NKK Markets New Fuel-

Saving Pielstick Engine

Anew fue^saving Pielstick diesel engine has l^portedly been suc- cessfully demortsirated by NKK

Corp. at its TsurVmi Works in

Japan, and the engine will be installed on a 9,00(ygt RoRo vessel which is currently under construc- tion. The new^ngine, a Pielstick 18PC4-2Byrfas reportedly been upgradedyro 1,800 ps from the con- ventional 1,650 ps, realizing fuel cost reductions of approximately three percei

Developed £h*x)ugh a technical partnership wvHa S.E.M.T. of

France, NKK holdamore than 50 percent of the maiket share in

Japan for the company's marine applications. NKK las also found extensive applications in power generators and espects to expand marketing of tbfe more powerful engine for large/generators, specif- ically in Asian markets.

Tolo's Grid-Lock Features

Increased Strength

Tolo Inc. specializes in providing metallic, composite and bonded sandwich structures and assem- blies for the marine and other industries. The company's new sandwich construction technology, dubbed Grid-Lock, reportedly employs CAD/CAM and CNC man- ufacturing systems to produce structures with strength to weight efficiencies that exceed other cur- rent concepts. Grid-Lock is an innovative method of joining struc- tural components with simple tongue and groove joints, resulting in double-skinned, ribbed-core structures that be tandecl Drased or otherwise fusedf tofSUfer. Y^y creating bond* j^nta ct»i tamed the skyn/cjye highly effecpT^snegf- joints, thereby elim- inatm^the potential for peel or tensile loading of the bond line.

The multi-directional ribbing cre- ates a mechanical lock within the engagements to effectively reduce shear stresses by more than 50 percent during loading conditions.

Additionally, the presence of fillets along the edges of the recesses per- mits a gradual transition of stress- es between the vertical ribs and surface panels.

NEC Acquires New CNC

Machinery

North End Composites (NEC) has recently acquired a new, five- axis Computer Numerically

Controlled (CNC) routing machine.

NEC is a complete modeling, tool- ing and parts fabrication facility for the composites industry. The automated router, which was due for delivery in the first week of

January, is able to carve almost any 3-D shape from a block of material measuring 30 x 15 x 6 ft. (9.1 x 4.5 x 1.8 m). By machining numerous sequential pieces which can then be nested together, there is almost no limit to the size of tool- ing which can be performed.

Traditionally, plug and tool mak- ing has involved extensive hand labor to take a concept from a
