Export cable route survey, Dogger Bank Wind Farm
High-resolution seismic and side-scan sonar reconnaissance for 65km inter-array and export cable burial pathways in variable shallow till and boulder fields.
PROJECT SCOPE & OVERVIEW
About This Campaign
Detailed 3D acoustic inspection of 1,200m quay wall and toe scour, identifying structural spalling and underwater debris prior to new container crane installation.

TECHNICAL EXECUTION
Challenge & Delivered Outcome
THE CHALLENGE
Operational & Site Constraints
Severe acoustic reflection from concrete sheet piles and continuous tugboat wash turbulence.
THE OUTCOME
Deliverables & Client Impact
Clean sub-centimeter point cloud generated with automated scour depth contouring for harbour engineering certification.
Key Technologies:
Quay wall inspection
Bathymetry
Point cloud
Dredge volume survey, Ras Laffan approach channel
A complex dredge pre-survey volume calculation required for deep draft vessel approach, ensuring channel navigation limits complied with strict port authority safety thresholds.
