Damen Shiprepair Oranjewerf has bid farewell to VOS Start, Vroon BV’s first DP2, subsea-support, walk-to-work (W2W) vessel.
VOS Start’s first project will be a charter to MHI Vestas Offshore Wind for the construction of the Walney Extension Offshore Wind Farm in the Irish Sea. There she will provide logistics support, accommodation and W2W capability.
The 80 metre VOS Start arrived at Oranjewerf on 1 June from her build yard in China for the installation of a motion-compensated gangway system – the first of its kind – by Barge Master and Bosch Rexroth, the extended installation of a Kongsberg reference system (including a ‘windfarm module’) and an active heave-compensated crane from SMST. In the eight weeks that she was in the yard, the vessel also underwent a wide range of other upgrades and preparations for her first charter.
The VOS Start is the fourth in a series of new vessels for Vroon that they have brought to Oranjewerf for finishing off following their initial build in China. However, this is the first time that Damen Shiprepair Oranjewerf and Vroon have worked together on a W2W vessel and, with Barge Master and SMST both Dutch companies, it was logical to do the final installations in the Netherlands with all the necessary expertise and support close by. Other local specialist suppliers also contributed to what has been, owing to the W2W element, the most complex upgrade yet for a VOS subsea support vessel at Oranjewerf.
Expertise on Dutch turf
These specialists included Niron Staal Amsterdam, another member of the Damen Shipyards Group, which fabricated two boat landing ladders which were then installed by Oranjewerf. Other equipment installed include a Lightweight Taut Wire, Radius and a Hipap position reference system, all manufactured by Kongsberg. The mountings necessary for up to eight temporary living units, supplied by H2M, were also fitted, along with many other modifications.
Jeen van der Werf, Commercial Manager at Damen Shiprepair Oranjewerf said: ‘… Oranjewerf is particularly well-suited for this project, due not just to the capabilities of its workforce, but also to the extensive craneage on its berths and space on the quays for the largest mobile cranes.’ The VOS Start was also placed in Oranjewerf’s 135 metre floating dock for a period to allow the installation of the boat landings.
A key element in the success of this project was the excellent cooperation between Damen Shiprepair Oranjewerf and Vroon Group BV / Vroon Offshore Services, represented on-site by senior newbuilding superintendent Foppe Molenaar.
