A new Marine Notice from the Department of Transport, Tourism and Sport reiterates the requirements for lifejackets on pleasure craft and personal water craft.

Superseding a previous notice from spring 2016, the new document explains personal flotation devices or PFDs (both lifejackets and buoyancy aids), the relevant regulations and legal requirements, and instructions for their safe use on the water.

Full details can be found in Marine Notice No 32 of 2019, a PDF of which is available to read or download HERE.

Geophysical surveys are being undertaken in the Irish Sea in outer Dundalk Bay from this week.

The work is required to provide bathymetric and subsurface information for the development of the Oriel Wind Farm project.

Survey work was expected to start yesterday, Tuesday 20 August, with a view to completion by Monday 30 September, though these dates are weather dependent.

The surveys will be completed using the AMS Retriever (Callsign MEHI8), a versatile multi-purpose, shallow draft tug.

This vessel is towing survey equipment up to 100 metres astern and will be restricted in its ability to manoeuvre.

Other vessels are requested to leave a wide berth. The AMS Retriever will be operating from approximately 6am to 9pm during survey works.

Details of co-ordinates of the survey area are included in Marine Notice No 29 of 2019, a PDF of which is available to read or download HERE.

Site investigation works are to be carried out at Rossaveal Fishery Harbour Centre in Co Galway from mid August.

The works will comprise drilling multiple boreholes at the locations detailed in Marine Notice No 28 of 2019, subject to minor variations.

The drill holes will be in navigable waters off Cashla Bay. In keeping with previous Marine Notices with respect to marine construction works, the areas where the drill rig is to be set up must be kept clear of all obstructions including static fishing gear.

A jack-up barge will be moved to the various borehole locations by a tugboat, and will remain on site overnight during the proposed works. All appropriate lights will be displayed by the barge at night. Radio warnings will be transmitted on VHF Channel 16 throughout the works.

Work is expected to commence in mid-August 2019 subject to the contractor’s precise mobilisation timescales, and last for around four weeks, weather permitting.

A seabed debris clearance, environmental baseline and habitat assessment site survey will take place in licence SEL 1/11 (Barryroe) from later this month.

Barryroe is located in the North Celtic Sea, some 50 kilometres south of the Port of Cork.

The project is scheduled to commence in mid-August 2019 with the survey vessel Kommandor (callsign MCJO2) anticipated to be working on location for 16 days, excluding transit and any weather delays

Survey operations will be conducted on a 24-hour basis in different phases to include towed and non-towed operations. A fisheries liaison Officer will be on board for the duration of the survey.

Throughout the survey operations, the vessel will be displaying appropriate shapes and lights to indicate that the survey vessel is restricted in its ability to manoeuvre.

All vessels are requested to give this operation a wide berth. A listening watch will be maintained on VHF Channel 16, and the vessel will actively transmit an AIS signal.

Full details of the site survey co-ordinates are included in Marine Notice No 27 of 2019, a PDF of which is available to read or download HERE.

Marine Notice No 25 of 2019 from the Department of Transport, Tourism and Sport advises that there will be a deployment of ADCP current meters on the sea floor in Castletownbere, Co Cork from tomorrow, Thursday 25 July.

Current meters will be mounted in a stainless-steel frame at two locations: Lat 51°38'33.06”N, Long 009°54'42.00"W and Lat 51°38'33.00”N, Long 009°53'43.68”W.

The stainless-steel frame will be deployed from vessel An tOileanach (Callsign EI5930) for 14 days from tomorrow, subject to weather.

Surface spar-style buoys will be used to mark locations. Buoys will be a 700mm diameter yellow buoy of height approximately 1m above the water line.

The buoys will be fitted with a flashing LED light with a range of 2-3 nautical miles. The light will be set to flash 3 times every 10 seconds (duration of flash 0.3 seconds).

The main lay installation works for the Rockabill Subsea Cable will take place from tomorrow, Saturday 20 July, to Sunday 1 September.

Using the vessel CS Teliri (callsign IBBT), the Rockabill cable system will be conducted from north of Lambay Island across the Irish Sea to Southport in England.

The cable itself is armoured and has an OD of 38mm. The cable ship will firstly clear the route of seabed debris with a grapnel before installing the cable.

During installation operations, the vessel will be moving slowly along the route while towing a sea plough to bury the cable into the seabed. During these works the vessel will have restricted manoeuvrability as it completes the work scope.

Deployed guard vessels will monitor the exposed areas of cable at crossing locations while burial progresses.

