Europe’s first inland ship controlled by a rapid mtu Series 4000 gas motor has gone into operations on Lake Constance in Germany.
The ship, which was recently named ‘Richmond‘, will cross Lake Constance eight to nine times each day, conveying up to 700 travelers and 64 vehicles from Meersburg to Constance and back. It joins an armada of five different ships that are totally fueled by mtu engines.
The Richmond is the first inland ship in the world to be controlled by fast, gas-only engines. The two eight-chamber mtu Series 4000 motors each give 746 kilowatts of force and work with less commotion and vibration than a diesel motor, while keeping outflows underneath the ongoing IMO III nitrogen oxide limits, even without fumes gas aftertreatment.
A multipoint gas infusion framework guarantees dynamic speed increase conduct while the turbocharging framework empowers adequate power saves all through the whole speed range for troublesome driving moves. Later on, the ship administrator desires to run the boat on bio-liquified petroleum gas (LNG) and in this manner be totally environment nonpartisan.
The customers: The crew onboard – including captain Oli Hermann and his colleagues Timo Bakaric and Dieter Ehinger – are already familiar with our mtu engines, from the gas processing and heating and cooling systems to the heat recovery, nitrogen processing and alarm systems.
Despite their experience, Timo and Dieter have been grateful for the support the Rolls-Royce team has provided in getting the new drive system up and running. Both Timo and Dieter already know each other from previous projects, so it worked out well again this time for them.
The Mtu Gas Drive System In Detail: Each of the two engines on board has its own fuel tank, each able to carry up to 18 cubic metres of LNG – enough to keep the ferry running 24 hours a day for a week. The tanks maintain the LNG at a temperature of minus 160 degrees Celsius so that it remains liquid.
When the fuel is needed to power the ship’s drive system, the Gas Processing Unit (GPU) brings it back into a gaseous state before it’s fed through to the two separate engine rooms. Gas Regulation Units (GRUs) then ensure the correct pressure for the gas to enter the engines themselves, thus supplying the energy for the two propellers and the generators.
