Propulsion Update MTlTs 595 Diesel Series Design Concept Proven Aboard Ferry 'Deutschland' MTU Friedrichshafen installed its first 12V 595 series diesel engine aboard the 476-foot ferry Deut- schland in October of 1990. This model is rated at 2,100 kw at 1,500 rpm and replaced one of the ship's nine 1,840-kw, 12-cylinder MTU 956s. The engine has had over 4,000 operating hours with a reported pow- er level of 83 percent and a 95 percent share of the ship's service time. An MCS computer monitoring system, developed by MTU-Elektronik, was installed in order to gather data about the engine when installed aboard a ship. The conclusions gath- ered from the data taken show that the engine is easy to maintain and should have low life-cycle costs. A split-circuit cooling system (TE concept), originally introduced with the 396 series, was also installed on the 595 series engine. MTU has also been recording test results from a trial engine which was mounted on a factory test stand. The engine has reported logged 3,000 hours without any notable malfunc- tions. Based on a power output of 3,240 kw at 1,800 rpm, MTU says the average utilization rate is about 90 percent.

When an angry sea turns into towering mountains of water, the last thing you want to doubt is your Emergency Position Indicating Radio Beacon (EPIRB). ACR leaves no doubt. From recreational to commercial beacons, every ACR unit has to meet our own rigid stan- dards before it goes to sea. Standards that exceed those of worldwide marine authorities. That's why ACR is the most-selected EPIRB for commercial, military and recreational vessels throughout the world. But there's another, more important reason for having ACR EPIRBs aboard: They've saved more lives than all the others com- bined. Period. ® ACR Electronics, Inc.
