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 scaffolding
KR used the remote inspection technology for the intermediate survey of bulk carrier Pan Global which 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 2020.
POSSM head of the maritime technology department Park Hyeon-chan said, "We are very pleased to apply KR’s advanced ship inspection technology for the first time to our POSSM ships. We look forward to benefiting further from KR’s digital tools and processes which I believe will improve our price competitiveness and operational efficiency.”
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.
KR Survey Division executive vice president Yoon Boo-geun said "Remote inspection technology such as drones and crawlers offer ship surveyors an exceptional decision-making tool, ensuring the survey quality is equal to or higher than that of a direct inspection. KR continues to apply new technologies to its services to increase the efficiency and simplicity of the survey work process and to improve the safety of the working environment for shipping company representatives and our surveyors.”
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 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 to complete the thickness measurement assessment, making the service inconvenient for shipowners. But now by using a crawler, it is 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.
This technology is applicable to crude oil, oil product and chemical tankers, too. Sign up to hear expert opinion at the Tanker Shipping & Trade conference 16-18 November 2020.
