Abstract


With the development of offshore oil , submarine pipeline as an important part of the offshore oil storage and transportation system , has been widely used. Laying of submarine pipeline construction technology complex , high- risk . And an important part of the pipelay construction pipeline transport to target sea area , the pipeline will be in the process of wind , waves and currents . It is extremely important to ensure the safety of the pipeline in the transportation and laying process and reduce costs , to determine the pipeline by environmental loads , calculation and analysis of the strength and stability of the pipeline . This article relying Luanda, Angola subsea pipeline projects were introduced , with a focus on the port of Luanda for some 600 meters of the bottom line of the refined oil terminals floating dragging method construction process , including construction methods in the construction process , the selection of the program , by undersea pipeline deformation and mechanics checking , as well as the place of the pipeline sinking stability analysis of the performance of the force . Mechanical calculations and analysis show that : The selected facilities Ⅱ arts to ensure the security of the submarine pipeline facilities Ⅱ away ; submarine pipeline strength , stability force performance to meet the requirements .
