Marine Renewables

 

Environmental survey and monitoring services

Much of our survey and monitoring is based on 3D photogrammetry modelling of seabeds and subsurface infrastructure using images generated either by divers or our own observation class ROV

Non-destructive testing of metal thickness

We conduct ultrasonic thickness gauging using the Cygnus Dive Underwater Gauge, which can provide measurements of metals up to 250mm thick.

Surveys of anchor and mooring systems

Our surveys include the assessment of biofouling and structural integrity, based on 3D photogrammetry technology

Biofouling and biosecurity monitoring

Our team of marine scientists are trained in the identification and removal of invasive marine species such as Didemnum vexillum, and can provide quantitative photo and video surveys of biofouling.

Our most recent work in the marine renewables sector has been through a research partnership between Tritonia Scientific 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 3D photogrammetry 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.
