Allseas has awarded Modern American Recycling Services Europe (MARS) with the contract for project management and engineering, receipt with load-in assistance, dismantling and disposal of EnQuest’s Heather Alpha topsides.
The contract was announced on MARS’ social media platforms, and will provide the chance for the company to participate in the decommissioning of the 13,000 t topsides.
As part of the project, EnQuest will make use of Allseas’ Pioneering Spirit, a 48,000t offshore construction vessel that is designed for single-lift installation and removal of offshore platforms as well as the installation of record-weight pipelines. The ship has proven its ability to lift entire topsides of up to 48,000 t and jackets up to 20,000 t in a single piece.
The vessel will be used to remove the Heather topsides in a single lift operation. Preparations for the lift will begin next year, with the lift itself scheduled for 2025.
Following this work, in subsequent years, M.A.R.S. will recycle the platform in compliance with international, national and local rules and regulations.
