#DublinPort - The Dublin Port Company has posted this incredible timelapse video of the four-month restoration of the capital's 129-year-old diving bell.

As previously reported on Afloat.ie, the Docklands mainstay opened as Dublin's newest tourist attraction this past July, with interpretive panels detailing its use in the construction of the Liffey quay walls from the late 19th century till the 1950s.

Its original designer, Bindon Blood Stoney, was also the engineer responsible for such landmarks as O'Connell Bridge and the Boyne Viaduct bridge in Drogheda.

Still having pride of place on Sir John Rogerson's Quay, the diving bell is now elevated an extra two metres allowing access for the public underneath.

#DivingBell - Engineers worked 82 feet beneath the surface of the North Channel to repair a seabed cable linking Northern Ireland's power grid with Scotland.

According to HeraldScotland, the repair crew used a diving bell style device to safely reach the site some 4km from the Scottish mainland and fix the break in the Moyle Interconnector.

The N-Sea 'incubator' design is a more modern version of the diving bell design used in the construction of Dublin's deep-water quays between the 1870s and 1950s.

#DublinPort - Dublin Port's 140-year-old diving bell is set to be restored as a tourist attraction, as the Irish Independent reports.

The diving bell was first used in construction of the capital's deep-water quays in 1871, allowing for water to be pumped out and air to be pumped in for workers to make the river bed level, acting like a mobile caisson.

It was last used in the building of quayside walls as recently as 1958, and following a campaign to save it from the scrapheap in the 1980s it was moved to its present location on Sir John Rogerson's Quay.

Now it will form the basis of a new interpretive centre to be readied this June, where visitors will be able to access the 90-tonne device from beneath and learn more about its fascinating history.

The Irish Independent has more on the story HERE.

More from Dublin Port Company:

Have you ever passed by the odd looking, bell-shaped, red metal structure standing tall on Sir John Rogerson's Quay and wondered what it is? You could be forgiven for thinking it is a modern art sculpture or misplaced mound of metal. It is in fact an ingenious feat of Irish engineering that was essential in building Dublin's quay walls for 87 years. This is Dublin Port's "Diving Bell".

Dublin Port Company today announced a new project that will shed light on this important artefact and will transform the Diving Bell into a new interpretive exhibition that explains its origin and history.

The Diving Bell was designed by the port engineer Bindon Blood Stoney (1828 to 1907) and built by Grendon and Co., Drogheda. It was delivered to the Port in 1866, entered service in 1871 and was used in the building of the Port's quay walls until 1958. Stoney was a prodigious engineer and among his achievements were the building of the Boyne Viaduct in Drogheda, the construction of O'Connell Bridge and the building of many of the Port's quay walls including Sir John Rogerson's Quay and North Wall Quay Extension.

The Diving Bell was used in the building of the Port's quay walls from the Victorian era right up until almost the 1960s. It was a ground-breaking piece of engineering innovation in its day.

Its lower section was hollow and bottomless, providing just enough room for six men to work at a time. Once lowered into position on the riverbed, the crew entered through an access funnel from the surface and compressed air was fed in from an adjacent barge. The men inside the bell worked on the river bed exposed at their feet, excavating the site where a massive concrete block would later go; all the excavated soil was stashed in trays hanging inside the bell, and brought up when the bell was lifted.

The project, which commences this week and opens in mid-June 2015, will elevate the 13m tall, 90 tonne Diving Bell onto a two metre steel structure, creating a ramped public access route underneath. A water feature will also be installed beneath the structure accompanied by a series of interpretative panels explaining the historical, social and engineering significance of the Diving Bell. The new exhibition will be illuminated at night time using energy efficient LED lighting.

The project has been designed with the expertise of a range of people including the architect Sean O'Laoire, the sculptor Vivienne Roche, Tom Cosgrave (professor of engineering at the University of Limerick) and Mary Mulvihill of Ingenious Ireland.

This is the first project in Dublin Port's plan to create a 'distributed museum' of attractions across the Dublin docklands and into Dublin Port to preserve the port's industrial heritage and history.

Weslin Construction Ltd. has been appointed to carry out the project, which will be completed by mid-June 2015, when the newly reconfigured Diving Bell will open again to the city.

