Aerial inspection speeds North Sea Gryphon tank check

Offshore staff

LIVINGSTON, UK – Cyberhawk Innovations has completed its first ever inspection of a cargo oil tank on an operational FPSO, using a remotely operated aerial vehicle (ROAV).

The program took place on board the Maersk Oil-operated Gryphon FPSO in the UK central North Sea.

Maersk has to visually inspect cargo tanks for integrity, damage assessment, and class certification. Normally rope access technicians perform this duty, suspended on ropes to inspect the tank structure, examining areas subject to stress such as stiffeners, brackets, bracing, webs, and stringers.

However, there are risks working at height for sustained periods and in confined spaces.

Cyberhawk mobilized a two-man ROAV team, one piloting the vehicle, the other an inspection engineer. They inspected critical components of the tank within a day, compared to three-four days for the same scope using rope access, the company added.
