DNV GL carries out its first offshore drone survey
A look at DNV GL’s drone survey on board Prosafe’s tender support vessel Safe Scandinavia.
DNV GL surveyors have carried out the classification society’s first offshore drone survey on the semisubmersible vessel Safe Scandinavia in the North Sea. This 25,383 GT tender support vessel (TSV) is owned and operated by Prosafe, supporting Statoil’s drilling operations off the coast of Norway. Using camera-equipped drones, DNV GL’s drone pilots checked the TSV’s fairleads and their connection with the vessel’s two columns as part of the intermediate survey.
The classification society has carried out multiple drone surveys on both ships and offshore units, inspecting many areas on board, ranging from tanks and cargo holds to external structures such as jack-up legs. The inspection of such spaces can be both costly and time consuming, and even in some instances potentially dangerous. Using drones to visually check the condition of remote structural components can significantly reduce survey times and staging costs, while at the same time improving surveyor safety.
DNV GL has built a network of trained drone pilots based in Gdynia, Piraeus, Singapore, Houston and Shanghai. This allows drone survey inspections to be offered from any of these hubs. At the same time, DNV GL is developing guidelines and updating our rule set to reflect the use of remote inspection techniques.
