Survey - Morecambe - Round 4 Proposed Wind Farm Development - Flotation Energy



Mariners are advised that survey vessel and equipment will be used in the offshore area in the Irish Sea, west of Blackpool, UK. The offshore geophysical survey work will be carried out by MMT using survey vessels Northern Franklin Cal Sign: OZIH2. Work will commence in the UK waters from 15th October.


During this survey the vessel will be deploying underwater survey equipment at which such times, the survey vessel will be restricted in its ability to manoeuvre and approaching vessels are requested to pass at a safe speed and distance. Mariners are advised to keep an aft safety clearance of the survey vessel no less than 500m

 

The vessel will be towing 3 items of equipment and they will be approximately 150 m astern of the vessel. The vessel towing speed will be approximately 3.5-4.5 knots.

 

Morecambe is a 480MW offshore wind farm, and is owned by Offshore Wind Ltd (OWL) a joint venture between Cobra Instalaciones Servicios, S.A., and Flotation Energy plc. This survey is the Phase-1 Geophysical Ground Investigation of the wind farm site.

 

The geophysical survey work will be conducted with hull mounted Multibeam sonar and a sub-bottom profiler with towed sidescan sonar and TVG (dual magnetometer). Additional geo-sparker and PAM equipment will also be towed from the vessel.

 

The geophysical survey work in the area will be carried out by MMT using offshore survey vessel Northern Franklin.

 

An Offshore Fisheries Liaison Officer will be onboard during the works, contactable on VHF channel 16

Havhingsten Cable Installation (Loughshinny, Ireland)



Please be advised that installation of the Havhingsten fibre optic telecommunication cable system in the Irish Sea inside of the Irish 12 nautical miles is planned to occur in December 2021. Works within Irish Territorial Waters will start only after the Foreshore Licence has been issued. Foreshore Licence application number FS006915. Works are planned to start on 13th December 2021.


Please be advised that installation of the Havhingsten fibre optic telecommunication cable system in the Irish Sea inside of the Irish 12 nautical miles is planned to occur in December 2021. Works within Irish Territorial Waters will start only after the Foreshore Licence has been issued. Foreshore Licence application number FS006915. Works are planned to start on 13th December 2021, the duration of the works is provided below.

 

The supplier of the Havhingsten cable is Alcatel Submarine Networks (ASN). The shore end contractor is Maritech. Intertek are the environmental and permitting consultants.

 

The entire cable system will comprise marine elements that pass from Denmark to the UK (NE region); from the UK (NW) to the Republic of Ireland; with two segments installed into landfalls on the Isle of Man. 

 

The cable route for the western Irish Sea region is shown within the attached NtM, with landing at Loughshinny in Ireland. Works in October 2021 were completed to install up to the Irish 12 nautical miles boundary.

 

The cable will be recovered with a Grapnel Run and a Splice will be performed to restart/complete the operation. The cable will be buried using a cable burial plough until the Bighted or direct Shore End Landing location at Loughshinny where the cable will be pulled from shore to reach the Beach Man Hole (BMH). After this step the main lay vessel will be free from cable operation and will sail away for other activities.

 

Installation will be via industry standard burial tools including water jetting, divers and ploughing. Target cable burial depth is 1.5m below seabed level in the region. The target burial depth on the beach is 2m or until bedrock.

 

It is anticipated that installation operations in Irish waters will occupy up to a maximum 500m width (250m either side of cable). The cable itself will occupy only 40mm of the seabed.

 

Expected speed of installation will be approximately 17 km per day.

 

Planned durations of works are as per below (subject to weather):

Navigation Warning - 08th January 2021

 

Mariners are advised that the remnants of a Wave Rider Buoy sinker weight and partial rigging are located within the Triton Knoll Offshore Wind Farm Construction site at the following location;

 

53° 30.442N 000° 50.564E

 

It is advised that the partial rigging could potentially be floating up to 9.7m above the seabed, reducing the navigable safe water in the immediate area to 10m LAT.  Mariners are advised to avoid the indicated position by 250 metres.

 

Possible Dangers to Navigation - Properties of the polypropylene show that the rope is buoyant, this makes the line sensitive for thruster currents. Taking the site water depth into consideration (19.7m LAT) and the maximum expected height above seabed of the rope 9.7m the line is expected to be floating submerged at approximately -10m LAT. In addition, it is noted that over time sediments will be trapped between the fibres and the heavier rope may finally sink. The polypropylene rope may impose a risk to foul propellers / propulsion of vessels due to the buoyant nature of the rope. As the rope is submerged at a depth of ~-10m LAT the risk is considered minimum for vessels with a shallow draught (<5m) and medium for a vessel with a deeper draught (>5m). Over time sediments will be trapped between the fibres and the heavier rope may finally sink thereby reducing the risk to propellers/propulsion of vessels. The clump weight itself (chain) is expected to have sunk into the seabed and has no significant height above seabed. In addition, the edges of the clump weight are mostly rounded (chain), the risk the clump weigh imposes to fishing activities/gear is therefore considered to be minimal.

 

Navigation Warning - 16th March 2021

 

Mariners are advised that two UXO targets have been confirmed within the Triton Knoll Offshore Wind Farm Array.

