comments: Impact of the dropped 5kg part of the stabbing guide was estimated as 400 joules. 
Barriers were in place at the rig floor, no personal were on the rig floor, and the objects fell down within the Red Zone.
No personnel injury took place.
Notification was given to Statoil and MDN offshore and onshore management.

Picked up off bottom from 215 m to to 213 m and held TIme Out For Safety (TOFS) meeting.

Meanwhile: Baker discussed MWD operational problems with onshore support and reported the MWD tool failure mode to be a "De-Sync" failure that would not be possible to solve with the MWD tools in hole.
Prepared to inspect drilling equipment in derrick prior to POOH 26" BHA to change out MWD tools.

comments: Seal ring between top of OnTrack and modular stabilizer observed to be out of position. 
Directional Driller advised that this could be caused by a leaking and/or exploded lithium battery within the OnTrak tool, with risk of personal being exposure to toxic gas and liquids. 
All personnel were immediately moved off the drill floor to a safe area in the dog house. 
Barriered off rig floor.
Evaluated situation Baker discussed with onshore HSE organisation. Informed offshore and onshore management.
