The M.V. Poseidon was recently contracted by PanGeo Subsea (Scotland) Ltd. to support the deployment and operation of their specialist “Acoustic Corer” equipment in Liverpool Bay on behalf of a major wind farm installation company. This specialist equipment was deployed utilising the Poseidon’s 15m, 20 Tonne capacity “A” Frame with sub-sea positioning and ROV services provided by Neptune ehf.
The Acoustic Corer ™ 3D technology uses multi-aspect acoustic intensity imaging to delineate sub seabed stratigraphy and buried geohazards such as boulders, hard layers, shallow gas, and abandoned seabed infrastructure. These present a considerable potential risk and cost if encountered during the installation of offshore infrastructure.
The Acoustic Corer sonar heads incorporate both dual-frequency chirp and parametric sonar, and deliver high resolution, multi aspect 12m diameter volumetric images of the sub seabed in real time. These volumetric images provide 3D data on geohazards with penetration into the sub seabed to depths of 40m depending on complexity.
