... to exploring the effect of linear and non-linear stiffness extensible moorings on the FOWT system, which can be used for automated optimization of one variable for given constraints in the others. The proxy model was based on data from fully-coupled F.E. analyses of the DeepCwind semi-submersible FOWT...

... in shale gas productions is multi- stage hydraulic fracturing to form fracture networks for overcoming low permeability. This paper analyzes key parameters on shale gas production through sensitivity analyses and suggests an optimal hydraulic fracture design using a proxy model. Obtained key parameters...
