Surveys for subsea pipelines and cables
Power Potential One carries out engineering surveys and investigations for the routing and laying of subsea pipelines and cables, as well as studies of the continental shelf.
We gather the data that designers, contractors and operators need to select a safe route, assess seabed conditions and plan installation — from the first desktop study to the as-laid survey — and we support the laying of subsea cables along the approved route.
From seabed data to an approved route

Side-scan sonar imaging of boulders, debris, wrecks and seabed texture
SSS - Shallow geology
Sub-bottom profiling of the sediment layers beneath the seabed
SBP - Existing assets
Magnetometer detection of pipelines, cables and other buried objects
MAG - Geotechnics
Cone penetration tests, vibrocores and seabed sampling with laboratory testing
CPT · VC - Environment
Baseline sampling of seawater, sediments and seabed habitats
ENV - Installation support
Pre-lay, as-laid and as-built surveys during construction

Subsea cable laying
We lay subsea power and communication cables and take the work from route engineering to the final burial survey.
- 01
Cable route engineering
Route selection on the survey data: seabed conditions, slopes, obstructions and existing assets along the corridor.
- 02
Lay and burial
Cable laying along the approved route with burial into the seabed where the soil and the project require protection.
- 03
Crossings and protection
Crossings of existing pipelines and cables, and protection of the cable where it cannot be buried.
- 04
As-laid and burial surveys
Survey of the cable position and burial depth after installation, delivered as as-laid records.
Continental shelf investigation
On the continental shelf we map the seabed and its shallow geology over wider areas: water depth and relief, sediment types, rock outcrops and geohazards such as steep slopes, mobile sediments and shallow gas. The results support pipeline and cable routes, offshore platforms, terminals and other marine infrastructure.
