Norway
Ship-to-Shore Container Crane
1976
Condition & Residual Life Assessment
PROJECT OVERVIEW
The Challenges
The goal of this project was to determine the possibility and conditions for further operation of a ship-to-shore container crane manufactured in 1976, based on the condition of the metal structure and actual operating conditions.
The assessment included inspection of the boom steel structure, structural analysis for different trolley positions, stress measurements at critical points of the boom structure, and residual life assessment.
CRANE ASSESSMENT
Inspection & Structural Evaluation
Using coercive force method.
For the crane boom for different trolley positions.
For critical points of the boom structure.
Based on material degradation and actual loading conditions.
STRUCTURAL ANALYSIS
Crane Boom Verification
FIELD MEASUREMENTS
Stress Measurements
> Stress alteration measurements at critical points of the boom
> Critical structural area evaluated as part of the boom assessment
PROJECT OUTCOME
Engineering Assessment Result
The engineering assessment combined inspection of the boom steel structure, structural analysis for different trolley positions, stress measurements at critical points and residual life assessment. The evaluation was based on the condition of the crane structure, material properties and actual loading conditions to determine the possibility and conditions for its further operation
