Submarine pipeline stability under currents and waves action

Abstract

Pipelines are widely used in recent decades because their eco-friendliness, safety and profitability of transportation. Their length can be more than hundreds and thousands of kilometers. Submarine pipelines got wide distribution. Their constructing must comply with regulatory documents. But even it cant guarantee no problems during operation. This study contains review of the different research, connected with floating of a submarine pipeline problem. Information about conducted research and their conclusions is summarized in this paper. Direction for the future investigations is shown. Submarine pipelines are subjected to vertical movement (floating). Pipeline ballasting method is used to avoid this situation. Ballasting by loading bags is considered in this article. This study contains review of the different research, connected with floating of a submarine pipeline problem. Calculations required for the correct selection of the loading bags weight are performed, possible reasons for floating are described. This article will be useful for submarine pipeline designers.
