IN Brief:
- WarmtelinQ has started construction of a heat transfer station and buffer installation at Vondelingenplaat.
- Dura Vermeer is delivering the civil and building works, with Equans responsible for the technical installations.
- Heat exchangers, pumps, and a dynamic pressure-maintenance system will regulate heat transfer and prevent steam formation within the network.
WarmtelinQ has started construction of a heat transfer station and associated buffer installation at Vondelingenplaat in Rotterdam, with the first specially designed foundation pile marking the beginning of the plant package.
Dura Vermeer and Equans are delivering the facilities. Dura Vermeer is responsible for the civil and building works, while Equans will install the technical systems needed to transfer residual industrial heat through WarmtelinQ’s regional network.
The heat transfer station will contain heat exchangers and pumps that allow heat carried by the main transport system to be transferred into connected local networks. Alongside it, the buffer installation will act as a dynamic pressure-maintenance system for the route towards The Hague and Leiden.
Pressure control is critical because the network operates with high-temperature water. WarmtelinQ says the water can reach approximately 120°C during winter, requiring the system to remain sufficiently pressurised to prevent steam formation and maintain reliable circulation.
Dozens of specially designed foundation piles will support the installation, with extensive quality controls planned during construction. The first pile therefore marks the start of the foundations beneath equipment that will perform both thermal-transfer and hydraulic-control functions once the network is operational.
The facilities sit at Vondelingenplaat within the Port of Rotterdam industrial area, where WarmtelinQ begins carrying residual heat towards Vlaardingen, Delft, Rijswijk, The Hague, and Leiden. The site is one of the interfaces required to turn a long-distance pipeline into an operable regional heating system.
That distinction is important because WarmtelinQ provides the main heat transport infrastructure rather than every local network connected to individual buildings. Transfer stations are needed where heat crosses between systems, allowing temperatures, flows, and operating conditions to be managed at defined points.
John Brussel, General Director West Netherlands at Equans, said the company would use experience gained from district-heating projects to help move heat to the places where it is required. Henk-Jan Slager, Director at Dura Vermeer, described Vondelingenplaat as a complex industrial environment where close cooperation between client and delivery partners is necessary.
The industrial setting shapes the construction programme. New foundations, buildings, mechanical equipment, pipework, electrical systems, and controls have to be installed among existing port infrastructure, where access, logistics, lifting activity, and interfaces with operating assets are more constrained than on an isolated site.
Dura Vermeer’s structural work therefore establishes the geometry and support conditions for the technical package that follows. Equipment positions, pipe entries, loads, access, and maintenance clearances all need to align before Equans can complete the mechanical and electrical installation.
The buffer system adds an operating requirement that is less visible than the heat exchangers but equally important. Moving water at around 120°C over a regional network requires hydraulic conditions to remain within controlled limits; without sufficient pressure, local boiling and steam formation could undermine both reliability and safety.
WarmtelinQ Director Inge Aardse described the Vondelingenplaat installation as an essential link in making Rotterdam port residual heat available on a large scale. WarmtelinQ says its wider network is intended to transport heat for approximately 120,000 households and businesses across South Holland.
That figure describes the eventual scale of the transport system rather than the number of customers immediately connected when Vondelingenplaat is completed. Local distribution networks and receiving infrastructure still have to be available before heat can move from the regional backbone into individual buildings.
The project is already being delivered as a sequence of route sections and plant packages at different stages. Buried pipe can be installed, tested, and reinstated comparatively independently, while a transfer station has to progress through foundations, building work, mechanical and electrical installation, controls, connections, testing, and commissioning.
That difference explains why plant interfaces frequently remain active after long stretches of linear infrastructure appear physically complete. A pipeline provides the transport route, but pumps, valves, exchangers, pressure systems, and controls determine whether heat can actually move through it under stable operating conditions.
The start at Vondelingenplaat therefore shifts part of WarmtelinQ’s construction programme from installing transport infrastructure to building the equipment required to operate it. The foundation works now under way will ultimately support a station where civil engineering, mechanical plant, electrical systems, and control logic have to function as a single asset.
District-heating projects can look straightforward on route maps: one heat source connected to a series of destinations. The difficult engineering tends to accumulate at the interfaces. Vondelingenplaat is one of those points, where high-temperature water has to be transferred, pumped, and kept under pressure before kilometres of buried pipe can perform the job for which they were installed.
