Energy-Saving Tanker 'Manitou' Delivered By Lindenau Shipyard The Paul Lindenau Shipyard in Kiel, West Germany, recently deliv- ered the energy-saving, IMO Type II oil/chemical tanker Manitou (photo) to Atlantic-Rhederei F. & W. Joch of Hamburg. This special- ized tanker is the fourth of a series that the Lindenau yard developed together with the shipping compa- ny. Built for worldwide trading and classed by Germanischer Lloyd, the Manitou has an overall length of 380 feet, beam of 51.8 feet, depth to main deck of 30.5 feet, and draft on summer freeboard of 23.5 feet. Main propulsion is provided by an MaK 6M551AK diesel engine with a maximum output of 3,500 bhp at 375 rpm. Service speed is 14 knots. A schottel bow thruster is installed for enhanced maneuvera- bility. Electrical power is produced MULTI-PURPOSE PUMPING EFFICIENCY VM BILGEMATE Ideal for pumping bilges—stripping ballast, etc. Peripheral jet design handles liquids, solids, air. 2'//' to 6" sizes available.

The vessel has two oil-fired boil- ers, and an exhaust-heat boiler that is used for preheating the heavy fuel oil, and heating water and accom- modations. Under favorable condi- tions (high outside temperature), part of the exhaust-heat energy can also be used to heat the cargo. The vessel meets the MARPOL Convention Annex I for oil emis- sions and Annex II for chemical emissions, and IMO resolutions for the control of discharge of tank- washing water and ballast water from the cargo hold area. The Manitou is equipped with a free-fall lifeboat for 26 persons. She is said to be the first oil/chemical tanker authorized to have such a lifeboat. Two inflatable liferafts are also provided, each with a capacity for 20 persons. Ingalls Awarded Over $145 Million In Navy Contracts Ingalls Shipbuilding Division, Litton Industries, Inc. (Ingalls), Pascagoula, Miss., was recently awarded a $129.5-million Navy con- tract for acquisition of standard equipment and services for the 14th, 15th and 16th Ticonderoga (CG-47) guided missile cruisers. In addition, Ingalls also has been awarded a $15.9-million Navy con- tract for the regular overhaul of the submarine tender USS Simon Lake (AS-33). The ship was built in the Puget Sound Naval Shipyard, Washington, and was commissioned in November 1964. Her sister ship, USS Canopus (AS-34), was con- structed by the Mississippi-based shipyard and delivered to the Navy in November 1965. by three diesel-driven generators and a shaft generator. Due to the optimal lines of the hull and the internationally patent- ed Lindenau bulbous bow, 20 per- cent less propulsion power is re- quired for this vessel compared with other oil/chemical tankers with the same draft and deadweight. The double hull construction en- closing the cargo tanks reduces the amount of energy needed to heat the cargo due to the isolated air layer. Cargo piping and heating coils are of stainless steel. All cargo tanks are coated with Camrex Camcote epoxy. Further advantages include the easy cleaning of the tanks and quicker unloading due to the slanted form of the tank bottoms. Electronic equipment includes two Decca radars, Decca Navigator, Anschutz gyrocompass and gyropi- Circle 200 on Reader Service Card Alfa-Laval Introduces Nirex Distiller For Smaller Vessels Alfa-Laval, Inc.. Fort Lee, N.J., has introduced a new Nirex fresh- water distiller designed to meet the needs of smaller vessels. Designated the -JWP-26-C, the unit is a smaller version of the -JWP-36-C series. The unit can be used on fishing vessels, work boats, supply boats and off- shore rigs with small engines as well as vessels in excess of 2,000 dwt. The JWP-26-C has a capacity range from 300 to 5,500 gpd, de- pending on the heating medium and cooling water temperatures. Distill- ers can be dimensioned to suit any jacket water temperature from 131- 194°F, and any sea water tempera- ture required. The quantity of fresh water produced can be altered with- in each size by varying the number of plates in the heat exchanger as- semblies. Weighing no more than 1,140 pounds, the unit can be dismantled easily. This allows for the subassem- blies to be hand carried by two per- sons into the engine room without making any alterations in the room. The JWP-26-C can quickly be reas- sembled—just bolt it together, hook it up to water and electrical lines, and start it up with a push of a but- ton. The distiller comes with its own pumps, electric motors, control pan- el, salinometer and internal piping. The distiller is designed to oper- ate automatically under varying operating conditions. The freshwat- er salinity is monitored by a salinity indicating system with an automatic dump valve. The standard distiller delivers a constant salinity of no more than 1.5 ppm, what is said to be the lowest of any available on the market. On sensing an excessive salt content (2 ppm), the fresh water produced is automatically diverted to bilge by the dump valve. Like all Alfa-Laval Nirex distill- ers, the JWP-26-C series features titanium plate heat exchangers which eliminate corrosion problems The Nirex distiller, model JWP-26-C80, with cover removed for plate heat exchanger inspection. and allow for increasing capacity simply by installing additional plates in both the condenser and evaporator. To further eliminate corrosion, the distiller cover is pressed from stainless steel; non- ferrous alternatives are also avail- able. After cleaning, normally required only once per year, the Nirex distill- er delivers 100 percent capacity. The "C" in the designation refers to the combined condenser cooling and ejector water system, a key feature of the JWP-26-C. This combined system lowers installation costs and increases reliability of the distiller. According to Bill Huffman, Alfa-Laval product manager-Nirex, more than 50 units have been sold worldwide since May 1984, includ- ing 12 units installed on board French fishing trawlers. Alfa-Laval is a worldwide group offering services to marine and land-based operators in more than 125 countries. A complete line of purifiers, plate heat exchangers, and energy-saving, reliable freshwater distillers is available.
