Tru-Tech Marine (Shanghai) Co., Ltd. is a marine safety service contractor located in Shanghai, serving vessels at Waigaoqiao, Yangshan, Wusong and the wider Yangtze River Delta port cluster. The workshop is built around the full SOLAS scope for life-saving and fire-fighting equipment, with class-related hull and radio work added to cover voyage-repair and dry-dock requirements. Periodical servicing is performed on inflatable liferafts, conventional and totally enclosed lifeboats, rescue boats, davits and launching appliances, hydrostatic release units, immersion suits, lifejackets and lifebuoys. Fire-safety scope covers recharging and hydrostatic testing of portable extinguishers, 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 cylinder pressure-vessel inspection. Radio and navigation work includes annual GMDSS performance testing, GMDSS equipment service and AIS annual inspection. Class-related scope covers lifting appliance and gear surveys, pressure vessel inspection, ultrasonic hatch cover tightness testing, watertight integrity verification and class-acceptable underwater hull inspection through approved diving partners. Tru-Tech Marine is listed by the Bahamas Maritime Authority as a recognised service provider and is approved by RINA, ABS, Bureau Veritas, Indian Register of Shipping, Lloyd's Register, China Classification Society, DNV and Korean Register for the relevant LSA, FFE, radio and class-related categories. Reports issued at the Shanghai workshop are accepted for SOLAS-mandated surveys on merchant tonnage flagged with administrations that recognise these IACS members. 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.
