Zhoushan Wisdom Marine Co., Ltd. is a marine safety service contractor located in Zhoushan, Zhejiang Province, serving vessels at the Zhoushan, Ningbo-Zhoushan, Liuheng, Putuo and Daishan anchorages and at major repair yards in the East China Sea cluster. The workshop is configured around the full SOLAS scope for life-saving appliances and fire-fighting equipment, with additional capability in radio, hull-survey and tightness work. Periodical servicing is provided for 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 EEBD and SCBA servicing. The team also handles design, prefabrication, installation and commissioning support for fixed fire-fighting systems on board. Radio and navigation work covers GMDSS annual testing, GMDSS equipment service and AIS annual inspection, while class-related scope includes lifting appliance and gear surveys, pressure vessel inspection, hull ultrasonic thickness gauging, ultrasonic hatch cover tightness testing, watertight integrity verification, ro-ro door inspection and class-accepted underwater hull inspection through approved diving partners. Wisdom Marine is listed by the Liberian Registry as an authorised lifeboat service provider under reference ASP-354 and is recognised by RINA, ABS, Bureau Veritas, DNV, Indian Register of Shipping, Korean Register and Lloyd's Register for the relevant categories. 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.
