Ningbo Xinye Marine Safety Equipment Service Co. Ltd. was founded in 1984 and is based in Ningbo, the eastern Zhejiang port that forms part of the combined Ningbo-Zhoushan port complex, the world's busiest port by cargo throughput. The firm concentrates on liferaft and fire-fighting equipment service work performed onboard merchant vessels and at shore service stations supporting deep-sea, coastal and inland tonnage calling Ningbo-area berths and the surrounding archipelago anchorages used for crew change and routine maintenance. Liferaft annual servicing includes inflation testing, pressure checks, gas-cylinder inspection, valve overhaul and renewal of survival pack contents, with overhaul authorisations from major manufacturers including the Korean firm Samgong and the Danish firm Viking, alongside authorisations from several Shanghai-based liferaft makers covering Dacheng, Long and Hai'an product ranges. Fire-fighting equipment work covers portable extinguisher recharge, fire main and hydrant pressure testing, foam and dry-powder system maintenance, inspection and recharge of fixed CO2 installations and routine renewal of associated consumables. Ningbo Xinye is approved by the Maritime Safety Administration of the People's Republic of China for liferaft service and operates an ISO 9001-certified quality system originally accredited by CSQA, reportedly among the first in Zhejiang Province to gain that recognition. The firm holds service-supplier recognition by Bureau Veritas, Lloyd's Register, DNV, ClassNK, ABS, RINA, the Korean Register, GL and the Russian and Indian registers, allowing servicing records to support class periodical, intermediate and special surveys as well as flag-state inspections on tonnage trading through the East China Sea and beyond.
