EnQuest extends CB&I contract for late-life Kittiwake platform transition in UK North Sea

Independent energy producer EnQuest has extended its contract with CB&I’s Asset Solutions business to manage the Kittiwake platform in the UK North Sea. The revised agreement shifts the firm's mandate from late-life asset management to overseeing the cessation of production and the eventual decommissioning of the facility.

An agreement has been reached between independent energy operator EnQuest and engineering service provider CB&I to prolong the Duty Holder contract for the Kittiwake oil platform in the UK North Sea. Under the renewed terms, CB&I's Asset Solutions business will retain operational control of the facility through its final operational phase, guiding the platform through its cessation of production (COP) and eventual decommissioning. Headquartered in London, EnQuest specializes in optimizing late-life oil and gas fields, while CB&I's Asset Solutions division-formerly a business unit of Petrofac—provides outsourced operation, maintenance, and engineering services to upstream energy developers. This development continues a long-term partnership on the asset that has been in place since 2003.

The contract extension is notable as it represents a strategic shift from active, life-extension management to the terminal phase of a mature North Sea asset. Serving as a central processing hub for several subsea tie-backs within the Greater Kittiwake Area, the platform's smooth transition to decommissioning is critical to maintaining regional environmental compliance and cost-efficiency. By securing a single partner to oversee both late-life extraction and the subsequent decommissioning prep, EnQuest minimizes the operational and safety risks associated with changing hands during a technically demanding phase of the asset's lifecycle.

From an industry-wide perspective, this development reflects a broader regulatory and commercial trend across the UK Continental Shelf, where aging infrastructure is increasingly transitioned to specialized third-party operators. Regulators have placed a high premium on safe, continuous, and cost-effective decommissioning procedures. The long-standing, incident-free safety record of the onboard crew supports the viability of outsourced duty holder models, which are expected to see higher adoption as more North Sea assets approach their economic limit over the coming decade.

For energy investors and oilfield service providers, the agreement underscores the commercial value of end-to-end lifecycle capabilities. As the basin matures, the capability of oilfield service firms to seamlessly pivot from production enhancement to dismantling operations will be a key differentiator in capturing market share. For operators like EnQuest, outsourcing these liabilities to a trusted, long-term partner stabilizes financial projections and operational timelines during a period of high regulatory scrutiny and capital discipline.
