Two new modules from A to Z

The contract was awarded in 2016 and included engineering, procurement, construction and installation work of two new modules for the Heidrun platform. The smallest module, the H25, was delivered and installed offshore in spring 2018. The larger M40 module left the yard in Haugesund for installation offshore in late summer 2019.

In addition, Aibel has been responsible for clearing the area on Heidrun and manage the integration on the platform.

The project was managed from Aibel’s office in Oslo, where engineering and procurement took place, while construction work was carried out at the yard in Haugesund. At most, 700 employees were working on the project.

The project was completed late 2020.
