§ 49 Well control equipment
Well control equipment shall be designed and capable of activation such that it ensures both barrier integrity and well control. For drilling where drilling mud returns to the facility and no blowout preventer is installed, equipment shall be installed with a capacity to divert gas and formation fluids away from the facility until the personnel have been evacuated. The equipment shall be installed for drilling through risers when the blowout preventer is installed on the seabed.
The pressure control equipment used in well interventions shall have remote-controlled valves with mechanical locking mechanisms in the closed position.
Well intervention equipment shall have a remote-controlled shear/blind ram as close to the christmas tree as possible.
Floating facilities shall have an alternative activation system for activating critical functions on the blowout preventer for use in the event of an evacuation.
Floating facilities shall also have the capacity to disconnect the riser package after the shear ram has cut the work string.
