Belzona Facts:

Attempted weld repairs had only caused further damage and replacements would take 6 months to deliver at a cost of £40,000. More importantly if another fire pump became inoperative the rig would be shut down at £100,000 per day losses. The Belzona application cost £1,400 and all the spiders were available for re-assembly in less than 1 week.
