Intact and Damage Stability
  • Intact and damage stability calculation for all types of vessel, with an emphasis on passenger and Ro-Ro passenger ships.
  • Newbuilding concept and conversion feasibility studies assessed in respect of stability issues.
  • Preparation of stability documentation and guidance in conjunction with senior officer training and the conduct of workshops / lectures on stability issues.
  • Attendance at model testing for Stockholm Agreement compliance and the preparation of supporting calculations.
