Multi-million euro contract for construction and maintenance of Botlek West Steam Pipe

Visser & Smit Hanab, a VolkerWessels company, recently signed a contract for the construction and maintenance of the Botlek West Steam Pipe in Rotterdam. The value of the contract is approximately € 12 million. This project is a development of grid operator Stedin, Port of Rotterdam Authority and Visser & Smit Hanab.
The network will transport steam from one factory to surrounding factories that require steam as a production resource. These factories currently produce steam using expensive fossil fuel. The first part of the network will be laid in the West section of the industrial area, but the goal is to extend the network in the Botlek area in the near future. Factories along the network can supply or consume steam as required. The entire steam network will decrease the annual emission of CO2 with more than 200,000 tonnes. The project significantly contributes to the Rotterdam Climate Initiative.

The Steam Pipe

The pipeline runs from waste processing facility and steam producer AVR to chemical facility and steam consumer Emerald Kalama Chemical (EKC), covering a distance of 1.5 kilometres.


The entire network consists of two pipelines. The primary steam pipeline has a diameter of DN500 and operates at a pressure of 40 bar and temperatures of up to 420 degrees Celsius. The condensate return pipeline has a diameter of DN200 and operates at a pressure of 25 bar and temperatures of up to 183 degrees Celsius.


During the first phase, the Steam Pipe has a capacity of 88 tonnes of steam per hour. The network design allows for an increase of capacity, should more customers purchase steam.


Visser & Smit Hanab is not only responsible for the construction of the pipeline but also for the design and engineering, as well as the project management during the execution phase. In addition, the contract includes maintenance for the next 15 years. Visser & Smit Hanab subsidiary Pipeline Control will take care of the maintenance.


The development of the Botlek West Steam Pipe is another step towards our goal to achieve a more sustainable society together with our clients.
