What happened in Top hole:
Due to problems with cement around the conductor and movement in conductor a Bullseye bracket from DQ was sent out but not installed.

What Was Planned

No inclinometer was planned. Only planned for measuring the inclination of the WH with the bullseye on the WHRT.

What Was Learned

The bullseye bracket not suitable to install subsea.

What Actions Are Required

If WH already installed without an installed tool for measuring inclination, evaluate to use a three-leg WH inclinometer from Oceaneering that can be installed subsea.
