Construction of INEOS’s Project ONE has progressed significantly over the summer months, with the completion of a major milestone in the ethane tank roof construction. The project team has successfully applied 4,000 cubic metres of concrete to cover the roof of the Project ONE ethane tank, representing a critical phase in the facility’s development.

Complex Construction Process

Due to the tank’s substantial size, the concrete roof construction required a two-phase approach utilising equal layers. The first layer installation involved pressurising the tank from the inside to provide structural support for the wet concrete until it achieved sufficient strength to become self-supporting.

The second concrete layer was applied in nine separate sections, a methodical approach designed to ensure optimal surface finish quality across the entire roof structure. This careful sectioning process demonstrates the technical precision required for large-scale industrial construction projects.

Upcoming Construction Phases

The completion of the concrete roof sets the stage for the next phase of construction activities. Project teams will proceed with the installation of top structures, including steel framework, piping systems, and electrical infrastructure. These components represent critical elements in the facility’s operational capability and safety systems.

Investment in Sustainable Technology

INEOS is investing €4 billion in developing what the company characterises as Europe’s most sustainable cracker facility at the Port of Antwerp. The project incorporates the best available technology with the objective of establishing new environmental performance standards from the facility’s operational launch.

The investment represents a significant commitment to advancing sustainable petrochemical production in Europe while maintaining competitive industrial capacity. The facility’s design emphasises environmental performance through advanced technology implementation and operational efficiency measures.

Strategic Significance

Project ONE represents a major industrial development within the Port of Antwerp, positioning the facility to serve European petrochemical markets with enhanced sustainability credentials. The project’s scale and technological approach reflect INEOS’s commitment to balancing industrial growth with environmental responsibility in the evolving energy and chemicals sector.
