Qingdao Fanya Marine Service Co., Ltd. is an inspection contractor based in Yantai on the northern coast of Shandong, supporting commercial shipping using the busy bulk and container ports of the Bohai and Yellow Sea region. The firm holds service supplier recognition from ABS, Bureau Veritas, DNV, Korean Register and Lloyd's Register, an approval set that gives access to a wide range of internationally trading tonnage. Day-to-day work focuses on ultrasonic hatch cover tightness testing for bulk carriers and general cargo ships, watertight integrity testing of bulkheads, doors and deck closures, and underwater inspection in lieu of drydocking conducted by trained dive teams. Qingdao Fanya also undertakes a programme of non-destructive testing and remote inspection assignments, applying ultrasonic, magnetic particle and dye penetrant methods to welds, structural details and machinery components during repair and newbuilding work. Reports are prepared in formats acceptable to attending class surveyors and indexed to support shipyard rectification planning during scheduled repair calls. Operating from Yantai gives practical access to repair yards, anchorages and terminals between Qingdao, Penglai and Weihai, and supports rapid mobilisation to nearby ports when survey windows are tight. Procedures follow IACS unified requirements and class society guidance for tightness testing, watertight integrity verification and underwater attendance, with equipment calibration and personnel qualifications maintained in line with approving society standards. Qingdao Fanya coordinates attendances with class surveyors and shipyard planners so that tightness, NDT and underwater work can be completed within a single mobilisation where survey programmes allow. Records of test pressures, acceptance criteria, NDT findings and dive logs are retained for traceability, and reports are released in English where required for international clients running mixed-flag fleets through the Bohai and Yellow Sea trades.
