[QUOTE=alvis;40053]I think it was the Forma-set (sp?). He said it needed a liquid component before it would harden. There was some talk yesterday that after the first explosion, they found what they described as “snot” on the rig deck. And that it might have been this LCM.[/QUOTE]
I’m sure it was snot or LCM.
bp have already stated that the rig underdisplaced the (snot and) seawater prior to the integrity tests.
Quite likely they also underdisplaced ?again? thereafter when clearing out the riser to seawater.
When they eventually shut down for the sheen test all the above factors would mean that there was still LCM in the riser.
