Basic Jacking & Rigmove

To give an understanding of safe rig move and jacking operations for jackups in theory and practice. Practical exercises will be completed in an advanced motion platform jacking simulator.


  • Planning of rigmoves, using relevant procedures and legislation
  • Seabed / Soil Properties.
    • Seabed friction on legs.
    • Stuck leg(s).
  • Preloading:
    • Site specific
    • Geo/Soil
  • Maneuvering theory
  • Person in Command (PIC)
  • Basic Stability for jack-up
  • Jacking systems
  • Jetting system
  • Raw water legs
  • Rack Phase Difference (RPD):
    • RPD Program
    • Eliminate RPD
  • Rapid penetration / Punch-through.
  • Torque on legs.
  • Max inclination of rig versus distance to platform.
  • Crane operations during transit.
  • Heavy lift operation
  • Tow / Anchor-handling vessel operations
  • Risk assessment.

To be able to:

  • Move on to final location by anchors & start jacking
  • Open location using 2 vessels.
  • Pre-load and punch through
  • Freeing legs
  • RPD Issues
  • Ship handling and rig moves in simulator.
  • Communication / Teamwork between rig and A/H Vessels.
  • Risk assessment.
  • Emergency Response Scenario
