Series 4000, ferries, tugs

Test bench no. 131 in Plant 1 in Friedrichshafen: ceremoniously, proud and with great expectations, Andreas Schell, Knut Müller and Andreas Kunz press the green start button. The next generation Series 4000 engine springs into life at the start of its endurance test to the cheers and applause of all those present. “I am very pleased to be here today, because, with this engine, we are launching a new innovative product on the market that fits perfectly into our green and high-tech product strategy,“ said Andreas Schell, CEO of Rolls-Royce Power Systems, and expressed his sincerest thanks to all those involved for their hard work.

This is the start of the next important step for the advanced-design, 16-cylinder Series 4000 diesel engine. When combined with the new MTU SCR system, the engine, which is earmarked for tugs, ferries and supply vessels, will produce 75 per cent less NOX emissions and 65 per cent less particulates by comparison with its predecessor. This means it will comply with the stringent IMO III and EPA Tier 4 emission regulations.

The next step, however, is to demonstrate the long-term durability of the engine characteristics over a period of some 1,400 hours. This includes the endurance run, during which the engine will be operated for around 650 hours with no significant interruption. During this time, tests will be carried out to ensure it meets the requirements of its future applications in terms of output, acceleration behaviour and emissions. “This is an engine that is urgently needed on the market,“ explained Knut Müller, Head of the Marine and Government Business Division at MTU. Sales of the engine will start as early as August, with the first pre-series engines scheduled for delivery to the WETA public transit agency for two new catamarans at the end of 2017. The ferries are to enter into service as of mid-2018 in the San Francisco Bay area, which is subject to special environmental protection regulations.
