“ARE” COWI was appointed to investigate the existing billet bay crane gantry, during the unscheduled shutdown period. The elements inspected were columns, beams supporting crane rails, rail and exposed foundation.
The work involved visual inspection, dynamic assessment of the beams supporting the rails, die penetration testing of certain welds and static alignment survey. Calculations were also carried out to assess the adequacy of the structure according to the DIN standards. Following the investigation we prepared a report giving recommendations on how to prolong the life of the structure.
