What happened in Top hole:
ROV was only equipped with standard jetting tool with low flowrate, unable to remove larger amounts of cuttings from PGB

What Was Planned

Clean PGB with the ROV to save time

What Was Learned

ROV did not have capability to clean cuttings of the PBB

What Actions Are Required

Rent dredging equipment (suction pump) that can be installed on ROV for future projects with cuttings return to seabed.

What Was Done

Used drill bit to clean PGB and area outside PGB. Pumped SW at hi-rate, 4500 lpm. Moved rig on anchor chains to position hanging BHA around the PGB, a time consuming and resource demanding process. Occupied deck crew on winches.
