Statoil Gina Krog Jacket

Orca Offshore has been responsible for the Naval Architectural design of the Statoil Gina Krog (previously Dagny) jacket. The work has been performed as part of the Heerema Fabrication Group design team and included;

  • Transport motion analysis
  • Jacket launch Design and analysis
  • Upend Design and analysis
  • Concept design of jacket ballast system

ORCA Offshore was involved in this project from FEED to detailed design. Simulations of the transport, launch and upending have been performed using MOSES from Bentley.

Major challange of this unique jacket design was to assure that during all phases of construction, transport and installation the loads would be within the limits of the jacket, the launch barge and the crane vessel.
