Asset Inspection

Bibby HydroMap provides high-resolution 3D underwater asset inspection services

Asset Inspection

Combining a range of marine and terrestrial survey techniques utilising a range of high-specification positioning, marine survey, scanning and photogrammetry equipment, we are able to provide high-resolution imagery of underwater structures, providing a cost-effective substitute for traditional techniques.

Our inshore vessels, such as Pulsar, can be equipped with mutlibeam echosounders to measure seabed bathymetry, high-frequency scanning sonar to provide high resolution 3D point cloud data below the waterline, 360 degree camera for detailed photogrammetry and a laser scanner for inspection above the water line. These techniques can also be supplemented with UAV based LiDAR, photogrammetry and HD camera in addition to land-based laser scanning.

Sensors can also be deployed from tripods or shore-side cranes where required. 

Data is processed, analysed and compiled by specialist surveyors in our head office in Bromborough, with deliverables and timescales tailored to suit individual project needs. Our 3D modelling of these assets provides essential dta to help mitigate risk both now and in the future. 

Key Benefits

  • Provides highly detailed data, removing the need for traditional visual inspection
  • Cost effective
  • Removes any subjectivity in interpretation
  • Allows accurate monitoring of any integrity changes over time
  • Improved site safety in comparison to diving services

Our core Asset Inspection services include:

  • Routine monitoring of dock walls, sluices, caissons, lock gates, bridge abutments and other areas of interest
  • Scour and dredge monitoring
  • Emergency surveys following storm events or damage
  • Bridge clearance surveys
  • Post-construction confirmation surveys
  • Debris surveys
  • Flood risk mapping and volume calculations
  • Structural inspections


Within the port and harbour industry, our work is focused mainly around routine monitoring, damage inspection, and as-built surveying. Our offering is flexible and responsive, and we are comfortable working with various deployment techniques to reduce cost, for example utilising dock-side cranes to deploy the required systems.

Inland Waterways

We perform surveys of canals and other inland waterways to provide current information on debris and other hazards in the water column, structural integrity, scour around structures, and volume calculations for dredging, flood risk mapping, as well as positioning of marine structures such as bridges.


Combining both marine and land-based survey techniques, we can offer a complete monitoring and inspection solution both above and below the waterline. Our vessels and equipment are ideally suited to working in shallow water environments, and our flexible and responsive service can react to provide current information following emergency events.

Offshore Renewables

Having provided various survey services to the offshore renewables industry for almost two decades, we are well placed to provide offshore integrity monitoring services using our 24hr vessels Bibby Tethra and Bibby Athena. Combining a range of vessel-mounted, subsea and remote technologies, we are able to provide monitoring and inspection services on turbines, offshore substations, array and export cables.

Bibby HydroMap carried out a combined underwater 3D sonar survey and above water laser scan survey for WSP during the condition survey of a large oil jetty.  Bibby HydroMap was able to mobilise its equipment at short notice, successfully carrying out the survey within a short time frame, and safely executing the survey around terminal operations and challenging tidal conditions.  Good communication was maintained during the complex post-survey data processing.  An interim review of the survey data with Bibby HydroMap's surveyors during processing was particularly useful for understanding how best to utilise the data collected.  Following delivery of the survey data, Bibby HydroMap provided valuable additional advice to support the construction of a point-cloud model.
