ABSTRACT: J type pipe laying method is the main laying pattern for deep-water pipeline. The exploitation of offshore oil and gas in China has stride forward into deep sea. However, domestic pipe laying technology in deep sea has yet to mature. This article adopts the stress analysis software CAESARII to do stress analysis of the process of submarine pipeline laying by J type, to study pipe’s deformation in the flowing water. It provides the corresponding theoretical basis for the submarine pipeline laying by J type, as well as the corresponding engineering value and guiding significance.
Keywords: Submarine pipe; J type; Stress analysis.
