The multifunctional vessel, built to operate in difficult sea conditions, is being stocked with additional equipment ahead of a major search of the crash site off Blacksod in Co Mayo scheduled for tomorrow (Sunday 19 March) with the forecast of improved weather conditions.
TheJournal.ie reports that what’s believed to be wreckage from the Sikorsky S92 helicopter has been found on the island of Black Rock, west of Blacksod, but there are no signs of a crash having occurred at that site.
Three crew – chief pilot Mark Duffy and winch men Paul Ormsby and Ciarán Smith — remain missing after the incident in the early hours of Tuesday (14 March) as the Dublin-based Irish Coast Guard helicopter provided top cover for a medevac.
Meanwhile, it emerged on Thursday (16 March) that Rescue 116 was tasked to the scene on Tuesday after the Irish Air Corps was unable to provide assistance due to reduced capacity, according to The Irish Times.
#DryDocking - ILV Granuaile (2000/2,625grt) departed Cork Harbour and is bound for Rosslare Harbour this evening having undergone dry-docking, writes Jehan Ashmore.
Among the work carried out on the Commissioners of Irish Lights tender at Cork Dockyard were some service work done on thrusters and re-chroming of crane rams.
The Dutch Damen Group which built the vessel at their Romanian yard in Galati, had also undergone in Cork Dockyard last year a major '15 Special Survey & Dry-Docking'. The Rushbrooke yard fought off stiff competition for the EU tender as part of a €650,000 project to enable continued operation to Lloyds +100A1 Classification.
ILV Granuaile yesterday morning departed a river-berth for sea-trials. This involved the 79m long lighthouse tender pass Cobh to where a pair of UK registered factory trawlers berthed following detention off the Blaskets by the Naval Service.
She then headed beyond Roches Point Lighthouse, marking the entrance to Cork Harbour from where a circuit was made at sea before returning to the dockyard.
The trawlers Wiron 5 and Wiron 6 are 55m in length and have a Dutch crew of 14 each. They were detained for alleged fishery infringements by the OPV L.E. Samuel Beckett (P61) which escorted the vessels to Cobh and then she headed upriver to berth in Cork City quays.
#UKMetOfficeBuoy – The Commissioners of Irish Lights tender ILV Granuaile (2000/2,625grt) successfully deployed a KI buoy recently for the UK's Met Office.
The positioning of the deep-water mooring buoy took place some 250 miles west of the French port of Brest in Brittany.
The Romanian built / Dutch outfitted Granuaile, has previously carried out maintenance visits on the K1 buoy, this was the first time a completely new set of moorings was deployed.
The extreme length of the cable introduced new and potentially hazardous challenges to the ships personnel.
In total almost 2,500 meters of a mixture of rope and chain moorings were deployed in depths of 1,500 m.
The successful deployment of the deep-water mooring proved how versatile and innovative the Granuaile is and that of her crew when faced with tough new offshore challenges.
#LighthouseTender- ILV Granuaile the aids to navigation tender is carrying out another trial run of systems at sea today in Dublin Bay and off Greystones, writes Jehan Ashmore.
As previously reported on Afloat.ie, the Commissioners of Irish Lights 79m tender had undergone work that has involved the installation of a new radar mast, calorifier units and modifications to the bridge.
Arklow Marine Services carried out the work while the vessel was berthed in the port along Sir John Rogersons Quay.
The 2,625 tonnes buoy-handling vessel is expected to return to her homeport of Dun Laoghaire Harbour tonight.
#LighthouseTender – The Commissioners of Irish Lights ILV Granuaile (2000/2,625grt) an aids to navigation tender vessel, is undergoing steel modification works while berthed in Dublin Port, writes Jehan Ashmore.
Work on the 79m long tender which is moored at Sir John Rogersons' Quay close to the East-Link Bridge, is been carried out by Arklow Marine Services.
The work involves fabricating of a new radar mast, installation of calorifier units and modifications to the bridge.
Steel work modifications entail fitting under deck strengthening in way of ROV pads which are to be in accordance and to the approval of Lloyds.
Killybeg based Barry Electronics are supplying and fitting a new radar which requires a new mast with existing steelwork and platform being removed.
The new calorifier unit which is to replace existing plant will be piped in using 316 stainless steel pipe materials. It is expected the quayside work be completed by the middle of this month.
ILV Granuaile is the third tender to carry the name of the famous Mayo pirate Queen.
She was built by the Damen Shipyards Group, where the hull and superstructure were completed in Romania in Galati, the largest port town on the River Danube.
Following launching, she was towed through the Black Sea to the Netherlands for fitting out at another Damen shipyard, where work included the installation of electronic equipment.
#DOCKING SURVEY– The Commissioners of Irish Lights aids to navigation tender ILV Granuaile (2000/2,625grt) is currently at Cork Dockyard Ltd undergoing her scheduled docking survey, writes Jehan Ashmore.
The tender built in Romania over a decade ago and fitted out in the Netherlands by the Damen Shipyard Group, is required under regulation to drydock twice in five-yearly cycles. Her last docking was in 2009 and the the bouy-laying vessel is due her next scheduled docking in 2014.
Such docking is required by Classification Societies to inspect the underwater areas including hull, propellers, rudders, engine cooling systems, anchors, cables and anti corrosion systems.
At the same time the opportunity is taken to remove marine growth and to apply antifouling paint coatings to the underwater areas and to prepare and paint the ships hull. The principle dimensions of the hull are 79m long on a beam of 15m and with a shallow draft of 4.4m.
