Green Rebel Marine in Crosshaven is set to undertake a geophysical survey operation in the Celtic Sea from next week.

The survey from next Wednesday 26 May to 23 June, weather permitting, will be conducted by the Roman Rebel (callsign 2ICA5) using hull-mounted multibeam and sub-bottom profiling systems.

In addition, the vessel will be towing side-scan sonars and magnetometers using dedicated winches at cable lengths dictated by the water depth. Typically, the cable lengths will be about four times the water depth while acquiring data.

The Roman Rebel will display appropriate lights and signals and all survey operations will be conducted 24 hours a day, continuous over day and night.

Full details of coordinates of the survey areas are included in Marine Notice No 32 of 2021, which can be downloaded below.

A number of acoustic listening stations have been depleted at Tory Island to detect the presence tagged marine wildlife as part of an EU INTERREG research project.

The 12 ALS units have been placed in the waters around the island off the coast of North Donegal.

Most are in depths of more than 30 metres and are fitted with acoustic releases, without the need for lines to surface.

A small number of inshore arrays are attached to 16-inch orange hard floats marked ‘SeaMonitor’ with a corresponding ID. If accidentally hauled or otherwise found out of place, they also contain contact details for retrieval by the project coordinators.

Further details, including coordinate of the ALS locations, can be found in Marine Notice No 31 of 2021 which is available to download below.

The latest Marine Notice for works on the Codling Wind Park project advises of the deployment of metocean equipment between today, Tuesday 11 and Friday 28 May.

One wave buoy and one acoustic Doppler current profiler (ADCP) frame will be deployed and used to characterise the wind park area at the Codling Bank some 13km off Co Wicklow.

These works are being carried out on a 12-hour basis by the AMS Retriever (callsign MEHI8) which will display all appropriate shapes and lights.

The vessel will be restricted in ability to manoeuvre so all other vessels in the are are requested to keep a their distance and pass at minimum speed to reduce wash.

Further details, including relevant coordinates, are included in Marine Notice No 30 of 2021 which can be downloaded below.

More works are scheduled for the Codling Wind Park project, with the deployment of two lidar buoys to characterise the wind park area from this week.

Weather permitting, the Voe Vanguard (callsign MBEN9) will deploy the buoys in the Irish Sea off Co Wicklow between tomorrow, Tuesday 27 April and Friday 14 May.

Deployment operations will be conducted on a 12-hour basis. The Voe Vanguard will be restricted in ability to manoeuvre, so all vessels operating within its work area are requested to keep their distance, maintaining a safety zone around the survey vessel and pass at minimum speed to reduce vessel wash.

Throughout survey operations, the Voe Vanguard will be displaying appropriate lights and shapes. The lantern on the buoys will give out five yellow flashes every 20 seconds, visible for up to three nautical miles.

Further details including the relevant coordinates are included in Marine Notice No 29 of 2021, which is available to download below.

The latest notice follows previous advisories for geophysical surveys and geotechnical surveys over the next number of weeks for the wind farm scheme at the Codling Bank.

Following the recent notice of geophysical surveys for the Codling Wind Park comes news of a series of geotechnical surveys in the Irish Sea off Wicklow for the project set to commence tomorrow, Monday 26 April.

Works to characterise the wind park area will be conducted until Saturday 26 June, weather permitting, from the LB Jill (callsign WDH 6208) on a 24-hour basis. The vessel will display appropriate lights and shapes.

As the LB Jill will be restricted in ability to manoeuvre, all vessels operating within the work area are requested to keep their distance, maintaining a safety zone around the geotechnical investigation vessel, and pass at minimum speed to reduce vessel wash.

Further details including coordinates for the survey works are included in Marine Notice No 28 of 2021, which can be downloaded below.

Green Rebel Marine will conduct a geophysical survey campaign over 15 days between this Monday 26 April and Friday 4 June, weather depending.

The works, which will involve the use of multibeam echo-sounder and sub-bottom profiling systems, will take place at a number of locations off the West Coast

The survey will be conducted by the Roman Rebel (callsign 2ICA5), a semi-SWATH catamaran with all equipment hull-mounted which operates out of Green Rebel Marine’s base at Crosshaven Boatyard. The Roman Rebel will conduct 24-hour operations.

Further details including coordinates of the work areas are included in Marine Notice No 27 of 2021, which can be downloaded below.

The Department of Transport has been advised of a route clearance and pre-lay grapnel run, on behalf of SubCom LLC, across the pathway of the Grace Hopper subsea fibre optic cable system route in the Irish EEZ.

Operations were set to begin today, Saturday 24 April and will continue to Friday 30 July, weather depending, and will be conducted by the Nautilus (callsign EAOL). The vessel will be listening to VHF Channel 16 but can be set to any other as required.

Nautilus will be towing stern-deployed equipment and will be restricted in manoeuvrability. All vessels operating within this area are requested to keep their distance, and pass at minimum speed to reduce vessel wash.

Details of coordinates of the works over the next three months are include in Marine Notice No 26 of 2021, which can be downloaded below.

The latest Marine Notice from the Department of Transport advises that Kinsale Energy will undertake diving operations at the Kinsale and Seven Heads Gas Fields for decommissioning on and around the subsea infrastructure.

These works are due to commence on or around Monday 10 May and are estimated to last 25 days, weather depending.

Diver operations will be conducted by the dive support vessel Deep Discoverer (callsign C6EB7) which will be listening on VHF Channel 13, and will take place in the locations listed in Marine Notice No 25 of 2021, which can be downloaded below.

The Department of Transport advises that a survey will take place at several offshore reefs and sandbanks off the North West Coast from next Friday 23 April to Tuesday 4 May.

Survey works with marine robots in support of the EU Horizon 2020 research and innovation programme will take place within a three-nautical-mile radius of six shipwrecks, the coordinates of which are included in Marine Notice No 24 of 2021 which can be downloaded below.

The survey will be conducted from the RV Celtic Explorer (callsign EIGB) which will conduct acoustic surveying during the night using its hull mounted multibeam, with remotely operated vehicle (ROV) sampling during daylight hours.

In addition, the vessel will be used as a platform to deploy a range of unmanned underwater vehicles (UUVs) and a series of six small (1.2m3) pyramidal landers, referred to as baited remote underwater video (BRUV).

At all times, the RV Celtic Explorer will display appropriate lights and signals.

The Department of Transport has been advised that Codling Wind Park Limited intend to conduct a series of geophysical surveys in the Irish Sea off Dublin and Wicklow from Wednesday 14 April to Wednesday 26 May, weather permitting.

This work is intended to provide options for export cable routes to possible landfall options in the areas of Poolbeg, Dun Laoghaire, Greystones and Wicklow.

A total of two vessels will be working on the project. Arctic Ocean (callsign OZGP2) will undertake geophysical operations to characterise the export cable sites (weather permitting). Survey operations will be conducted on a 24-hour basis.

Meanwhile, Faraday (callsign MJZX5) will undertake geophysical operations (weather permitting). Survey operations will be conducted on a 12-hour basis.

Throughout survey operations, the vessels will be displaying the appropriate lights and shapes. As both vessels will be towing survey equipment, they will also require large turning circles and will be restricted in their ability to manoeuvre.

All vessels operating within the work area are requested to keep their distance, maintaining at least the 500m safety zone around the survey vessel and pass at minimum speed to reduce vessel wash.

Further details including coordinated and contacts are included in Marine Notice No 21 of 2021, a PDF of which can be downloaded below.
