Precision operations in the port of Casablanca: Somalev dismantles two container cranes

After more than two decades of intensive and reliable work in demanding terminal operations, two Liebherr container cranes in the port of Casablanca have been disassembled in a controlled manner. Somalev used two powerful Liebherr telescopic cranes, an LTM 1400-7.1 and an LTM 1250/1, for the complex dismantling of the large-scale equipment. Both machines were selected due to their high load capacities, their flexibility and their suitability for the confined port areas. They enabled the step-by-step dismantling of large components such as boom sections, machinery house and portal elements. Somalev made a deliberate decision for telescopic cranes instead of lattice boom cranes – an approach that allowed flexible adaptation to changing load cases and limited floor space.

Technical and operational challenges

The project was characterised by numerous technical and organisational challenges. The age-related changes to the cranes required conservative load assumptions and reinforced rigging solutions. The entire work had to take place in an active terminal environment where only limited space was available for dismantling. At the same time, clearly defined exclusion zones and permanent coordination with the port authorities and terminal operations were required to ensure a safe and trouble-free process.

Flexible solutions and the highest safety standards

The dismantling operation itself was particularly complex, as it had to be carried out in the reverse order of the original assembly operation. The various load cases required different crane configurations and rigging arrangements. Synchronised lifting operations between the LTM 1400-7.1 and the LTM 1250/1 were also necessary in several project phases that required exact planning, precise communication and real-time coordination.

Somalev also set high standards in terms of safety. The company carried out project-specific risk assessments of damaged components, implemented redundant rigging systems, defined controlled access areas and permanently monitored wind and crane parameters. At the same time, the team applied a flexible execution methodology to be able to react to unexpected structural conditions. Optimised crane configurations made a contribution to reducing the required floor space to a minimum and keeping disruptions to port operations as low as possible.

Due to the proven reliability of Liebherr cranes – even after many years of intensive use – and precise project planning, the sophisticated disassembly work was successfully completed. The completion of the project emphasises the expertise of Somalev in the field of industrial decommissioning work and proves that the company can carry out complex dismantling work safely, efficiently and with a high level of professional quality.
