The Netherlands is working towards a sustainable future with reduced CO2 emissions and less natural gas. Therefore, Gasunie is constructing WarmtelinQ: the heat pipeline through South Holland. The WarmtelinQ construction is divided into five route sections (lots), with Lot A, Lot B, and Lot D awarded to A.Hak. The production, distribution, and supply of heat are handled by other parties.
WarmtelinQ Project
The construction of this heat pipeline, utilizing residual heat from the Rotterdam port area, is a crucial link in the regional energy strategy for South Holland. It is an excellent project that the Dutch government uses as a showcase in negotiations concerning the energy transition.

Reduced CO2 Emissions
Heat projects lead to reduced CO2 emissions and less natural gas consumption. This project involves an underground pipeline from Vlaardingen to The Hague. The heat pipeline, using residual heat, can heat 120,000 homes and businesses in South Holland. From WarmtelinQ, other, smaller future heat distribution networks can be supplied. These then deliver the heat to homes and businesses.
Project Scope
The project concerns the construction of heat pipelines for the heat network from Vlaardingen to Delft and a section in Rijswijk and The Hague. The pipeline is large, and we are constructing it through varied terrain, encompassing both urban and rural areas. Stakeholder management is a crucial part of the assignment; without public support, the project’s execution cannot be guaranteed.
All aspects of our in-house expertise are utilized, such as welding, insulating, and drilling. On Lot A, Lot B, and Lot D, we are performing a double HD drilling of approximately 1,000m, 4 double closed-front drillings, and 4 arc drillings.