Eamonn O'Reilly, Chief Executive, Dublin Port Company said: "The Diving Bell is a remarkable feat of Irish engineering and Dublin Port Company is proud to invest in its transformation and bring the history of this magnificent structure to life along the Liffey. True to the commitment in our Masterplan, we are working to better integrate Dublin Port and the city. Developing the Diving Bell is the first step in our plan to create a distributed museum of port and industrial heritage attractions across the Dublin docklands and into the port. We are confident that the Diving Bell will give Dubliners and visitors to the city a true sense of Dublin as a port city with a wealth of industrial heritage to discover."

Betty Ashe of St. Andrew's Resource Centre, Pearse Street, said: "I am delighted that the next phase of the Diving Bell Project is now underway, having been involved in a Millennium project with St. Andrew's Resource Centre, the DDDA and Dublin Port Company to save and restore this fascinating artefact from the Victorian era. As a port community, we have a duty to preserve local history for future generations. I thank Dublin Port Company for sharing that vision and giving the Diving Bell a prominent place in the history books for this community and our city."

The Irish Coast Guard

The Irish Coast Guard is Ireland's fourth 'Blue Light' service (along with An Garda Síochána, the Ambulance Service and the Fire Service). It provides a nationwide maritime emergency organisation as well as a variety of services to shipping and other government agencies.

The purpose of the Irish Coast Guard is to promote safety and security standards, and by doing so, prevent as far as possible, the loss of life at sea, and on inland waters, mountains and caves, and to provide effective emergency response services and to safeguard the quality of the marine environment.

The Irish Coast Guard has responsibility for Ireland's system of marine communications, surveillance and emergency management in Ireland's Exclusive Economic Zone (EEZ) and certain inland waterways.

It is responsible for the response to, and co-ordination of, maritime accidents which require search and rescue and counter-pollution and ship casualty operations. It also has responsibility for vessel traffic monitoring.

Operations in respect of maritime security, illegal drug trafficking, illegal migration and fisheries enforcement are co-ordinated by other bodies within the Irish Government.

On average, each year, the Irish Coast Guard is expected to:

  • handle 3,000 marine emergencies
  • assist 4,500 people and save about 200 lives
  • task Coast Guard helicopters on missions

The Coast Guard has been around in some form in Ireland since 1908.

Coast Guard helicopters

The Irish Coast Guard has contracted five medium-lift Sikorsky Search and Rescue helicopters deployed at bases in Dublin, Waterford, Shannon and Sligo.

The helicopters are designated wheels up from initial notification in 15 minutes during daylight hours and 45 minutes at night. One aircraft is fitted and its crew trained for under slung cargo operations up to 3000kgs and is available on short notice based at Waterford.

These aircraft respond to emergencies at sea, inland waterways, offshore islands and mountains of Ireland (32 counties).

They can also be used for assistance in flooding, major inland emergencies, intra-hospital transfers, pollution, and aerial surveillance during daylight hours, lifting and passenger operations and other operations as authorised by the Coast Guard within appropriate regulations.

Irish Coastguard FAQs

The Irish Coast Guard provides nationwide maritime emergency response, while also promoting safety and security standards. It aims to prevent the loss of life at sea, on inland waters, on mountains and in caves; and to safeguard the quality of the marine environment.

The main role of the Irish Coast Guard is to rescue people from danger at sea or on land, to organise immediate medical transport and to assist boats and ships within the country's jurisdiction. It has three marine rescue centres in Dublin, Malin Head, Co Donegal, and Valentia Island, Co Kerry. The Dublin National Maritime Operations centre provides marine search and rescue responses and coordinates the response to marine casualty incidents with the Irish exclusive economic zone (EEZ).

Yes, effectively, it is the fourth "blue light" service. The Marine Rescue Sub-Centre (MRSC) Valentia is the contact point for the coastal area between Ballycotton, Co Cork and Clifden, Co Galway. At the same time, the MRSC Malin Head covers the area between Clifden and Lough Foyle. Marine Rescue Co-ordination Centre (MRCC) Dublin covers Carlingford Lough, Co Louth to Ballycotton, Co Cork. Each MRCC/MRSC also broadcasts maritime safety information on VHF and MF radio, including navigational and gale warnings, shipping forecasts, local inshore forecasts, strong wind warnings and small craft warnings.

The Irish Coast Guard handles about 3,000 marine emergencies annually, and assists 4,500 people - saving an estimated 200 lives, according to the Department of Transport. In 2016, Irish Coast Guard helicopters completed 1,000 missions in a single year for the first time.

