Both the sealedThor-Lube and open water lubricated COMPAC systems last longer, offer lower friction and install faster. And because they're pollution free, the fines and delays imposed on ships with leaking stern tubes are totally eliminated. So, for your next new build or conversion project, callTliordon.You'll prevent pollution, and save money. After all, we swim in the oceans, too. 1.905.335.1440 and reversing system. This summer, the company will install its first commercial computer-based ride control system with an embedded Microsoft Windows operating system. System interconnection will be via fiberoptic cable, and preliminary esti- mates show that the switch from con- ventional copper cable will result in a 40 percent weight savings. Finally, Maritime Dynamics now offers composite trim tabs. The trim tabs — which are proven for controlling pitch and roll — were extensively tested before the first set was even fabricated. The company undertook an extensive stress investigation using finite element analysis. Preliminary estimates predict a 70 percent weight savings over an equivalent steel trim tab.
