01What is being requested

This market consultation concerns the relining of grey cast iron gas pipelines as a trenchless renovation technique. The goal is to collect market insights for a future contract with an indicative total contract value of several tens of millions of euros over a multi-year period, where an indicative annual volume of several kilometers is expected.

RFI: Through this market consultation, Alliander explicitly seeks to assess to what extent market parties are able to meet the required safety, quality and organizational conditions for relining of gas pipelines. Background Within the Dutch gas distribution network, a substantial number of pipelines are made of grey cast iron. Due to ageing-related integrity risks and regulatory requirements, these pipelines must be remediated. Traditionally, this remediation is performed by open trench replacement. In densely populated areas, open trench replacement often results in significant societal disr

11Frequently asked questions

What is the purpose of this market consultation?
The purpose is to assess to what extent market parties can meet the required safety, quality, and organizational conditions for the relining of gas pipelines.
Why has the relining technique been chosen instead of traditional methods?
Relining is a 'trenchless' alternative to traditional replacement via open trenches. This is applied to limit societal disruption in urban areas, shorten execution time, and manage interaction with other underground infrastructure.
What requirements must parties meet regarding suitability?
Parties must have a demonstrable capacity to meet the specific requirements set for the renovation of gas distribution networks.
What is the technical result of the relining method?
By installing a liner in the existing gas pipeline, a new, gas-tight pipeline is created within the original pipe after installation and curing. This restores structural integrity and extends the technical lifetime of the asset.
