Vegard Longva
About
My working duties at the Department of Marine Technology is teaching in the course Marine Technology 2 - Structures (TMR4167). I am also employed as a Senior Research Scientist at SINTEF Ocean at the Structural Engineering Group.
Field of interests:
- Development of numerical methods for non-linear global structural analysis:
- Contact formulations
- Beam formulations
- Lagrangian-Eulerian formulations
- Global response of slender marine structures:
- Interaction between fishing gear and pipelines and other subsea structures
- On-bottom-stability of pipelines and cables
- Torsion response in handling operations for cables and flexible pipes
- Development of commercial software for slender marine structures
- Teaching
