Bonad (Tianjin) Port Engineering Co., Ltd.

Bonad (Tianjin) Port Engineering is a Tianjin-based marine engineering firm delivering hull condition assessment and integrity testing for ocean-going vessels calling at northern China ports. The company maintains class-society approvals from DNV, Lloyd's Register and ABS, allowing its surveyors to perform statutory and intermediate work that feeds directly into classification records. Day-to-day activity centres on hull ultrasonic thickness gauging used to confirm plate diminution against original scantlings, ultrasonic hatch cover tightness testing of weather decks on bulk carriers and general cargo ships, and watertight integrity testing of bulkheads, doors and deck closures. The team also conducts a broader range of non-destructive testing and remote inspection assignments, supporting periodical and damage surveys without taking equipment out of service. Underwater inspection in lieu of drydocking is offered to operators seeking to defer scheduled hull surveys while remaining in compliance, with technicians providing video records and reports formatted for class acceptance. Working from the Port of Tianjin and the wider Bohai Bay anchorages, BONAD is positioned to attend vessels during cargo operations, at lay-up berths or in shipyards, coordinating multiple test disciplines into a single attendance to minimise off-hire time. Procedures are written under the relevant IACS unified requirements and class society guidance notes, with calibration of ultrasonic equipment and qualification of personnel maintained to support the validity of issued reports. By combining gauging, tightness testing and underwater services within one approved provider, the firm supports owners, managers and superintendents preparing tonnage for special, intermediate and renewal surveys across the Tianjin region. Quality records are retained for traceability, and reports are released in English where required for international clients managing enhanced survey items across mixed-flag fleets at Bohai Bay terminals.
