Float-over Analysis

Float-over Analysis

A full dynamic mooring analysis tool has been developed which will perform a standardised dynamic mooring analysis includind a code check. The tool will determine the first and second order dynamic response of the vessel using 3-D diffraction on a 3D representation of the vessel hull. The calculated vessel responses include the stiffness effects of the mooring lines. To improve the efficiency of the analysis it has been chosen to performe the analysis in the frequency domain.

The output of the model is a ready for issue report describing the used input, the models used and the results and conclusions of the analysis. The model runs on the Online Marine Engineerig server and uses the state of the art marine simulation software MOSES from Bentley.

Mooring Model Specification:

  • Multibody aanalysis capability
  • 3D Hydrodynamic analysis of mooring spread 1st and 2nd order motions
  • Check for two environmental conditions and two tidal current conditions
  • Database of steel wire, chains and synthetic lines
  • Check of pipeline crossings
  • Offshore spread mooring and/or berth moorings
  • Damaged line check including time domain transient mooring analysis
  • Results presented as capacity rosettes as function of environmental heading
  • Compliant with API, DNV Posmoor, GL-Noble Denton, IMO guideline
  • Approved and used for various offshore projects
