NOV and CoreMarine collaborate on crane digitalisation

CoreMarine and National Oilwell Varco (NOV) collaborated to develop and validate a new precision tool, the NOV Crane Simulation Module (CSM). With the CSM, it is now possible to simulate real offshore behaviour and crane modes such as Active Constant Tension or Active Heave Compensation all within Orcaflex.

‘We see huge benefits in being able to accurately model the complex lifts associated with floating wind installations and complex offshore lifts in general.’ - Øyvind Johnsen, Technical Director, CoreMarine.

CoreMarine has performed the validation of the tool in OrcaFlex and proved that it is a valid representation of the real crane for its different modes. This opens new horizons for offshore construction. We foresee large reductions in engineering assumptions leading to vessel day optimisation, improved lift performance and confidence for ultra-complex lifts. The tool is not only suitable for execution engineering but for quick-fire tendering analysis that requires a higher level of certainty.

CoreMarine and NOV are now aiming for Approval in Principle (AIP) through DNV GL for the CSM.

This tool can be used directly with hydrodynamic analysis software such as Orcaflex. CSM enables real crane behaviour simulation and modes like Active Constant Tension, Active Heave Compensation or Splash Zone Mode. The CSM accurately represents the hydromechanical parts of the crane and of the control system making it the most advanced crane module available for analysis.
