Maersk will use an I-class vessel for removal of the four 30-in. jacket-mounted drilling conductors and two associated conductor guide frames.
I-class vessels, the company said, feature dual cranes and work ROVs deployed via a moonpool, and are designed for maximized uptime and weather operability.
“This is a technically challenging scope with large periods of time spent alongside a platform,” said Olivier Trouvé, head of Integrated Solutions. “The removal of older conductors that cannot be pulled through topsides remains a challenge throughout the North Sea.”
Project management and engineering starts this year, with offshore execution to follow in 2022 or 2023.
