Van Stee Offshore is proud to announce that its newest addition to the fleet, the DP2 MPSV “Zwerver I”, is nearing completion and will be taken into service mid-June 2020. In the past weeks a variety of tests and trials has been carried out to verify her unique capabilities and functionality. Just after her sea trials for class authority Bureau Veritas, the vessel sailed to the Rotterdam Maasvlakte to conduct the bollard pull tests. The vessel managed to achieve an average bollard pull of 66 T, with maximum values at 69 T.

During DP-trials and commissioning the vessel, equipped with 8 thrusters in total, showed her capability with astonishing results in different configurations.

The vessel is capable to operate in DP2 mode with a draft of only 2,3 m, with 6 thrusters available, which makes her ideal for a variety of operations in tidal areas (high currents) such as cable lay, cable repair, survey operations, ROV support, UXO clearance and many more.

For operations in very shallow waters, 2 spud poles (Ø 1500 mm) are fitted to position the vessel during beaching-, diving- and cable lay operations. There is also a 4/5-point mooring system installed with wire capacities of 1400 m anchor wire.

On board there is a comfortable accommodation for 58 pax including crew, which includes a large messroom, meeting room, client office and gym. VSAT and Sat-TV systems are available in each and every room/cabin. This system including entertainment system is delivered by Bampro.

On the bridge, there is a large survey desk including 19” racks, pre-installed monitor brackets, Clear-Com installation and many more.

The vessel is equipped with 1 large Scaldon AHC knuckleboom crane which lifts 40T @ 20 m in Seastate 3 and 20T @ 27 m in maximum outreach. CT and manriding is included. The crane is equipped with a separate 5T auxiliairy winch and has connections available for additional hydraulic equipment such as a grab, pumps or other hydraulic equipment. The crane is equipped with communication equipment such as VHF, Clear-Com and PA systems. Survey screens are also available for the crane operator. On top of this, there are 2 HS Marine cranes installed, divided on deck to cover the entire 800 m² deck space. On the stern on portside, a 550Tm version, lifting 15T @ 20 m and in the centre of the vessel on portside, a 145Tm type, lifting 3,5T @ 20 m.

In the centre of the vessel, slightly over Port side, a moonpool of 4,2 x 4,2 mtr is integrated in the vessels hull. The moonpool has a removable deck cover, which is flush in deck and a hydraulically operated bottom door. A 2^nd moonpool is located on starboard side close to the accommodation for survey operations.

On the stern, a stern roller of 8000 x 2000 mm is installed including a pair of Kooiman Delta Pins plus Fork.

For towing, anchor handling and eventual 5^th mooring/pull anchor, a large 200T Kraaijeveld winch is fitted. This winch has the capacity of holding 1000 m wire @ Ø 64 mm, and has a holding capacity of 250 T. 2 additional 15T tugger winches are installed for anchor handling and mass flow operations.

Flush mounted container fittings have been added in deck on several locations. The railings/cargo rails are all removable. Deck strength varies between 10 and 20 t/m².

Nothing has been overlooked in order to provide our clients with our well-known quality, flexibility and above all safety.

We are looking forward to receive any questions or charter enquiries!
