The project begins with the preparation of a detailed P&I diagram, which defines the facility’s structure, components and the signals needed for control and monitoring. This establishes a foundation for the entire control architecture.

Based on the P&I diagram, we then generate a complete list of components. This list contains all of the necessary parts and functions – from pumps and valves to sensors and control units – and ensures precision within everything from purchasing to construction and subsequent documentation.

From an early stage in the project, we make sure that the design and choice of components complies with the applicable requirements for CE marking. This means that the entire solution is designed from the outset in accordance with the relevant directives and standards.

In close dialogue with the customer, we review the design, the chosen components and the functional principles. This allows the customer to validate the solution, request changes, and ensure that both the technical and practical requirements are met.

The station is modelled in 3D, creating a precise visual overview of the installation. This gives the customer an opportunity to understand the construction and functioning of the facility – and to identify any needs for customisation before production begins.

At Priess, we actively use VR as a part of our design process. Together with the customer, we will go on a virtual walkthrough of the station – considering factors such as access, servicing options and the utilisation of space.

This early validation process ensures that all details are properly considered and that the solution will be able to work in practice – and this is assured before production is commenced. Working in this way reduces the need for later adjustments, saves time and boosts confidence in the process.

We put together a detailed functional description based on information from the P&I diagram, the component list and the control logic. This describes the station’s functional purpose and operation — and forms the basis for the preparation of the control description/programming and CE documentation.

Following approval of the design and component selection, we begin production at our specialised facilities in Herning. The installation is built in sections and modules as part of a parallel and efficient process that places focus on quality, precision and traceability.
All pipes, valves, electrical units and control units are installed and the solution is brought together as a single plug-and-play unit.

FAT – Factory Acceptance Test
Before delivering, we carry out a complete factory acceptance test which covers all of the following:

• A. Non-Destructive Testing (NDT) – Ensures the quality of welds and materials
• B. Pressure testing — Verifies tightness and system resilience
• C. Input/Output Testing (I/O) – Tests all communications, signal exchange and control

The factory acceptance test can be performed in collaboration with the customer, who can participate either physically or via a remote link.

Following FAT approval, the station will be packaged and delivered directly to the installation site – ready to be connected up. Our logistics and crane operations ensure the gentle and precise handling of both small and large units.

Our fitters and technicians ensure that the facility is commissioned efficiently on site. We can connect electricity and district heating pipes, perform any final adjustments, and verify the system’s functionality under real operating conditions.

Upon completion, full documentation is prepared and the handover is completed in close dialogue with the customer. We also provide instructions on operation and maintenance, and the option for further support and follow-up after commissioning.
