Study on the Dynamic Responses of a Large Caisson during Wet-Towing Transportation

Large caissons are extensively applied as deep-water foundations in marine engineering. In fact, generally prefabricated and transported to project site by wet towing. Motion responses of large those occurring during the towing process were investigated, CO2 emissions under various conditions calculated. These all considered ensure safety environmental protection. The caisson resistance coefficient was simulated via Ansys Fluent software. effects towrope length, speed, drift depth on motion combined action wind wave evaluated AQWA Maximum heave value dominantly affected rope length draft depth, its fluctuation highly influenced speed depth. However, above mentioned factors had insignificant influences pitch response. When existed, tension rapidly increased from zero a constant that depended achieving this stable phase towrope.
