SeaVision, Three-Dimensional Underwater Laser Imaging System
In recent years, three-dimensional (3D) imaging sensors have increased in popularity as a tool for surface-based structural integrity assessment. These sensors provide 3D volumetric information that can be compared against baseline models for the detection of structural defects. Kraken’s SeaVision is a subsea high resolution full colour laser imaging sensor that transfers these capabilities to the subsea domain. With the deployment of offshore wind set to almost triple in the next 10 years, the need for innovative and low-risk solutions to inspect assets is crucial. Traditional inspection regimes need to be enriched with full 3D digitalisation of the inspected subsea structure. Cloud enabled four-dimensional (4D) data analytics, which track the development of the asset over time, are a step forward towards more cost-effective subsea asset management.

SeaVision is an underwater laser scanning system produced by Kraken Robotik GmbH. As one of the winners of the latest Carbon Trust Subsea Inspection innovation competition, the system will be trialled in summer 2018 as part of a novel method to inspect offshore wind substructures.
