Service Operations Vessel (SOV) with Walk to Work access

Service Operations Vessel

The Service Operations Vessel has been designed to provide motion compensated transfers for personnel and equipment with optimum logistic flows for the offshore wind industry. The vessel layout offers a large open workdeck area, a number of sheltered workshops and fully covered storage spaces.

The vessel is specifically designed for high-end seakeeping and comfort levels. The vessel features low power consumption and dynamic positioning characteristics, fully optimised for Baltic, Irish and North Sea areas with a working operability of minimum 80 %.

The vessel is especially suited for:

  • Offshore wind planned and breakdown maintenance
  • Breakdown operations
  • Recovery duties
  • Fire fighting (option)
  • Light diving support (option)

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

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

Hull
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.

Bow
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

Access
The primary access system is a motion compensated gangway.

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

Propulsion
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.

Aft
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.

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

Elevator
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.
