Rig Site Survey - Scoter & Merganser



An anchoring conditions and debris Geophysical survey for the emplacement of a semi-submersible drilling rig is to be conducted at the Scoter and Merganser well cluster locations in UKCS block 22/30A by Fugro Galaxy.


Data acquisition will comprise of an anchoring conditions survey within an 10km x 6.125km greater working area, using towed side scan sonar, hull mounted multibeam echo sounder and sub-bottom profiler on Fugro Galaxy.

Pipeline Installation - Evelyn Field



Tailwind Mistral Ltd intends to install pipelines and umbilicals from the existing Evelyn Well EV01 to the GEEBB Manifold and the Triton riser base, this will comprise: 8" production line with 3" piggyback gas lift line, Control umbilical line.


The Evelyn field is located within UK licence P1792 approximately 7.5km to the South West of the Dana Operated Triton FPSO. The development will consist of a single gas lifted production well EV01.

 

The 8" Pipeline route runs from the Evelyn valve skid (EVVS) drill centre tie-in structure in a north east direction to a comingling tie-in structure (GEEBB) which will comingle production fluids from Gannet E, Evelyn and Bittern. The GEEBB structure will be located outside the Triton swing circle, but inside its 500m safety zone. The 8-inch pipeline will be trenched and buried using trench backfill material. Areas which are not trenched at the Evelyn and Triton approaches will be protected from fishing gear interaction and/or dropped objects by a combination of rock placement and concrete protection mattresses.

 

The 3" Pipeline route runs in a south westerly direction between the GEEBB tie-in and distribution structure to the Evelyn valve skid (EVVS) drill centre tie-in structure. The GEEBB structure will be located outside the Triton swing circle but inside its 500m safety zone.  The 3-inch gas lift pipeline will be piggybacked to the larger 8-inch production pipeline and will be trenched and buried using trench backfill material. Areas which are not trenched at the Evelyn and Triton approaches will be protected from fishing gear interaction and/or dropped objects by a combination of rock placement and concrete protection mattresses.

 

The 9.5 km control umbilical will be installed from the EVVS to the umbilical riser base at Triton FPSO.  The umbilical will contain a total of 16 cores and will provide hydraulic, electrical and chemical supplies from the Triton dynamic umbilical at riser base SY9516A to the EVVS and wells

Application for Offshore Development Area - Seagull Umbilical



Neptune E&P UK Ltd would like to request to establish an additional offshore development area in Block 22/29C for the Seagull Umbilical location.


The Seagull Field is located on UK licence P1622 Block 22/29C. 17km south of the Eastern Trough area Project (ETAP) Central Production Facility (CPF). Neptune will develop the Seagull reservoir as a subsea tie‐back to existing seabed infrastructure over the BP operated ETAP CPF. The development is high pressure and high temperature and Neptune is the Operator for the subsea development. Neptune will also drill and complete the Seagull Wells and shall retain overall Project responsibility.

The Seagull development will require installation of new subsea equipment as follows: Four Xmas Trees; a 4 slot manifold; a 17km control umbilical (including hydraulic, electrical and chemical supplies) direct from ETAP to Seagull; a 5km 10” production pipeline; a 5km 3.5” wash water pipeline from Seagull to the existing Egret manifold; and a Wye manifold adjacent to the existing Egret manifold, through which the new Seagull production pipeline will connect with the Heron cluster pipeline system connected back to the ETAP CPF. From ETAP CPF Seagull oil and gas will be exported to shore through the GAEL and FPS pipeline systems to the Kinneil Terminal onshore.

 

We already have an ODA established covering the Seagull drill centre and the Egret manifold and would like to request to extend the ODA to incorporate the entire Seagull works area. The extended Offshore development area will be required commencing from September 2021 ‐ March 2023.
