Purus Wind orders eight offshore wind vessels

As part of the contract, Damen Shipyards will build and deliver four Damen Fast Crew Supplier (FCS) 2710 Hybrid and three Damen FCS 3210 Hybrid Crew Transfer Vessels (CTVs) and one 90 meter Construction Service Operation Vessel (CSOV).

While the FCS 3210 and CSOV are equipped to operate with ultra-low emissions, they have also been designed to be upgradeable to methanol fueled engines when the time comes.

The new hybrid FCS 2710 will join the three other hybrids that Purus Wind’s High-Speed ​​​​Transfers has ordered in ladies in the second half of 2022.

The larger FCS 3210 are a new design using the same twin ax hull shape as the hybrid FCS 2710.

As with the new FCS 2710s, a hybrid battery pack is integrated into the design for emission-free sailing. The longer length allows for additional crew and passenger space and makes it more comfortable during operations, Damen said. Space is also reserved for a possible conversion to methanol fuel.

An exhaust after-treatment system is included to ensure the vessels are IMO Tier III compliant.

The FCS 3210 are designed to travel longer distances to serve wind farms further from shore, offering the opportunity to stay at sea longer.

According to Damen, the 90-meter women’s CSOV series will be extremely versatile, able to comfortably carry up to 120 people for up to 30 days.

In addition to the diesel/electric propulsion system and battery arrangement, innovative features include a hull design that is nearly symmetrical fore and aft below the waterline and on which Damen’s DPX drive is mounted. This features four identical powerplant units — two in the front and two in the rear — for high-precision maneuvering and stationkeeping, Damen said.

“Other features include excellent stability due to its design, which is further enhanced by a large anti-roll tank. A motion-compensated gangway and crane also ensure smooth transfers of personnel and equipment. Like the CTVs, it has reserved space for additional battery capacity as needed and is being prepared for both conversion to methanol engines and offshore charging,” the shipbuilder told CSOV.

The new ships are scheduled for delivery between 2024 and early 2027. Financial details were not disclosed.
