MOORING LINES

MAIN FEATURES

  • Selection of an unlimited number of mooring lines for each analysis
  • Description of each mooring line through mooring installations (bollard, bitt, capstan, winch, etc.) and line characteristics (rope, wire, cable, hawser, Coulomb coefficients of static and kinetic friction, diameter, elastic modulus, yield strength, ultimate strength, etc.)
  • Analysis of positive and negative solutions
  • Computation of tension ratios as a function of rope angles or turns
  • Computation of rope angles or turns as a function of tension ratios
  • Computation of stresses and strains
  • Comparison of analytical results with available field data
  • Visualisation of analytical results and field data
  • Suitable for designing and testing

OPTIONS FOR IO OPERATIONS

  • Microsoft Excel Spreadsheet Files (xlsx)

OPTIONS FOR GRAPHICS

  • Standard Image Formats (jpeg, tiff) 
  • Portable Document Format (pdf)

TEST CASES

Figure 1 explains how tension changes with the number of turns of the cable while Figure 2 conversely illustrates how the number of turns is affected by the tension in the cable.

Figure 1. Tension ratio (Y-Axis) versus number of turns (X-Axis) for different friction coefficients.

Figure 2. Number of turns (Y-Axis) versus tension ratio (X-Axis) for different friction coefficients.
