The North Irish Sea Array (NISA) has rescheduled a previously planned geotechnical site investigation campaign on the proposed offshore wind farm area off the coast of north Co Dublin, Meath and Louth.

This campaign will involve the deployment of seabed borehole drilling and cone penetration test (CPT) equipment for continuous sampling and is expected to be completed between today, Friday 4 November and Thursday 8 December, subject to weather and operational constraints.

It will be confined to the proposed NISA offshore wind farm area, which forms an irregular shape spanning 32km north-south and 14km east-west at its widest point. At its closest location, near Rush in Co Dublin, the survey site is 7.4km from the coastline.

The survey will be conducted on a 24-hour basis by the Fugro Synergy survey vessel (callsign C6XR3).

As this vessel will be restricted in its ability to manoeuvre when surveying, due to the deployment of the seabed sampling equipment for the duration of the survey activities, other vessels are kindly requested to keep a wide berth.

An onboard fisheries liaison officer will be available to discuss operations throughout the duration of the survey campaign.

The vessel will display appropriate lights and signals. Mariners are also advised to keep continuous watch on VHF Channel 16 when navigating the area.

Coordinates and a map of the survey area as well as contact details can be found in Marine Notice No 74 of 2022, attached below.

The annual Irish Groundfish Survey (IGFS) for 2022 will be carried out by the Marine Institute off the North West, West and South Coasts of Ireland from next Monday 31 October to Friday 16 December.

The IGFS is a demersal trawl survey consisting of approximately 170 fishing hauls of 30-minute duration each in ICES areas VIa, VIIb, VIIg and VIIj.

Fishing will take place within a two-nautical-mile radius of the positions indicated in the appendices to Marine Notice No 73 of 2022, which can be downloaded below.

The survey will be conducted by the RV Celtic Explorer (callsign EIGB) which will display appropriate lights and signals. The vessel will be towing a high headline GOV 36/47 demersal trawl during fishing operations.

The Marine Institute requests that commercial fishing and other marine operators keep a two-nautical-mile area around the tow mid-points clear of any gear or apparatus during the survey period outlined above.

Further details can be found in the Marine Notice attached below.

The Department of Transport says it is advised that the Air Corps will conduct air-to-ground air firing exercises in the Gormanston D1 Air Range in Co Meath next Thursday 27 and Friday 28 October.

Live firing will take place on the Thursday between noon and 9pm and on the Friday between 11am and 4pm IST.

Marine Notice No 72 of 2022 says an Activation Notice (Danger Area D1 – Gormanston) will be issued.

The officer in charge of firing on each day will be fully briefed regarding communication between the firing point and the Air Traffic Control Centre at Dublin Airport. The Naval Service or Air Corps RHIB will enforce an exclusion zone.

Contact details are available in Marine Notice No 72 of 2022, attached below.

Trial operations of remotely piloted uncrewed surface vessels (USVs) are planned to take place in the Dundalk Bay area from this week until mid November.

Subject to weather and operational constraints, the operations will run for a period of four weeks from Thursday 20 October.

The XO-450-type USVs from Greenore-based Xocean will be engaged in survey activities for the proposed Oriel Wind Farm in the Irish Sea some 22km off the coast of Dundalk in Co Louth.

This is a non-invasive survey, Xocean says, and no contact with the seabed or any other infrastructure is planned during survey operations.

The USVs will send real-time images and situational awareness data over satellite to a team of operators keeping watch and controlling the vessel remotely 24/7.

Although the vessels are uncrewed, they are constantly monitored and controlled, and piloted remotely using 360-degree cameras and other navigational aids.

Each USV is equipped with AIS, navigation lights and a sound signal, an active radar reflector and a yellow-painted superstructure to make it conspicuous to other marine traffic.

All other vessels operating within the affected area are requested to avoid contact with any USV and be aware of the operational area during this period. A Radio Navigation Warning will be in place during operations.

Contact details, relevant coordinates and a map of the survey area are included in Marine Notice No 71 of 2022, attached below.

