SCOUR FEATURE 3D VISUALISATION TECHNOLOGY
Unlike oil & gas, the renewables sector is still at a stage where large parts of the supply chain, and well- defined procedures and practices, are not fully developed.
This fact represents an opportunity for new technologies and innovative approaches – such as the 3D visualisation technology outlined here – to find their place and become part of the standard procedure for effective operation & maintenance procedures in the future
SCOUR
Aside from the danger of unsupported cables, scour affects foundation stability. This technology effectively maps scour and presents it in a fully metrical 3D visualisation for a greater understanding of the problem.
More importantly though this allows detailed monitoring over time, by comparing successive datasets, and provides the ability to accurately measure the depth and overall dimensions of scour as well as the volume of material removed.
of Mexico, and more recently, the stricken cruise ship Costa Concordia in Italy and the cargo ship Rena which sunk off the coast of New Zealand.
Building on its success, ADUS has recently begun to successfully deploy its know-how and technologies in the offshore wind and oil & gas markets, where it can be used to provide high quality 3D images of subsea structures such as offshore facilities, wind turbine foundations and seabed architecture.

IMPORTANT FACTORS
ADUS DeepOcean has engaged with a number of UK windfarm operators in order to understand their ongoing inspection requirements. There is an essential need to identify and monitor a number of important factors which include…
• Scour around the base of monopiles • Cable exposure on the seafloor • Movement of sand waves across the site
• Cable freespan • Cable tension • Cable bend radius
MONITORING
This 3D visualisation technology is directly applicable for the effective monitoring of these factors and can add value by increasing opportunity, speed & quality of data acquisition, and reducing use of divers and ROVs, whose tasks can involve the manual measurement of these factors. The use of divers in such operations is often problematic with down time caused by weather, but also the requirement only to dive during slack water periods.
ABOUT ADUS DEEPOCEAN ADUS DeepOcean Ltd was formed in 2013 following the acquisition of a 50% interest in ADUS by DeepOcean group. Formerly Advanced Underwater Surveys Ltd, ADUS was originally a spin out from the University of St Andrews and Dundee University and has rapidly acquired a global reputation in the marine salvage market for its stunning subsea 3D visualisations.
The company is known for such high profile work as the survey of the wreck of the oil rig Deepwater Horizon in the Gulf
