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 (goalseek) available to optimize rigging lengths 
Tilt calculations 
All tilts are calculated and reported 
Rigging geometry 
Complete rigging geometry is accurately calculated using buildin a nonlinear FEM solver. 
Stiffness of lifted object 
Can be included if known 
Spreaderbars 
Can be fully included. Bending moments, torsion and compression are reported. 
Liftpoints 
Governing loads and angles are calculated reported 
Bending losses 
Decrease of allowed load due to bending losses is automatically calculated 
Sling 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.
