ÅLESUND, Norway — VARD will construct two commissioning service operation vessels (CSOVs) for UK-headquartered Purus Wind, with an option for two further vessels.
The CSOVs are of the VARD 4 19 design and have been upgraded in cooperation with Purus Wind to achieve a hull design optimized for low fuel consumption and resistance.
Their battery hybrid system allows the vessels at times to operate with zero emissions, VARD claimed. They are prepared for charging at sea and can be connected to the power grid in the wind farm or harbor to charge batteries regularly without the need to go ashore.
And the design also accommodates future operation on methanol.
The vessels will feature SEAONICS’ Electric Controlled Motion Compensated crane, designed to maintain the load close to the crane tip from the deck level to the TP platform, allowing for fast and safe cargo transfer, VARD said.
The stepless walk-to-work-system is able to work with stepless access in a range from 15 to 30 m above sea and is suitable for both personnel and cargo transfer.
