#MARINE NOTICE - The latest Marine Notice (No 61 of 2012) from the Department of Transport, Tourism and Sport (DTTAS) advises that J Murphy & Sons, on behalf of Dublin City Council, will construct a 600mm emergency overflow pipe from Spencer Dock Pump Station through the Liffey quay wall at North Wall Quay/New Wapping Street Junction, Dublin 1.

The work will commence on or around 23 November 2012 and will last approximately two weeks, weather permitting. The location of the works relating to maritime positions is:

Latitude 53° 20’ 49.431 N / Longitude 006° 14’ 08.171 W

The works area will be marked by red buoys. These buoys will be an appropriate distance from the works area and will clearly identify the scaffold when submerged due to high tide. The cantilever beams will project 1.5 metres out from the quay wall.

The only vessel used during the works will be a rescue boat which will be moored at the works location for its duration.

#MARINE NOTICE - The latest Marine Notice from the Department of Transport, Tourism & Sport (DTTAS) reminds all fishing vessel owners, agents, skippers and crew to service their launching and release gear for survival craft on their vessels.

Marine Notice No 60 of 2012 points to the amendments to Chapter III of the SOLAS Convention as outlined in Marine Notice No 37 of 2009 regarding "the operational readiness, maintenance and inspections of launching appliances and on-load release gear for survival craft and rescue boats on board vessels.

"The safety and operational readiness of such equipment fitted on-board fishing vessels is of critical importance and the Department wishes to advise that surveyors from the Marine Survey Office will verify that the requirements for servicing... have been followed as appropriate, during the safety surveys of fishing vessels."

#MARINE WARNING - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises mariners of cable laying operations in the Irish Sea from next week onwards.

The cable laying operations between Wales and Portmarnock Beach in north Co Dublin will commence on Thursday 25 October for approximately 14 days, subject to weather conditions. The works will be undertaken from the C/S Resolute (Call sign V7FF3) supported by the M/V Coastal Discovery (Call sign PBUZ).

Both vessels will display appropriate shapes and lights during the operations, and will keep a listening watch on VHF Channel 16 at all times.

Mariners are particularly advised to note that small craft will also be supporting the main operations vessels in the immediate area of Portmarnock Beach. These craft will have VHF communications, and their movements will be co-ordinated by the main vessels.

In addition, divers will be operating between Portmarnock Beach and the cable laying vessel within the approved corridor for these work and to a maximum distance of 6.5km from the shore.

All vessels, particularly those engaged in fishing, are requested to give all vessels involved in these operations a wide berth.

#WATER SAFETY - The Department of Transport, Tourism and Sport (DTTAS) has published a Marine Notice addressed to all pleasure and recreational craft owners, masters and users to remind the public of the law in relation to being under the influence of alcohol and/or drugs when operating or being on board a vessel in Irish waters.

The 2010 Annual Report of the Marine Casualty Investigation Board (MCIB) highlighted the dangers inherent in excessive alcohol consumption while on board or operating a vessel and emphasised the relevant legislation under the Pleasure Craft (Personal Flotation Devices and Operation) (Safety) Regulations.

While operating a pleasure craft, being towed or on board any floating vessel, it is against the law to be under the influence of alcohol or drugs or any combination of drugs or of drugs and alcohol to such an extent as to be incapable of having proper control of the craft.

It is also against the law to consume alcohol or drugs in circumstances which could affect the safety of others on board or others using Irish waters, or create a disturbance on board or be a nuisance to others using Irish waters.

It is a requirement for the master or owner of a pleasure craft to take all reasonable steps to ensure that persons comply with the regulations.

The Maritime Safety Act 2005 also contains a range of provisions relating to the prohibition on operating a vessel in Irish waters while under the influence of alcohol or drugs, the breaking of which can lead to fines of up to €5,000 and up to three months' imprisonment.

Full details are outlined in Marine Notice No 56 of 2012, a PDF of which is available to read or download HERE.

#MARINE NOTICE - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) draws mariners' attention to the official report on the sinking of the fishing boat Ainmire and its recommendations for safety on board all fishing vessels.

As reported in September last year on Afloat.ie, the report by the Marine Casualty Investigation Board found that a breach in the engine compartment caused the Ainmire to take on water and sink off the coast of Scotland in April 2011.

The report concluded that the failure of a sea water cooling pipe in the engine room was the most likely cause of the flooding, and noted that the pipework had not been renewed during the life of the vessel.

Investigators also noted that the bilge pump was located under the floor plates in the engine room as was this inoperable when the water level rose in the compartment.

Marine Notice No 58 of 2012 - a PDF of which is available to read and download HERE - reminds fishing vessel operators that large sea-water inlets in engine rooms make their boats vulnerable to severe flooding if they fail.

It is recommended that these pipes should be checked for corrosion every year, especially around the welded joint at the hull. Ultrasonic thickness testing of the pipework should also be considered.

Moreover, such pipework can be eroded quickly by stray currents, so electrical equipment should be checked regularly, while the location of bilge pumps in the engine room should be carefully considered

#MARINE WARNING - The Department of Transport, Tourism and Sport (DTTAS) has been advised that subsea rock installation works will shortly commence along a pipeline route from the Corrib Gas Field in Broad Haven Bay off Co Mayo.

Works will commence in the middle of this month (October 2012) and are expected to be completed in 6-10 days. The operation will be carried out by the vessel Tertnes (Call sign PGAN). All vessels in the vicinity are requested to keep clear of the works as these works progress along the pipeline route and to comply with requests from work vessel.

