Low Loss Hybrid Energy System

Posted by Irina Tabakina

Wärtsilä launched its new Low Loss Hybrid (LLH) innovation at ONS 2014. The Wärtsilä LLH uses different power sources in combination with energy storage devices to operate the prime movers closest to their optimum performance. In addition to annual fuel savings of up to 15%, depending on the type and configuration of the engine and mission profile, the LLH ensures a substantial reduction in exhaust gas emissions, the manufacturer said.
The Wärtsilä LLH was earlier this year installed and tested aboard the Platform Supply Vessel Viking Lady. A comprehensive measurement program that monitored transit mode in heavy weather conditions, critical operations, and standby mode confirmed actual fuel savings of 15%. For this particular vessel, such savings would give an estimated payback time of less than four years. Emission reductions were also substantial, with local emissions in harbor virtually eliminated.
