Sarens Assist Visser & Smit Hanab on Evides Pipeline Project

In anticipation of increasing demand for raw water in the future, Evides Waterbedrijf called on Visser & Smit Hanab to upgrade and extend segments of the current raw water conveyance network, stretching from the reservoirs in the Dutch Biesbosch region to Zeeland.

Situated in Roosendaal, North Brabant, a 750m long pipeline had to be drilled. The pipeline’s path passed under a railway track, necessitating meticulous planning and flawless execution to ensure success.

Sarens was tasked by their client Visser & Smit Hanab to assist in the drilling of a 750m pipe beneath the railway track using a 450t drilling rig.

Sarens crew had to address the challenges while lifting the pipeline namely:

  • the considerable length of the pipe,
  • the substantial diameter of 1.40m,
  • limited space available onsite.

Understanding the challenges and site conditions, Sarens deployed twelve mobile cranes with capacities ranging from 130t to 300t. A narrow road and limited space on-site meant that the cranes had to adhere strictly to a predetermined hoist plan, with each crane carefully scheduled to avoid congestion and maximise efficiency.

The retraction arc was meticulously calculated, and the positioning of the mobile cranes was strategically determined to optimise operational 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 36t per crane, including the weight of the cradles. Despite the heavy weight and size of the pipeline, the cranes performed the lifting operation safely, ensuring that the pipe was lifted and retracted with utmost care and precision.

According to Sarens Supervisor, Michael Brama, “The project showcased the epitome of meticulous planning, strategic coordination, and unparalleled execution by our crew. We are extremely proud of our team”.
