Marine Renewables


Within the Marine Renewables sector, we undertake:

  • Environmental survey and monitoring services.  Much of our survey and monitoring is based on 3D-photogrammetry modelling of seabeds and subsurface infrastructure using image sets generated either by divers or our own observation class ROV;
  • Surveys of anchor and mooring systems to include monitoring biofouling and structural integrity; again based on 3D-photogrammetry technology;
  • Non-destructive testing of metal thickness using underwater ultrasound; and 
  • Biofouling and biosecurity monitoring

Our most recent work in the marine renewables sector has been through a research partnership between Tritonia and Sustainable Marine Energy Limited.  As part of their integrated tidal energy systems, Sustainable Marine Energy provide innovative anchoring and mooring systems that are used both for marine renewable energy projects and in aquaculture.  The two companies have been working together to evaluate stereophotogrammetry combined with orthomosaic-based mapping as methods for measuring and monitoring the condition of the direct embedment anchors.  

High-resolution 3D-models combined with point-cloud comparison methods can quickly and accurately quantify areas of deterioration or erosion in the anchors, in addition to measuring the exact depth of penetration.  Level-controlled and digital elevation models have determined the direction and extent of the angle of the anchor’s penetration, and georeferenced orthomosaics were used to provide feedback on the anchor positioning.
