LIFTING ANALYSIS
Lifting Analysis
Structural and mechanical analysis for offshore and onshore lifting operations including rigging analysis, DAF determination, lift point assessment, and load path verification.
Smart Veritas provides structural and mechanical analysis for offshore and onshore lifting operations. Our engineers verify that rigging arrangements, lift points, and structural interfaces can sustain the loads imposed during lifting, including dynamic and skew load effects.
Rigging Analysis
We analyse rigging configurations including sling loads, shackle capacities, spreader beam design, and equalisation of multi-point lifts. Our calculations verify that all rigging components are adequately sized for the applied loads, accounting for weight uncertainty, centre of gravity tolerances, and dynamic amplification.
Dynamic Amplification Factors
We determine dynamic amplification factors (DAFs) for offshore lifts from time-domain motion analysis, accounting for vessel motions, crane tip response, and load dynamics. DAFs are derived for specific lift configurations and environmental conditions rather than relying on generic code values, giving confidence that design loads are representative.
Payload Excursion & Resonance Analysis
We analyse payload behaviour during offshore lifts, quantifying horizontal and vertical excursions at the hook, at the payload centre of mass, and at any other points of interest throughout each phase of the lift sequence. Our analysis identifies resonance conditions where the natural period of the crane-wire-payload system aligns with the vessel motion period, and we assess the resulting amplification effects on load swing and dynamic forces.
Lift Point Assessment
Through our partners at Lanza Engineers, we assess lift point designs including padeye geometry, weld sizing, cheek plate details, and local structural capacity using finite element analysis. Our assessments verify that lift points can sustain the factored loads imposed during lifting, including out-of-plane and skew load effects.
