...-frequency motions and wave asymmetry factor considered in the simplified approach (DNVGL-RP-C205). This paper investigates the impact of revised guidelines for semisubmersible design by comparing air gap predictions from simplified approach, revised OTG13 guidelines, and model test data. drilling semi...

Paper Number: OTC-28895-MS
...Abstract Abstract In case of conventional shallow-draft semisubmersibles, unacceptably large riser stroke was the restricting factor for dry-tree-riser-system development. Many developments to address this issue have focused on using larger draft and size with extra heave-damping plates, which...

...Abstract Abstract Semisubmersible platforms are good candidates for hydrocarbon exploration and production in the Gulf of Mexico (GoM) and elsewhere. These platforms are a preferred choice for deep-water applications involving higher design throughput. A dry tree application of semisubmersible...
