ClassNK Makes Breakthrough Finding For Ultra-Large Container Ships

ClassNK has concluded that the minimum required brittle crack arrest toughness for extremely thick brittle crack arrest steel plates of 100mm used in ultra-large container ships is 8,000 N/mm3/2. The technical expertise is a world-first and is based on verification tests carried out as part of a joint R&D project in collaboration with Japan Welding Engineering Society (JWES).
