- A five-step approach ensures safe rigging and lifting operations.
- The guidance compares stability assessment methods like Virtual CoG, Kaps, and numerical simulations.
- Offers insights on handling disturbing factors like wind forces, crane motion, and rigging tolerance.
The Guidance on Stability of Lifts, developed by DNV’s Heavy Lift Exchange Forum, offers a systematic approach to ensuring safe and stable crane operations in maritime environments. This document bridges gaps in existing guidelines, providing operators with methods to assess and enhance lifting stability while mitigating risks to life, property, and the environment, reports DNV.
Step-by-Step Rigging Process
Operators follow a five-step process, from drafting rigging plans to finalizing operational procedures.
This ensures comprehensive preparation and safe execution.
Comparing Stability Assessment Methods
The document compares key methods like Virtual CoG for initial stability, Kaps for versatility, and simulations for phase-specific insights.
Handling Disturbing Factors
Equations and practical strategies are used to address factors like wind forces, vessel motion, and CoG shifts and maintain stability.
Friction and Inclination Angles
Understanding sliding angles and friction-dependent points is crucial for stability in complex lifting scenarios.
Industry Collaboration
Developed through a partnership of leading heavy-lift companies, the guidance reflects collective expertise.
