Description

-1- AN OFFSHORE DEEP-WATER DYNAMIC MOORING AND FOATING
TRACTION CRUDE OIL PIPELINE TRANSPORTATION METHOD Technical Field The invention relates to the field of crude oil transportation, in particular to an offshore deep-water crude oil pipeline transportation method. Background Art In the existing deep-water crude oil transportation, the shuttle tanker is an important tool to undertake the offloading task of the FPSO. Compared with conventional tankers of the same tonnage, the shuttle tanker has high construction cost and dead weight capacity of only 80,000-150,000 tons, but the conventional tankers have the dead weight capacity of up to 300,000-400,000 tons. Therefore, how to give full play to the advantages of the conventional tankers such as large number, low construction cost, high head weight capacity and low transportation cost in the large- scale, long-distance development and transportation of deep-water oil and gas resources and engage the existing oil tankers in the deep-water oilfield crude oil transportation operation without transformation is the revolutionary direction of the international crude oil transportation equipment technology and the objective needs for the offshore oil production and transportation chain to achieve safe and efficient production and reduce cost.
For long-distance transportation, some people use the shuttle tankers as the cargo transfer vessels to load crude oil into 300,000-400,000t ordinary oil tankers during the offshore deep-water crude oil transportation in order to increase the load capacity. After obtaining the crude oil from FPSO, the shuttle tanker moves to 300,000-400,000t ordinary oil tanker and delivers the crude oil to the ordinary oil tanker. To fill up the tank of the 300,000-400,000t ordinary oil tanker, it is necessary for the shuttle tanker to move and return, load and offload for 3-5 times, and pipe joints are required to be installed and dismantled for many times, so that the working efficiency is low. Moreover, the shuttle tanker and the ordinary oil tanker cannot be moored by anchoring as the shuttle tanker transports the crude oil in the offshore deep-water environment during shuttle between FPSO and the ordinary oil tanker. When the depth of water 1s more than 300 meters, the tanker body cannot be moored by anchoring. Besides the restriction of water depth, the shuttle tankers are also influenced by the
Do underwater materials. When the sea bottom is rock stratum, the tankers cannot be moored by anchoring. So there is a risk of collision when the tanker is floating. Therefore, how to safely transport is also a problem to be solved currently.
