Plant Inspection & Testing (Shenzhen) Co., Ltd. is a Shenzhen-based inspection company supporting merchant shipping and shoreside industrial clients in the Pearl River Delta with non-destructive examination, hull structural measurement and tightness verification work. Operating from Guangdong Province, the firm dispatches qualified surveyors and NDT technicians to vessels calling at Yantian, Shekou, Chiwan, Mawan, Nansha and Hong Kong, supporting both planned class survey work and unscheduled investigations following incidents or charter requirements. Core technical services concentrate on ultrasonic hatch cover tightness testing carried out in accordance with IACS UR Z17 for bulk carriers and multipurpose ships, hull ultrasonic thickness gauging in support of class intermediate surveys, special periodical surveys and Condition Assessment Programmes, watertight integrity testing of doors, manhole covers and bulkhead penetrations, and broader non-destructive examination using ultrasonic flaw detection, magnetic particle inspection and dye penetrant testing on welded structure. The team works under documented procedures using calibrated ultrasonic gauges and flaw detectors, providing thickness reports, tightness test records and NDT certificates that can be submitted directly to attending class surveyors. The company is class-approved by ABS, Bureau Veritas and CCS, allowing reports to be used for statutory and class purposes on a wide range of Chinese and internationally flagged tonnage. Attendance can be arranged during cargo operations to minimise off-hire, with surveyor mobilisation coordinated from the Shenzhen base.
