What happened in Rig move:
Due to AHV cost we moored prior to spudding due to vessels been on contract due to market situation

What Was Planned

Mooring prior to spud

What Was Learned

Due to shared VFD between mud pumps and anchor winches its not very efficient to skid the rig when lined up to spud the well.
Ensure sufficient personnel to handle both BOP and anchor winches simultaniously.

What Actions Are Required

We should spud on DP and work all the way to BOP running on DP. We could moor offline when deploying the BOP and save +/- 16 hours rig time which would balance out the economics of hiring the AHV’s
