Flexcom - Floating Hose

This video illustrates a Drilling Riser modelled using Flexcom, which is typical of deepwater exploration systems deployed in regions such as the Gulf of Mexico. This model simulates an emergency disconnect scenario, following failure of the dynamic positioning system on the drillship. In such situations, the riser is quickly disconnected from the wellhead to prevent any potential damage.

Although Flexcom can provide an approximate simulation of the disconnect event and subsequent riser recoil, a more comprehensive simulation may be performed using DeepRiser, which specialises in the analysis of top-tensioned risers. DeepRiser provides a detailed hydro-pneumatic tensioner, which models all the major hydraulic and pneumatic components. It can model each tensioning cylinder independently, and can simulate the behaviour of the anti-recoil control system.
