Construction work for gas pipelines

Description

EP UK Investments Ltd (EPUKI) on behalf of EPKL is planning a new high-pressure natural gas pipeline from the existing Belfast Transmission Pipeline to Kilroot Power Station in Northern Ireland. The objective of the Proposed Development is to provide a gas supply to the existing diesel fuelled Open Cycle Gas Turbines (OCGT) peaking plant at the Kilroot Power Station to enable the units to switch from diesel to gas fuel, and additionally to support potential future development of new natural gas fired generation. Subject to planning it is proposed to have the power station operating on gas by the end of 2022. The supplier will be required to provide full turnkey Engineering Design, Procurement and Construction) (EPC) Contract for the delivery of an Above Ground Installation (AGI) at Marshallstown, approximated 2.7 km of high-pressure gas pipeline, a second AGI at Kilroot and adjoining PRS (Pressure Reducing Station) at Kilroot. The scope of services shall include the project management, design, procurement, manufacture, shop testing, inspection, delivery and unloading, construction, installation, welding, health and safety management, painting/coating, inspection, testing and commissioning of the new gas pipeline, the Marshallstown AGI, the Kilroot AGI and the Kilroot PRS. The project will need to meet the requirements of United Kingdom, Northern Ireland, European and international regulations, orders, directives, BREF and standards, and comply with local permits, licences and codes. The Marshallstown AGI and high-pressure pipeline, greater than 12 ” diameter and > 50 bar pressure, will be constructed on a green field site and the Kilroot AGI and PRS will be constructed on brown field site at Kilroot Power Station. The majority of the pipeline will be installed underground using an ‘open cut’ method, where a trench is excavated, and pipe laid within it. Once the pipeline is installed, the trench will be back-filled and the land reinstated as far as possible to its original condition. Crossings of roads, including the A2, and any other obstacles will be by underground tunnelling or drilling to avoid disruption of traffic or road closures.
