Improving vessel design with hull stress and fatigue data

Improving vessel design with hull stress and fatigue data

Hull stress monitoring has been a feature of commercial shipping since the 1990s, but according to Terje Sannerud from marine structural monitoring specialist Light Structures, it is today finding applications for improving ship design, insightful maintenance and potentially extending the period between dry-dockings allowing for cost savings without compromising ship safety. Ships can become damaged, […]
