When a problem occurs subsea and underground pressure forces oil or gas into the wellbore the Blow Out Preventer (BOP) is required to operate quickly preventing damage to surface modules and the surrounding environment.

If the BOP cannot be operated remotely, one of the few remaining options to actuate the BOP is by using ROV intervention. For this to occur quickly and safely the intervening ROV requires to deliver very high flow fluids at high pressure.

The Forum Blow Out Preventer Actuating Tool (BOP-AT) is designed to be operated by a work class ROV, delivering hydraulic fluid in two stages.

The first stage is high flow low pressure to activate the BOP rams. Once the BOP cutting tool contacts the drill string the second stage is manually activated.

This is high pressure low flow that allows the BOP to shear the drill string and fully close the BOP to seal the well bore.
