Guangzhou Haihui Shipping Technology Co., Ltd. is a marine inspection company based in Guangzhou, focused on hull ultrasonic thickness gauging for commercial shipping using the Pearl River Delta. The firm holds service supplier recognition from ABS, China Classification Society, IRClass and Lloyd's Register, supporting attendances on vessels operating under several major flag and class regimes. Day-to-day work involves gauging shell plating, deck plating, internal structures, tank boundaries and critical longitudinal members on tankers, bulk carriers and general cargo ships to confirm remaining thickness against original construction values. Surveys are commonly carried out in support of intermediate and renewal class surveys, condition assessment programmes and pre-purchase inspections, with reports prepared in formats acceptable to the attending classification surveyor. Operating from Guangzhou allows the technicians of Guangzhou Haihui to mobilise quickly to anchorages, terminals and shipyards across the Pearl River Delta, including Nansha, Huangpu, Shekou and surrounding repair facilities. Equipment is maintained through documented calibration procedures, and operators hold the qualifications expected by the approving societies for ultrasonic thickness measurement on marine structures. Procedures are written in line with IACS unified requirements covering close-up survey and thickness gauging of bulk carriers, oil tankers and other vessel types subject to enhanced survey programmes. By concentrating on a focused gauging discipline, the team aims to deliver consistent, traceable measurements that allow owners and managers to plan steel renewal works during dockings with confidence. Records of measurements and acceptance criteria are retained for traceability, and reports are released in English where required for international clients. Operating in the Pearl River Delta also gives the team practical reach to vessels calling at Hong Kong anchorages, supporting owners and technical managers who need fast mobilisation between South China terminals and adjacent waters during tight survey and repair windows.
