Challenges

  • Limited data available in the planning stages, including no precise weight or centre of gravity (COG) information due to the age of the units
  • Cranes were not designed to be lifted, mandating a complex lifting arrangement
  • A Mooring Analysis was also carried out to find the most effective mooring arrangement for the required station-keeping of the vessel
  • A Motion Response Analysis, using Global Wave Statistics seasonal data, to assess the maximum motion induced forces acting on the cargo during the voyage
  • Based on analyses undertaken, the required amount of seafastening points were designed and placed on the strong points of the units which made the ship unloaders suitable for transport
