Jacket pile is a corrosion protection system that is applied to ASTM 252 steel piles in the tidal and splash zone area of the Jetty. In this system the vessel is leaning on the breasting dolphin (BD). There has been damage to 9 new pile jackets installed and operated for several days in February 2018 on BD. damage occurs in the front position of the pneumatic fender direction of the vessel leaning. analysis is carried out using observation, inspection and simulation methods. the results of the analysis of the causes of damage to the jacket pile is due to vertical collisions and loads from the pneumatic fender. the visual simulation it can be predicted that when the ship rests near BD, the backrest will be held by a pneumatic fender, so that the floating fender will pound and press the pile jacket with mashing energy of 13.88 t.m, both in a shock, swing perpendicular and vertical to the pile BD. To prevent the recurrence of similar cases, it is recommended to use a BD Guard to protect the pile and jacket pile of BD from direct collisions and friction from pneumatic fenders and barges.