The Department of Transport advises that a new online ship radio licence and EPIRB registration system is being implemented as of Monday 17 October.

This system replaces the paper form and email application processes and is be available at the online portal for the Irish Maritime Radio Licence System (IMRAD).

A ship radio licence is required under national and international legislation to certify that a vessel may operate approved radio communication equipment on specific maritime radio frequency bands and is also necessary for the assignment and recording of unique vessel radio communication maritime identifiers such as callsigns and MMSI numbers.

The registration of EPIRBs (Emergency Position Indicating Radio Beacon) carried on board Irish vessels is also mandatory.

These licensing and registration processes are coordinated internationally to protect maritime safety-related communications worldwide and to facilitate and support distress, safety and search-and-rescue operations.

This new online system provides users with a convenient means to fulfil these licensing and registration obligations.

In addition to the regulatory requirements, the effectiveness of maritime radio equipment including EPIRBs for search-and-rescue communications depends upon correct identification, encoding, programming and registration of devices.

The Irish Coast Guard relies upon the information contained in this system for search-and-rescue operations to quickly identify vessels and to obtain emergency contact information. This information is also used to quickly resolve inadvertent distress alert activations so that search-and-rescue resources are deployed effectively and not to false alerts.

It is therefore essential that up-to-date and accurate vessel and contact details are recorded in this system. The information is also provided to the ITU international MARS database system for notification to other maritime administrations worldwide.

For full details see Marine Notice No 70 of 2022, attached below.

Update: the survey has been rescheduled for 4 November-8 December 2022 and Marine Notice No 69 of 2022 withdrawn.

Following this past week’s deployment of metocean instrumentation, the North Irish Sea Array (NISA) intends to undertake a geotechnical site investigation campaign on the proposed offshore wind farm area off the coast of north Co Dublin, Meath and Louth.

This campaign will involve the deployment of seabed borehole drilling and cone penetration test (CPT) equipment for continuous sampling and is expected to be completed between next Monday 17 October and Sunday 20 November, subject to weather and operational constraints.

It will be confined to the proposed NISA area, which forms an irregular shape spanning 32km north-south and 14km east-west at its widest point. At its closest location, near Rush in Co Dublin, the survey site is 7.4km from the coastline.

The survey will be conducted on a 24-hour basis by the Fugro Synergy survey vessel (callsign C6XR3).

As this vessel will be restricted in its ability to manoeuvre when surveying, due to the deployment of the seabed sampling equipment for the duration of the survey activities, other vessels are kindly requested to keep a wide berth.

An onboard fisheries liaison officer will be available to discuss operations throughout the duration of the survey campaign.

The vessel will display appropriate lights and signals. Mariners are also advised to keep continuous watch on VHF Channel 16 when navigating the area.

Coordinates and a map of the survey area as well as contact details can be found in Marine Notice No 69 of 2022, attached below.

Marine data company Partrac is planning a new deployment of metocean instrumentation for the North Irish Sea Array (NISA) over a three-day period from Monday 10 October.

These will replace the instruments deployed in January this year, as previously reported on Afloat.ie, on a schedule subject to weather and operational constraints.

The survey campaign will be undertaken within the proposed NISA offshore wind farm array area. This forms an irregular, approximately rectangular shape, spanning 31km north-south and 14km east-west at its widest point. At its closest location, near Rush in Co Dublin, the array area is approximately 7.4km from the coastline.

Deployments will be carried out from the AMS Retriever (callsign MEHI8) which will be restricted in its ability to manoeuvre. All other vessels are requested to leave a wide berth during the deployment operations. Radio transmissions will be conducted with other seafarers to notify them of the operations.

Coordinates of the deployments as well as characteristics of the metocean buoys and contact details are included in Marine Notice No 68 of 2022, attached below.

Various works are taking place this month to facilitate the development of the Braymore Wind Park in the north Irish Sea.

A geophysical survey was scheduled to start last week to be completed by early November, subject to weather and operational constraints, to provide site investigation information for the proposed Braymore Wind Turbine Generator (WTG) Array.

