THE SAFEST ACCESS TO WIND TURBINES COMBINED WITH THE HIGHEST STANDARDS OF LIVING AT SEA

WaveMaster 1 is unique as a purpose-built vessel for the deployment and retention of offshore support and maintenance engineers. Its development has been driven by functional requirements, based on feedback from potential end-users. WaveMaster 1 has on-site work and storage facilities plus accommodation for up to 70 maintenance personnel, management and a crew of 20. It will be able to stay out at sea for voyages of up to one month and feature dynamic positioning (DP2). Crucially, it will be equipped with a motion-compensated transfer gangway to allow maintenance personnel to walk between vessel and offshore structure.
Work Safe, Live Safe
Keeping in mind the everyday tasks performed onboard, Damen has created a concept that will benefit both crew members and vessel operators.

Proven technology
WaveMaster 1is able to achieve safe and comfortable access up to 80% of the time, including worst case scenarios, in the Central North Sea.

MOTION
A monohull form has been selected to minimise accelerations caused by roll motions, reflecting considerations the SOV will be on DP 80 % of the time at speeds between 0-5 knots.
SEAKEEPING
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. 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.
EFFICIENCY
The hull requires less installed power than a conventional PSV thanks to its symmetrical wind profile and efficient four split switchboard system. The four split main switchboard ensures an efficient generator distribution offering more power in the event of a single switchboard failure.
SAFE TRANSFER
The primary solution is a motion compensated access gangway system mounted on the port side. Its managing software is aligned with the vessel’s DP system to accommodate gangway motion limits. For a high level of redundancy alternative transfer methods are included, including helicopter access and a daughter craft.
LOGISTICS
All internal spaces have been designed with logistical or personnel flow in mind. Spaces used for work and accommodation on board should be optimised for reasons of efficiency. A well routed work flow supports an improved working environment yet preserves a high convenience level.
COMFORT
Accommodation areas are located amidships to minimise vertical accelerations (15 % below a conventional PSV). The vessel accommodates engineers whose previous experience may be land-based. Avoidance of seasickness and perception of a comfortable working environment will influence their acceptance of extended stays at sea.
