#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that marine scientists from the Dublin Institute of Advanced Studies (DIAS) are deploying a tsunameter close to the new location of the M4 weather buoy off the Donegal coast.

In addition to the tsunameter, they will also deploy a sub-surface buoy with an acoustic Doppler current profiler (ADCP) mounted on it, as well as pressure sensors clamped to a moored string to measure pressure variations at depth. This system will be deployed in proximity to the tsunameter location but not too close to avoid tangling.

The tsunameter and system used for the ADCP and the pressure string sensors is scheduled to be be deployed imminently from the RV Celtic Voyager (Callsign: EIQN) at latitude 54°59.892 N, longitude 009°58.14 W, at a depth of 119m adjacent to M4 weather buoy.

As this is sensitive scientific equipment, it is requested that fisherman and marine operators engaged in such activities as bottom trawling or laying of static gear avoid the locations concerned to avoid damaging the equipment or damaging fishing gear.

#Fishing - The latest Marine Notice from the Department of Transport, Tourism and Sport reminds fishing vessel operators to monitor their bilge spaces prior, during and after voyages.

It is also essential that bilge alarms are tested regularly, to determine that both the audible and visible alarms are working.

In addition, it is good practice to regularly inspect bilge suction strainers to ensure they are clean and ready for use.

The notice is prompted by the recommendation made in last year's report by the Marine Casualty Investigation Board into the sinking of the FV Napier off the Saltee Islands on 30 January 2014.

As previously reported on Afloat.ie, the Kilmore Quay lifeboat launched to the rescue of two fishermen on board the small lobster boat as it sank off the Co Wexford islands.

The official MCIB report into the incident was unable to determine the exact cause of water flooding the boat's bilge and engine area as it was not recovered from the sea bed, though it is presumed to be a serious failure of the seawater cooling system.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises of the of the dredging of soft material and disposal at sea, drilling and blasting and removal of bedrock, construction of breakwater and revetment and other associated works at Rossaveal Fishery Harbour Centre.

The works by Cronin Millar Consulting Engineers at the Galway Bay fishing harbour will commence on tomorrow Monday 22 August and continue till January 2017.

The first phase of the works, commencing tomorrow, will comprise the construction of a temporary causeway on the foreshore within the dredge site to facilitate excavation of seabed and disposal at a licensed on-shore site.

The second phase of the works, will commence in the coming weeks and will involve a jack-up barge, floating barge, safety boat, personnel boat, split barge and work boats. This will be advised under a second marine notice.

Maps and co-ordinates of the work areas are detailed in Marine Notice No 34 of 2016, a PDF of which is available to read or download HERE.

Other recent Marine Notices cover outfall pipeline remedial works ongoing at the Corrib gas field, and information on the carriage of inflatable life rafts on small fishing vessels under 15m.

#MarineNotice - Shell E&P Ireland were scheduled to commence flowline installation works between two existing subsea wells at the Corrib gas field this week.

This work will be followed by placement of rock protection along the length of the exposed flowline between the two wells.

There may also be some additional rock placement along the pipeline corridor from the offshore field to the landfall at Broadhaven Bay.

The works, due to commence during this last week of July, are expected run for 30 to 40 days.

The first phase of works will all take place within the 500m Safety Zone surrounding the wells P2 and P5, and along the corridor between P2 and P5.

Carried out by the Skandi Neptune (callsign 2HMG8), the work involves the lay of a new flowline between the two wells followed by connection at each end and pressure testing.

Final seabed connections will be completed on the existing seabed control umbilical followed by the commissioning of the P2 well control system.

This work is expected to be completed by mid August, after whic the Nordnes (callsign PHOG) will commence the second-phase rock placements.

The guard vessel Glomar Arctic (callsign H09083) will be on location in the Corrib Field for the duration of the project. Radio warnings will be given to all marine traffic in the
immediate area. All the vessels will be listening on VHF Channel 16 throughout the project.

Details of co-ordinates of the relevant work areas are included in Marine Notice No 29 of 2016, a PDF of which is available to read or download HERE.

Meanwhile, TechWorks Marine were scheduled to deploy two temporary buoys in the Shannon Estuary on Friday 29 July.

The buoys are required for the placement of turbidity sensors before and during a dredge campaign, and will be in place for the next four weeks.

These data buoys, deployed on a single point mooring, are 1.2m wide, are yellow in colour and have a yellow navigation light with a 2nm range, with five flashes every 20 seconds.

Co-ordinates are included in Marine Notice No 30 of 2016, a PDF of which is available to read or download HERE.
