Hitachi Zosen To Sell Kyushu Shipbuilding Plant Industry sources recently dis- closed that Hitachi Zosen Corp. plans to sell its major shipbuilding plant on the southern Japanese is- land of Kyushu for about 40 billion yen (128 yen equal US$1). It was also reported that Hitachi Zosen will operate the dockyard on a lease-back basis from the affiliate. The plant has an annual shipbuild- ing capacity of 250,000 gross tons. PROPULSION UPDATE Iti a lifesaver for your engines. ^ The Spinner II® lube-oil centrifuge cuts engine wear in half. Removing dirt from your engine's lubrication system is the key to reducing engine wear and lowering your maintenance costs. That's what the Spinner II centrifuge does, efficiently and economically. Typical full-flow lube-oil filters trap dirt particles down to only about 40 microns in size. However, parts like piston rings can squeeze the oil film as thin as one micron. Remove the microscopic particles and you can reduce engine wear by half or better. To do that requires a centrifuge. Until now, a centrifuge meant investing in an expensive, electric-motor-driven machine. Now there's the Spinner II cen- trifuge, a self-contained, high-speed unit driven only by oil pressure. It removes abrasive grit as small as one-tenth of a micron for a low cost you can justify! The complete line of Spinner II centrifuges protects all marine diesel engines.

Schottel Offers Free Color Brochure On Its 'Rudderpropeller,' And Units For Shallow-Draft Propulsion Schottel, a leader in propulsion technology, has published a 20- page, full-color brochure on the pro- pulsion units marketed by the com- pany. The Schottel Rudderpropeller, the heart of the system, is a com- bined propulsion and steering unit. The engine power is transmitted through bevel gear sets to the pro- peller. In addition, the propeller can be rotated through 360 degrees to provide steering, so that full thrust is available in any direction. This system has been used worldwide for more than 35 years, providing maxi- mum maneuverability with full power for ahead and astern. The units currently available range from 15 kw to 5,000 kw (20 hp to 7,000 hp). Schottel Rudderpropellers are in service for main propulsion, propul- sion assistance and dynamic posi- tioning in all fields of shipping. A joint venture of Schottel and Lips United B.V. was founded in 1981 for the marketing of large thrusters for oceangoing vessels. This company, in The Hague, is named Schottel-Lips B.V. Schottel- Lips thrusters are constructed of standard components, such as up- per and lower gearbox, stem section and steering gear, to suit a custom- er's specific requirements. The heart of the system—the Rudderpropeller—may be fitted steerable or non-steerable, retract- able or nonretractable, for vertical or horizontal drive and with fixed or controllable pitch propellers. To meet the increasing demand of shallow-draft propulsion units for navigation on rivers and canals, nor- mally not navigable, special jet pro- pulsion units have been developed. The units are capable of operating The Schottel Rudderpropeller, "The heart of the system," is a combined propulsion and steering unit. at low drafts with full thrust and optimum efficiency. The following jet propulsion sys- tems are available: Schottel Cone- Jets, developed as a main drive or as a bow maneuvering aid for extreme- ly shallow-draft vessels; Schottel Pump-Jets, in which the propeller is replaced by a specially designed pump wheel with optimized effi- ciency; and Schottel Bow-Jets which work with a horizontal pro- peller sucking water from below. The Schottel Rudderpropeller is detailed in a free 20-page color bro- chure. The publication contains more than two dozen photographs of the system and other Schottel products.

Expands CADAM To Portsmouth Location JJH Inc., a leading naval engi- neering organization with facilities located in Crystal City, Va., Ports- mouth, Va., Cherry Hill, N.J., Bath, Maine, Panama City, Fla., and Long Beach, Calif., recently announced the expansion of their CADAM ca- pability to their Portsmouth facili- ty. JJH Inc. has installed and is using the CADAM® graphics system sup- ported by a Perkin & Elmer 3210 computer with eight megabyte memory, magnetic tape drive, high- speed printer, electrostatic plotter, and system console. The graphic workstations utilized by JJH Inc. personnel allows for the continued development of an existing data base stored on 80 and 300 megabyte disc drives. The CADAM system is equipped with telecommunications which provide continuous electronic access to detail drawings and mate- rial lists during design develop- ment. The CADAM system employed by JJH Inc. at Portsmouth is one of the most cost-effective tools avail- able in support of service to the marine industry and provides such benefits as increased design produc- tivity, shorter design lead time, im- proved engineering change control, standardization of design and the support of shorter production schedules.
