    DNV GL and GSI cooperate on AI-based solution to improve welding NDT efficiency

    At Marintec China Trade Fair in Shanghai, DNV GL signed a cooperation agreement with Guangzhou Shipyard International Company Limited (GSI) for a joint development project (jdp) to improve welding non-destructive testing (ndt) efficiency through the automatic detection and assessment of radiography testing (rt) digital images.

    Chen Zhongqian, Chairman of GSI, and Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime, who initiated the project earlier this year, attended the signing ceremony at the DNV GL booth at Marintec China alongside other members of the management teams.

    Zhou Mushun, Chief Engineer of GSI, and Norbert Kray, Regional Manager for Greater China at DNV GL, signed the cooperation agreement on behalf of both parties. Under the agreement, GSI and DNV GL AI Research Center will utilize the latest artificial intelligence (AI) technology to develop a new solution for automatic detection and assessment of welding seam indications in RT digital images.

    Ship building involves countless welds. X­rays are used to detect weld imperfections, e.g. porosity, slag, and cracks. These X­ray images need to be reviewed by non-destructive testing experts, which is very time-consuming. By replacing the manual assessment of welding seam indications with artificial intelligence algorithms, human efforts will only be necessary for the final acceptance review. Thus, unacceptable welds are reported much more quickly, which can lead to shorter building times.

    2019 was a milestone year for the cooperation between GSI and DNV GL, with the 150th DNV GL classed vessels built at GSI. The types of vessels include oil tankers, bulk carriers, semi-submersibles, ro-ro vessels, and polar transport ships. In order to further strengthen the relationship, DNV GL and GSI signed a multi-year strategic cooperation agreement in March.
