Subsea Releases CFD

Subsea releases are a complex fluid modelling case in which gas and condensate among other components are released at high pressure  at the seabed. The release including the gas which is composed of bubbles that tend to break up while being transported upwards under the influence of buoyancy and transported laterally by the currents which has varying speeds and differing directions at various depths below the surface. 

The gas then is released from a typically wide area at the sea surface, mixing with the air and forming a flammable and/or toxic cloud. 

Other outputs include the forces on the capping stack as it is lowered to the sea bed. These  include drag and lift  as well as torsion. The forces are important and calculated for operators as guidance for the lowering of the capping stack.

Advanced Analysis provide comprehensive modeling solutions to accurately predict the behavior of the released fluid and its interaction with the environment. This allows for the development of effective strategies for spill prevention, response, and mitigation.

Our subsea releases CFD capabilities include:

  • Detailed modeling of fluid properties and behaviors

  • Accurate representation of subsea geometries, including risers, pipelines, and wells

  • Analysis of fluid flow dynamics and dispersion patterns

  • Assessment of potential environmental impacts

  • Development of emergency response plans


With our subsea releases CFD capabilities, Advanced Analysis can provide clients with advanced modeling solutions to minimize risks and ensure safe and environmentally responsible operations.
