Olmsted_ARV_Anti-Recoil_Disconnect_Valve

The global standard from the world leader in riser disconnect recoil control.

Over the decades, Oilgear's Olmsted group has pioneered the art of valving for motion compensation applications. The Olmsted Anti-Recoil Valve (ARV) is the global standard for control of offshore riser tensioning systems, and safety during emergency disconnect sequences (EDS).

During an emergency disconnect event, this is a system that, by means of electrical and hydraulic controls, adjusts the opening of the Olmsted valve based upon the position of the tensioner cylinder’s rod.

For different tension and depth scenarios, the control algorithm varies.  The control algorithm is determined by way of system simulations.

The modern anti-recoil valve has two core functions:

  • Protection against recoil caused by a parted riser
    • Rapid response that stops the flow from the accumulators to the cylinders
  • Controlled arresting of the system during an emergency disconnect event
    • Using an algorithm derived from system-level simulations, the ARV performs a metered closure
