The U.S.A.'s Leading Builder Of Rigid Inflatable Boats Blohm + Voss Wins Rebuild Contract From Sea-Land PK Marine To Provide Engineering For Combi-ltig Conversion Design to be ready for bidding by mid-summer PK Marine, Camarillo, Calif, will provide de- sign engineering and shipyard coordination ser- vices to Wilmington Transportation Company of San Pedro, Calif, for the conversion of the tug San Pedro to a combi-tug configuration. This conversion will include the installation of an Aquamaster Rauma azimuthing thruster. Ex- isting focsle accommodations will be down-scaled to accommodate the installation of a Detroit Diesel 8V-149 DDEC engine to drive the thruster. Additional bollard pull will be achieved through the installation of a propeller nozzle and Nautican triple rudder system to replace the existing open propeller and single rudder. Other improve- ments will include enhanced stern fendering, hydraulic stern towing pins, and a quick release towing hook. Paul A. Gow of PK Marine considers the combi-tug conversion to be a cost effective method to bring under-utilized, single screw tugs back into fully productive service. The addition of the thruster achieves enhances the maneuverabil- ity, plus increases the available bollard thrust by the addition of more horsepower. Mr. Gow claims not all single screw tugs are candidates for such extensive modification. This modifica- tion dictates that the boat meet current stability requirements for towline pull. Many single screw tugs have neither the initial stability nor the righting energy to meet the stability require- ments. The addition of the thruster compounds this challenge. PK Marine has performed ongo- ing stability analyses, throughout the prelimi- nary design stages of this project. The design package is expected to be ready for bidding, by West Coast shipyards, by mid summer. For more information on PK Marine, Circle 157 on Reader Service Card ACV conversion to SL31. Work includes forebody modification (A), midbody removal (B) and shaft motor & generator (C). The Repair Division of Blohm + Voss has won a rebuilding contract from U.S. shipping line Sea-Land for rebuilding work on the ships Galveston Bay, Sea-Land and Raleigh Bay. The three container ships are of the Atlantic Class Vessel (ACV) type, and have a volumetric capacity of3,652-TEUs. Each is being shortened by three midship sections (three container lengths)—from 950 feet (289.5 m) to 856 feet (261 m). The three ships are also each being given a new bow structure with greatly improved stream- lining. The Hamburg Shipbuilding Research Institute (HSVA) has been involved in the hy- drodynamic calculations and in the planning of the experimental work. The aim of the rebuild- ing is to make the ships three knots faster, raising the speed from 18 to 21 knots. The increase in speed will also be achieved by apply- ing additional power—about 4,000 kW—to the propeller shaft, produced by a diesel generator and supplied to the drive train via an electric motor and a gear coupled to the propeller shaft. The diesel generator can produce 4,860 kW. When entering and leaving harbor, 1,800 kW of \ power can therefore be supplied at the same time to operate a bow thruster.
