comments: Held tool box meeting in cement control room prior to pumping down the top-up pipe. Lined up to to pump down top-up pipe. Tested line and manifold 100bar/5 min. Stepped up pressure pumping at 50 l/min. At 52 bar (770 psi) differential, pressure bled of rapidly indicating burst disk rupture. Indications are that it is the shallowmost disk that ruptured.

comments: Slacked off to neutral weigt. Observed no movement on conductor. ROV confirmed inclinometer readings. Released CART by rotating 5 times to the right. Pulled CART above 30" housing. RB 1 std and dropped sponge ball and flushed DP with 2500 lpm for 5 min. POOH.

Meanwhile attempted to retract centralization rams in template funnel.  ROV did not manage to pull dummy hot-stab and broke handle on operation panel.

Pitch and roll readings :
