Figure F8. Schematic of the seafloor and borehole installation for Hole 1150D. The reentry cone is installed and the casing cemented in. The instrument string is coupled to 4-in casing pipe and to the hanger/riser. This is inserted into the hole using the drill string. Cement is pumped through the instrument string and up into the cased part of the hole. The battery frame is then lowered onto the reentry cone, and the hanger/riser is then decoupled from the drill string. mbrf = meters below rig floor, TD = total depth.
