Allseas to Remove Heather Topsides for EnQuest

EnQuest has opted for Pioneering Spirit’s  single-lift technology for the removal of the Heather Alpha platform topsides in the UK northern North Sea.

The UK oil and gas company has awarded Allseas the engineering, preparation, removal and disposal contract for the near 13,000t topsides.

The award follows an intensive period of evaluation, negotiation, and clarification.

 

 

Heather is a fully integrated offshore installation consisting of modular topsides and piled steel jacket, located approximately 460km northeast of Aberdeen in a water depth of 143m.

It is a fixed installation providing manned production, drilling, and utilities facilities.

Preparations will begin next year with the lift itself scheduled for 2025. EnQuest filed its decommissioning programme for the Heather Alpha platform topsides to the UK’s authorities in April 2021. The plan was approved in July of the same year.
