Offshore Infrastructure
Use repeatable seabed and asset evidence to support route selection, installation assurance, inspection, integrity management and decommissioning.
Critical Decision Risks
RISK RADAR- Scour, erosion and seabed mobility
- Pipeline and cable exposure or freespan
- Installation and shallow-geohazard risk
Evidence Outcomes
DE-RISKED- High-resolution route and site mapping
- Inspection evidence with clear change detection
- Geohazard and integrity decision support
The decision problem
Pipelines, cables, foundations and other offshore assets interact continuously with the seabed and water column. Conditions observed during design may change during installation and operations, while inspection data can become difficult to compare across campaigns and contractors.
OceanHub treats infrastructure assurance as a lifecycle evidence problem: establish a reliable baseline, detect meaningful change and connect observations to engineering action.
Evidence pathway
1. Route and site definition
Map seabed morphology, shallow geology and geohazards before installation decisions are fixed.
- Route survey: Identify slopes, outcrops, mobile sediments, crossings and potential obstructions.
- Site assessment: Support jack-up, foundation and temporary works planning with appropriate shallow-geological evidence.
- Engineering handoff: Translate survey observations into route, installation and design constraints.
2. Installation and as-built assurance
Capture the installed condition in a form that can serve as the reference for future inspection.
- Position and configuration: Verify location, burial, support and interfaces.
- Exceptions: Record deviations, exposed sections and areas requiring follow-up.
- Data continuity: Preserve comparable spatial and inspection references for later campaigns.
3. Integrity and decommissioning
Use repeat surveys, ROV observations and change detection to identify scour, exposure, freespan, movement or seabed disturbance.
The objective is not simply to collect inspection footage. It is to provide traceable evidence for maintenance prioritisation, intervention planning and final site-clearance decisions.
