Technos Mihara (Daishan) Ship Inspection Co., Ltd. is the Chinese ship-inspection subsidiary of Japan's Technos Mihara group, based in Daishan County within the Zhoushan archipelago of Zhejiang Province, an area that hosts some of China's largest ship repair clusters. The Technos Mihara parent organisation in Japan is a long-established specialist in ship inspection and hull condition assessment, and has been involved in joint research with Kawasaki Kisen Kaisha (K Line) on drone-based hull inspection and image-analysis methods using unmanned aerial vehicles. Working from Daishan and the wider Zhoushan repair belt, the company offers ultrasonic hatch cover tightness testing for bulk carriers, general cargo vessels and combination carriers, supporting cargo-readiness surveys and pre-loading inspections at marine terminals and anchorages. Watertight integrity testing of weathertight doors, cargo holds, ramps and penetrations is delivered under the testing requirements of SOLAS II-1 and the IACS Unified Requirements. Test reports are issued in the format expected by ClassNK and other classification societies, with technicians using calibrated ultrasonic transmitter-receiver pairs and inspection logs that capture leak indications, gasket condition and structural defects on a hatch-by-hatch basis. The team's location in Zhoushan provides ready access to ships in repair at the major shipyards on Liuheng, Daishan and Putuo islands, as well as to vessels anchored in Zhoushan Roads. The company is recognised as a service supplier by ClassNK, ensuring acceptance of its tightness-test reports for class surveys on Japanese-classed and other tonnage handled in the region. The Daishan team can also dispatch inspectors to neighbouring shipyards in Ningbo, Shanghai and the surrounding Yangtze River Delta on short notice to meet owners' and surveyors' inspection schedules during busy port-call windows.
