BNR 206 - Zwerver II

Shipyard Gebr. Kooiman BV delivers a new multi-purpose DP-2 support vessel to customer HvS Dredging Support BV in Harlingen. Thanks to close cooperation between HvSDS and Kooiman Marine Group, a number of major, innovative solutions were devised and implemented, giving this vessel, the new ‘Zwerver II’, the capacity to serve the top end of the market segment.

The vessel is equipped with DP II, 4-point mooring, a 510 Tm crane with Active Heave Compensated winch, a conventional crane of 370 Tm and a Passive Heave Compensated gangway for putting personnel on wind turbines and platforms. The pulling power of the vessel is around 65 T, which is exceptional in this class with its draught of only 2.7 metres.

The vessel was designed and built under Bureau Veritas and will sail under the Dutch flag. The vessel is highly versatile and can be put to many uses, especially in the offshore and the renewables markets with services such as dredging support, anchor handling, cable laying, cable excavation, diving support, ROV support and many other activities.

The accommodation has MLC certification and can house 14 persons. This number can be increased to 18 persons by using the accommodation containers present, so that apart from the crew of the ship, 12 specialized personnel members can work and stay on the vessel.

Kooiman previously developed and delivered Zwerver I (2007) and Zwerver III (2011) jointly with HvSDS. Zwerver II was delivered in the spring of 2016.
