Activities:
comments: Sat TBC ROV panel A in "primary unlock" 2-1-1 and RIH with PR another 10-15 cm. Sat TBC ROV panel A in "primary lock" 2-1-2. Sat down 15 mT on PR. Pressured up through TBC port A to 3000 psi and observed silver band alignement of indicator rods above TBC top cap. Silver band was completely aligned. Sat TBC ROV panel A in "parked position".

Performed 10 mT overpull test to 107 mT to confirmed that TBC was locked. Ok. Sat TBC ROV panel B in "lower dog flush" x-1-1 and removed dummy hot-stab to be able to observe possible leak.
