to overseas trading, ocean-going cargo vessels for the export markets. The engines for the Oliveira tugs will be operating on Heavy Fuel Oil (IF180) and will be driving FP pro- pellers via reverse/reduction gearboxes. For the Bertolini tugs, also operating on HFO IF180, complete MAN B&W Alpha Propulsion Systems with CP Propellers and Alphatronic Control Systems were chosen.
