01What is being requested
Realization of two relief floors (approximately 3,750 m² and 2,500 m²) in the port area in Vlissingen-Oost. The assignment includes the preparation of the execution design, demolition works, the installation of approximately 600 displacement screw injected piles (length approx. 40 meters) and the installation of a concrete relief floor with a thickness of approximately 1.20 meters.
North Sea Port intends to reinforce the existing Quarleskade through the realization of relief floors directly behind the quay wall. The reason for this is the increase in scale and weight of offshore wind components, making the current ground loading insufficient for future use.

Strategic insight · AI analysis
Focus on the technical feasibility of the piling plan within the existing anchor structure and the limited working space. Ensure demonstrable expertise in displacement screw injected piles with both lost and pulled casings. Provide explicit input during the consultation regarding risk management concerning the arching effect and the execution tolerances of the anchors.
03Points of attention

10Frequently asked questions
Why is the reinforcement of the Quarleskade necessary?
The increase in scale and weight of offshore wind components ensures that the current ground loading is insufficient for future use. The relief floors must increase the bearing capacity of the underlying terrain.
Which suitability criteria are applied?
Proof of sufficient experience on comparable maritime sites is required. Additionally, relevant technical skills, infrastructure and BIM skills, and compliance with safety permits and construction requirements are required.
What is the technical scope of the works?
The works concern the realization of relief floors that are installed directly behind the existing quay wall to increase the bearing capacity of the terrain.
What is the nature of the current phase?
This is a joint exploratory phase between North Sea Port and the Breakbulk & Offshore Wind Terminal (BOW). It is not a formal procurement procedure.