Ships are asked to avoid using anchors, bottom-trawl fishing and other seabed gear within half a mile of this cable route, and to maintain a safe distance from the cable ship during installation operations and that static gear be relocated from the route prior to commencement of operations.

Vessels are requested to pass at a safe speed and distance and fishing vessels are advised to remain a safe distance from the areas identified. Guard vessels will be deployed at certain cable crossing points to aid in monitoring the exposed areas and will advise of safe distances locally. The vessels will monitor VHF Channel 16 at all times.

The location co-ordinates of the operation are as included in Marine Notice No 24 of 2019, a PDF of which is available to read or download HERE.

TechWorks Marine Ltd is deploying trawl-resistant bottom mounted Acoustic Doppler Current Profiler (ADCP) frames in Waterford Harbour this week.

It is anticipated that the ADCPs will be deployed between today, Monday 8 July, and this Friday 12 July, depending on the weather. If the deployment is delayed due to the weather, it will be carried out on the next viable tide and weather window. Update: the ADCPs will now be deployed on or after Thursday 18 July.

The frames will be deployed from the vessel James (callsign EITT2). The frames will be on the seafloor for a minimum period of one calendar month and a maximum period of two months (weather permitting).

The ADCPs will be measuring currents through the water column at each location over the deployment. This data will be used to validate a hydrodynamic model of the area being developed for Irish Water.

Each frame will have one ADCP sensor, an acoustic pinger, an acoustic release and a rigid recovery buoy.

The frames are approximately 1m2 and will remain on the seafloor for a period of up to 30 days, after which the frame will be retrieved using the acoustic release and recovery buoy.

There will be no surface marker during the extent of deployment so vessel traffic will not need to avoid the area but should be aware of its presence.

Details of the relevant co-ordinates are included in Marine Notice No 22 of 2019, a PDF of which is available to read or download HERE.

Meanwhile, planned cable survey works on the EirGrid East West Interconnector are being carried out by the vessel Deep Helder (callsign PBYU) until this Thursday 11 July. During this survey, the vessel will be deploying underwater survey equipment along a thin 50m corridor.

Fishermen are advised not to leave any static fishing equipment in the vicinity of the survey route (250 metres) and keep a safe distance of at least one nautical mile from the survey vessels that will be operating with towed equipment and will have restricted manoeuvrability.

In addition, the survey vessel Ping will carry out operations in the near-shore waters off Rush, Co Dublin from next Monday 15 July. Near-shore survey operations will take place between beach HW mark and the 10m water depth contour.

Details of co-ordinates and survey contacts are included in Marine Notice No 21 of 2019, a PDF of which is available to read or download HERE.

Planned works on the Portrane Pre-Lay Shore End installation for the Rockabill Subsea Cable are being carried out from the coast of Portrane, Co Dublin.

Scheduled to start yesterday. Monday 1 July, they will continue to next Wednesday 10 July. During this first Pre-lay Shore End phase of the project, the cable will be installed and buried in the Irish Sea by the utility vessel Roxane Z (Callsign FIRJ).

The vessel will monitor VHF Channel 16 at all times. All vessels, particularly those engaged in fishing, are requested to give the Roxane Z a wide berth and keep a sharp lookout in the relevant areas.

Details and co-ordinates of the work area are included in Marine Notice No 20 of 2019, a PDF of which is available to read or download HERE.

Another recent Marine Notice includes an updated schedule of examinations for the Certificate of Competency for Deck Officers, Marine Engineer Officers, Skippers and Second Hands, commencing Monday 2 September this year.

A series of ecological surveys will take place in the Irish Sea off the Dublin and Wicklow coast between now and May next year to provide data on seabirds and marine mammal species to inform the development of the Dublin Array Wind Farm.

The survey dates are weather dependent but will comprise a survey in each calendar month until May 2020, commencing tomorrow (Monday 24 June), with additional monthly surveys this August and September.

The location of the surveys will be off the Dublin and Wicklow coast in the vicinity of the Kish and Bray Banks. Surveys will be undertaken in daylight hours and each will usually be completed over a period of two days.

For the initial survey, the work vessel will not be towing survey equipment. During subsequent surveys the vessels may be towing a hydrophone up to 100m astern and will be restricted in their ability to manoeuvre. Vessels are requested to leave a wide berth.

Details of co-ordinates of the survey areas, and relevant work vessels, are included in Marine Notice No 18 of 2019, a PDF of which is available to read or download HERE.
