Offshore Structures

Loads on marine offshore structures are largely determined by the detail of wave structure interactions in random sea states. FLOW-3D allows users to model non-linear interactions between floating structures under a variety of wave types and sea spectra, including JONSWAP, Pierson Moskowitz, and custom wave energy profiles.  FLOW-3D provides green water (water on deck) presence analysis, impact loads, and fully non-linear wave propagation analysis, as well and structure response in wave – structure – mooring systems.

The calm-water air gap under offshore platform decks is a critical design parameter and is determined by the required minimum air gap in extreme design conditions. FLOW-3D can be used to effectively in the prediction of air gap and wave impact loads on offshore platforms, tension leg platforms and semi-submersibles.

By modeling problems at full scale in the numerical environment, FLOW-3D allows engineers to by-pass the often delicate scaling issues associated with reduced-scale model physical basin testing.
