Wärtsilä HY Mechanic

Wärtsilä has introduced the marine sector’s first hybrid power module that combines en­gines an energy storage system and power elec­tronics with a newly developed energy manage­ment system (EMS).

The Wärtsilä HY hybrid propulsion system is expected to become the norm for ships over the next decade lowering fuel consumption re­ducing emissions and improving vessel perfor­mance. The new system has a “Green Mode” to reach zero emissions and smokeless operation is also possible with a patent pending automation procedure. In addition fewer engine operating hours lower the need for maintenance.

Lloyds Register a maritime classification so­ciety has issued an Approval in Principle cer­tificate to the power module based on technical material and safety analyses in normal operation.

The Wärtsilä HY will be available first for tugs and medium sized ferries but the company plans to design for other types of vessels in the coming years. The equipment was officially launched during the Nor-Shipping conference in Oslo Norway.
