The series 8000 is the biggest and most powerful engine family of MTU, rated up to 9.100 kW. It is mainly intended for main propulsion of fast military and commercial vessels. Recently, MTU added a new member to this engine family, the 'gas protected engine'. Such engines have to be able to operate safely even in an environment that could be contaminated with explosive gases! This engine has been designed for the propulsion system of the new and the world's most powerful emergency tugboat, the 'Nordsee'. The 'Nordsee' is currently under construction and will be operating from the beginning of 2011 in the Northern Sea. Equipped with two series 8000 engines it will have 200 to bollard pull capability and a maximum speed of more than 19,5 knots. Furthermore, the gas protected version of the series 8000 engines will make it able to operate in hazardous and explosive environments. MTU was awarded the contract for this boat from the 'German Coast Guard Working Group' (Arbeitsgemeinschaft Kuestenschutz) after a Europe-wide invitation to tender from the German Federal Ministry for Transport, Building and Urban Affairs (Bundesministerium fuer Verkehr, Bau und Stadtentwicklung), because MTU is the only engine manufacturer in the world that has a long-term experience with this special technology. In the last decades, several similar boats have been equipped with smaller gas-protected MTU engines of series 396 and series 4000. Giving a series 8000 engine these special capabilities allow shipbuilders to provide faster and more powerful emergency tug boats and therefore increase the safety on sea. In mid 2009, MTU completed this development project successfully and received the final certificate from 'Germanischer Lloyd' for this engine. This presentation highlights the challenges of this special application as well as the technical solutions applied. The unique capabilities of the series 8000 engine in this application are given. The safety concept of the engine and the electronic engine control system is also shown.
