comments: Took MWD survey. Stepped up pump and rotation to obtain drilling parameters. Standpipe pressure fell rapidly when reaching 130 bar. Unclear indications. Attempted to pump and observed that pop off valve had triggered. Mud returns from pop off ventline went down to pit #15 which overflowed pit and pit room. Halted operation.

comments: Mechanical pop-off valve had taken damage and nedeed to be replaced. No spare available. Blinded off line with lo-torqe valve and lined both mudpump#1 and mudpum#2 pumps to one pop-off valve. Mudpump #3 still dedicated for barite injection in spudcans. Meanwhile troulble shooting on pop-off, circulated with 800-1000 lpm and resiprocated string.
