Tangshan Ocean Mandarin Marine Engineering is a Tangshan-based marine service contractor supporting commercial shipping with safety, lifting and pressure equipment work across the Bohai Bay region. The firm holds service supplier recognition from ABS, Bureau Veritas, Korean Register, Lloyd's Register and China Classification Society, an approval set that gives its technicians access to a broad cross-section of internationally trading tonnage. Service activity is concentrated on life-saving appliance and fire-fighting equipment programmes including periodical LSA testing, lifeboat, rescue boat and davit servicing, liferaft inspection, fire extinguisher recharge, inspection and testing of fixed CO2, foam and water spray systems, pressure testing of fire hoses and hydrants and overhaul of breathing apparatus such as EEBD and SCBA sets. Immersion suits and lifejackets are inspected to SOLAS requirements. Tangshan Ocean Mandarin also undertakes lifting appliance and gear survey on shipboard cranes and derricks and pressure vessel inspection of boilers, air receivers and similar shipboard pressure equipment. Working from Tangshan gives the team practical access to the bulk and general cargo terminals of Caofeidian, Jingtang and the wider Bohai Bay, with attendance possible during cargo operations or short stays at lay-up berths. Procedures follow SOLAS chapter III, the LSA Code and IACS unified requirements for lifting and pressure equipment work, with equipment calibration and personnel qualifications maintained in line with the approving societies' expectations for service providers. Tangshan Ocean Mandarin coordinates LSA, fire, lifting and pressure equipment attendances within a single mobilisation when survey programmes allow, helping reduce port-stay overheads at the busy Bohai Bay terminals. Records of LSA test results, recharged fire-fighting units, lifting gear proof loads and pressure test data are retained for traceability, and reports are released in English where required for international clients running mixed-flag fleets.
