Rotor stand

Design and verification of a full rotor stand for offshore operations including adapters fitting different rotors.

The task included:

  • Design risk assessment and instructional handbook in accordance with harmonized standards.
  • 2D drawings and instructions for full rotor sea transport, full rotor MCE storage, equipment transport, equipment storage, and handling of equipment.
  • Load determination taking into account critical blade wind loads during MCE storage and survival conditions, and large rotor moment of inertia during sea transport.
  • Detailed finite element analysis in ANSYS of rotor stand and adapters, including bolted connections, welded connections, twist-lock connections and deck fastening.
  • Evaluation of fatigue life and allowable sea transport conditions for full rotor sea transport.
  • Reporting including utilization of all load carrying members.
  • Test and approval of design, user manual and instructions through FAT and SAT.
