Shanghai Sure-safe Fire Equipment is a Shanghai-based ship service contractor with a primary focus on fire safety and life-saving appliance work, complemented by hull tightness, pressure vessel and in-water inspection services for merchant vessels calling at the city's container, tanker and general cargo terminals. Fire safety work includes 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. LSA work covers periodical testing, lifeboat and rescue boat servicing, liferaft annual inspection, and examination of immersion suits and lifejackets under SOLAS and IMO guidance. Ultrasonic hatch cover testing and watertight integrity verification support tightness compliance, while pressure vessel inspection covers compressed-air bottles, accumulators and similar onboard equipment. Underwater inspection is delivered by trained diver teams supporting in-water surveys. Service approvals from ABS, BV, CCS, DNV, KR, LR and RINA evidence that workshops, procedures and qualified personnel meet the criteria these classification societies apply across the disciplines covered. The technical team coordinates attendance around tight port stays and anchorages around the Yangtze estuary, with reports prepared in formats acceptable to attending surveyors and to owner, manager and crewing offices. The combination of fire safety, LSA, tightness, pressure vessel and underwater scopes under one technical roof supports consolidated attendance during single port calls. Working with bulk carriers, tankers, container ships and general cargo tonnage trading through Shanghai and adjacent Yangtze estuary ports, Shanghai Sure-Safe coordinates equipment logistics, qualified personnel and class liaison so attending teams deliver consolidated fire safety, LSA, tightness, pressure vessel and underwater scopes within available port time, aligning documentation with the vessel's survey programme and continuous safety equipment, hull and machinery records.
