PanGeo Subsea completes decommissioning survey for Perenco (UK) Limited
PanGeo Subsea are pleased to announce the successful completion of a decommissioning survey for Perenco (UK) Limited on their Welland gasfield. The workscope included carrying out both SBI and multi-beam surveys on the Welland platform and three remote wellheads to locate, size and verify the depth of burial of concrete mattresses laid decades ago to protect pipeline and umbilicals. PanGeo verified depth of burial of the concrete mattresses to a resolution of 5cm.
This project was the first time we have interfaced our SBI to Atlantic Maritime’s ROGE ROV system onboard the Atlantic Explorer.
