NEO Energy has taken the decision to decommission the subsea installations, pipeline & umbilical and well associated with the Victoria Field.
The Victoria gas field lies in the UKCS Block 49/17a in the southern North Sea, with the water depth along the pipeline varying between 21 to 27 m Lowest Astronomical Tide (LAT).
The existing Victoria subsea infrastructure is a tie-back to the ConocoPhillips owned Viking BD skid. Production from Victoria commenced in October 2008, with gas being exported to the Theddlethorpe terminal via the ConocoPhillips operated Viking B complex.
The Victoria subsea system consists of:
- One subsea production well complete with protective structure;
- One production gas flowline;
- One subsea umbilical designed to provide hydraulic control, electrical signal and chemical injection cores;
- Spools for Victoria development (of similar construction as the pipeline), totalling approximately 177 m:
- Victoria tree to Victoria valve skid, approximately 27 m;
- Victoria valve skid to production pipeline, approximately 72 m, split into two sections;
- Production pipeline to Viking DB valve skid, approximately 78 m, split into three sections.
- Two pipeline end valve skids (one at Victoria field location and one adjacent to the Viking BD platform location) to provide flowline isolations, tie-in points, and control tie-ins (both structures are piled);
- Single subsea gas meter located on the Victoria skid;
- 153 mattresses at Victoria well location, at the pipeline crossing of Viking BD to AR pipeline and at the Viking BD skid location adjacent to the Viking BD platform;
- Unknown number of grout bags used in the construction of crossing over Viking AR 24” and 3” lines, and to support the swan neck spools at the valve skids.
The Cessation of Production (COP) was approved in January 2016.
NEO Energy submitted draft Decommissioning Programmes (DPs) for Victoria to the Department for Business, Energy and Industrial Strategy (BEIS) in December 2020, in accordance with the provisions of the Petroleum Act 1998, for consideration by the Secretary of State for BEIS. It is a requirement of the Act that interested parties be consulted on such decommissioning proposals.
Public Consultation on the Victoria DPs opened on 17 December 2020 and closed on 29 January 2021.
If you have any questions about the Victoria DP you can contact Lynne MacPherson, Assets & Operations Manager, NEO Energy, 9th Floor, The Silver Fin Building, 455 Union Street, Aberdeen, AB11 6DB.
