Rigging

The Rigging module adds features to enable design, analysis and reporting of rigging systems using DNVGL ST N001 method or IMCA methods.

Design, analysis, 3d visualization and reporting from the same model.

Feature
Skew load calculation	Automatic application via rigging item length variations, alternatively a factor can be provided
Dual crane lifts	Automatic application determination of 1m / 3 degrees criteria. Configurable.
CoG envelope	CoG envelope can be incorporated.
Rigging stiffness	Stiffness of steel rigging items can be estimated if not known
Hook geometry	Geometry of the hook(s) is fully included in the analysis
Friction	Friction effects (first and higher order) can be fully included
Rigging length calculations	Solvers (goal-seek) available to optimize rigging lengths
Tilt calculations	All tilts are calculated and reported
Rigging geometry	Complete rigging geometry is accurately calculated using build-in a non-linear FEM solver.
Stiffness of lifted object	Can be included if known
Spreaderbars Spreaderbeams	Can be fully included. Bending moments, torsion and compression are reported.
Liftpoints Padeyes Trunnions	Governing loads and angles are calculated reported
Bending losses	Decrease of allowed load due to bending losses is automatically calculated
Sling geometry Grommet geometry	Geometry of rigging items over round surfaces such as shackles, trunnions and grommet protectors is fully included.
Drawings	3D visuals are produced and can be exported to Blender (and from there to 3D CAD)
Shackles	Typical shackle models (GP, GN) included, more can be added
Company assets	Cranes, Spreaderbars, Spreaderbeams and Hoists can be
Reporting	Complete calculation reports produced as pdf.
