Jiangyin Huada Marine Technology Company is based in Jiangyin, on the lower Yangtze in Jiangsu province, and delivers a broad mix of ship safety, tightness testing and in-water inspection services to merchant vessels calling at nearby ports and shipyards. The fire safety scope covers periodical FFE testing, recharging of portable fire extinguishers, examination of fixed CO2, foam and water-spray systems, pressure testing of fire hoses and hydrants, and maintenance of EEBDs and SCBA sets, with immersion suits and lifejackets inspected against SOLAS and IMO guidance. Life-saving appliance work includes overhaul of lifeboats and rescue boats and servicing of inflatable liferafts. Tightness scopes cover ultrasonic hatch cover testing and watertight integrity verification, and underwater inspection is offered for hull, rudder, propeller and sea-chest condition checks. Service approvals from ABS, BV, CCS, DNV and LR show that workshops, procedures and qualified personnel meet the criteria these classification societies set for the disciplines on offer. Coordinators in Jiangyin manage attendance schedules around port stays, anchorages and dry-dockings, with reports prepared in formats acceptable to attending surveyors and to owner, manager and superintendent departments. The proximity of the Huada base to Jiangyin, Zhangjiagang, Nantong and Shanghai shortens mobilisation times for vessels in the Yangtze region and supports consolidated attendance for LSA, FFE, tightness and in-water work during a single port stay or dry-dock window for owners, managers and crewing offices. Working with bulk carriers, tankers, container ships and general cargo tonnage trading through Yangtze ports, Jiangyin Huada also coordinates attendance for vessels arriving for dry-docking at regional yards, helping owners and managers consolidate LSA, FFE, tightness and in-water survey work into a single visit and align reporting with the vessel's class file and continuous hull and machinery records for ongoing maintenance planning.
