comments: Attempted to enter 26" hole washing down 600 lpm/1 bar. Inspected string with ROV and found that 36" HO and centralizer bushing was clear of F-12 DCI. Applied 1-5 rpm and entered pre-drilled 26" hole. Washed down 1000 lpm/1 bar to 149 m. Observed with ROV that centralizer bushing had not landed out in funnel.
