The naval architect behind the design of the Windflex-27 crew transfer vessel has confirmed that the first examples of the type are to be delivered to German and Irish owners
Vessel designer and naval architect Incat Crowther confirmed that the first two Windflex-27 crew transfer vessels (CTVs) built by Penguin Shipyard in Singapore are to be acquired by Germany-based Opus Marine.
To be named Valkyrie and Wotan, the vessels are to be delivered to Opus Marine shortly and will start working with Ørsted in Taiwan.
Incat Crowther also confirmed that four more vessels based on the Windflex-27 design are under construction. Two of the CTVs based on the design are under construction for another CTV owner - Dublin, Ireland-based Farra Marine, which recently confirmed a second vessel with Penguin Shipyard.
Both vessels for Farra Marine will be delivered in Q1 2022. The first vessel, ordered in 2020, is already nearing completion.
While the Farra Marine CTVs share the same propulsion as Valkyrie and Wotan, they have been extensively customised to meet the client’s unique requirements. The design is also suitable for multiple propulsion options as well as parallel hybrid integration.
The remaining two Windflex-27s being built at Penguin shipyard are currently available for sale.
The Windflex-27 is part of Incat Crowther’s ‘Sea Sherpa’ design portfolio. In addition to European flag state compliance, the Sea Sherpa designs are fully compliant with US, Taiwanese 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 27 m by 9 m 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 10-ft containers or 2 x 20-ft and is equipped with a deck crane. The aft deck can accommodate a 10-ft container. Both decks feature multiple tie-down points for flexibility, and to accommodate 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 people in comfortable business-class seats.
The upper deck features an elevated wheelhouse with excellent views over the bow for safe transfer operations. Behind the wheelhouse is a crew space with mess, bathroom and twin cabin.
The twin hulls have two single crew cabins per side and bathrooms. All accommodation is MLC-compliant.
The designs all benefit from Incat Crowther’s resilient bow technology, a bow fendering system designed to maximise vessel wave-height transfer capability while minimising impact loads.
Valkyrie and Wotan are powered by quad Scania DI16 077M, with each engine producing 662 kW. Propulsion is via quad Hamilton 521 waterjets, enabling the vessel to achieve speeds of up to 30 knots. The waterjets utilise Hamilton’s JETanchor system fitted as standard, offering excellent station-keeping characteristics.
