Protec Marine Service Co., Ltd is a marine safety service contractor located in Jiangyin, Jiangsu Province, on the lower Yangtze River, serving vessels at Jiangyin Port, the Zhangjiagang, Taicang, Changshu and Nantong terminals and the wider Yangtze River Delta port cluster. The workshop is configured around the periodical SOLAS scope for life-saving appliances and fire-fighting equipment, with class-related tightness work added to cover repair-period surveys. Field crews perform annual and five-yearly servicing of inflatable liferafts, conventional and totally enclosed lifeboats, rescue boats, davits and launching appliances, hydrostatic release units, immersion suits, lifejackets and lifebuoys. Fire-safety services cover portable-extinguisher recharging and hydrostatic testing, performance checks on fixed CO2, foam and water-spray installations, fire hose and hydrant pressure testing and breathing-apparatus servicing for EEBD and SCBA sets, together with lifting appliance and gear surveys, ultrasonic hatch cover tightness testing and watertight integrity verification of doors and penetrations. Protec Marine is listed by several IACS classification societies as a recognised service supplier, with firm-name approvals seen under ABS, Bureau Veritas, China Classification Society, Korean Register, Lloyd's Register and RINA across the relevant LSA, FFE, lifting and tightness categories. Inspection reports issued from Jiangyin are accepted for SOLAS-mandated annual, intermediate and five-yearly surveys on merchant tonnage flagged with administrations that recognise these IACS members, including vessels working the Yangtze River and the East China Sea coastal trades. 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. Spare parts for liferaft canisters, lifeboat release-hooks, hydrostatic release units, extinguisher refills, EEBD and SCBA composite cylinders and CO2 control-station components are held in workshop stock, allowing immediate replacement of expired or non-compliant items at the time of inspection.
