Tier III genset
The German based Rolls-Royce brand MTU and Fairplay Towage are to test an MTU diesel genset with SCR exhaust aftertreatment in a harbour tug in order to verify compliance with IMO Tier III emission requirements that come into force as of 2016. The nitrogen oxide (NOx) emissions will be cut by 90% compared with the IMO Tier I regulation that was introduced in 2000.
“This is one of the world’s first tests of high-speed diesel engines equipped with an SCR system designed to meet the NOx levels required by IMO Tier III,” said Dr. Michael Haidinger, Chief Sales Officer of Rolls-Royce Power Systems. “We are proud to have this opportunity to demonstrate to our customers a pre-series and cost-saving solution.”
The new Fairplay tug with a bollard pull of 90 tons is currently being built at the Spanish shipyard Astilleros Armon and is scheduled to go into service in the Port of Rotterdam as of 2015.
MTU is supplying the two main 16V 4000 M63L propulsion engines, each delivering 2,000 kW, a 16-cylinder 4000 M23F diesel genset rated at 1,520 kW, and the SCR system. The exhaust aftertreatment system, with selective catalytic reduction (SCR) technology, is connected to the diesel genset. As with modern commercial vehicle drive systems, an aqueous urea solution reacts with the nitrogen oxides in the exhaust gas to neutralise them.
Fairplay Towage with its registered office in Hamburg operates a fleet of around 40 ships in Europe.
