Elgood - Blythe, Blythe - Thames, Pipeline Installation - Preparatory Works



This NtM relates to pre-lay surveys which will be performed along the Elgood to Blythe and the Blythe pipeline routes, with preparatory crossing activities on the latter.


Independent Oil and Gas (IOG) will be installing two gas pipelines in the southern North Sea, a 6-inch diameter pipeline from the Elgood Gas Field to the Blythe Gas Field and a 12-inch pipeline from the Blythe Gas Field to a tie-in point on the existing Thames pipeline. 

 

The area is in the UK Sector off the Norfolk coast.

 

During the second half of 2020 Subsea 7, on behalf of IOG, will be performing a pre-lay survey in advance of the pipeline installation, protecting sections of existing pipelines in readiness for the crossing by the new 12-inch pipeline, and the laying and trenching (burial) and partial connection of the two pipelines.

 

Pre-lay surveys with an ROV will be performed along both pipeline routes and preparatory crossing activities on the Blythe to Thames 12-inch pipeline route.

 

The works will be performed from the DP vessel Seven Navica,

Call-sign: M2HR7

LOA: 109 metres, Breadth: 22 metres

 

The vessel will be deploying a remotely operated vehicle (ROV) in the water, which will restrict its ability to manoeuvre and operations will be conducted on a 24-hour basis.

 

Whilst performing these activities the vessel shall either be static of moving at an approximate speed of <1 knot. Her heading may not be indicative of her direction of travel.

 

It is requested that all vessels within the area maintain a safe distance (500m) and pass at reduced speed.

 

Throughout these operations the vessel will be displaying the shapes and lights prescribed in the International Rules for the Prevention of Collisions at Sea (COLREGS) Rule 27, (Vessels not under command or restricted in their ability to manoeuvre).

Tolmount to Easington Pipeline Construction



Saipem Ltd will be performing offshore construction works, including pipelay activities, on behalf of Premier Oil Ltd on the proposed Tolmount Area Development located in block 42/28d of the Southern North Sea, approximately 50km North East of Easington


The works will be performed on the Tolmount to Easington pipeline route which is approximately 48 km in length and is located in the North Sea east of Bridlington. The pipeline will terminate offshore at the Minimum Facilities Platform (MFP) location.

 

Pipeline backfilling operations will shortly commence along the pipelay route.

 

On completion of ploughing and backfilling operations a rockdumping campaign will be conducted at the Rough and Cleeton pipeline crossing locations.

 

All vessels are requested to provide the ploughing and backfilling vessel “Far Samson” with a wide berth and not approach within one nautical mile.

 

The works will consist of:

  • Inshore dredging operations
  • Route preparations
  • Pipelay and associated support and completion activities
  • Subsea tie-in activities at the platform end pipeline termination

Two discrete operating areas are identified as follows;

  1. Inshore Dredging Operations Area
  2. Pipelay Operations Area

Operations will be conducted on a twenty-four (24) hour per day basis, seven (7) days per week. Any significant changes to the planned operational date ranges will be notified immediately.

 

Activity Planned Operational Date Ranges
Inshore Dredging Activities 04/04/20 to 17/07/20
Route preparations 01/04/20 to 06/06/20
Pipelay & Completion Activities 06/06/20 to 16/08/20

 

The pipelay corridor can now be collapsed from +/- 1000 m to +/- 300m up to the 12 mile territorial limit with immediate effect.

 

The exclusion zone at +/- 1000 m will be maintained from the pipelay route centreline around the Rough and Cleeton crossings to allow the rockdumping vessel Simon Stevin adequate sea room to perform her scope, including survey operations.

All locations detailed above have an established 500 meter safety exclusion zone, where the platform remains in situ nav aids are installed exhibiting the characteristics detailed below. It should be noted that Viking CD, ED & HD where removed from location in 2019, the 500meter safety exclusion zone remains.

  • All round white flashing light, Morse (U); flashing every 15s; with a 10nm nominal range and visible from 360 degrees in the horizontal plane
  • Virtual AIS marking transmitting on Navigational Warning Message Channel 21

All vessels are requested to maintain a wide berth from vessels engaged in platform removal and subsea operations when operating in the vicinity of the above locations detailed herewith and during the transportation phase into Great Yarmouth Outer Harbour.

 

The established 500 meter safety exclusion zone at the location of each platform to be removed shall remain enforceable until such time as notified otherwise (note the presence of the exclusion zones shall extend beyond the physical removal of the platform).

 

Following platform removal, Trawl snag hazards may remain at each of the locations until such time as a subsequent seabed clean up and debris removal campaign has been completed.

 

All mariners are advised to avoid the above mentioned locations and remain clear of the statutory 500m safety exclusion zone.

Cable Installation - Penguins (UK) - Snorre A (NOR)



Tampnet AS will in the period 1st of July until 30th of August 2020 perform an installation of a 90 km Submarine Fibre Optical Cable route between the Penguins Field and the Snorre field in the North


The cable will initially be surface laid and then buried, by means of trencher and cutting tools to ensure protection. In the time between the cable lay and burial the cable will be exposed until the burial operations are completed.

We advise that no fishing activity / trawling or using bottom gear in proximity to these areas must occur and to manoeuvre with caution to avoid damage to fishing gear or cable.

 

Deep Ocean will install the cable for Tampnet. Two vessels will be used in the operation:

  • Maersk Connector  Call Sign: OWEB2
  • Havila Phoenix  Call Sign: C6BD2

In addition we will use guard vessels to prevent damage to the exposed cable before burial is performed.

Breagh Pipelines - Exposed Fibre Optic Cable



The Breagh fibre optic cable (PL2770) is exposed on the seabed along various stages of the route between Redcar and the Breagh A platform.


A scallop dredger became snagged on an exposed section of the fibre optic cable in June 2019 causing serious damage to the fibre optic cable and subsequently had to abandon retrieval of his gear for safety reasons.  This notification is made to the fishermen, operating between Redcar and the Breagh A platform, to be advised that the fibre optic cable represents a serious snag risk to both scallop dredgers and static gear fishing in the vicinity of the line.

 

Fishermen are advised to stay away from the line to avoid the risk of becoming snagged on the unburied sections of cable.
