24/033 - Qualification System for the provision of Engineering, Procurement and Construction Services for South West Scotland Onshore System (SWSOS)

Gas Networks Ireland needs Engineering, Procurement, and Construction Services (EPCS) for the South West Scotland Onshore System (SWSOS) Decarbonisation Programme. This involves the design, procurement, construction, and integration of new electric drive compressor halls at operational sites in Scotland. The scope includes detailed design procurement, materials procurement (mechanical, electrical, instrumentation), construction activities (civil works, pipework, cabling), integration and system tie-ins with existing gas turbines, security and cybersecurity installations, and full testing and commissioning. The project aims to upgrade critical infrastructure to achieve Net Zero by 2050. Award criteria will be based on Price and Quality.

25/002 - Provision of Onshore and or Nearshore Inspection Services

The Contracting Entity is seeking applications from suitably experienced inspection companies to carry out offshore, nearshore and onshore inspection surveys of two submarine gas transmission pipelines each approximately 200km long, Scotland to Ireland from shore to shore, and one spur and one umbilical approximately 11km long to the Isle of Man. The network cathodic protection is provided by means of sacrificial aluminium alloy half shell bracelet anodes. The network entire lengths are either trenched, or rockdumped in lieu of trenching. The seabed is varied and includes sandwaves towards the Scottish end. The maximum water depth is approximately 140 metres. The inspection scope requires vessels equipped for visual inspection, acoustic examination, cathodic protection monitoring and the assessment of the disposition of the pipeline relative to the seabed. There is also a requirement for a capability for conducting intervention tasks involving the removal of seabed debris and/or freespan rectification and maintenance capability for a subsea tee in approximately 30 metres water depth. There is a further requirement for a capability to mobilise an offshore diving spread to conduct subsea intervention tasks using divers. There will also be a requirement to mobilise at short notice for unplanned debris surveys of the pipelines as required.

25/059 - Qualification System for Telecoms Infrastructure Design, Build and Maintenance

Gas Networks Ireland needs telecommunication services for a qualification system over 10 years. The services are divided into three lots: Lot 1 for civil engineering services to support fibre network maintenance and new connections, Lot 2 for comprehensive network design and surveying services for fibre infrastructure deployment, and Lot 3 for comprehensive GIS Design and Asset Management System services for fibre infrastructure deployment. Offers will be evaluated based on Price and Quality.
