    Dual BOP - a necessity?!

    Google "drilling contractor dual bop" and click on the top article in drilling contractor magazine, which is called: Dual BOPs: When one just isn’t enough.
    Makes interesting reading
    BOP = blow out preventer.
    Having two instead of one more ore less halves down time between drilling of wells

      Have you ever seen a seven ram BOP in person? Each of those things is the size of a three story building. Each of the rams should be able to stop the flow of oil, so a seven ram unit already has multiple backup systems. It does make since to have a backup, so you can recondition the first one while the second one is used in the drilling operations.

        the new ship will have two

        STX Offshore & Shipbuilding (STX O&S) has won a $672m contract from Norway-based Sigma Drilling to build one BT-UDS dynamic-positioned ultra deep water (UDW) drillship.

        The contract also includes options for four additional drilships, which would bring the total order amount to approximately $3.5bn.

        With a length of 230m, breadth of 38m and height of 18.4m, the vessel will have 40,000ft drilling depth and will be capable of drilling in water depths of 12,000ft.

        The new UDW drillship will be equipped with a pair of 15,000 psi blow out preventer (BOP) stacks, which can be upgraded to 20,000 psi BOP.

        If upgraded, the vessel would be one of the first 20,000 psi drillships in the world.

        BOP is a core piece of equipment that prevents the explosion of high-pressured gas, water and oil out of wells during drilling operations.
