Completing the project for Visser & Smit Hanab, the 750m-long pipeline was requested by Evides Water Company to cope with an anticipated increased demand for raw water in the future. The pipeline faced several difficulties during installation: first was its mammoth length, second the diameter of 1.4m and, lastly, the pipeline’s installation path was to traverse beneath a railway track, requiring extensive planning and execution to ensure success.
“The project showcased the epitome of meticulous planning, strategic coordination, and unparalleled execution by our crew,” said Sarens Supervisor, Michael Brama. “We are extremely proud of our team.”
To complete its scope of work, Sarens’ 12 mobile cranes ranged from 130 tonnes through to 300 tonnes. A narrow road and limited space on-site meant that the cranes had to adhere strictly to a predetermined hoist plan, with each crane’s arrival carefully scheduled to avoid congestion and maximise efficiency.
The retraction arc was extensively calculated, while the positioning of the mobile cranes was strategically determined to optimise efficiency. Additionally, the necessary facilities for the cradles were planned and executed, ensuring seamless integration into the operation.
Upon arrival at the site, the twelve mobile cranes were assembled in half a day and remained onsite for two days. Throughout the two-day duration, each crane operated at maximum capacity, with a load of approximately 36 tonnes per crane, including the weight of the cradles. Despite the heavy weight and size of the pipeline, the cranes safely performed the lifting operation, ensuring that the pipe was lifted and retracted with a high level of precision.
