Costain Wins EPC Contract Extension with Perenco

Costain, the engineering solutions provider, has been appointed by independent oil & gas company Perenco to deliver Engineering, Procurement and Construction ('EPC') services for the environmental upgrade of the Dimlington gas terminal on Humberside.

The contract is worth approximately £30 million to Costain, and demonstrates the successful progress made in the development of Costain's offering in complex oil & gas services. The project will involve the upgrade of Perenco's refrigeration system at Dimlington to ensure it complies with new environmental legislation coming into force on 1 January 2015. It builds upon the innovative Front End Engineering Design ('FEED') solution Costain previously delivered for Perenco after the Group's original appointment in 2012.

Andrew Wyllie, Chief Executive of Costain, commented:

"We continue to expand our capabilities in complex design and procurement in the oil & gas sector. Building on the innovative FEED solutions already provided, we now look forward to delivering the implementation phase of this investment in energy provision for the UK."
