Description MOORINGPREPAR section

The reference manual can be found here.

This section is compulsory when in the General-section "MooringPrepar" has been chosen at the Application-key.

Note that the mooring preparation functionalities can only be used for a single body with one mooring system.

[MOORINGPREPAR]

Keyword Unit Description Options Version
AnalysisType [-] Selection of mooring analysis type, must be one of the following:
- DynFloatOutput
- SingleLinePrepar
- AllocateAnchors
- SystemStaticLoad.
When DynFloatOutput is selected one or more of the following keys can be used:
- CalcEqui
- CalcEnvirEqui
- CalcPosSequence
- CalcForceSequence
Compulsory aNySim_v10.3
BodyIndex [-] Index of body for which the analysis has to be done. Compulsory aNySim_v10.3
CalcEqui [-] DynFloatOutput option: flag for calculating the body's equilibrium position without environment, either true or false. Optional aNySim_v10.3
CalcEnvirEqui [-] DynFloatOutput option: flag for calculating the body's equilibrium position including environment, either true or false. Optional aNySim_v10.3
CalcPosSequence [-] DynFloatOutput option: flag for calculating the mooring forces for a series of body offsets, either true or false. Optional aNySim_v10.3
CalcForceSequence [-] DynFloatOutput option: flag for calculating the body's equilibrium positions for a series of forces acting on the body, either true or false. Optional aNySim_v10.3
Noffset [-] For CalcPosSequence and SystemStaticLoad: the number of body offsets. Compulsory if
CalcPosSequence = true
aNySim_v10.3
SurgeOffset [m] For CalcPosSequence and SystemStaticLoad: array with length Noffset containing surge offsets. Optional aNySim_v10.3
SwayOffset [m] For CalcPosSequence and SystemStaticLoad: array with length Noffset containing sway offsets. Optional aNySim_v10.3
HeaveOffset [m] For CalcPosSequence and SystemStaticLoad: array with length Noffset containing heave offsets. Optional aNySim_v10.3
RollOffset [deg] For CalcPosSequence and SystemStaticLoad: array with length Noffset containing roll offsets. Optional aNySim_v10.3
PitchOffset [deg] For CalcPosSequence and SystemStaticLoad: array with length Noffset containing pitch offsets. Optional aNySim_v10.3
YawOffset [deg] For CalcPosSequence and SystemStaticLoad: array with length Noffset containing yaw offsets. Optional aNySim_v10.3
Nforceseq [-] For CalcForceSequence: the number of force combinations acting on the body. Compulsory if
CalcForceSequence = true
aNySim_v10.3
FxForce [kN] For CalcForceSequence: array with length Nforceseq containing surge forces. Optional aNySim_v10.3
FyForce [kN] For CalcForceSequence: array with length Nforceseq containing sway forces. Optional aNySim_v10.3
MzForce [kNm] For CalcForceSequence: array with length Nforceseq containing yaw moments. Optional aNySim_v10.3
OutputProperty [-] For SingleLinePrepar: must be one of the following:
- TensionAtFairlead
- TensionAtAnchor
- AngleAtFairlead
- LineLengthOnSeabottom.
Note: this item is required by the DynFloat GUI (interactive functionality). In the standalone aNySim all these properties are reported, so in that case the choice is arbitrary.
Compulsory if
AnalysisType = SingleLinePrepar
aNySim_v10.3
RestoringOutput [-] For SystemStaticLoad: must be one of the following:
- Fx
- Fy
- Fz
- Mx
- My
- Mz.
Note: this item is required by the DynFloat GUI (interactive functionality). In the standalone aNySim all these properties are reported, so in that case the choice is arbitrary.
Compulsory if
AnalysisType = SystemStaticLoad
aNySim_v10.3
InFloaterSoc [-] For SystemStaticLoad: flag which indicates whether the mooring forces are reported in the local body system of coordinates (InFloaterSoc = true) or in the earth-fixed system of coordinates (InFloaterSoc = false).
Note: this item is required by the DynFloat GUI (interactive functionality). In the standalone aNySim the forces are reported in both systems of coordinates, so in that case the choice is arbitrary.
Compulsory if
AnalysisType = SystemStaticLoad
aNySim_v10.3
