When an offshore structure is too large to remove in one piece, it must be cut into sections before it can be lifted from the seabed. That’s exactly what our BOKA Northern Ocean recently did with four subsea structures that needed to be removed as part of a major North Sea decommissioning program.
In an earlier phase of this long-term project, the subsea infrastructure connected to the FPSO in the oil field had already been disconnected. In this stage, the task was to cut the four structures โ towheads weighing between 280 and 600 tons โ into smaller sections, to allow recovery using the BOKA Northern Ocean’s powerful deck crane. A diamond wire saw was deployed to precisely cut the structures into pieces that could be hoisted onto the deck.
Our colleagues from Boskalis Subsea Services have once again demonstrated their ability to deliver a tailor-made decommissioning solution โ an achievement made possible thanks to our unique expertise and our extensive fleet of specialized offshore vessels. We thank the project team for their innovative approach and the crew of the BOKA Northern Ocean for their excellent offshore work.
