Founded in 2009 and headquartered in Shenzhen, Guangdong Province, HKT Marine Technology Co., Ltd. is an independent inspection and testing house focused on the merchant shipping market in the Pearl River Delta and across southern Chinese ports. The company maintains an ISO 9001 quality management system and is recognized by major IACS classification societies including ABS, Bureau Veritas, CCS, ClassNK, DNV, Indian Register of Shipping, Korean Register, Lloyd's Register and the Polish Register of Shipping, allowing its reports to be used for statutory and class surveys on merchant tonnage. Core technical capabilities centre on ultrasonic thickness measurement of hull plating, deck plating, internal structures and tank boundaries, supporting intermediate surveys, special periodical surveys and Condition Assessment Programmes for ageing vessels. HKT also performs ultrasonic hatch cover tightness testing in accordance with IACS UR Z17, watertight integrity testing of doors and bulkhead penetrations, and non-destructive examination using magnetic particle and dye penetrant methods on welds and critical components. For tankers, where staging and rafting are impractical, the company deploys IRATA rope access technicians to reach high-level internal structures, reducing off-hire time during cargo operations. Additional service lines cover in-water hull surveys with diver support, NDT and remote inspection for condition monitoring, and onboard troubleshooting of pneumatic, electric, electronic and hydraulic ship systems. With its base in Shenzhen, HKT supports vessels calling at Yantian, Shekou, Guangzhou, Zhuhai and Hong Kong, dispatching qualified surveyors and NDT Level II technicians to anchorages, terminals and repair yards across the region.
