Guangzhou Shunhai Maritime Technical Service Co., Ltd. is a marine technical services contractor based in Guangzhou, Guangdong Province, serving vessels calling at the Pearl River Delta ports of Guangzhou-Nansha, Huangpu, Shenzhen-Yantian, Shekou, Zhuhai-Gaolan, Dongguan, Foshan, Zhongshan and Hong Kong. The workshop holds inventory and tooling for life-saving and fire-safety servicing covering inflatable liferafts, lifeboats, rescue boats, davits and launching appliances, hydrostatic release units, immersion suits, lifejackets, lifebuoys, portable extinguishers, fixed CO2, foam and water-spray installations, fire hoses and hydrants, and breathing-apparatus EEBD and SCBA sets. Radio and navigation work covers annual GMDSS performance testing, GMDSS equipment service and AIS annual inspection, while class-related scopes include ultrasonic hatch cover tightness testing, watertight integrity testing, hull ultrasonic thickness gauging, pressure vessel inspection, lifting appliance and gear surveys and class-acceptable underwater hull inspection coordinated with diving partners. Shunhai is a long-standing recognised service supplier of multiple IACS classification societies, with firm-name approvals seen under Bureau Veritas, RINA, ABS, China Classification Society, ClassNK, DNV, Indian Register of Shipping, Korean Register and Lloyd's Register, allowing inspection reports and certificates issued at Guangzhou to be used for SOLAS, MARPOL and class-related surveys on merchant vessels flagged with administrations that recognise these classification societies. Reports are routinely accepted by Chinese, Panamanian, Liberian, Marshall Islands, Hong Kong and Singapore registries for vessels working the South China coast. 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.
