Deepsea Nordkapp


What happened in Surface section:
Unable to locate XO sub (DC58/TT550 NOV/Intelserv) offshore for 17 ½” BHA. New crossover had to be mobilized ASAP.

What Was Planned

M/U 17 1/2″ BHA to WDP .

What Was Learned

Had meeting with Halliburton and NOV coordinators discussing how to avoid missing equipment. Went through the BHAs line by line to ensure no string component was forgotten.

The current setup on Nordkapp with three providers for the BHAs (Halliburton, NOV and OWS) and two DP thread systems (5 ½” FH and TT550) is far from ideal and the risk of missing equipment / sending out wrong equipment is high.

What Actions Are Required

Halliburton coordinator to take ownership of whole BHA string, including NOV and OWS items. OWS coordinator was informed about the plan.

Evaluate the need for WDP as it complicates operations significantly without significant benefits with regards to operational time.
