With the failure of the "top kill" and "junk shot" to stop the flow of oil from the Deepwater Horizon well, BP will now attempt the Installation of a Lower Marine Riser Package (LMRP) Cap containment option. The LMRP is the top half of the blow out preventer (BOP) stack. The installation procedure first involves removing the damaged riser from the top of the BOP. A remote operated hydraulic shear will be used to make two initial cuts and then that section will be removed by crane. A diamond wire saw will then be placed to cut the pipe close to the LMRP and the final damaged piece of riser will be removed. The LMRP Cap is designed to seal on top of the riser stub. The seal will decrease the potential of inflow of seawater as well as improve the efficiency of oil recovery. Lines carrying methanol also are connected to the device to help stop hydrate formation. The device will be connected to a riser extending from the Discoverer Enterprise drillship.
