Allseas has recently been awarded a significant contract for the construction of the subsea pipeline designated for the pioneering Porthos CO2 storage project, which represents the Netherlands' first venture into such endeavors. This development follows the final investment decision (FID) made for the project, underscoring the nation's commitment to sustainability and environmental responsibility.

The scope of Allseas' involvement entails the comprehensive installation, burial, and commissioning of the 16-inch carbon capture and storage (CCS) pipeline. The pipeline will serve as the crucial link, connecting a compressor station on the Maasvlakte to the P18-A platform, situated approximately 20 kilometers offshore. Allseas will utilize its advanced dynamically positioned S-lay vessel Lorelay for the pipelay, with additional construction support provided by Oceanic. The anticipated commencement of activities is slated for 2025.

Expressing enthusiasm for the project, Allseas Chief Executive Pieter Heerema highlighted the pivotal role of the company's offshore installation capability in ensuring the successful execution of this groundbreaking initiative. He reflected on Allseas' pioneering legacy, citing Lorelay's historic achievements in the Dutch North Sea in the 1980s. He emphasized the vessel's continued significance as it prepares to undertake the installation of the first-ever carbon capture pipeline, affirming Allseas' enduring commitment to innovation and the enhancement of its vessels' capabilities.

Porthos, a collaborative effort involving EBN, Gasunie, and the Port of Rotterdam Authority, aims to facilitate transport and storage services for various companies within the port of Rotterdam, including Air Liquide, Air Products, ExxonMobil, and Shell. These companies are set to invest in their own capture installations to provide the CO2 supply.

The project's primary objective is the transportation of CO2 through the port of Rotterdam to depleted gas fields in the North Sea, where it will be securely stored at a considerable depth of 3 to 4 kilometers below the seabed.

Following the recent final investment decision, Porthos announced plans to award contracts crucial for the project's realization. The construction phase is scheduled to commence in Rotterdam in 2024, with the system expected to be fully operational by 2026, leading to an approximate 2% reduction in the Netherlands' annual CO2 emissions. This milestone underscores the nation's dedication to advancing sustainable practices and reducing its environmental footprint.