She has accommodation for an extra 10 persons or can accept modular housing on the after-deck where navigational aids (bouys) are stowed in cradles. Heavy lifting equipment including a 20 tonne crane with an outreach of 20m is used to position the bouys at pinpoint accuracy using satellite technology. There are 150 offshore buoys which warn mariners of the location of sand banks, reefs, and other offshore hazards near shipping routes.
A helicopter landing deck over the bow is used to transfer maintenance personnel and equipment to certain lighthouses.
ILV Granuaile's homeport is Dun Loaghaire Harbour, where she is seen frequently loading and unloading buoys alongside the various piers. On occasions she enters through the marina to berth alongside the Commissioners headquarters which includes a marine workshop depot facility, though this can only be done on certain tides and for a short duration.
Asides her primary duties serving the lighthouse authority, the vessel is capable of carrying out chain work, search and rescue, salvage and recovery, oil pollution control, towing, hydrographic applications, and ROV work.
#FORMER IRISH LIGHTS TENDER -With the Guardian 8 preparing to set sail from her builders homeport of Arklow this month, as previously reported on Afloat.ie, her owners Gardline Marine Services also operate a former Commissioners of Irish Lights tender, writes Jehan Ashmore.
The Great Yarmouth based company operate a multi-purpose fleet which includes the survey vessel Ocean Seeker (PHOTO). She was a familiar sight as the ILV Granuaile (1970/1,943grt) while serving for three decades from the Irish Lights marine depot in Dun Laoghaire Harbour.
Built by Fergusan Brothers of Port Glasgow, she was the last traditional tender for CIL in that her working deck was positioned forward. Apart from the short career of the Gray Seal, the 2000 built successor ILV Granuaile (the third to carry the name of the Mayo pirate queen) was the first custom built tender for CIL to introduce a radical design with an aft end work deck.
Regular guided tours will provide a fascinating insight into the work of the Commissioners of Irish Lights (CIL). The tours (first-come basis) are also available for disabled access and they start from 12 noon to 5pm, noting the last tour is 4.30pm. Location: Harbour Road, Dún Laoghaire.
Like most of the tours and events in Open House Dublin, there is no pre-booking required. Entry is FREE and on a first-come basis. For more information about what to expect from your tour or event, check the How It Works by clicking HERE.
CIL operate the 79m aids-to-navigation tender ILV Granuaile which is based at her homeport of Dun Laoghaire. The 2,625grt tender was built by the Dutch Damen Shipyard group in Galati, Romania. She was then towed to The Netherlands where further outfitting work was conducted. She entered service in 2000 and she is the third tender to be named after the Mayo pirate queen.
Occasionally ILV Granuaile can be seen moored alongside the berth adjacant to the marine depot accessed through Dun Laoghaire Marina, though she mostly calls to the harbour's western bight area, using her DP (dynamic-positioning) mode. Her design is ideally suited for buoy and chain work, search and rescue, salvage and recovery, towing, hydrographic applications, and ROV work.
She is shallow drafted at 4.4m and has heavy lifting equipment including a 20 tonne aft-mounted crane with an outreach of 20m. Accommodation is for a crew of 16 in addition there are cabins for a further 10 persons.
Sailing was not the only activity that took place in Dublin Bay last Saturday as the Northern Lighthouse Board's (NLB) multi-function tender NLV Pharos was busy at work, writes Jehan Ashmore.
The NLB is the Scottish equivalent of the Commissioners of Irish Lights (CIL) and it is not unusual for such vessels to share work duties beyond their respective jurisdictions. The 84m NLV Pharos is equipped with dynamic positioning and a 30-tonne main crane on her 300m2 aft-deck.
Overall she is similar in appearance to Irish lights ILV Granuaile which is based out of Dun Laoghaire. The Irish Lights tender built in Romania in 2000 tends to operate more often off the west coast during the summer months due to the more favourable weather conditions.
The 1,300 (dwt) deadweight tonnes NLV Pharos yesterday returned to her base in Oban from her Irish duties. The west coast base was established in 1904 and is also homeport to the service's smaller NLV Pole Star which is equipped with an 18-tonne crane on her 90m2 aft deck.
The facility in 2000 underwent a £4.2 million redevelopment to turn a buoy yard into a multi functional support base which is computer-linked to the NLB headquarters in Edinburgh.
In addition Trinity House which maintains the service for England and Wales operate the tenders THV Galtea,THV Patricia and the fast-response craft THV Alert from their base in Harwich.
Trinity House forms the trio of the General Lighthouse Authorities (GLA) alongside NLB and CIL. Each member of the GLA co-operate in the allocation of vessel-tender deployment.
Asides the varied and critical role of the tasks performed by the GLA's tenders, they are also available for charter to third parties. Between them the tenders can conduct buoy and chain work, search and rescue, lighthouse re-fuelling, salvage and recovery, towing, hydrographic applications and ROV work.
The decommissioned Codling Bank (Lanby) buoy is no longer in the water but rests firmly on a quayside in Dublin Port, writes Jehan Ashmore. In late July the Commissioners of Irish Lights withdrew the Lanby (Large Automated Navigation Buoy) was towed by the tender ILV Granuaile to the Coal Quay where the Lanby was hoisted out of the water.
The Lanby neighbours the adjacant Hammond Lane Company which is due to demolish the structure for scrapping. The removal of the Lanby, the last to serve in Irish waters, completes the withdrawal of Major Floating Aids to Navigation (MFAs) that also consisted of Lightships.
The Lanby was replaced with a Type 1 buoy to mark the Codling Bank offshore of Arklow. The new aids to navigation buoy has a focal in excess of 5-metres is fitted with a racon and Automatic Identification System (AIS).
Apart from loading scrap-metal the Coal Quay is also used by vessels for dry-cargoes trades such as animal feed, re-cycled glass and fertiliser.
