Samyoung Ship Service (Ningbo) Co., Ltd 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, with major container, crude-oil and bulk facilities at Beilun, Daxie and surrounding terminals serving ocean-going commercial tonnage. The firm provides on-board technical attendance focused on lifesaving equipment service work for commercial vessels calling Ningbo-area berths and the surrounding anchorages used for crew change, bunkering and routine maintenance during ordinary commercial calls. Lifesaving services cover lifeboat and rescue boat annual and five-yearly servicing, including hoist trials and load tests on associated davits, liferaft annual inflation and pressure testing including gas-cylinder inspection and renewal of survival pack contents, and overhaul of associated release gear and on-load hooks together with hoist wires and falls. Reports from servicing campaigns are prepared in formats accepted by attending classification surveyors, and field teams attend at berth and anchorage with calibrated test gauges, hydrostatic test rigs and authorised manufacturer spare parts for routine renewals, including approvals supporting Korean-built lifeboat and rescue boat product ranges installed on Korean-owned and overseas tonnage. Samyoung Ship Service holds service supplier recognition by the Korean Register, reflecting its Korean-affiliated ownership, and allowing servicing records to be considered during periodical, intermediate and special surveys on commercial tonnage trading through the East China Sea. Customers include shipowners, ship managers and port agents arranging short-stay maintenance attendances at the Ningbo-Zhoushan terminals during commercial calls.
