Description

A method for anti-disturbance oil transportation with floating hoses on the sea surface

Technical field

The invention relates to a maritime ship oil transportation technology, and in particular to a method for anti-disturbance oil transportation with floating hoses on the sea surface.

Background technique

About 71% of the ocean is a treasure house of human resources and energy. According to incomplete statistics, 135 billion tons of oil and 140 trillion cubic meters of natural gas have been discovered in the ocean. Our country also has abundant marine resources. The proven oil is estimated to be about 24 billion tons, and the natural gas resources are estimated to be 14 trillion cubic meters. As my country's offshore oil and gas exploration and production further increases, more oil and natural gas will come from offshore oil terminals in the future. Offshore terminal refers to the docking place for tanker mooring, berthing (DP positioning operations), and cargo transfer. Common offshore oil terminals are divided into four types: fixed terminals, single-point mooring systems, multi-buoy mooring systems, and turret mooring systems. Shuttle tankers are special tankers designed to travel from offshore terminals to coastal refineries. However, because of their complex loading and power systems, the cost is several times that of traditional tankers, and the requirements for operator qualifications are high. Therefore, using existing tankers to transport offshore terminal petroleum products is still the priority for most domestic liquid cargo transportation companies.

The liquid cargo loading and unloading operations of offshore oil tankers leave the floating oil pipeline and float on the sea all year round. They are extremely susceptible to environmental loads such as wind, waves, and currents. Problems such as stress concentration, fretting fatigue, and fracture failure may occur, especially In the case of high winds and strong waves, during oil transportation operations, it will also affect the normal flow of oil in the floating hose. Especially in the middle section of the floating hose, the impact of wind, waves and currents is more obvious, causing up and down disturbances. The magnitude is huge. In oil transportation operations, how to reduce and reduce the impact on oil transportation operations is an urgent problem that needs to be solved.
