Press Release – Incat Crowther is pleased to announce the sale of the first two WINDFLEX-27 Crew Transfer Vessels built by  Penguin Shipyard, a unit of Singapore-based Penguin International Limited. To be named Valkyrie and Wotan,  the vessels will be delivered to Opus Marine GmbH and will start working with Orsted in Taiwan shortly. 

Built as stock vessels, the WINDFLEX-27 is yet another successful co-operation between Incat Crowther and  Penguin. 

The latest project follows on from the successful joint development of Penguin’s Flex Ferry X, a stock passenger  ferry. 

The WINDFLEX-27 is a development within Incat Crowther’s Sea Sherpa design portfolio. In addition to  European flag state compliance, Incat Crowther’s Sea Sherpa designs are fully compliant with US, Taiwan and  Japanese flag state requirements.  

The WINDFLEX-27 offers excellent speed, deadweight and seakeeping, making them capable of many roles in  the Offshore Wind industry. The design’s 27m by 9m platform sports a deadweight capacity in excess of 50  tonnes, offering considerable versatility in terms of fuel and deck cargo transfer. 

The vessel features two working decks. A large working deck forward can accommodate up to 4 x 10ft  containers or 2 x 20 ft and is equipped with a deck crane. The aft deck can accommodate a 10ft container. Both  decks feature multiple tie-down points for flexibility, accommodating every possible requirement or spares and  equipment.  

Inside the main cabin is a large wet room with multiple showers, toilets and lockers. The main deck passenger  space is large and open, with forward visibility, seating up to 24 personnel in comfortable business class seats.  

The upper deck features an elevated wheelhouse with commanding views over the bow for safe transfer  operations. Behind the wheelhouse is a crew space with mess, bathroom and twin cabin.  

The twin hulls feature 2 single crew cabins per side and bathrooms. All accommodation is MLC compliant.  

The designs all benefit from the use of Incat Crowther’s resilient bow technology (patent pending), a bow  fendering system designed to maximise vessel wave-height transfer capability whilst minimising impact loads.

Valkyrie and Wotan are powered by quad Scania DI16 077M, with each engine producing 662kW. Propulsion is  via quad Hamilton 521 waterjets, enabling the vessel to achieve speeds of up to 30 knots. The waterjets utilize  Hamilton’s JETanchor system fitted as standard, offering excellent station-keeping characteristics.  

At the same time, Incat Crowther can announce that Farra Marine has confirmed their second vessel with  Penguin Shipyard which will be delivered in the first quarter of 2022. The first vessel ordered in 2020 is already  nearing completion. 

While the Farra Marine CTVs share the same propulsion as Valkyrie and Wotan, capitalizing on the WindFlex 27 platform’s flexibility, the former have been extensively customised to meet the client’s unique requirements. 

The design is ready for multiple propulsion options as well as parallel hybrid integration.  Penguin shipyard has a further two WINDFLEX-27s under construction and currently available for sale. SPECIFICATIONS – WINDFLEX-27
