Costain will showcase its engineering design, procurement and construction expertise in the oil and gas sector when it presents at Offshore Northern Seas (ONS) in Stavanger in Norway on 30 August.
ONS is one of the key industry exhibitions and conferences for the offshore oil and gas industry, attracting nearly 100,000 delegates from across the global oil and gas industry.
Costain’s Stuart Campbell, Project Director on Perenco’s Dimlington Terminal Freon Replacement Project, will give a presentation in one of the technical sessions taking place at the four-day event. Stuart’s presentation will be based on the theme of ‘Production Optimisation and Reduction of Environmental Impact’. It’s an area that Stuart and his team know a lot about: the project recently won Project of the Year in the £30-£50 million category at the Construction News Awards 2016, as well the Industry Project of the Year at the Institution of Chemical Engineers (IChemE) Global Awards 2015, while Stuart walked away with the Industry Leader of the Year award.
The terminal originally used refrigeration units to chill gas during processing to ensure the sales gas product met the required specification for the national gas transmission system. The units used a refrigerant which is now being phased out due to the Montreal Protocol on Substances that Deplete the Ozone Layer.
Costain helped Perenco select an alternative, innovative application of technologies to deliver a low cost, high reliability solution. Costain’s design also reduced the carbon footprint of the project, avoided having to reduce the terminal processing capacity and significantly shortened the project programme, allowing all parties to meet the legislative deadline. As well as ensuring compliance with the legislation, Costain’s solution increased the site’s efficiency and eliminated the need for costly plant shutdowns. Costain’s solution reduced the initial capital costs by over 60% and helped to retain plant flexibility for economic processing of future gas field finds.
“The modifications to Perenco’s Dimlington terminal were a major environmental project, eliminating the use of Hydrochlorofluorocarbons (HCFCs) in line with legislation, and one which Costain was very pleased to be involved in. I’m looking forward to presenting at ONS 2016 and talking about how we identified and achieved radical solutions to deliver project success within the aggressive time and budget constraints,” said Stuart.
