Remanufactured Engine for Rhenus Schub I
Wärtsilä replaced one of the heavily damaged main engines of the push boat Rhenus Schub I by a remanufactured engine. Rhenus PartnerShip, one of the first shipping companies of dry cargo in Europe, wanted to replace the crankshaft damaged engine by the same type of engine with a CCR2 certificate to qualify for a subsidy.
The remanufactured Wärtsilä D628 was placed in the Rhenus Schub I in Schiedam (the Netherlands). The delivery time from order to replacement including the removal and installation came to four weeks in total. “Wärtsilä was able to provide a Wärtsilä D628 that met our needs. We wanted a similar engine back into the ship that would meet the latest environmental requirements”, says Ralf Deutsch, head of technical services at Rhenus PartnerShip. After a successful trial the Rhenus Schub I is ready to operate again.
The Wärtsilä Deutz SBV8M628 (Wärtsilä D628) is no longer produced and therefore Rhenus PartnerShip decided to go for a remanufactured Wärtsilä engine. This engine meets all requirements and can be placed in the existing engine room. With this as good as new engine the pushboat will be able to operate another twenty to thirty years with an expected fuel reduction of 7%.
Due to the energy efficiency of a remanufactured engine barge men in the Netherlands can qualify for subsidy. In the Netherlands this is governed by the so-called energy investment rebate (EIA). To qualify for subsidy in Germany the ‘new’ or remanufactured engine should be below 30% of the fine dust limit (0.2 g / kWh).
