Wave Impact Effects

Load predictions on marine structures, such as oil production platforms in random storm waves are critical. Physical mechanisms leading to water on deck and bow flare slamming and the resulting responses, must also be analyzed. FLOW-3D provides predictions of water presence on the deck, impact load on structures and large-scale wave propagation.

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.
