New types of engine
Today, owners are looking for new ways to improve their power systems so that they cost less to operate and are more environmentally friendly. One solution that many operators are considering is the adding of a battery or energy storage system to provide hybrid power to meet a vessel’s needs. Such a solution is proving popular in delivering important reductions in fuel costs and meeting the latest emission targets.
Vessels energy storage systems
For instance, Canadian-based Corvus Energy uses a lithium ion based energy storage system that has been approved by class societies DNV GL, Lloyd’s Register and ABS. In addition, the industry is seeing an increasing number of customers and is requiring vessels to operate meeting latest in emission controls, as a result, growing interest by vessel operators in hybrid solutions to meet growing demand.
In Europe, we are seeing an increasing number offshore support vessels being retrofitted energy storage systems that replace an existing generator. Such an example is the Eidesvik offshore support vessel Viking Princess, which Wärtsilä retrofitted with a Corvus Orca energy storage system in 2017. At the time, Wärtsilä said the adoption of energy storage systems could result in fuel savings of up to 30% and a reduction of CO2 emissions by up to 18% a year.
