comments: Made up 5 1/2" landing stand. RIH with production riser on 5 1/2" DP. Guided TBC into guide funnel while observing with ROV. Used ROV C-guide for stabbing TBC. Positioned ROV with manipulator camera pointing upwards in guide funnel cut out window. Observed TBC relative to VX ring and top wellhead while comming down with production riser. Stopped riser motion when ~10 cm TBC swallow was obtained.
