Case Study

Saving 80% + on offshore structural inspections

            

Challenge:

Sky-Futures were tasked with completing a UAV (Unmanned Aerial Vehicle) Inspection for a major oil and gas client’s large, shallow water oil platform in the UK North Sea such that they could make an informed decision with respect to the assets condition.

The project was large with 14 separate inspection scopes including; under deck, turbine exhausts, flare tower, flare tower bridge support, flare stack and an external perimeter sweep and other hard to access structural areas.

Solution:

Because of the scale of the task, the UAV operating team planned in detail how they would gather all the inspection data in a safe and efficient manner. This included highlighting flight plans, no fly zones and detailed inspection requirements to ensure that the inspection data was gathered in a safe and efficient manner.

As well as flying the UAV from the platform, the Sky-Futures team also flew from a support vessel in order to get the highest quality data. Despite the size of the scope, the UAV inspection was completed in 12 days, and because of this, an additional scope of work on an outlying platform was also completed during the time-frame. All areas were captured using a combination of High Definition video, stills and thermal imagery.

Result:

The client praised Sky-Futures for their flexibility, especially due to the fact that the UAV team were working on an extremely busy and complex platform, but carried out the inspection with the minimum of interference. All the while, it was ensured that our safety procedures were of an excellent standard and not compromised.

The client commented that image and video data was of significant value in providing a good understanding of the condition of the platform whilst the reports provided a good baseline understanding of the platform condition. The outcome of the inspection was that it negated the requirement for a rope access inspection that had previously been planned.

This job resulted in a saving of:

700 days of rope access inspection work.
40 days of support vessel hire for supporting rope access inspection work.
28 days of work that would have been required during a shutdown.
