Jetty Balloon Fender Installation

At a primary commercial cargo jetty in the deep-water port waters of Karachi, Alsons Hardware engineered, assembled, and installed high-capacity pneumatic marine balloon fenders to mitigate structural concrete fatigue caused by the berthing impacts of multi-thousand DWT cargo carriers. Degraded existing dock buffers were transmitting dangerous kinetic shockwaves directly into reinforced concrete jetty pilings, threatening catastrophic shear cracks along the berthing face.

Our maritime engineering team supplied heavy-duty 50 kPa and 80 kPa pneumatic balloon fenders equipped with full aircraft tire net harnesses, Grade 80 hot-dip galvanized mooring chains, and high-tensile drop-forged shackles. Each fender was calibrated to exact PIANC marine energy absorption curves and secured with upper and lower tethering bridles engineered to float smoothly across 4.5-meter tidal swings without chain binding or twisting, cutting hull impact forces by 85%.

This commercial cargo jetty fender installation represents Alsons Hardware's extensive marine contracting and harbor defense portfolio across Pakistan. Beyond pneumatic balloon fender deployments, our specialized marine engineering divisions provide turnkey port infrastructure services—including rubber cone and cell fender installations, dolphin pile refurbishment, mooring bollard pull proof testing, dockside steel corrosion protection, and berthing face structural rehabilitation across Karachi Port Trust (KPT), Port Qasim Authority (PQA), Gwadar Port, naval dockyards, and offshore industrial terminals nationwide.
