Floating LiDAR System - Seagreen Wind Energy



Seagreen Wind Energy Limited has replaced the Floating LiDAR System (FLS) at the location shown


The replacement FLS was deployed on the boundary of the Seagreen Alpha and Seagreen Bravo offshore wind farms in the Firth of Forth Offshore Wind Round 3 Zone off the east coast of Scotland. The replacement FLS is approximately 600m to the south-west of the previous location.

 

The FLS buoy will remain deployed for up to 1 additional year from this date. Service visits will occur at approximately 3-month intervals over this period.

 

The FLS is buoy mounted and is moored using 150 m long DIN 5683-II mooring chain Ø26 x 234 mm and 3 tonne concrete anchor. The buoy is powered by solar panels and micro wind turbine generators. The buoy is yellow (RAL 1023) in colour and will be clearly marked with two navigation lights (flashing amber, 5 flashes every 20 seconds, nominal range 3-6 nm visibility). The buoy is fitted with a Radar reflector. A service vessel will be on station for approximately four hours during service and recovery visits. Other vessels should maintain a safe distance when passing the vessel and should pass at lowest possible speed to avoid vessel wash effects.

Survey - Sofia Offshore Wind Farm



Fugro continue with Offshore Site Investigations along the export cable corridor of the Sofia Offshore Wind Farm (SOWF), with works expect to run until July 2020.


Fugro continue to undertake Geotechnical Investigations at the nearshore area of the SOWF export cable corridor using the Jack Up Barge 'Haven Seariser'.  Operations commenced on the 26th June are expected to run through to the end of July 2020.

 

Due to geotechnical vessels having limited manoeuvrability whist working in DP mode, it is requested that all vessels operating within this area maintain a safe operational distance, in line with standard procedures i.e. a C.P.A of 500 m, which is included in the survey area buffer of 2,000 m (coordinates below).  Geotechnical operations will be undertaken on a 24 hour basis, with a crew transfer vessel operating twice a day to and from the Jack Up Barge 'Haven Seariser'

 

All survey durations are dependent on prevailing weather conditions and work progress.

 

The guard vessel ‘Margaret Mary’ will provide additional support on site where necessary.  All vessels can be contacted on VHF channel 16 throughout the works for any further information.

 

The following vessels will be operational on site during these works;

Surveys - Norfolk Vanguard & Norfolk Boreas Windfarms



MMT have been contracted by Vattenfall Windpower Ltd to perform survey for the planned transmission assets linking the Norfolk Vanguard (NV) and Norfolk Boreas (NB) windfarm areas to shore.


Project Description and Survey tasks

During this survey the vessel will be deploying underwater survey equipment. During such times the survey vessels may have restricted ability to manoeuvre and other vessels are requested to pass at a safe speed and distance (at least 500 m). The vessels will monitor VHF Channel 16 at all times.

 

Geophysical survey with towed equipment will be performed along export cables and at Offshore Sub Stations (OSS). Equipment to be used: singlebeam echosounder (SBES), multibeam echosounder (MBES), side scan sonar (SSS), magnetometer (MAG) and sub bottom profiler (SBP). The scope will also include an environmental survey to map the presence of Sabellaria in the Haisborough, Hammond and Winterton (HHW) Special Area of Conservation (SAC). This shall also entail geophysical surveys using singlebeam echosounder (SBES), multibeam echosounder (MBES), side scan sonar (SSS) within the HHW SAC area, additionally targeted sediment sampling and/or environmental mapping using a Drop Down Video system at yet to be determined positions will be completed.

 

Timeline

Survey works will commence on the 2nd June and is scheduled to end at the 14th August (subject to change, ultimately dependent on the weather situation). Survey works will initially be carried out in blocks 1 and 2 and then move to blocks 3 and 4 on the 6th of June and then continue from west to east for the remainder of the period. Nearshore survey is scheduled to commence on the 28th of June and end in the end of June.

 

Fisheries Liaison

A shore based Fisheries Liaison Officer (FLO) will be available during the course of the project – details below.

With regards to nearshore activity (inside B04), there will be an offshore Fisheries Liasion Officer on the SeaPal who can be contacted via the vessel detail below.

Subsea power cable - laying and trenching operations



Please be advised that Moray Offshore Windfarm (East) Limited (Moray East) are planning to commence (x3 export routes – wind farm to landfall) cable laying and trenching operations (two separate vessels) circa 27th July 2020


Vessel “NKT Victoria” will be laying the subsea power cables; three export cables between the Moray East offshore wind farm site and the cable landfall (via three separate drilled HDD ducts near Boyndie Bay). Vessel “Havila Phoenix” will be undertaking operations to bury these three subsea power cables below the seabed, via means of remotely operated trenching vehicles. Cable laying is expected to be completed by circa 3rd October 2020. Cable trenching is expected to be ongoing until early November but will be followed by a separate campaign to install remedial protection over the cables on any remaining unburied/unprotected sections. Details on remedial campaign(s) will be provided nearer the time of execution. The above dates include some weather contingency, however the operations may be subject to further extension.

