Terra Drone conducts North Sea survey on behalf of Shell


Terra Drone Europe has conducted an aerial 3D survey of an offshore platform in the North Sea on behalf of Shell.

It consisted of two parts, one to create a 3D point cloud and the second to accurately check the position of the platform using GNSS readings.

The aim of the 3D survey was to see if any conflict would arise if a drilling rig were to be positioned over the platform complex.

Those involved described that it was necessary as the as-build drawings do not always represent the current situation and if a conflict arises then it is a costly affair to have the drilling rig waiting for this to be resolved.

The platform complex was positioned many years ago when GNSS survey techniques were not yet common.

Several coordinates were known but a check needed to be carried out to position all the elements of the platform.

Consequently, two GNSS receivers were installed at several locations on each platform and logged raw data that was later post processed.
