20:00 - 20:15: Performed TBT prior to laying out toolstring.
20:15 - 21:30: Broke lubricator. L/d BHA on deck.
21:30 - 22:30: Prepared for w/l run punch). SLB built cable head and tested toolstring. Meanwhile lined up to test plug with cement unit. Equalized tree cross. Opened HMV. Equalized DHSV with 100 bar, no indication seen. Increased pressure to 200 bar and confirmed DHSV open by volume control.
22:30 - 23:45: Prepared for w/l run punch). SLB built cable head and tested toolstring. Meanwhile bled down pressure from 200 bar to 60 bar using closed drain for low pressure test.
23:45 - 00:00: Suspended operations on drill floor and cantilever due to ice falling down. Meanwhile continued pressure bled down for low pressure test.

24-hour summary: M/u toolstring run plug). RIH, correlated and set plug at 3147 m. POOH and l/o toolstring. Prepared wireline run Suspended operations on drillfloor and cantilever due to ice falling down.
Hourly activities:
00:00 - 02:00: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile stopped bleed down to closed drain at 40 bar as gas was bled off. Commenced low pressure test of EVO plug 40 bar/5 min.
02:00 - 04:45: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile increased test pressure in steps to 200 bar. Stopped and evaluated situation due to high volume pumped. Discussed options with town regarding test pressure and bled down after pressure test to close drain preventing hydrate formation.
04:45 - 05:15: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile pressure tested EVO plug to 225 bar/10 min. Good test.
05:15 - 14:00: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile discussed final test pressure and plan for bled down via f-12 with involved parties on rig and in town. Monitored pressure on f-1 b.
14:00 - 16:30: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile held TBT for pressure bleed down. Production department prepared line up to receive bleed from f-1 b. Bled down pressure from f-1 to f-12 from 225 bar to 35 bar.
16:30 - 00:00: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile monitored WHP on f-1 b. Performed daily maintenance and housekeeping. Bled WHP from 37 bar to 30 bar, using closed drain.

24-hour summary: Wow ice lumps falling to rigfloor/cantilever due to strong wind. Meanwhile evaluated and dicussed with onshore organization situation for pressure testing/ bled off on f-1 b. Pressure tested EVO plug to 220 bar/10 min. Bled of pressure via f-12. Performed housekeeping and maintenance while wow.
