comments: Held pre-job meeting prior to perfoming wiper trip. RIH from 152 m to TD at 208 m, observed string jump when first starting to RIH. 
Observed mark on DP at rotary table indicating 36" BHA on bottom, set down 2-3 ton to tag same. Depth tag at bottom indicated no fill. Pumped 50 m3 1.40 sg mud to displace hole, 3200 lpm, 22 bar. 5 rpm. 

Meanwhile: monitoring weather conditions.

comments: Started POOH 36" BHA from TD at 208 m. ROV moved towards F-11 well centre to observe POOH and observe 36" hole opener assy had detached from string. ROV checked template and observed 36" hole opener fish sticking up out of F-11 well slot with top of fish approximately flush with top of F-11 guide funnel (Top of Fish (TOF) at ca. 140,20 mRKB).

comments: Evaluated risk of POOH recoverable section of BHA up through Volve Platform. 
Held pre-job meeting. POOH and found that BHA had parted at a service break connection on the jar body. From recovered section of BHA estimated fish length to be 58,52 m, approximately 14 ton (in air).
Evaluated situation and discussed same with town.

Meanwhile: ROV pulled back to safe area 50 m from F-11 well centre while POOH BHA.

comments: Discussed situation with town. Mobilized fishermen and fishing equipment.
ROV attempted to observe TOF in guide funnel, poor visibility in template area.

Meanwhile: ROV surveyed of risers, no damage observed. Survised drilling equipment and took onboard bulk from supply vessel.
