ADUS DeepOcean, a DeepOcean subsidiary, has completed a 3D laser survey offshore Ghana, leading to another three-year contract for DeepOcean Ghana Ltd.
With this stride, as well as the recently completed deepwater subsea 3D laser survey off the West Coast of Africa for Tullow as reported by the media, ADUS DeepOcean and DeepOcean Ghana Ltd are now rated as the forerunners of a new era of high resolution, cost effective data acquisition subsea.
Energy Window International also gathered that with the survey operations covering 12 drill center locations and a total of 27 metrologies in water depths between 800-1800m, the firms were set for new bench marks for high resolution contextual 3D survey, with alternative and rapid “contactless” solution to conventional metrology surveys.
In the dynamic laser survey solution is a deep rated 2G Robotics ULS 500 Pro Laser and Sonardyne’s SPRINT INS system, report said. Adding that the performance of the systems outweighed expectations with accuracies approaching 1cm in dynamic operation.
More advantageous is the accurate 3D “point clouds”, which results from the survey, and added is the innovative modelling techniques developed in house, which provides DeepoOcean engineers with valuable quantitative and contextual information to better inform IMR tasks, and undertake metrology, thereby increasing efficiency for the client.
“The detail achieved by ADUS DeepOcean’s recent dynamic subsea laser surveys has far exceeded expectation. The data and images gathered have proved very valuable in increasing our understanding of the dynamics of the subsea assets, enabling more informed decision making,” Hugues Villedey, subsea projects manager at Tullow Ghana was reported to have said.
