Common Structural Rule (CSR) tankers… Do they crack? Already ?
CSR was implemented 1st of April 2006
Design standard improved with CSR Rules (25 years in the North Atlantic)
The first CSR tankers are now 8 years old – so the experience data is limited
Still cracks are found…
Why?– Production related cracks
– Cracks in details not covered by CSR Rules
