Free Span - Cyrus Manifold



Reconfiguration work at Cyrus has left unprotected spools at the Manifold location which increase the risk of snagging. The proposal is to move the as-found mattresses (3m x 6m x 0.15 m) with a submerged mass of approx. 3 te. This reconfiguration will reduce the restraint on the seabed spool section, thus increasing the flexibility of the system and reducing pipe stresses. This section of spools will therefore be unprotected from seabed interaction posing a risk of snagging.

Deployment of FLiDAR buoys - Blyth NOAH met mast site



Fugro GM Marine Limited (Fugro) to carry out deployment of two floating LiDAR buoys at the NOAH mast offshore Blyth. The deployment of the equipment is is estimated week commencing 20 November and equipment will remain on site for an estimated duration of 30 days. Deployment operations are expected to take one day. Operations will be conducted with the Tees Guardian call sign: 2IJH2 and will involve towing the equipment from the Port of Blyth to the deployment site.


In addition to the deployment of two new buoys, operations will include the recovery and removal of a LiDAR buoy that is presently deployed at the same site.

The equipment will be located at the Blyth NOAH offshore Met Mast validation site.

 

The equipment is an integrated Seawatch Wavescan buoy and ZX 300M LiDAR; the purpose of the equipment is to collect oceanographic and meteorological data using a single platform. The equipment is supplied and charged by an onboard power system which uses methanol fuel cells and solar panels to recharge onboard lead acid batteries.

 

The equipment is equipped with a F1 (5) Y 20 s light with 4-5 nautical mile range; the light is mounted at the top of one of the masts, approximately 4 m above sea level.

The Northern Producer FPF has been removed from it’s moorings and towed to port for decommissioning but the subsea assets within the Northern Producer FPF 500m zone will remain in place on the seabed and could pose a snag hazard to fishermen


The Northern Producer FPF has been removed from it’s moorings and towed to port for decommissioning but the subsea assets within the Northern Producer FPF 500m zone will remain in place on the seabed and could pose a snag hazard to fishermen therefore the Thistle Alpha Platform ERRV will act as a guard vessel until the 500m zone clearance is performed in 2022.

 

This includes the 8 No Risers draped over the Mid Water Arch (MWA), the MWA Clumpweight Guide Frame, the Riser Base Structure (RBS) and the surface laid pipelines / Umbilicals.  The MWA will remain in the water column at a depth of 112m and will remain tethered to the seabed via the clumpweight guide frame. The risers will remain draped over the MWA with one end on the seabed and the other end will remain connected to the RBS so that they remain stable. The existing stabilisation mattresses will remain in place over the surface laid pipelines/umbilicals.

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.
