Analysis of jacket pile failure at breasting dolphin pile on berthing dolphin system

Abstract

The study evaluated the structural damage of the jetty pile jacket due to the impact load within operation days. The pile jackets on breasting dolphin (BD) were destroyed in front of pneumatic floating fender or leaning back direction. It observed that the failure was due to an impact load perpendicular to the pile and shear load between the floating fender and the pile jacket. The polyolefin material for pile jacket is not designed to hold any impact load from pneumatic fender vertically during docking. The pile jacket was installed to protect against to corrosion attack between tidal and splash zone. While the coal barge is docking on the jetty, the floating fender will crash and push the pile jacket by impact load at about 13.88 ton.m and swing press perpendicular to the breasting dolphin pile or shear load vertically. The installation of rack fender may practically protect the breasting dolphin pile and to back up currently pneumatically floating fender and the jacket pile.

Structure planning of 13470 DWT capacity jetty on Liquid Berth II Caspian Sea, Turkmenistan

“…Besides, the static load also covers the weight of any vehicle or engine that may be on the jetty. However, the force that the water, wind, or wave exerts on the jet is known as the dynamic load [8]. These dynamic loads can vary in intensity and direction, posing significant challenges in the design and construction of port structures.…”

The Strength Evaluation of 5600 DWT Double Hull Oil Tanker Subjected to Fender Load

“…When the fender deflected on absorb energy, raising the reaction force which forwarded to berthing structure and ship structure. Based on the literature study, the reaction force based on the fender caused failure on pile dolphins [1]. The fender reaction will be continuous to the ship as a pressure load.…”
