Based in Dalian, in China's Liaoning province, DALIAN QIANJING METAL TECHNOLOGY CO., LTD. delivers non-destructive testing and tightness verification services that support classification surveys and routine maintenance of merchant vessels calling at northern Chinese ports. The technical team focuses on ultrasonic hatch cover testing, watertight integrity examinations and a broader range of NDT and remote inspection tasks used to confirm the structural and operational soundness of cargo holds, weather decks and machinery spaces. Ultrasonic hatch cover work is carried out in accordance with industry guidance, providing owners and managers with documented evidence that hatch covers and access openings can withstand seawater ingress in normal trading conditions. Watertight integrity testing covers bulkheads, hatches, doors and similar boundaries, complementing the ultrasonic programmes with quantitative verification of seal performance. The NDT activity supports condition monitoring during periodical, intermediate and special surveys, helping identify cracks, corrosion thinning and weld defects before they progress into structural concerns. Working principally with bulk carriers, general cargo vessels and coastal tonnage trading through Dalian and adjacent ports, The technical team organises mobile crews and equipment so attendance can be coordinated with port stays, dry-docking windows and lay-up periods. Service approvals from ABS and CCS confirm that the workshop, procedures and personnel meet the requirements set by these classification societies for the disciplines on offer. Direct contact with Chinese-speaking and English-speaking coordinators, combined with the firm's proximity to Dalian's repair yards and anchorages, makes the company a practical partner for inspection and testing scopes triggered by class survey cycles or charter-party inspection clauses. The Dalian Qianjing technical office supports coordination with foreign owners, charterers and crewing departments arranging attendance during routine port calls, voyage repairs or focused class survey campaigns at northern Chinese terminals and anchorages serving bulk, general cargo and coastal trades.
