CBC News is reporting that the Stenna Icemax, drilling for shell, disconnected from and lost the drilling riser over the weekend. It is now lying on the seabed.
In anticipation of bad weather, all drilling fluids were stopped, the drill pipe removed, and the blowout preventer on the seafloor secured. The riser is the pipe that is used to control the Blow out preventer, Supply drilling mud, and contains the drill bit. It will disconnect form the drill ship if conditions get to rough, as it acts like a fixed tether to the ship.
The Stenna Icemax is currently drilling a well names Cheshire L-97. To date she has reached a depth of 6,669.09m, with a projected final dell depth of 7,532m. The water depth is 2,143.02m. weekly status reports indicate no progress was made on the well for 3 weeks in January – the reasons for this are not known.
