Norwegian builder secures orders for two CSOVs

Norwegian shipbuilder Vard has entered into an agreement with an international customer for the design and construction of two commissioning service operation vessels (CSOVs), with an option for a third vessel.

The vessels will be designed by Vard Design and will be intended for offshore wind farm operations. Vard said the design has been customised to the customer’s needs to give environmental benefits, featuring a hull optimised for low fuel consumption, high operability and onboard comfort.

The hybrid battery propulsion system will allow for periods of zero local-emission operation, provide additional peak power when required, and ensure an energy-efficient profile across all activities.

The vessels will also be prepared for future methanol operation.

The CSOVs will each be equipped with a 30-metre electric controlled motion compensated (ECMC) walk-to-work gangway system from Vard subsidiary Seaonics. Each gangway will include an integrated tower and lift and will enable stepless access for technicians to offshore installations positioned between 15 and 30 metres above sea level.

In addition, each vessel will be fitted with a seven-ton ECMC 3D-compensated crane capable of lifting up to five tons at a reach of 25 metres.

Each CSOV will measure approximately 87 by 19.5 metres and will have accommodation for up to 120 personnel in 84 cabins.

The vessels will be equipped with DP2 positioning and seakeeping systems as well as hybrid propulsion systems capable of delivering a maximum transit speed of 13 knots.
