Harvestec Service is a Shanghai-based contractor supporting commercial shipping with safety, navigation and inspection services across the Yangtze Delta and surrounding ports. The firm is recognised by ABS, DNV, IRClass, Korean Register, Lloyd's Register and Bureau Veritas, an approval set that allows attendances on vessels under most major class regimes. Core work centres on life-saving appliance and fire-fighting equipment programmes: periodical testing of LSA inventories, servicing of lifeboats, rescue boats, davits and liferafts, recharge and overhaul of portable fire extinguishers, inspection and testing of fixed CO2, foam and water spray systems, and pressure testing of fire hoses and hydrants. Breathing apparatus including EEBD and SCBA sets is serviced and pressure tested, with immersion suits and lifejackets inspected to SOLAS requirements. Harvestec also provides GMDSS annual testing and routine service, AIS annual inspections, underwater inspection in lieu of drydocking and pressure vessel inspection, broadening its scope for multi-discipline survey attendances during short port calls in Shanghai, Ningbo and adjacent terminals. Procedures follow IMO instruments including SOLAS chapter III for life-saving appliances and the LSA Code, plus class society guidance for testing and reporting. Equipment calibration and operator qualifications are maintained to the standards expected by the approving societies, enabling reports and certificates that are accepted into statutory survey records without rework. Harvestec coordinates LSA, fire, radio and inspection attendances within a single mobilisation where the survey schedule allows, helping owners and superintendents close out related survey items at one port call. Records of test results, recharged units and replaced components are retained for traceability, and reports are released in English where required for international clients managing multi-port maintenance programmes.
