Leading Classification Society ClassNK has issued an Approval in Principle (AiP) to Eco Marine Power for the development of a renewable energy system for ships, “Aquarius Marine Renewable Energy with EnergySail”.
Environmental technology is being actively developed in the maritime industry for the realization of a decarbonized society, as the IMO has set out a vision which confirms its commitment to reducing GHG emissions from international shipping and to phasing them out as soon as possible. To contribute to the swift and safe social implementation of these initiatives, ClassNK has been providing safety standards applicable to a variety of new technologies based on knowledge obtained by collaborating with front runners.
“Aquarius Marine Renewable Energy with EnergySail” is a system that utilizes a combination of renewable energy (wind and solar) obtained by a rigid sail and solar panel deployed on the deck. Having received an application from Eco Marine Power, ClassNK confirmed the design’s feasibility based on its Rules for the Survey and Construction of Steel Ships and guidelines for “Wind-Assisted Propulsion Systems for Ships” and “Large-capacity Storage Batteries”, and granted the AiP upon completion.
