Exploring subsea dynamics: A comprehensive review of underwater pipelines and cables

Abstract

The development of marine resources is intrinsically linked to the utilization of various marine equipment. Among these, marine pipelines and cables are crucial for the exploitation of deep-sea oil and gas resources. Mooring cables, marine towed cables, marine umbilical cables, submarine cables, and marine pipelines are typical slender and flexible marine components. These slender marine flexible members present various dynamic challenges during laying, installation, and in-position operation. Facing these challenges, scholars from China and around the globe have explored theoretical, numerical, and experimental solutions to these challenges. The conclusions need to be condensed to improve their practical and academic value for engineering applications. This paper summarizes the explorations and provides general design methods and concepts of marine pipelines. Additionally, this paper looks forward to the future development trend of marine pipelines in engineering applications as well as theoretical research. The aim is to provide a reference for the research of underwater pipelines and cables.
