comments: Changed around stabilizing liners on TDS due to observed wear on drillpipe couplings. Observed rear liner crest more worn than front liner crest. Discussed options. Carried out rig repair of worn liner, i.e. clad welding. Installed modified liner crests on TDS. Comment : New stabilizer liners ordered from rig 30/1-09. Order sendt from Maersk office in town to supplier 8/4-09.
