Challenges

  • First time a fully erected Liebherr STS Cranes were transported via lift-on / lift-off method on a heavy lift vessel after being built in Ireland
  • STS Cranes were not designed to have integrated lifting points
  • Alternative lifting method was used via onboard state-of-the-art rigging equipment
  • A Motion Response Analysis was carried out to assess induced forces acting on the cargo
  • Based on the results, structural calculations were performed engineers created tailored seafastening and loadspreading arrangements
  • A bespoke pulling arrangement was designed by in-house engineers in order to safely execute this operation
  • During the planning stage, due to the giant shape of STS cranes, several 3D simulations were carried out to find the best manoeuvre for placement on the stowage position
  • Considering the strong tidal current and length of the berth, a suitable mooring arrangement was planned and calculated for the required station keeping of the vessel
  • Cranes were lifted from SPMTs at the loading port in Cork and directly placed onto rails at the discharge port in Hull
  • Flag State requirements had to be fulfilled for Open Hatch Sailing, Restricted Visibility and COLREG
