Zhejiang Qiuzhen Fire-fighting Equipment Co., Ltd. is a marine safety service company based in Zhoushan, Zhejiang Province, serving vessels calling at the Zhoushan, Ningbo-Zhoushan and wider East China Sea port cluster. The workshop and stores are located in Putuo District close to the Shenjiamen anchorages, allowing technicians to reach vessels at anchor and at the main repair berths with limited transit time. The technical scope covers periodical servicing of life-saving appliances such as lifeboats, rescue boats, inflatable liferafts, davits and launching gear, immersion suits, lifejackets and lifebuoys, and the full range of fire-fighting equipment including portable extinguisher recharging, fixed CO2, foam and water-spray installations, fire hose and hydrant pressure testing, and breathing-apparatus servicing for EEBD and SCBA sets. The team also handles radio and navigation work covering annual GMDSS radio tests, GMDSS equipment maintenance and AIS annual inspection, together with class-related hull work such as ultrasonic hatch cover tightness testing, watertight integrity verification and pressure vessel inspection. Qiuzhen has been listed by several IACS classification societies as a recognised service supplier, with firm-name approvals seen under ABS, Bureau Veritas, China Classification Society, Indian Register of Shipping and RINA for the relevant LSA, FFE and radio categories. Class-witnessed reports issued by the firm are accepted for SOLAS-mandated periodical surveys on merchant tonnage flying flags that recognise these classification societies, supporting compliance work throughout the Zhejiang coastal trade. Coordination between LSA, FFE and class-related work scopes is handled from one work order so multiple periodical items can be closed during a single port call, reducing off-hire time for owners and managers.
