Service Operations Vessel at a glance
More access, more safety, more comfort

Accommodation for up to 45 turbine maintenance personnel and 15 crew. As an option this can be increased to 90 POB.

The hull requires less installed power than a conventional PSV thanks to its symmetrical wind profile and efficient four split switchboard system.

Helicopter deck
This helicopter deck arrangement results in an increased operability of the helicopter offshore. Besides that it provides additional means of gaining access to an offshore structure.

The bow section has been lowered to create a V-shape. This offers significantly reduced slamming, facilities inclusion and improved operation of the bow thrusters.

Daughter craft
The daughter craft is used as a means of transferring people to the offshore structure in favorable weather circumstances

Safe working area
Due to the design of the bulwarks direct access to and from the deck area is arranged

The primary access system is a motion compensated gangway.

Command & Control
The bridge and site management are included in one deck house

The vessel features a diesel electric main propulsion, increasingly favoured in the offshore market, driving twin azimuthing stern thrusters.

Deck space
A total deckspace of 470 m² including workshops and an extensive sheltered area

Crew transfer
Access has been provided for those boarding and disembarking the SOV via a crew transfer vessel.

The strong V-shape in the frames in the aft ship reduce slamming occurrence, while the concentration of volume in the mid ship region achieve a slender aft. Both features make stern to weather operations more comfortable than on a common PSV.

Covered container storage
In addition to the on-deck storage space, the SOV features a covered container storage area aft for turbine equipment.

The SOV features an active heave compensation crane with a 2 tonne lifting capacity at 27.5 m

The elevator has been located close to the motion-compensated gangway. This is just one of a series of features implemented in the vessel design to ensure a smooth flow of personnel and equipment for optimal workability.
