... ABSTRACT As an important green energy source, the presence of gas hydrates very demanding. They are only found on the seabed at a depth of kilometer. Large-scale exploitation of natural gas hydrates is likely to cause dramatic changes in the seabed topography, resulting in certain risks...

..., and conventional single-span analyses using approximate analytical expressions. It is demonstrated that including seabed topography and non-linear pipe-soil interaction effects in the static analysis has a significant effect on the outcome of the modal analysis for the cross-flow response. Multi-span behavior...

..., connecting the relevant locations. In the case of a complex seabed topography, it is not easy to identify feasible routes and to find the best choice. A lot of resources are put in the planning of the routes. The object is to find feasible paths that minimize the overall material and installation cost...
