Safety &
sustainability

Transferring people and equipment from the vessel to an offshore installation must be performed in the most safest way possible. Offshore crews will be able to literally ‘walk to work’ by using the access bridge making offshore access easy as crossing the street. The most challenging feature of the vessel´s design is the motion compensated crane, which can safely transfer equipment from the vessel onto an offshore installation. Especially the ability to safely compensate for pitching and rolling motions in addition to heave, will be an added value. The motion compensated access system and crane are able to compensate waves up to 2,5 meters.

 

A redundant way of transfer


Daughter craft and FRC

To transfer technicians and cargo to the offshore locations, the Walk to work vessel is equipped with a Daughter Craft and a Fast Rescue Craft as redundant transfer methods. 

The daughter craft is suitable for transferring 8 technicians + 2 crew and 1 ton of cargo. The daughter craft can be launched and recovered in 3,5m Hs. The Daughter Craft is capable to sail from an offshore location to port independently of the Walk to Work vessel. 

Gangway

The Gangway 3.0 is selected as the best suitable
‘walk-to-work system’, in terms of operation speed of the system, simplicity of operation, power consumption and HSEQ, to transfer technicians and cargo safely from the vessel to oshore wind turbine and oshore platforms in waves up to 3,0 metres and wind speed up to 20 m/s (38,8 knots).

The gangway is mounted on an adjustable pedestal, which allows technicians to enter the gangway continuously from several decks on the vessel and enable a horizontal ‘walk-to-work’.

Helicopter

The Walk to Work vessel can be eqquipped with a helideck on the aft of the vessel. This deck is suitable for a AW169 helicopter.


Advantages of aft location:

  • less helideck motions > higher operability
  • away from accommodation > increased safety
  • integrated with ush weatherdeck > larger working area


 

Gas-To-Liquid (GTL), a clean and green fuel 

The Walk to Work vessel can be considered as an environmental friendly support vessel due to features as a low power consumption and low noise thrusters. The vessel is unmatched in energy efficiency and enables considerable fuel saving possibilities. Classified as a Clean Ship the Walk to Work vessel can be marked as a green vessel. The vessel’s autonomy will reduce helicopter flights to offshore locations resulting in substantial savings in terms of costs and emissions. Walk to Work vessel is the first offshore vessel in the world to sail on GTL fuel, a liquid fuel made of natural gas with less emissions than conventional fuels for vessels.

 

Other design principles



Workability

The Walk to Work vessel is designed and optimised for efficient offshore operations. The unique combination of design and functions makes the Walk to Work vessel unmatched in efficiency year round.

Comfort

The Walk to Work vessel is developed for technicians who are not used to sailing. A proven hull shape, special propulsion system and comfortable facilities on board result in a high welfare standard.

Stepless approach

The layout of the vessel has been completely adapted to the workflow of technicians and cargo. An unimpeded flow  guarantees safe movements of materials and personnel.
