Our core structural integrity research addresses fracture and fatigue in ships and offshore structures.
Structural mechanics provides the foundation: how structures carry load, deform, buckle, and collapse under operational and extreme conditions. Structural integrity builds on that foundation to assess crack initiation and growth, fatigue damage, and fitness for continued service.
We apply these methods to ships, offshore structures, and marine energy systems. Current work includes ductile fracture and impact, ultimate strength and progressive collapse, and fatigue assessment of floating offshore wind mooring lines and dynamic power cables. Virtual sensing, digital twins, and reproducible research software connect simulation with measurements and engineering decisions.

Mission and vision
To advance fracture and fatigue assessment for safe, sustainable marine infrastructure, and to become a leading research group in marine structural mechanics and integrity.
Cracks and fatigue damage often develop where direct observation is difficult. We investigate the mechanics of damage and failure, then turn that understanding into assessment and monitoring methods that engineers can use with confidence.
