Immersion crude oil export hoses are about to be applied in the South China Sea. Due to the fact that submerged export hoses have not been applied in Chinese waters before, in order to ensure that submerged export hoses do not sink during towing to designated locations, a finite element analysis model was established based on submerged export hoses and the sea conditions in the South China Sea to analyze the export hose string under different towing conditions. The results showed that there is a risk of sinking of export hoses under some operating conditions.

摘要

Immersion crude oil export hoses are about to be applied in the South China Sea. Due to the fact that submerged export hoses have not been applied in Chinese waters before, in order to ensure that submerged export hoses do not sink during towing to designated locations, a finite element analysis model was established based on submerged export hoses and the sea conditions in the South China Sea to analyze the export hose string under different towing conditions. The results showed that there is a risk of sinking of export hoses under some operating conditions.
