Chain Tyre Net Yokohama Pneumatic Fender
Hongruntong Marine’s Chain Tyre Net Yokohama Pneumatic Fender is a robust and proven solution for ship-to-ship (STS), ship-to-quay (STQ), and offshore terminal operations. Designed in accordance with ISO 17357-1:2014 standards, these pneumatic fenders are constructed with a durable reinforced rubber outer layer, an internal compressed air chamber for energy absorption, and a protective chain tyre net (CTN) that shields the fender from abrasion, impact, and external damage.
This type of fender is widely used for large tankers, LNG carriers, container ships, offshore platforms, and naval vessels due to its excellent performance in energy absorption and its ability to operate safely under various tidal and berthing conditions.
Key Features and Benefits