 

Please be aware that by virtue of its mode of operation the NKT Victoria and Havila Phoenix will be Restricted in their Ability to Manoeuvre (RAM) as defined under COLREGs (International Regulations for Preventing Collisions at Sea 1972, Rule 3). Masters of vessels are therefore requested to maintain their vessels and gears at a minimum safe distance from the vessel of 500 metres when it is undertaking work and showing the appropriate shapes and lights in accordance with COLREGs Rule 18. Further updates and Weekly notice of operations can be accessed in the Moray East Website

Diving Campaign near Boyndie Bay



As part of the three export power cable installations for Moray East Offshore Wind Farm, Moray East and their contractor NKT intend to undertake diving works near Boyndie Bay


The above mentioned works includes the preparation works on the HDD duct (offshore) exit, cable installation support works, and post-cable installation grouting and finishing works for the project. Work on the duct and surrounding area will be undertaken by divers connected to diving support vessel “MV C-Fenna” operated by Leask Marine. During diving operations this vessel will be positioned via a four-point anchor mooring spread. Also active during this time will be a crew transfer vessel assisting operations, and transferring personnel will be the MV “C-Spartan”, also operated by Leask Marine. For diving vessel moorings, for the avoidance of any fishing gear or buoyed items posing risk of wire entanglement based on anchor positions, these are marked on the drawing below. Moray East intends to commence diving preparation works on the 6 th of July 2020, for the duct preparation works, and continue diving works on all three cables for installation support, and postinstallation grouting and finishing works. This diving campaign is expected to reach completion circa 18th October 2020. The above dates include some estimated/expected weather delays, however, this activity may be subject to further extension of works.

 

Please be aware that by virtue of its mode of operation the C-Fenna and C-Spartan will be Restricted in their Ability to Manoeuvre (RAM) as defined under COLREGs (International Regulations for Preventing Collisions at Sea 1972, Rule 3). Masters of vessels are therefore requested to maintain their vessels and gears at a minimum safe distance from the vessel of 500 metres when it is undertaking work and showing the appropriate shapes and lights in accordance with COLREGs Rule 18.

Briggs Marine Contractors (on behalf of SHEPD) will be undertaking hydrographic surveys to a number of subsea electricity cables within a 1km wide corridor.


The work will utilise the inshore survey vessel Mersey Guardian and offshore survey vessel Olympic Challenger for the operations.

 

The survey work will be concentrated within the cable route corridor, defined by the points listed in the table below. These coordinates are also specified in the Marine Licences held with Marine Scotland. Survey due to commence on 8th June 2020, and it is expected that this will continue over a planned period of 28 days, weather permitting.

 

Work Description Olympic Challenger will operate between 10m WD contours with Mersey Guardian working in waters shallower than 15m at all landfalls listed as above table.

During operations both vessels will be restricted in their ability to manoeuvre. Both Olympic Challenger and Mersey Guardian may be operating a submerged ROV, up to 300m from vessel.

Survey work undertaken in the Mersey Guardian will be conducted during daylight hours and the vessel will return to port overnight. Should any vessel wish to come within 500m of the survey vessel then direct communication with the Master is required. The vessel will display the appropriate lights / shapes for their operations.

Cable Repair - GTT Segment C



Following cable repair, cable exposed due rocky seabed conditions


Notice to fisheries and seabed users in the Irish Sea:

 

Please be advised that following a recent cable repair to the GTT (Hibernia) Segment ‘C’ between Southport and Dublin, the cable has been deployed as follows:

 

Initial Splice:        53° 48.3613’N    04° 30.1514’W

Standing bight:   53° 48.2208’N    04° 29.4494’W

Final Splice:         53° 48.1279’N    04° 28.2360’W

 

It should be noted that throughout the extent of the cable repair, despite repeated attempts at post lay burial by an ROV, the predominantly very rocky seabed has meant that cable burial and hence protection has not been possible.

 

It should also be noted that at the position of the ‘standing bight’ the cable is standing upright from the seabed at a height of 0.4 metres, with a length over the ground of 2.0 metres.

 

All seabed users are requested not to deploy equipment which engages with the seabed in this area, to avoid snagging of the cable and particularly so, at the standing bight area.

 

In case of any issues, please do not hesitate to contact the GTT Hibernia emergency contact number on: +353 1 867 3600 Option 2

Exposed Export Cable (Beatrice Wind Farm)



During a routine inspection of the export cable EC2, a short section of the cable was found to be partially exposed on the Seabed. This may constitute a hazard to activities such as fishing and anchoring.


A short area (4metres) of partial exposure of Export Cable EC2 is in the vicinity of the mid cable joint at the location where the cable changes direction through 180 degrees.

 

The maximum exposure observed was approx. 50% with no damage or defects observed. The seabed at location was observed to be flat and featureless and mainly consisted of sand and silt. It is requested that mariners avoid activities which are likely to disturb the seabed within a 500m Radius of this location until the exposed cable has been re-buried. A further Notice to Mariners will be issued to confirm the re-burial and safe operation in this area.
