Penguin Shipyard in Singapore is building a 27-meter catamaran wind farm service vessel for Farra Marine, the Irish operator’s first. Construction commenced in September, and the vessel, named Farra Orla, is expected to be delivered in the second quarter of 2021.

The vessel is the third in Penguin’s Windflex 27 series, which designer Incat Crowther says offers excellent speed, deadweight and seakeeping, making it capable of many roles in the offshore wind industry.

The vessel has a deadweight above 50 tonnes and features two working decks. A large working deck forward is equipped with a deck crane can accommodate up to four 10-foot containers or two 20-foot. The aft deck can accommodate a 10-foot container. Both decks have 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 24 personnel in comfortable suspended seats.

The upper deck features an elevated wheelhouse with commanding views over the bow, for safe transfer operations, behind which is a crew space with a mess, bathroom, and food preparation space.

The hulls feature two single crew cabins per side and bathrooms.

The Incat Crowther 27 is powered by quad Scania DI16 077M, each producing 662kW. Propulsion is via quad Hamilton 521 waterjets. It will have an operating speed of over 25 knots.

The design complies with European regulations for transferring 24 offshore workers and will be classed with Bureau Veritas. It will be the first of a new generation of offshore support vessels, able to stay at sea longer, work in increased weather limits and provide the greatest safety and comfort for those onboard.
