The platform was located on an old depleted oil field in the Dutch Continental Shelf.
Oil production had ceased. The condition of the platform was such that the owner decided to abandon the wells and to remove the platform.
Hydraulic workover was identified as the most efficient way to cut the casings and conductor of each well below the seafloor.
The objective was to cut the 13 5/8” casing, the 20” casing and the 30”conductor at 6 meter below the sea-floor and prepare the casings for removal for 11 wells.
