In February 2011, Maersk Oil's Gryphon FPSO suffered significant damage in heavy storms in the turbulent North Sea.
After nearly 20 years of uninterrupted service, the FPSO had to leave the Gryphon field for the first time for repairs and upgrade.
Maersk Oil has produced a video, The Recovery Story, which documents how the FPSO and Gryphon field were brought back to life.
