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.
