DNV GL pioneered the use of drones for ship inspection

During the Greek Maritime Exhibition, DNV GL announced that it has recently successfully applied drones to ship inspections. The test took place in a chemical tanker (ship type shipyard) owned by MSC Apollo owned by Carl Büttner Ship Management GmbH, Germany. Two DNV GL surveyors used the drone to inspect 14 cargo holds for two and a half days.

        “The advantages of using drones are self-evident compared to traditional scaffolding inspection of cargo holds,” said Marine Superintendent and Chief Security Officer, Carl Büttner Maritime Operations Manager and Chief Security Officer of Ship Management, Jochen Huhn. Eliminates the risk of scaffolding paint (purchasing the product library) and saves time. And the image data taken by the drone is very clear and detailed. Of course we are interested in more applications of drones in the future. I am also very interested in the development of this technology in the coming years."

        “The success of the first application of drone surveys reflects the fact that we are investing in the development of innovative ship-level services to support our customers,” he explained. “In the next few years, we will continue to expand our drones. The field of application and the number of offices that can be used for drone surveys. Drone surveys have advantages in terms of time and cost savings and are promising." DNV GL Maritime Department CEO Conut ( Knut ?rbeck-Nilssen) said.

        Checking the cargo hold of the ship is not only time consuming, costly, but also has safety hazards. Routine evaluations of coatings, corrosion, damage, piping, joints, equipment, and safety systems are required. The use of drones for visual inspection of these remote structural components can greatly reduce inspection time and scaffolding costs while improving the safety of surveyors. Today, DNV GL has piloted a drone survey of cargo tanks in a large tanker, a chemical tanker and a bulk carrier (ship-type shipyard) in Europe and China.

        Currently, DNV GL is evaluating the feasibility of using unmanned aerial vehicles or other means to inspect offshore platforms including upper modules, external structures and internal cargo holds.
