    KR completes first drone and crawler hull inspection survey

    The Korean Register (KR) has successfully completed its first hull survey using both a drone and crawler (a type of drone capable of climbing up and down walls) without scaffolds, KR said in its release.

    The remote inspection technology was used for the intermediate survey of the bulk carrier PAN GLOBAL and was completed with the assistance of POSSM Co, Korea’s largest ship management company and HST Technology, who provided the remote inspection technology on 10 November.

    KR’s surveyors have been using remote inspection technology such as drones for surveys since 2017, the equipment allows the surveyor to inspect the vessel without requiring direct access. Since the launch of the service, KR has increased the range of inspection tools used, offering customers a more efficient and safer inspection service, which complements the traditional ship survey system and meets industry requirements.

    Ship surveys usually involve a ‘close-up survey’ and a ‘thickness measurement’ of the hull structures. But to complete the process, surveyors must climb scaffolding (poles and boards made into a temporary framework, used when working on the high parts of a ship) which can be higher than a five-story apartment building. It has been possible to use drones to inspect the highest places, but a scaffold has still been required in order to complete the thickness measurement assessment, making the service inconvenient for shipowners.

    But now using a crawler, it’s possible to measure the thickness of the hull at any point no matter how high, without scaffolding, making drone surveys far more practical and profitable.

    The Korean Register (KR) was established in 1960 with the purpose of promoting safety of life, property and the protection of the marine environment. KR currently classes an international fleet of 3,050 vessels totaling 70 million GT. It is headquartered in Busan, South Korea with a network of 66 offices around the world. KR is authorized to perform statutory and certification services in 81 countries around the world.
