Established in 2005 and headquartered in the Qingdao Economic and Technological Development Zone in Shandong Province, Hungkia Marine Engineering Co., Ltd. is a technical services firm dedicated to non-destructive examination, ultrasonic thickness measurement and watertight integrity verification on merchant ships and offshore units. The company supports shipowners, managers and shipyards across northern China, with regular attendance at Qingdao, Yantai, Weihai and Rizhao, and dispatches inspection teams to ports along the wider Bohai Rim and East China Sea coastline. Its core technical scope includes hull ultrasonic thickness gauging for class intermediate, special periodical and Condition Assessment Programme surveys, ultrasonic hatch cover tightness testing in line with IACS UR Z17, and watertight integrity testing of doors, side shell penetrations and bulkhead boundaries. Hungkia also performs in-water surveys with diver support, allowing routine bottom inspections to be carried out at anchorage in lieu of drydocking, and offers conventional NDT methods such as magnetic particle, dye penetrant and ultrasonic flaw detection for welds and structural details. The firm holds approvals from a broad portfolio of classification societies including ABS, Bureau Veritas, CCS, ClassNK, DNV, Indian Register of Shipping, Korean Register, Lloyd's Register and RINA, which allows survey reports to be submitted for statutory and class purposes across most flag administrations. Qualified technicians work under documented procedures, applying calibrated equipment to deliver gauging records, ultrasonic UST printouts and NDT certificates that owners can present directly to attending class surveyors during scheduled surveys.
