The Frigg Line exports gas from all connected fields. The TP1 Bypass and MCP01 Bypass operations isolated redundant facilities to allow subsequent decommissioning. |
 |
The Dunbar field, situated 22km south of Alwyn North, first produced oil/gas in 1994. Dunbar comprises a steel jacket platform together with drilling and accommodation facilities. Produced oil, gas and water is pumped back to the Alwyn platform via a 22km subsea multiphase pipeline. Throughout recent current drilling campaigns, the Transocean Sedco 706 semi-submersible has been anchored alongside Dunbar to provide Tender support services. |
 |
The Back Up Intervention Control System (BUICS), is Intended to temporarily replace the main Simian/Sienna and Sapphire Field Control System in the event of a total or partial failure of sub-sea umbilicals. There are two BUICS - one designed for the 830m water depth of the Simian/Sienna Field, and one for the 300m water depth of the Sapphire field. Both of these systems are retained on standby and may be mobilised and deployed individually. |
 |
The purpose of the Tern Incremental Project (TIP) was to substantially increase the capacities of the Production Water handling and Gas Compression facilities on the Tern Platform. |
 |
The Starling well fluids are brought onboard Shearwater A Platform through a new Riser. The well fluids are routed through a new ESD Valve and wet gas meter to tie-in points on the existing Production and Test Separator lines. The Starling facilities are contained in two prefabricated modules located above the existing Scoter Module. |
 |
The Penguin Field is located in Blocks 211/13a and 211/14 of the North Sea, and is tied back to the Brent C Platform via a pipe-in-pipe Production Pipeline and Control Umbilical. Provision was made in the Penguin design for future Gas Lift to the Penguin Drill Centre. New Topside and Subsea Gas Lift Facilities were provided to supply Lift Gas to the Penguins Field. A 4 diameter Gas Lift Pipeline was laid alongside the 66.7km Production Pipeline and tied back to the Brent C Topsides. Lift Gas is sourced upstream of the BC Export Gas Backpressure Valve. |
 |
The Penguins Field is located in the UK Northern North Sea, some 150km north-east of the Shetland Islands. It has been developed as a subsea cluster and is tied back to the existing Brent Charlie platform. The Penguins field is tied-bac via a single 16-inch diameter production pipeline to the Brent Charlie Platform, which at 65km created the longest sub-sea tie-back in the UKCS. The oil produced by Penguins is exported from Brent, via the Cormorant to Sullom Voe, and gas via the Brent system to St. Fergus. |
 |
The Otter Field is located in the UK Northern North Sea and was developed via a subsea tie back to the existing Shell Eider Platform. From Eider, oil and gas from Otter is exported via the North Cormorant to Sullom Voe and St. Fergus. |
 |
The Nelson Oil to Sea Project was part of a major Environmental Project to reduce the volume of Produced Oil discharged to Sea. In compliance with OSPAR regulations, Produced Water will be re-injected into the Wells with the objective of an 18% reduction in Oil to Sea. This objective was achieved with the installation of 2 new Booster Pumps located on a new Platform at ESDV Level. A new De-Sanding Package was located on a new Deck Extension at the NE Face of the Platform. |
 |
The Howe Project involved the brownfield installation of facilities on the Nelson platform including; 6 Production Line, CantileverSupport Platform, 3 Gas Line, ESDV and Riser Installation, Subsea Control Systems, Chemical/Methanol Injection and Allocation Metering. |
 |
As part of the Dunlin A- Leg Integrity Management programme, all Recoverable and Attic Oil stored in the platform Storage Cells was exported. The existing Import/Export system were decommissioned and the Import/Export Lines and Storage Cells were sealed. |
 |
The Cormorant A Booster Pump Replacement Project undertook the replacement of Isolation Valves VB-133, VB-135, HCV3 266 and HCV-3267 and associated Pipework below the Oil Booster Pumps CA-P3 200, CA-P-3210 and CA-P3 220 in Leg C4. |
 |
The MOPUP project provides robust and fit for purpose oil export facilities for the Brent field through to Cessation of Production. M1W Workscope replaced 1 x 100% Electrical MOL Pumps (with spare on the beach). The C4 Workscope replaced 2 x 50% Electrical Booster Pumps (with spare on the beach). |
| |
As part of the Brent Low Pressure Operation Plus (LPOP), the RB211 Turbine driven HP Compressor was replaced. The existing 6 wheel compressor assembly was replaced with an 8 wheel compressor assembly, satisfying conditions of lower suction pressure whilst maintaining discharge pressure. |
 |
As part of the Long Term Field Development (LTFD) plan a Fuel Gas Import (FGI) system was installed on Brent Bravo, Charlie and Delta. This system provides sufficient fuel gas to re-start the process following a production shutdown, utilising gas from the gas export pipeline. |
 |
The purpose of inspection of Brent charlie C4 Leg below the Gas Tight Floor was to prove the integrity of the identified lines. General Visual Inspection was also undertaken on the concrete Cell Structure and the Support Steel Structure. |
 |
The objective of the Brent Bravo Minicell Project’s first periodic inspection was to inspect the cell-fill oil lines, ballast water systems and redundant systems in the Minicell and Utilities Shaft below +76m to ensure that their integrity is maintained for the remaining operational life of the platform. This presentation provided an introduction to issues relating to Access and Inspection of the Utility Leg Minicell Structure and Pipework located in the Utility Leg of the Brent Bravo Platform. |
 |
This presentation describes the replacement and bypass of the Cell Import/Export Manifolds and 10 Cell Fill Lines located in the Utility Shaft of the Brent Bravo platform. The construction activity installs a new Import/Export Manifold at EL +87m, above the existing equipment at the Cell Fill Manifold level. |
