Abstract

The impact load caused by ships could be converted into a tolerable value for the floating structures and berthing ships by placing the fenders next to them. The effect of two widely used fenders is investigated in this study on barges with high-strength concrete material, including pneumatic fenders (Ocean guards) and cellular fenders with conical cross-sections. It is worth mentioning that the impact load in this paper is considered for the Jask marine area in Iran with the probability of passing different ships with various tonnages. Therefore, the fender system and the impact load on barges were determined for floating ships up to 45000 tons with a safety factor of two based on critical conditions. Statistical results illustrated that pneumatic fenders are an appropriate choice for concrete barges compared to cellular fenders with conical cross-sections due to the low out-of-plain behavior of concrete shell elements and higher effective area after impact.
