Dynamic Response Analysis of Super Cone SCN 1800 Type Fender System Due to Ship Operating Load Behavior

LNG bunkering is the provision of fuel to ships operatingOperating condition in the maritime transportation sector. This has led to the construction and development of improved bunkering port facilities. A good port requires a good ship berthing structure to protect the structure from the impact of the ship's body on the pier, by means of using fendersFender system. This paper analyzedAnalyze the fender-type of super cone SCN 1800 structure due to berthing forces and environmentalEnvironmentalloadsLoads when the LNG-fueled dry bulk carrier ship operates. The analysis of the berthing forces is carried out by analytical methods, while the forces from environmentalEnvironmentalloadsLoads are numerically treated in time domain simulation by using the finite element method. The analytical results showed that the berthing angle and speed of the ship are allowed if the reaction force does not exceed the reaction capacity of the fenderFender. The normal ballast conditions for ships are 4° and 0.180 m/s, while for ships, the full load conditions are 6° and 0.105 m/s. The maximum fender reaction force obtained from the time domain simulation when the ship operates due to environmentalEnvironmental loads is 2,325 kN. After ten years, the fender's absorption capacity has decreased by 20%. Consequently, the research result discloses that the fender structure still accomplishes the capacity of a fenderFender response force partly due to the dynamic force of the environmental load.
