Jingjiang Jiangyang Marine Facilities is a Jingjiang-based marine engineering contractor working with shipowners and yards along the lower Yangtze River. The company holds service supplier recognition from ABS, allowing its technicians to perform attendances and testing that flow directly into classification survey files for vessels under that society. Day-to-day activity covers pressure vessel inspection on boilers, air receivers, heat exchangers and other shipboard pressure equipment, including the periodical hydrostatic, pneumatic and non-destructive testing required to keep certificates current. Jingjiang Jiangyang also undertakes underwater inspection in lieu of drydocking, providing video records and written reports that support the deferral of scheduled bottom surveys when hull condition allows. Operating from Jingjiang places the firm within a dense shipbuilding cluster on the Yangtze, with practical access to multiple newbuilding and repair yards, river anchorages and the terminals upstream of the Yangtze estuary used by bulk carriers, tankers and offshore units. Personnel qualifications and equipment calibration are maintained to the requirements of the approving society, and procedures follow IACS unified requirements and ABS rules for pressure equipment and in-water survey. By combining pressure vessel testing with underwater attendances under a single approved provider, the team supports owners and superintendents organising compact survey programmes during short stays at Yangtze ports and inland repair facilities. The team coordinates with attending class surveyors and shipyard planners to align pressure equipment tests, NDT and underwater attendances with available windows during repair stays. Records of test pressures, dwell times, acceptance criteria and dive logs are retained for traceability, and reports are released in English where required for international clients operating in mixed-flag fleets.
