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.

ESNA is the inventor and designer of the Sea Puffin SES Daughter Craft. In addition to providing the design package, they have also supplied the air cushion systems to Sea Puffin 1. This includes the state-of-the-art ESNA air cushion motion damping systems. With this system the captain can govern the vessel's motions by an intuitive touch screen.
ESNA is an independent ship design company for high-performance vessels. We specialize on air cushioned catamaran/Surface Effect Ships (SES), where we have unique world-leading competence. Our strategy is to complement yards with design packages and the special air cushion systems and equipment, allowing any yard to build safe, cost efficient and reliable Surface Effect Ships.
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.
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.
WindPartner AS, owner and manager of Sea Puffin 1, and ESNA AS, the designer of Sea Puffin 1, are pleased to announce that Sea Puffin 1 recently conducted successful transit and push-on trials at the Horns Rev 1 wind farm off Denmark with a significant wave height of 1.5 m and has demonstrated record low fuel consumption (<100 ltr/hr !) , all in accordance with expectations.
WindPartner AS, a company based in Kristiansand Norway, has entered into newbuilding contract with Esbjerg Shipyard A/S (Denmark) for the construction of a new designed daughter craft for personnel transport between mother vessel and offshore wind turbines for offshore wind farm service and maintenance work. The vessel can also be used as a small CTV for near shore offshore windfarms.
Built by Denmark’s Esbjerg Shipyard to an ESNA design, Sea Puffin 1 is the first of a new generation of high-performance daughter craft based on surface effect ship (SES) technology.
Det Kristiansandsbaserte selskapet WindPartner AS har tatt levering av verdens første Daughter Craft / CTV basert på luftputeteknologi (SES) fra Esbjerg Shipyards A/S, i Esbjerg / Danmark.
WindPartner har fått levert sitt første, lille servicefartøy for offshore vindparker. Flere lokale næringslivfolk satser penger på selskapet.
The world’s first daughter craft based on surface-effect-ship (SES) technology, supported by the Carbon Trust’s Offshore Wind Accelerator (OWA), has kicked off two months of sea trials at Vattenfall’s Horns Rev 1 and Ørsted’s Horns Rev 2 wind farms.
