Special issue: Safety of slender composite flexible structures in ocean engineering

The ocean is rich in non-renewable resources such as oil, natural gas and minerals, which lay solid foundation for the sustainable development of human society. The exploitation of Marine resources is inseparable from various kinds of slender composite flexible structures, such as umbilical cables, wind-power dynamic cables, bonded/non-bonded oil pipelines, deep-sea mining pipelines, LNG cryogenic hose, etc. The relevant structures are complex and expensive. Compared with the structures on land, they experience much harsher environmental conditions, and are subjected to a variety of random loads that change with time and space, including the combined action of environmental loads caused by wind, waves, ocean currents, tides, etc., and they are also threatened by sudden extreme events such as typhoons, earthquakes, and even explosions. In such circumstances, adverse factors such as nonlinear hydrodynamic behavior, fluid-to-solid coupling, complex loads on components, friction between layers, mechanical damage, material aging, machining and manufacturing defects, corrosion, marine organism attachment, and damage accumulation due to fatigue and crack propagation may lead to the performance degradation of the components and even the overall structure, affecting the safety and durability of slender composite flexible structures in ocean engineering. Structural failure not only causes huge economic losses, but also leads to serious environmental pollution and negative social impacts. Therefore, it is of great theoretical and practical significances to carry out safety analysis, design analysis, and manufacturing, test, operation and maintenance of the slender composite flexible structures in ocean engineering.

About the Journal:
China Ocean Engineering (COE), started publication in 1987, is a comprehensive academic bimonthly journal in English, indexed by several authoritative search databases, such as SCI-E, Ei, Scopus, AJ, CBST, CSA, and PA.

COE is concerned with all engineering aspects involved in the exploration and utilization of ocean resources. Topics regularly covered include research, design and construction of structures (including wharfs, dikes, breakwaters, platforms, mooring systems, etc.), instrumentation/testing (physical model and numerical model), wave dynamics, sedimentation, structural/stress analysis, soil mechanics, and material research.
