The complete platform will be lifted and transported by the Hercules III to the new location freely suspended in the crane.

The scope of work for Orca Offshore included;

  1. Feasibility study to check the motions and jacket strength during lift, transport and re-installtion of the platform.
  2. Asian Hercules III In-field Mooring Design and Analysis
  3. Platform Lift and Setdown final dynamic analysis to define the final allowable seastates for a safe operation
  4. Platform final dynamic transport analysis to determine platform dynamic loads, motions and fatigue loads
  5. Advise operational procedures

The various stages of the transport and installation of this platform has been analysed using MOSES from Bentley utilising the Orca Offshore developed analysis procedures.
