Kooiman completes conversion of DP2 support vessel Zwerver I

Kooiman Marine Group has converted the work vessel Anna-B into multi-purpose DP2 support vessel Zwerver I for Van Stee Offshore. Although the shipyard had already designed and built three vessels for the company, this was the first vessel conversion.

Final work on the vessel was completed in June and the vessel is now ready to be deployed.

The average bollard pull of the Zwerver I consists of 66 tonnes with a maximum value of 69 tonnes. The ship is equipped with eight thrusters, two spud poles (Ø 1500 mm), a four/five-point mooring system with an anchor line capacity of 1400 m and a luxurious accommodation for 58 people, including crew. The multi-purpose support vessel is designed to carry out work in tidal areas, such as laying and repairing cables, maintenance work, ROV support and UXO clearance.

‘Ten months ago we commissioned Kooiman Marine Group to convert the work vessel Anna-B in accordance with our ideas and wishes. In fact, only the hull remained intact and roughly 99 per cent of the ship has been completely renovated,’ says Arjan van Stee, owner of Van Stee Offshore (former HvS Dredging Support). ‘During DP trials and commissioning, the ship has demonstrated its capability with great results in a wide variety of configurations. We are therefore proud to expand our fleet with the Zwerver I, both in capacity and in possibilities.’

‘The total conversion of this vessel, with the requirements of Van Stee Offshore in mind, was quite a challenge,’ adds Arjan van der Zegen de Beer, Operational Director Scheepswerf Gebr. Kooiman. ‘Because both the engineering and the conversion took place at our own shipyards in Zwijndrecht and Dordrecht, we were able to work fast and efficient. Due to that, we have been able to create yet another unique multi-purpose support vessel.’
