Survey you can stop thinking about.
Downtime is usually decided long before the vessel sails. We make that decision carefully.
What we survey.
Bathymetric survey
Multibeam and single-beam depth and backscatter: the shape of the seabed, for design, routing, dredging and navigation safety.
Hydrographic survey
Ports, channels, terminals, rivers and inland waters, with tide and water-level control and a stated datum, to the accuracy order your project sets.
Geophysical survey
Side-scan sonar, sub-bottom profiler, magnetometer and UHR seismic: hazards, buried objects and shallow geology, interpreted and not just plotted.
Geotechnical survey
CPT, borehole and sampling coordination, with logs and results delivered in a form designers can use.
Positioning and navigation
GNSS, USBL and inertial positioning with calibration and quality checks, for vessels, ROVs and subsea structures.
Pipeline and cable survey
Route, pre-lay, as-laid, free-span, burial and post-lay surveys for pipelines, flowlines and cables.
Site and hazard survey
Obstruction, wreck, debris and boulder searches before drilling, piling, dredging or installation.
ROV and visual survey
ROV-based inspection and survey of subsea assets, with findings reported while the vessel is still on site.
Construction and as-built survey
Positioning during installation, as-built and clearance verification, and dredge volumes before and after.
Topographic and coastal survey
Shoreline, landfall and beach-to-offshore topography, with GNSS and total-station control on land.
Monitoring and repeat survey
Scour, siltation, seabed change and asset movement, measured the same way each time so the differences mean something.
How a survey job runs.
- Scope and planning: we confirm the accuracy order, datum, deliverables, permits and the host authorities before anything is priced.
- Mobilisation: equipment is calibrated and checked, and personnel credentials are verified before they sail.
- Acquisition: quality control runs on board, with daily progress reports to you.
- Processing and interpretation: done in-house, with an independent check by a second person.
- Reporting: a survey report that states the method, the accuracy and the checks behind every figure.
- Close-out: data handover in the formats your engineers use, and answers to their questions.
Competence is calm.
Behind every figure is someone who checked it twice. Calm decks. Quiet inboxes. Nothing to explain to the board.
You receive.
- Gridded surfaces, charts and cross-sections
- Contact, anomaly and hazard registers
- Route position lists and as-laid or as-built records
- Geotechnical logs and summaries
- GIS- and CAD-ready data
- A survey report with stated accuracy and checks
We work to the accuracy order your specification sets, aligned to IHO S-44 for hydrographic survey and IMCA guidance for offshore operations, and we state the datum, the method and the uncertainty beside every figure. Our standards.
Where it is used.
- Ports, harbours and dredging
- Subsea cables and landings
- Offshore wind and renewables
- Pipelines, platforms and subsea infrastructure for oil and gas operators
Around survey.
Data, charting and reporting
Processing, interpretation, charts and independent QC of third-party data.
Subsea and ROV support
Installation, protection, inspection and integrity support.
Project management and representation
Your representative between the owner and the contractors.
Technical and asset advisory
Specification, method and integrity advice.
Equipment Exchange
Survey equipment, vessels and vetted specialists, arranged under one agreement.
The Second Look.
Send us one dataset or one deliverable. We review it and tell you plainly what we see. The scope is agreed before we start. We only take on a review we can stand behind.