 

Mariners are advised that the two confirmed targets are located within 20 metres water depth (LAT) and a 10 metre radius exclusion zone is required around each target.  The following table provides the coordinates and a description for each target.

 

Description of Target Latitude Longitude

Water Depth

(LAT) Metres

Required Exclusion

Zone (Metres Radius)

Archaeological - The item is thought to be an air-delivered bomb.  It appears to be in a stable condition and is resting on the seabed.  Marine growth and concretion cover the body, indicating it has been in situ for a significant duration. The tail section of the bomb is missing, which is typical of unexploded bombs from WWII found in these circumstances and there is a significant hole in the case. The dimensions and characteristics gathered are consistent with a 500kg German bomb. Considering the state of the bomb the Net Explosive Quantity of the bomb is likely to be <5kg. 53°31'50.249"N 00°47'45.908"E 20 10

Seabed instrumentation frame deployments - South Stack Irish Sea



Two seabed instrumentation frames with associated ground lines and clump weights will be temporarily deployed for a period of approximately 5-6 weeks, assuming suitable weather conditions for recovery operations.


Each ballasted frame weighs around 370kg, measures approximately 1.5m x 1.5m x 1.5m and is connected to a 100kg clump weight and remotely actuated pop-up buoy via a 100m wire ground line.

 

Once installed in the Morlais demonstration zone the frames will sit on the seabed at depths of at least 30m, with no surface infrastructure such as buoys or markers. Vessels will be able to pass safely through the area and above the frames. Use of static or mobile benthic fishing gear in the immediate area should be avoided to avoid the risk of snagging.

 

Three possible deployment locations are listed for the two seabed frames: a final pre-installation survey by subsea video camera will be completed at these locations before the equipment is deployed on the two most appropriate locations. This notice will be updated with the as-deployed locations.

The survey will be undertaken from one survey vessel, KARELLE, and will involve the collection of data of detected vessels and marine users through use of onboard radar, AIS and visual survey methods.

 

The survey will collect data within the two proposed main offshore bidding areas for the Morgan and Mona projects within which the array for each project will be located. The extent of the areas in which the survey vessel may be located during the survey are shown in Figure 1 and Figure 2 in this NtM with accompanying coordinates. The survey vessel will roam and/or remain nominally static within the Morgan and Mona project areas for approximately 28 days (14 days in each area) depending on weather conditions. Dates may be subject to change. The survey vessel will operate on a 24hr basis and display appropriate day shapes (mast head signals visually indicating the status of a vessel to other vessels on navigable waters during daylight hours) and lights at all times during operations.

 

All vessels are requested to maintain a safe distance from the survey vessel at all times.

 

This is the first of two marine vessel traffic surveys to be undertaken, with the second anticipated to be undertaken in July/August 2022.

Shetland HVDC Link - Presence of HDD Exit Ducts at Noss Head



This notice is issued to make mariners aware of the completion of the HDD operations and the presence of three ducts protruding from the seabed at Noss Head.


The Shetland HVDC link is a critical electricity transmission link and will form part of the electrical transmission grid that is essential to the transport of renewable energy between the locations where it is generated and areas of demand, and the delivery of both Scotland’s and the United Kingdom’s 2030 climate change targets. As part of the installation schedule Horizontal Directional Drilled (HDD) exit points have been installed at Noss Head by NKT, on behalf of Scottish Hydro Electric Transmission.

 

The HDD exit points are located approximately 400m offshore in around 20m depth of water. This Notice is issued to make mariners aware of the presence of three ducts protruding from the seabed at this location.

 

Three steel pipe ducts have been installed with trajectories that emerge from the seabed around 400m offshore. The ducts have been pushed out from each of the three HDD exit points and extend up to 4m into the water column at an angle of approximately 9º to the horizontal as shown in the diagram and illustrations within the attached Notice to Mariners.

 

The HDD installation operations are now complete, and the moorings and anchors used to assist with diving operations for the HDD installation activities have been fully recovered. Therefore, the HDD exit point area is no longer identified by marker buoys.

 

It is recommended that mariners make note of the HDD duct locations and remain vigilant of the seabed protrusions until June 2022, when further installation works are scheduled.

These locations are all within the Berwick Bank Wind Farm (BBWF) in the outer Firth of Forth on the east coast of Scotland. It should be noted that the near-bed frame will only be situated at one of these three sites at any one time.

 

The equipment will be deployed during October 2021, with an estimated start date for deployment set for the 14th October 2021. However, this may be subject to change due to weather and/or operational delays. The stumpy moorings will be deployed for 12 months with maintenance and monitoring completed at each three-month interval. The one near-bed frame will be deployed for three months at two sites and 6 months at one site, equating to a deployment duration of 12 months in total.

In addition, although listed as exposures on the chart, there are areas of shallow burial at KP10 and a cable exposure on the interconnector cable within the site.

 

The exposed/shallow burial areas are shown as the coloured dots on the cable route highlighted in a black box.  Equitix (Greater Gabbard OFTO) have asked that all Fishermen operate with caution when fishing anywhere on the cable route and particularly the areas that are shallow buried around KP10.’

 

Coordinates of exposed/shallow burial areas are shown on the attached chart.

 

The OFTO is updating its risk assessments to determine the extent of remedial measures that may be required. Equitix intend to provide an update on remediation after the risk assessment exercise is complete.’
