The UK oil and gas company has awarded Allseas the engineering, preparation, removal and disposal contract for the near 13,000-tonne topsides.
Heather is a fully integrated offshore installation consisting of modular topsides and piled steel jacket, located approximately 460 km northeast of Aberdeen in a water depth of 143 m. It is a fixed installation providing manned production, drilling, and utilities facilities.
Preparations will begin next year with the lift itself scheduled for 2025.
