Shanghai Jiangjia Shipping Technology Co., Ltd. is an independent shipping technology supplier based in Shanghai, supporting merchant vessels calling at the Yangtze River Delta with a focused range of measurement and inspection services. The Jiangjia team is profiled on the ShipServ marine supplier marketplace and is recognised by major classification societies including RINA, Bureau Veritas, DNV, Korean Register, Lloyd's Register, ABS and ClassNK, allowing its measurement reports to be used in support of statutory surveys and class verifications. Engineers carry out shipboard noise level surveys under IMO MSC.337(91) for new and existing vessels, together with whole-ship vibration measurement and rotating-machinery vibration analysis and balancing in line with ISO 10816 criteria for main and auxiliary engines, shaft lines, pumps and turbochargers. The team also undertakes inspection and functional testing of fire detection and alarm systems, supporting periodical SOLAS Chapter II-2 verifications and fault-finding on heat, smoke and flame detector loops. Ballast water management system commissioning testing and service-engineer support are offered for vessels subject to the IMO Ballast Water Management Convention, covering D-2 indicative analysis and BWMS sampling at ballasting and de-ballasting operations. Underwater hull inspection in lieu of drydocking is delivered through partner diving contractors, providing in-water survey reports acceptable to class. Shanghai Jiangjia mobilises technicians to anchorages, terminals and repair yards across Shanghai, Ningbo, Zhoushan and other Yangtze River Delta ports, with equipment calibrated under traceable national standards to ensure consistent measurement and reporting across multi-ship management fleets and across long-term performance-monitoring programmes for owners.
