Offshore staff
LONDON – Petrofac and James Fisher Asset Information Services have collaborated on a development designed to eliminate the need for offshore surveys ahead of modification scopes.
The digital process allows offshore crews to capture detailed visual and measurement data through the ‘Self-Capture Point Cloud’.
Photogrammetric data is compiled using intuitive camera equipment, transferred to the offshore asset’s digital twin and converted into a point cloud.
This can then be used to design asset modifications to a high level of dimensional accuracy, Petrofac claims. The company employed the technique for a spool piece replacement in the North Sea, avoiding the need to mobilize a survey team.
Steve Johnson, vice president of Digital for Petrofac’s Engineering and Production Services business, said: “This type of digital execution provides a means to optimize use of existing infrastructure by extending field life, whilst reducing offshore travel…
“With all our customers’ assets requiring planned production shutdowns incorporating pipework anomalies and new subsea tiebacks requiring piping tie-ins, this technology will accelerate what is often a critical path activity and allow production to be started earlier than ever before.”
