APRIL 13, 2016 — Blount Boats, has delivered the Atlantic Pioneer, America's first U.S. Flagged Crew Transfer Vessel (CTV) from its Warren, RI, shipyard. It will begin service for Atlantic Wind Transfers serving Deep Water Wind's Block Island Wind farm at the end of May.

The 21 meter aluminum vessel was designed by South Boats IOW, Cowes, Isle of Wight, U.K, a pioneer in designing and manufacturing crew transfer vessels that has designed and built approximately 81 crew transfer vessels for the European offshore wind sector servicing wind farms throughout Europe. Blount Boats has held an exclusive licensing agreement with South Boats covering the U.S. offshore wind industry since 2011.

The South Boats' 21m is a twin hulled, all aluminum catamaran, dual certified to USCG Subchapter T (Small Passenger) to carry up to 47 passengers and subchapter L (Offshore Supply Vessel) to carry up to 16 offshore workers.

The propulsion system consists of two MAN V12-1400 hp engines, ZF Marine 3050 Gears, and Hamilton Jet HM571 waterjets. On trials, the vessel exceeded the contractual performance reaching sprint speeds in excess of 30 knots, with the ability to cruise (80% power) at 26 knots when in a light condition.

A Cummins Onan 17 kW generator provides AC power to the air conditioning system, a heating system and small galley. A PTO driven hydraulic system powers a deck crane, fire pump, fuel transfer pump, and a salt water pressure washing system. All other equipment is fed DC power through house batteries.

The vessel was specifically designed to carry up to 12 tons of cargo in the bow and 3 tons of cargo in the stern. The forward and after decks are outfitted with cargo lashing and container sockets. A knuckleboom crane is outfitted onto the bow area.

The bow has a bow boarding/loading platform to allow offshore workers to make the transition from the vessel to the wind turbine. The vessel connects to the turbine base by use of a special bow fendering system. The specified fender is the latest generation in proven fendering systems being installed in the European fleet.

The vessel is capable of making transfers in 1.5 m significant wave heights.

The interior of the deckhouse is outfitted with a head, a small galley area with settee seating, twelve (12) suspension seats, storage lockers, entertainment system, Wi-Fi, and sound absorbing decking. The entire deck house is isolated from the hull with vibration mounts for a quieter and smoother ride to and from the work site.
