Azeri, Chirag Gunashli Full Field Development Phase 3 Environmental Socio-economic Impact Assessment Final Report 5.3 Offshore Platforms 5.3.1 Overview The Phase 3 offshore platforms will consist of a DUQ platform bridge linked to the PCWU platform (Figure 5.4). Together, the two installations will provide the necessary facilities for the production and partial processing of hydrocarbon products prior to its export to shore, in addition to drilling and water injection requirements. The following sections summarise the platform facility design/layout, the fabrication/construction and onshore pre-commissioning activities, plus the load-out and offshore installation, hook-up and commissioning activities. Operational activities of the platforms are described in Section 5.5.

It will provide 12 well slots for the pre-drill programme. Pin Piles shall be used for the docking guides for the installation of the DUQ jacket. The template will be constructed from high-grade marine steel, with corrosion protection provided by anti-corrosion / anti-fouling paint and zinc-aluminium sacrificial anodes.
