DEVICE TO INTERRUPT OIL AND/OR GAS FLOW FROM A POISON, IN PARTICULARLY WHERE THE INTERCEPTING AND SAFETY OF THE BLOWOUT TYPE PREVENTED FOR SUBACCESS POWERS IS TESTED

摘要

The present invention relates to a device and to a method for blocking the outflow of a pressurized fluid from an underwater well, in particular, for blocking the outflow of crude oil and/or of natural gas, for carrying out an operation of closure of the well. In particular, the invention relates to a device and to a method for quickly stopping the flow and closing the well in case of incident and/or in case of fault of emergency shut-off devices of the underwater well, such as blowout preventer (BOP) systems, in order to reduce harm to the environment and economic losses due to fluid outflow from the well.
