Abstract: In this study, we analyzed the stress of the breasting dolphin jacket of a 300,000-ton crude oil port in an open water area with a water depth of 100 meters, under the effects of environments and ship loads. To achieve this, we took inspiration from offshore oil and gas pipeline platform structures, and combined the breasting dolphin structure with a pipeline frame that can support horizontal ship loads. We designed this structure using eight-leg columns and skirt pile foundations. To analyze the structure, we employed the finite element software ANSYS and conducted static analyses of the breasting dolphin structure under four different working conditions, based on environmental conditions and load combinations. The results showed that the displacement and stress on the pipeline frame structure reach its maximum during ship berthing, mainly appearing at the position of the main leg column near the mud surface, and the structural stress satisfies the allowable stress requirements. Our research indicates that using a pipeline frame structure for a large oil tanker terminal in 100-meter deep water is feasible, and it provides valuable insights for the selection and design of deepwater oil tanker terminal structures.
