Cyberhawk recently completed a multi-scope inspection of an FPSO in the North Sea. The requirement was to provide a detailed inspection of the flare tip and supporting structure, inert gas vent, internal tank and a survey of the hull of the vessel.
The client had initially planned to use a relatively inexperienced drone operator. However, while developing the risk assessment with said operator, it became clear that the work scope was complex. This meant a more experienced UAV operator was required, with a proven track record and multiple similar projects under its belt. The operator also needed to have the inspection engineering expertise to ensure detailed reports would be produced, which would allow the client to make maintenance decisions. For Cyberhawk, this was a routine inspection that was completed in five days.
Alternative methods for carrying out this scope of work, such as rope access, elevated cradles or scaffolding, would have taken weeks to complete the inspections. The hull of the boat would have been especially tricky, since there was a water outlet with built up growth that was hard to access, and high risk of LSA exposure (Low Specific Activity) which is naturally occurring radioactivity.
Cyberhawk’s solution mitigated the risks associated with other methods, such as working at height or near contaminated areas. It also provided detailed data on the condition of the asset which allowed the client to take maintenance measures wherever needed, thus prioritising actions and significantly minimising costs.
