LEIDEN, the Netherlands – Spirit Energy Production UK has awarded contracts to two companies covering removal and disposal services for various North Sea platforms.

Heerema Marine Contractors will work with DeepOcean, the subsea asset removal contractor, to deliver decommissioning of the platforms.

The EPRD (engineering, preparations, removal, and disposal) contract includes firm work plus an optional scope that can be called-off by Spirit. Heerema will manage its responsibilities from its offices in Leiden and London.

The firm EPRD work relates to the Audrey A, Audrey B and Ensign platforms in the UK southern gas basin, while the optional work includes five further platforms in the southern UK and Dutch North Sea.

Heerema’s scope covers removal and recycling of the platform topsides and substructures, with DeepOcean responsible for removing and recycling all subsea facilities at the fields.

Combined weight of the firm-scope topsides and jackets is around 7,000 metric tons (7,716 tons), and the structures will be recycled in the UK. The platforms are in water depths ranging from 23-26 m (75.5-85 ft).

DeepOceanwill lead its part of the program from its office in Aberdeen. The company’s firm scope involves decommissioning of subsea equipment at the A-fields and Ensign, while its optional work includes up to ten fields in the southern North Sea region.

The company says it will deploy various vessels to remove items including subsea structures, rigid pipelines, flexibles, umbilicals and mattresses, and will also provide associated engineering and project management services.
