Abstract
It is well known that the installation loads during offshore pipeline installation are usually higher than the operation ones. FRP materials for offshore pipeline applications seems to be very promising due to their high strength, light weight, and excellent corrosion and fatigue resistance. However, during S-lay installation high bending stresses that may cause material failure or buckling take place. Due to the anisotropic nature of the multi-layered FRP pipelines, the permissible bending curvature is difficult to be estimated. Few published works have proposed the framework for bending stress calculations and have provided complex equations that is not convenient to be used. In the present work, an open numerical code in Mathematica® is offered for the first time. Numerical results for S-lay installation of representative pipelines are provided and commended.
期刊介绍：
Maritime Engineering publishes technical papers relevant to civil engineering in port, estuarine, coastal and offshore environments.
Relevant to consulting, client and contracting engineers as well as researchers and academics, the journal focuses on safe and sustainable engineering in the salt-water environment and comprises papers regarding management, planning, design, analysis, construction, operation, maintenance and applied research. The journal publishes papers and articles from industry and academia that conveys advanced research that those developing, designing or constructing schemes can begin to apply, as well as papers on good practices that others can learn from and utilise.
