The 75.5-metre self-elevating jack-up Seafox 7 has undergone its second five-year survey and maintenance works at Damen Shiprepair Amsterdam (DSAm).
The works began with high-pressure washing of the bottom, sides and spudcans, after which one of the spudcans was removed for inspection, Damen said.
Two deep well water risers were also removed and transported using SPMTs to the DSAm paint shop for blasting and repainting. Specialists arranged by the owner identified the need for some repairs on one of the risers and so it was moved to the yard for repairs before its blasting and repainting. The risers were then reinstalled using the vessel’s own crane.
In addition to the projects arising from the scheduled inspection, other works took place including works on two fresh water tanks. For the first tank, an additional manhole was fitted while the vessel was in dry dock. The second tank was also fitted with a second manhole while the original one was modified, this time while Seafox 7 was in the layby berth. Following the repairs, they underwent grinding and repainting.
Following ten days in the dry dock, Seafox 7 was refloated and moved out from the dry dock number four to berth number one for the main crane works.
To perform and test the repairs on the vessel’s 270-tonne crane, ten containers were stacked one on top of the other to form the support for the main crane boom. With the boom lowered and secured the repair works could get underway. Once the boom was repaired it was repainted.
Back in February 2018, Damen Verolme Rotterdam (DVR) shipyard carried out refit works on Seafox 5 after which the jack-up was ready to start installing wind turbines on the Merkur offshore wind farms in the German North Sea.
