  • Performance and the ultimate capacity of suction caissons under combined loading
  • Performance of drag embedment anchors in sand and clay
  • Skirt foundations under combined loading
  • Riser-seabed interaction and its impact on fatigue performance of catenary risers
  • Deep penetrating and drag-in plate anchors
  • Large deformation finite element analysis (LDFE) of offshore foundations
  • Subsea landslides and slope stabilities
  • Performance of spud cans and jack-up foundations under combined loading
  • Pipeline stability under hydrodynamic loading
  • Deep water installation techniques of subsea manifolds
  • Pile foundations
