At Marintec China profession fair in Shanghai, DNV GL authorized a participation contract with Guangzhou Shipyard International Company Limited (GSI) for a joint growth job (JDP) to boost welding non-destructive screening (NDT) performance with the automated discovery and also evaluation of radiography screening (RT) electronic photos.

Chen Zhongqian, Chairman of GSI, and also Knut Ørbeck-Nilssen, Chief Executive Officer of DNV GL– Maritime, that started the job previously this year, participated in the finalizing event at the DNV GL cubicle at Marintec China along with various other participants of the monitoring groups.

Zhou Mushun, Chief Engineer of GSI, and also Norbert Kray, Regional Manager for Greater China at DNV GL, authorized the collaboration contract in support of both celebrations.

Under the contract, GSI and also DNV GL AI Research Center will certainly use the current expert system (AI) modern technology to establish a brand-new service for automated discovery and also evaluation of welding joint signs in RT electronic photos.

“This cooperation marks another milestone for GSI’s long and fruitful cooperation with DNV GL over the past 22 years,” stated GSIChairman Chen Zhongqian “As the largest modern integrated shipbuilding enterprise in South China, GSI has rich and detailed welding images. I am glad that with DNV GL’s advanced AI, this data can now be used to contribute to the future development of shipbuilding technology.”

“We are very proud to partner with GSI on this innovative project,” stated DNV GLRegional Manager Norbert Kray “Our ambition is to be a technology leader and explore new solutions for the benefit of our customers. We look forward to helping more Chinese shipbuilders to build high-quality ships with cutting edge solutions such as this.”

Ship structure includes many welds. Xrays are utilized to discover weld flaws, e.g. porosity, slag, and also splits. These Xray photos require to be examined by non-destructive screening specialists, which is extremely taxing. By changing the hands-on evaluation of welding joint signs with expert system formulas, human initiatives will just be needed for the last approval testimonial. Thus, inappropriate welds are reported far more promptly, which can cause much shorter structure times.

“We will build a web-based application to initially provide the new AI solution to ship yards for automated testing of weld seam quality,” stated Dr Pierre C. Sames, Director for DNV GL Group Technology & &Research “Our approach towards weld detection can not only be used in shipbuilding, but in other industries where NDT is used as a quality control tool,” he included.

2019 was a turning point year for the collaboration in between GSI and also DNV GL, with the 150th DNV GL classified vessels constructed at GSI. The kinds of vessels consist of oil vessels, mass providers, semi-submersibles, ro-ro vessels, and also polar transportation ships. In order to additional reinforce the connection, DNV GL and also GSI authorized a multi-year tactical collaboration contract in March.
