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.
