McDermott International, Inc. announced it has been granted approval from Beowulf Energy LLC and Preem AB to commence the front-end engineering design (FEED) phase for its Residue Oil Conversion Complex (ROCC) project. The project will be implemented at the Preem refinery in Lysekil, Sweden. The FEED phase follows the sizeable technology license agreement between Chevron Lummus Global (CLG), McDermott's joint venture with Chevron, and Beowulf Energy in 2017 related to CLG's LC-SLURRY Unit and the subsequent pre-FEED work executed by McDermott. The award marked the first LC-SLURRY technology license since adding the maximum residue conversion technology to the CLG portfolio. McDermott previously worked at the Preem refinery as the FEED and Engineering, Procurement, Construction management (EPCm) contractor for the hydrocracker project, which was also based on CLG technology, between 2003 and 2006. The FEED will be executed from McDermott's downstream Centers of Excellence in The Hague, The Netherlands and Brno, Czech Republic. Work on the project will begin immediately and is expected to be completed in the fourth quarter of 2020.
