The pressure vessel inspection scope covers in-service and manufacturing examinations on steam, air and hydraulic vessels and supports class survey attendance during periodical and special surveys. Tianjin Ocean Shield holds service supplier recognition under the American Bureau of Shipping for relevant categories, allowing reports issued from its LSA, davit and pressure vessel campaigns to be considered during periodical, intermediate and special surveys carried out by attending surveyors. The Tianjin base provides convenient access to bulk carriers, tankers, container ships and general cargo tonnage that call at Tianjin Xingang, Caofeidian and other Bohai terminals, with technicians mobilising to terminals, anchorages and adjacent repair yards. Customers include shipowners, ship managers and operators that need documented compliance work on safety-critical equipment fitted to commercial tonnage trading through northern Chinese ports and the broader Yellow Sea region. Combined LSA, davit and pressure equipment scope under ABS recognition supports owners coordinating multi-discipline attendances during a single port call.
