Frequently asked questions

What is touchdown monitoring?

Real-time monitoring of the point where the pipeline meets the seabed during pipelay, to control its position and document the as-laid condition as installation progresses.

What deliverables does an as-built survey produce?

The verified final position of installed pipelines and structures, with coordinates and kilometer points (KP), reports and drawings ready for project engineering close-out.

How do you integrate the ROV into construction work?

With the Leopard we verify the installation of manifolds, valves and umbilicals, perform structural inspection during the works and provide continuous subsea positioning to the operation.
