Dubai-based Al Faris Group, known for its state-of-the-art lifting, a range of transport equipment and expertise in complex planning and execution, was recently awarded a project to instal a steam box at the Al Warsan Waste-to-Energy Plant.
The challenging installation was done at a height of 2.8m using Al Faris’ specialised in-house modular towers and other skidding equipment.
The steam box was delivered in two parts, the bottom part weighing 27t and the top part weighing 40t.
The top part was tandem lifted for top and tail operation using its 250t and 200t mobile cranes. It was then placed onto skid tracks and skidded into a temporary position. Thereafter the bottom part was placed on the skid tracks. The top part was then lifted to allow the bottom to be skidded underneath.
Once the bottom part was skidded into final position, the top part was lowered onto the bottom part and both parts of the steam box were joined together for final installation.
The clearance while skidding was only 30mm. All measurements and markings were done precisely during the operation.
The COG of the top part of the steam box was away from both the lifting points during the lifting of the load from the trailer which could have caused the load to slide. To avoid this situation, Al Faris made a temporary packing arrangement of stools at the corner of the steam box.
A project of this nature requires exceptionally detailed planning to orchestrate the complex activities necessary for ensuring uninterrupted safe services; from detailed planning to ensuring utmost safety during all lifts.
The technical support documentation, execution plans and HSE protocols were prepared in-house and discussed with the client prior to project execution.
