IMPA Code 232411 Pneumatic Fender
Hongruntong Marine, a trusted leader in marine engineering solutions, proudly offers high-performance Pneumatic Fenders designed to safeguard vessels and port infrastructures during berthing, mooring, and offshore operations. Engineered with premium-grade rubber and reinforced by multiple layers of synthetic fabric, our pneumatic fenders leverage compressed air technology to deliver unmatched energy absorption, durability, and operational efficiency. Ideal for demanding marine environments, these fenders are rigorously tested to meet international standards, including OCIMF, ensuring reliability and safety across all maritime applications.

Key Features & Advantages
Advanced Energy Absorption: Utilizing air compression principles, our fenders deform dynamically upon impact, efficiently dissipating kinetic energy while maintaining low reaction forces to protect vessel hulls and docking structures.
Robust Construction: Built with UV-resistant, abrasion-proof rubber and reinforced fabric layers, Hongruntong’s fenders withstand extreme weather, saltwater corrosion, and heavy loads for extended service life.
Modular Customization: Available in diverse sizes (DN500 to DN4500) and pressure ratings, our fenders are tailored to suit specific project requirements, from small harbors to large-scale LNG terminals.
Eco-Friendly & Cost-Effective: Lightweight design simplifies installation and reduces transportation costs, while minimal maintenance needs and reusable components align with sustainable marine practices.
Smart Safety Systems: Equipped with pressure relief valves and real-time monitoring options, our fenders ensure optimal performance and safety during critical operations like ship-to-ship transfers.
Applications
Hongruntong Marine’s pneumatic fenders are the preferred choice for:
Offshore Energy Projects: LNG carrier berthing, floating oil platforms, and subsea operations.
Commercial Ports & Terminals: High-traffic container ports, bulk cargo docks, and tidal zone facilities.
Ship-to-Ship (STS) Transfers: Safe mooring during fuel transfers or cargo operations in open waters.
Military & Emergency Use: Rapid deployment for disaster relief vessels or naval operations.

FAQ
Q: What does IMPA Code 232411 mean and do you supply fenders to this specification?
A: IMPA Code 232411 identifies pneumatic fenders in the IMPA procurement catalogue. Hongruntong Marine supplies pneumatic fenders that match this classification and can provide product specifications, material certificates and compliance documentation on request.
Q: What materials and construction methods are used? Are these fenders suitable for STS operations?
A: Our pneumatic fenders use a multi-layer construction: an internal inflatable bladder, reinforcement layers (cord or steel wire as specified), and a high-durability rubber outer cover. They are designed and manufactured for Ship-to-Ship (STS) operations, offering high energy absorption, low reaction force and proven resistance to abrasion and marine conditions.
Q: Can the fenders be customized? What about pricing and delivery?
A: Yes — Hongruntong Marine offers custom sizes, lifting fittings, working pressures, color options and accessory configurations to meet project requirements. We supply factory-direct, competitive pricing. Delivery schedules depend on order quantity and specification; please contact our sales team with your project details for a firm quotation and lead-time.
Q: What testing and certification do you provide before shipment?
A: Every unit undergoes factory inspection and testing, including pressure/air-tightness tests, dimensional checks and visual inspection. We supply test reports and material certificates with shipments. Third-party or class inspections (e.g., ABS, DNV) can be arranged upon request.
Q: What warranty, maintenance and after-sales support do you offer?
A: We provide warranty terms and a comprehensive after-sales program that includes spare parts, repair kits and technical support.
