Pathway to Net Zero

Cygnus Electrification Study

Project description

Sealand Projects completed a feasibility study on the potential to provide carbon abatement to the Cygnus platform in the Southern North Sea through electrification.

The primary focus of this study was the opportunity for collaboration with Offshore Wind Farms within the vicinity, identifying the potential partners, boundaries and constraints in electrical, technical, regulatory and commercial terms.

Our scope

Identification of requirements for the Cygnus platform complex to help facilitate carbon abatement through electrification, considering opportunities with Offshore Wind and emerging technologies.

Collaboration with Offshore Wind Farm developers, transmission owners and supply chain. Engagement with regulators (OGA, TCE, BEIS, LCCC, OFGEN, National Grid) to determine opportunities, boundaries and constraints.
Pre-screen the options identified from a technical, legal and commercial perspective through a Class 5 cost estimate in addition to potential savings in carbon emissions compared against the ‘do-nothing’ approach.

Consider the implementation and development of emerging technologies and how this could extend the life of the Cygnus platform complex beyond CoP.
