40-Year inspection of quay crane
Scope of the inspection:
The crane boom has been fully inspected using Eddy Current Testing (EC) on all accessible welds.
The crane tower has been partially inspected, with a focus on weld joints in critical load-bearing areas.
Eddy Current Testing was applied to a large number of weld joints, selected based on previous load history and structural vulnerability.
Purpose of the inspection:
To document the structural integrity of the crane
To detect any defects in critical areas
To provide a basis for further service life assessment and maintenance strategy
In connection with a 40-year inspection of a 105-ton quay crane, Synfaring AS has carried out a comprehensive non-destructive inspection (NDT), with a primary focus on Eddy Current Testing (EC).
The inspection work forms a central part of the crane's condition assessment after several decades of operation and is intended to ensure continued safe use.
The Eddy Current method is particularly well-suited for detecting surface-near cracks and discontinuities in conductive materials and allows for high-resolution inspection without the need to remove surface coatings. This enables efficient progress with minimal impact on the structure.
Synfaring AS has delivered all results and recommendations as part of a complete inspection report, which will be included in further technical assessments by the crane owner and maintenance personnel.
The work illustrates how modern NDT methodology can contribute to cost-effective and accurate maintenance of aging lifting equipment.
