Sea Puffin

The Sea Puffin SES daughter craft is an air cushion catamaran designed to be launched and recovered by a standard davit from a mother ship. She uses an air cushion to offer operational wave height similar to larger Crew Transfer catamarans, and uses significantly less fuel oil during all operational phases.

The development and realization of first vessel has been supported by the Offshore Wind Accelerator, ENOVA, RFFAgder, Sørlandets Kompetansefond, Innovation Norway and Skattefunn. She was built in Denmark by Esbjerg Shipyard and went directly into demonstration charter for Vattenfall and Ørsted on Horns Rev 1 and Horns Rev 2.

WindPartner is the owner and operator of the world's first high-performance ESNA SES daughter craft, the Sea Puffin 1. She went into operation in July 2018, and has demonstrated both very low fuel consumption and unique high wave height for turbine access.
WindPartner and ESNA have a long-term cooperation agreement for the Sea Puffin, with the ambition to build a series of this vessel type over the next few years.

About WindPartner:
WindPartner AS is an independent service and package solutions provider to the offshore wind industry, with main business idea to build, own and operate new and right-performance DC/CTV by use of SES technology with optimum efficiency and workability compared to both existing standard DC’s and CTV’s. WindPartner has a flexible business model for the Sea Puffin, ranging from lease/time charter (preferred), purchase/sale and combinations of these.
