TECHNICAL EXECUTION
Challenge & Delivered Outcome
THE CHALLENGE
Operational & Site Constraints
Harsh sea conditions and erratic boulder fields requiring real-time UXO and obstacle discrimination.
THE OUTCOME
Deliverables & Client Impact
Complete micro-siting corridor chart supplied, saving an estimated 14 days of trenching tool re-routes.
Key Technologies:
Cable route
Boulder clearance
Subsea survey
Plant as-built capture, Mesaieed gas processing facility
Subsea pipeline landfall mapping and shallow gas hazard detection across industrial port waters, verifying pipe burial depths prior to intake dredging.
