Haper Marine Co., Ltd. is registered in Huizhou, a coastal city of Guangdong Province on the South China coast that lies within reach of the Pearl River Delta shipping lanes and the major terminals at Yantian, Shekou and Nansha. The company concentrates on life-saving appliance and fire-fighting equipment service work performed onboard merchant vessels calling at South China ports and at the nearby anchorages used for crew change, bunkering and routine maintenance. Periodical testing of lifeboats and rescue boats, davits and launching systems, liferaft annual servicing and load tests on associated hoist arrangements form the core of the lifesaving scope, alongside annual renewal of on-load release gear, hoist wires and survival pack contents. The fire-safety practice covers portable extinguisher recharge, fire hose and hydrant pressure testing and inspection and maintenance of breathing apparatus such as EEBD and SCBA sets used during enclosed-space drills and emergency response training. Field technicians also attend lifting appliance and gear surveys, supporting the issue of cargo-gear certification under SOLAS chapter VI and ILO requirements. Service reports from Haper Marine are issued in formats accepted by attending classification surveyors, and the firm holds service supplier recognition under Bureau Veritas and the Korean Register, allowing inspection records to be considered during periodical, intermediate and special surveys carried out on commercial tonnage. Customers are primarily shipowners, technical managers and ship agents arranging maintenance attendances in the Huizhou and Shenzhen areas, with calibrated test gauges, hydrostatic test rigs and spare parts dispatched to vessel berths and anchorages so that safety equipment is returned to class-compliant condition without prolonging vessel turnaround.
