Costain, UK’s engineering solutions provider, has been awarded a contract by Total E&P UK for the construction of a hydrochloric acid dosing plant at the Shetland Gas Plant (SGP).

Costain said on Monday that the deal entails installation, tie-in, pre-commissioning and commissioning support.

The company said that this contract follows on from a previous award to Costain in June 2015 by Total for the provision of Engineering Procurement and Construction (EPC) services for design, construction, installation and pre-commissioning of a Condensate Mercury Removal Unit (CMRU) and a Subsea Control Unit (SCS) at the SGP in connection with its Edradour-Glenlivet Field Development.

The SGP project facilitates reception, processing and export of natural gas and its associated condensate from gas fields located to the west of Shetland, including Laggan-Tormore, Edradour, and Glenlivet. To remind, the Laggan-Tormore fields began production officially in May this year. The development consists of a 140-kilometer tie-back of four subsea wells to the onshore Shetland Gas Plant which has a capacity of 500 million standard cubic feet per day.

Frazer McKay, Costain Oil & Gas Sector Director, said: “We are delighted to have been awarded this additional scope at SGP. We look forward to integrating both projects at SGP to achieve a safe, successful and cost efficient delivery.”
