The ‘OOS Walcheren’ is the 3rd vessel using the asymmetric brace-less semi-submersible design within the OOS family.
The first is the ‘OOS Gretha’, currently operating in Brazil, and the 2nd is the ‘OOS Serooskerke’, which is under construction and due for delivery in Q3 2019.
A total of 28 sub blocks are being keel layed. The weight of each block range between 40mt to 210mt. The dry dock, where she is being keel layed, spans at 530m in length and 130m in breadth, which is one of the largest dry docks in China.
The ‘OOS Walcheren’ has a total of 212 sub blocks which will be fully erected in the dry dock. After the erection is complete, the ‘OOS Walcheren’ will boast an overall size of 138m in length and 81m in breadth. She will be staying in the dry dock for 8 months, where she will be carefully outfitted and assembled before undocking at the end of July 2019.
The keel lay is a significant milestone because it marks the beginning of forming the vessel. The progress of the construction will speed up rapidly after the keel laying, because of the exceptional crane facilities available at the dry dock. There are five 60mt lattice boom cranes and one 900mt gantry crane serving the dry dock.
