Jiangsu Cootech Technology Service is a Suzhou-based testing house focused on laboratory testing and non-destructive testing for the shipbuilding, ship repair and offshore supply chain in eastern China. The team supports new-build yards, equipment manufacturers and operators by carrying out NDT and remote inspection on welds, plating, castings, forgings and assemblies that fall under classification scope or owner specification, using techniques selected to match the materials, geometries and acceptance criteria involved. Laboratory testing complements the on-site NDT activity with controlled examination of samples and components, supporting documentation packages and audit trails required by class, flag and owner stakeholders. The firm is positioned to attend yards and workshops across the Yangtze River Delta, including facilities around Suzhou, Wuxi, Nantong, Zhangjiagang and Shanghai, where shipbuilding and marine equipment manufacturing are concentrated. A service approval from ABS evidences that procedures, equipment and qualified personnel meet the criteria the classification society sets for NDT contractors operating in support of newbuilding and service work. The technical office prepares reports in formats acceptable to attending surveyors and to QA departments at shipyards and equipment vendors, helping projects move through inspection milestones without rework. With Chinese and English-language working capability, the Cootech team coordinates project planning, technician scheduling and final documentation for clients ranging from large construction projects to individual component examinations during fabrication and overhaul phases of merchant vessel programmes. Working with shipyards, equipment vendors and ship management offices across the Yangtze River Delta, Jiangsu Cootech supports projects ranging from large construction programmes and routine periodical surveys to focused damage and quality investigations, providing technical reports and supporting documentation that integrate cleanly into class files, yard QA systems and owner planned maintenance records for international merchant operators and Chinese newbuilding programmes alike.
