comments: Lifted PR string, removed landing plate from tenion joint and lowered it down to top of riser landing guide funnel (RLGF).  Hook load 97 mT. Continued lowering PR until TBC was 10 cm above VGX gasket. Removed RLGF and oriented TBC ROV panels. Landed TBC and sat down 15 mT weight. Launched hotstab down to seabed, attached to guidewire. Removed dummy hot stab and installed hydraulic hot stab into receptacle at top of TBC using ROV.
