Pipeline Inspection on Santos GLNG Project Queensland


Client: ASI Group Ltd (for Marine Services Group), Curtis Island, Queensland.

Project: ROV services for ASI Group on the Santos GLNG Project to inspect a 3.4m diameter tunnel (in low visibility), from Curtis Island to mainland.

Using a modified Saab Seaeye Falcon ROV with 5km tether (supplied by ASI Group) Dive Works ROV Pilots and Technicians conducted a long tunnel inspection from Curtis Island to the mainland (near Gladstone).

Multiple sonars were attached to the ROV to gather comprehensive data for the Client report.

“The operation was completed safety and without incident making it the longest ever successful tunnel inspection [by surface powered ROV] in Australia,” says Gregory Jones, Project Manager Pipeline, GLNG Operations Ltd Pty SANTOS.

A pipe was pushed through the tunnel from the mainland to Curtis Island. The tunnel was flooded and ROV deployed to inspect the pipeline going through the tunnel.

  

The 3.4m diameter tunnel is approximately 5.2 km long.
