two.1.4) Short description

GNI and GNI (UK) are seeking experienced EPCS contractors to deliver a series of critical infrastructure upgrades as part of the SWSOS Decarbonisation Programme, a cornerstone of our commitment to achieving Net Zero by 2050. This tender covers multiple work packages, including the design, procurement, construction, and integration of new electric drive compressor halls across operational sites in Scotland. The successful contractor will manage complex interfaces between new and existing assets, ensuring seamless integration of mechanical, electrical, and control systems, while adhering to stringent cybersecurity and safety standards. This initiative represents a strategic investment in sustainable energy infrastructure and offers an opportunity to collaborate on projects of significant scale and impact within a multinational framework.

SCOPE OF REQUIREMENTS:

The scope of this tender encompasses overall project management and delivery across multiple work packages, including but not limited to the following:

• Detailed Design Procurement

o Procurement of detailed design for new compressor halls, based on the GNI suite of functional specifications.

• Materials Procurement

o Mechanical materials: high-pressure pipework, valves, and fittings.

o Electrical materials: interconnecting cabling and junction boxes.

o Instrumentation materials: transmitters and data cabling.

Note: The second-stage tender process (CFC) will confirm the final requirements and clarify the full scope boundaries for the electric motor drive (EMD) package and the contractor's scope.

• Construction Activities

o Construction of new compressor halls.

o Completion of all civil works, including excavations, foundations, structural steel, compressor foundations, and ancillary electrical buildings.

o Installation of interconnecting pipework, electrical and control cabling, and junction boxes.

• Integration and System Tie-ins

o Integration of new electric drive compressors into the existing fleet of gas turbines.

o Mechanical, electrical, and control system tie-ins at operational compressor stations across GNI UK sites in Scotland.

• Security and Cybersecurity

o Installation of security systems and implementation of cybersecurity controls in line with GNI specifications.

• Testing and Commissioning

o Full responsibility for FAT and SAT activities.

o Commissioning and start-up of all new systems.

Additional Scope Notes:

• GNI may procure electric motor drive (EMD) packages separately.

• GNI will manage all permitting and planning permissions.

• GNI will separately upgrade incoming site electrical supply to power the new EMD packages.

Indicative EPCS Scope Boundary: The EPCS scope is envisaged to cover all elements required for the delivery of an electric drive compressor station as outlined above.

A more detailed scope is provided within the Appendices of the Qualification System Questionnaire documents.