The Braymore WTG Array area is located some 18km from Dunany Point in Co Louth at its most northerly point and Braymore Point in Co Dublin at its most southerly.

Operations will be conducted on a 24-hour basis by the Roman Rebel (callsign 2ICA5) and on a 12-hour basis by the Lady Kathleen (Callsign EIXT2). The vessels will display appropriate lights and signals.

Due to the deployment of towed survey equipment, the survey vessels will be restricted in their ability to manoeuvre when surveying.

All other vessels operating in their vicinity are requested to keep their distance and pass at minimum speed to reduce vessel wash. Mariners are advised to keep continuous watch on VHF radio channel 16 when navigating the survey area.

Coordinates and a map of the survey area, as well as contact details, can be found in Marine Notice No 66 of 2022, attached below.

Meanwhile, three surface buoys, three guard buoys and one sub-surface mooring are to be deployed at the wind farm site for a metocean and passive acoustic monitoring (PAM) survey campaign.

The deployments are expected to be completed over a two-day period from this Wednesday 5 October, subject to weather and operational constraints. The devices will remain deployed for a period of 12 months.

These operations will be conducted by the Damen Shoalbuster 2409 versatile multi-purpose and shallow draft tug AMS Retriever (callsign MEHI8).

During operations, the vessel will be restricted in its ability to manoeuvre and all other vessels are requested to leave a wide berth during the deployment operations. Radio transmissions will be conducted with other seafarers to notify them of the operations.

Characteristics of the buoys, as well as contact details, coordinates and a map of the deployment area, are included in Marine Notice No 67 of 2022 as attached below.

Operators of the North Irish Sea Array (NISA) offshore wind farm will shortly undertake a subtidal benthic ecology survey campaign on its proposed export cable route area, off the coast of north Co Dublin and Co Meath.

Similar to the campaign this past summer, it will involve the deployment of benthic grab, water quality sonde and drop-down video equipment from a survey vessel within the bounds of the proposed NISA Export Cable Route area.

It is expected to be completed between next Wednesday 28 September 2022 and Wednesday 5 October, subject to weather and operational constraints.

As with the concurrent geophysical survey, the campaign will be confined to the proposed NISA Export Cable Route area. This area forms an irregular shape spanning 11km north-south and 18km east-west at its widest point. The survey area has two landfall areas close to Balbriggan in north Co Dublin.

The benthic survey campaign will be conducted by the survey vessel Husky (callsign 2EQI7). An onboard fisheries liaison officer will be available to discuss operations throughout the duration of the survey campaign.

The survey vessel will display appropriate lights and signals. All other vessels operating within this area are requested to keep a wide berth and pass at minimum speed to reduce vessel wash. Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

Contact details, coordinates and a map of the survey area are included in Marine Notice No 64 of 2022, attached below.

Operators of the North Irish Sea Array (NISA) offshore wind farm are undertaking a geophysical survey campaign on its proposed export cable route area, off the coast of north Co Dublin and Co Meath.

This campaign is expected to run from next Monday 12 September to continue until Wednesday 12 October, subject to weather and operational constraints.

The survey campaign will be confined to the proposed NISA Export Cable Route area. This area forms an irregular shape spanning 11km north-south and 18km east-west at its widest point. The survey area has two landfall areas close to Balbriggan and surveys will proceed as shallow as around three metres of water depth.

The survey will be conducted by the vessels Geo Focus (callsign PCOS) and Ros Áine (callsign EIZG5) in depths of greater than and less than 10m respectively, both working on a 24/7 basis.

The survey will utilise multibeam echosounders, sub-bottom profilers, side-scan sonar, magnetometer, both hull-mounted and towed. Typically, the towed cable lengths will be about four times the water depth while acquiring survey data.

Both vessels will display appropriate lights and signals. Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

As the survey vessels will be restricted in their ability to manoeuvre when surveying, due to the deployment of the towed survey equipment, all other vessels operating within this area are requested to keep a wide berth and pass at minimum speed to reduce vessel wash.

Contact details, coordinates and a map of the survey area are included in Marine Notice No 63 of 2022 amended, attached below.
