No. 152. Crevoprene

High build neoprene coatings have been a staple in the offshore industry for years – usually as a splash zone coating.  There have been reports of lack of adhesion at the ends of the joints (see top plate).  This can be particularly problematic if said end is in the splash zone – here I was fortunate enough to witness a riser failure in real time (it’s what we offshore corrosioneers live for).  I trust that the manufacturers have since solved this nagging design flaw.