Furthermore, all vessels are requested to monitor and comply with the Radio Navigational Warnings that will be broadcast for the duration of the works. All vessels involved in the operations will be listening on VHF Channel 16 throughout the project. All vessels are required to comply fully with the International Regulations for the Prevention of Collisions at Sea and to manoeuvre their vessels accordingly.

The attention of all is also drawn to Marine Notice No 17 of 2007, which gives general advice in relation to the activities of vessels engaged in survey work for hydrographic, seismic, fishing research and underwater operations.

Full details of co-ordinates for the current works are included in Marine Notice No 57 of 2012, a PDF of which is available to read or download HERE.

#MARINE NOTICE - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) reminds vessel owners and all seafarers of the requirement to service their lifejackets, liferafts and other safety equipment.

All items that form part of a vessel's lifesaving appliances, from SOLAS and MED inflatable liferafts to inflated and rigid inflated rescue boats, inflated boats, inflated life jackets (including immersion suits complying with the requirements for lifejackets), hydrostatic release units (HRUs) and marine evacuation systems are required to be serviced at intervals not exceeding 12 months.

Annual servicing of inflatable liferafts, HRUs and marine escape systems must be carried out by an approved liferaft service station which has been formally appointed by the manufacturer of the approved equipment.

The names and contact details of the currently approved liferaft service stations in Ireland and which have been approved by the Minister for Transport, Tourism and Sport are listed in the appendix on Marine Notice No 53 of 2012, a PDF of which is available to read or download HERE.

Annual servicing of inflated lifejackets (including immersion suits complying with the requirements for lifejackets), inflated boats, inflated and rigid inflated rescue boats must be carried out by a service station which has been formally appointed by the manufacturer of the approved equipment.

Emergency repairs to a vessel’s inflated and rigid inflated rescue boats and inflated boats may be carried out on board that vessel, but permanent repairs shall be effected at a service station ashore as soon as practicable. This notice supersedes Marine Notice No 19 of 2010.

#MARINE WARNING - Seafarers are advised to steer clear of upcoming surface-to-air firing exercises off north Co Dublin, as well as a survey equipment deployment operation in Galway Bay.

Marine Notice No 51 of 2012 outlines that the Defence Forces will be conducting live surface-to-air firing practices at Gormanston Air Defence Range in Co Meath this week on Wednesday 19 and Thursday 20 September from 11am to 3pm each day.

Similar to the exercises conducted this past July, an exclusion zone will be established comprising the land, air and sea areas contained within a radius of three nautical miles centred on Gormanston Aerodrome, with an additional segment centred on the aerodrime and bearing of 015 degree true through Mosney rail station and 106 degrees true through Gormanston rail station seawards for a distance of 10 nautical miles.

The exclusion zone D1 will be enforced by a Naval Service vessel. All mariners in the area are required to remain outside the exclusion zone while the range is active, and are recommended to carefully monitor the radio navigation warnings that will be broadcast throughout the firing period.

Meanwhile, in Galway Bay two Benthic Lander devices will be deployed between 24 and 26 September, to be recovered between 29 and 31 September.

The national research vessel R/V Celtic Voyager (call sign EIQN) - which will host the Science@Sea marine science training scheme this coming November - will carry out the deployment of the 2-3-metre high devices that will monitor sediment movement, current speed and direction, and wave motion at depth.

All vessels, particularly those engaged in fishing, are requested to give the vessel and wide berth of at least 500 metres and keep a sharp lookout.

Details of relevant co-ordinated are included in Marine Notice No 52 of 2012, a PDF of which is available to read or download HERE.

#MARINE WARNING - The latest Marine Notices from the Department of Transport, Tourism and Sport (DTTAS) advise mariners to keep a look-out for rock placement off north Co Dublin and buoy placements off Co Mayo and Co Clare.

Operations were due to commence on Saturday 8 September at North Beach in Rush, Co Dublin for the placement of rocks offshore and in the Irish Sea for a period of 10-12 days weather permitting.

The works are being undertaken by DPFPV Tideway Rollingstone (call sign PHYR) and DPFPV Stornes (call sign PCKX) at various locations detailed in Marine Notice No 49 of 2012, a PDF of which is available to read or download HERE.

These vessels are operating on a 24-hour basis and will display appropriate days shapes and lights. They are also transmitting an AIS signal and will keep a listening watch on VHF Channel 16 for the duration of the works, which involve the deployment of survey ROVs and fall pipe that will restrict the vessels' movements. All mariners are instructed to give a wide berth.

Meanwhile off the west coast, ESB International has deployed two Waveroder buoys as positions near Achill Island in Co Mayo and Doonbeg in Co Clare.

The Achill buoy will be operational for a minumum of three months from now, while the Killard buoy will be operational for a minimum of 10 months having been recently relocated. Both are spherical and yellow in colour. All vessels are requested to give the buoys a wide berth.

Full details of their positions are included in Marine Notice No 50 of 2012, a PDF of which is available to read or download HERE.

#MARINE WARNING - In its latest Marine Notice to mariners in the Irish Sea, the Department of Transport, Tourism and Sport (DTTAS) advises of cable repairs being carried out east of Kilmore Quay in Co Wexford.

Operations commenced yesterday 6 September and will continue till approximately next Thursday 13 September, subject to the weather. The works will be undertaken by C/S Peter Faber (call sign FLEV).

During repairs the vessel will be links to the seabed by the cable and will have poor manoeuvrability. This will be signalled with shapes and/or lights as required. The vessel will also broadcast regular safety messages to give details of activity and position.

All vessens in the area, especially those engaged in fishing, are requested to give a wide berth, and not to pass between the repair vessel and the shore.
