Dutch ship design company Conoship International has signed a contract with the Chinese Mawei Shipyard for the design of the two new multipurpose DP2 B-type vessels for Spliethoff. The vessels are built under class of Lloyd’s Register, have ice class 1A and also comply with the Polar code.

Shipping company Spliethoff Group, Amsterdam, has recently ordered ten new ships from Chinese shipyards. For nine of these, Conoship International has been selected to deliver the design. In addition to the four Lift-on/Lift-off (LoLo) vessels for Wijnne Barends and three Roll-on/Lift-off (RoLo) vessels for Bore Ltd., the latest order consist of two new B-types. For these two, Conoship has been commissioned to deliver the ship’s complete class approval package: basic design/structure and systems.

Ideal for Offshore Supply

The ships will be equipped with a 5300-kW diesel engine, four 2000-kW auxiliary engines, a scrubber and selective catalytic reduction (SCR) system to comply with the requirements of IMO Tier III. This state-of-the-art ship combines the intake of a multi-purpose vessel with DP2, station-keeping ability of up to Bft 6, making it ideal for supplying large volumes and heavy cargo directly offshore.

With 12,500 metric tonnes deadweight, an open top notation, more than 2875 square metres of cargo deck space, two tween deck levels and 5700 square metres of total deck space, the intake of the B-Type is significantly higher than existing offshore supply vessels.

Pipe-handling Gantry Crane and Heavy Lift Mast Cranes

To obtain the fast, safe and efficient loading and discharge of pipes, both on and offshore, the vessel has a removable, automated, pipe-handling gantry crane installed. The B-Type is also equipped with two Huisman 500 mt Heavy Lift Mast cranes, making it suitable for both heavy lift transportation and offshore installation.

The ships to be named Brouwersgracht and Bloemgracht are to be delivered in October 2021 en February 2022.