Yes, Irish Coast Guard helicopters evacuate medical patients from offshore islands to hospital on average about 100 times a year. In September 2017, the Department of Health announced that search and rescue pilots who work 24-hour duties would not be expected to perform any inter-hospital patient transfers. The Air Corps flies the Emergency Aeromedical Service, established in 2012 and using an AW139 twin-engine helicopter. Known by its call sign "Air Corps 112", it airlifted its 3,000th patient in autumn 2020.

The Irish Coast Guard works closely with the British Maritime and Coastguard Agency, which is responsible for the Northern Irish coast.

The Irish Coast Guard is a State-funded service, with both paid management personnel and volunteers, and is under the auspices of the Department of Transport, Tourism and Sport. It is allocated approximately 74 million euro annually in funding, some 85 per cent of which pays for a helicopter contract that costs 60 million euro annually. The overall funding figure is "variable", an Oireachtas committee was told in 2019. Other significant expenditure items include volunteer training exercises, equipment, maintenance, renewal, and information technology.

The Irish Coast Guard has four search and rescue helicopter bases at Dublin, Waterford, Shannon and Sligo, run on a contract worth 50 million euro annually with an additional 10 million euro in costs by CHC Ireland. It provides five medium-lift Sikorsky S-92 helicopters and trained crew. The 44 Irish Coast Guard coastal units with 1,000 volunteers are classed as onshore search units, with 23 of the 44 units having rigid inflatable boats (RIBs) and 17 units having cliff rescue capability. The Irish Coast Guard has 60 buildings in total around the coast, and units have search vehicles fitted with blue lights, all-terrain vehicles or quads, first aid equipment, generators and area lighting, search equipment, marine radios, pyrotechnics and appropriate personal protective equipment (PPE). The Royal National Lifeboat Institution (RNLI) and Community Rescue Boats Ireland also provide lifeboats and crews to assist in search and rescue. The Irish Coast Guard works closely with the Garda Siochána, National Ambulance Service, Naval Service and Air Corps, Civil Defence, while fishing vessels, ships and other craft at sea offer assistance in search operations.

The helicopters are designated as airborne from initial notification in 15 minutes during daylight hours, and 45 minutes at night. The aircraft respond to emergencies at sea, on inland waterways, offshore islands and mountains and cover the 32 counties. They can also assist in flooding, major inland emergencies, intra-hospital transfers, pollution, and can transport offshore firefighters and ambulance teams. The Irish Coast Guard volunteers units are expected to achieve a 90 per cent response time of departing from the station house in ten minutes from notification during daylight and 20 minutes at night. They are also expected to achieve a 90 per cent response time to the scene of the incident in less than 60 minutes from notification by day and 75 minutes at night, subject to geographical limitations.

Units are managed by an officer-in-charge (three stripes on the uniform) and a deputy officer in charge (two stripes). Each team is trained in search skills, first aid, setting up helicopter landing sites and a range of maritime skills, while certain units are also trained in cliff rescue.

Volunteers receive an allowance for time spent on exercises and call-outs. What is the difference between the Irish Coast Guard and the RNLI? The RNLI is a registered charity which has been saving lives at sea since 1824, and runs a 24/7 volunteer lifeboat service around the British and Irish coasts. It is a declared asset of the British Maritime and Coast Guard Agency and the Irish Coast Guard. Community Rescue Boats Ireland is a community rescue network of volunteers under the auspices of Water Safety Ireland.

No, it does not charge for rescue and nor do the RNLI or Community Rescue Boats Ireland.

The marine rescue centres maintain 19 VHF voice and DSC radio sites around the Irish coastline and a digital paging system. There are two VHF repeater test sites, four MF radio sites and two NAVTEX transmitter sites. Does Ireland have a national search and rescue plan? The first national search and rescue plan was published in July, 2019. It establishes the national framework for the overall development, deployment and improvement of search and rescue services within the Irish Search and Rescue Region and to meet domestic and international commitments. The purpose of the national search and rescue plan is to promote a planned and nationally coordinated search and rescue response to persons in distress at sea, in the air or on land.

Yes, the Irish Coast Guard is responsible for responding to spills of oil and other hazardous substances with the Irish pollution responsibility zone, along with providing an effective response to marine casualties and monitoring or intervening in marine salvage operations. It provides and maintains a 24-hour marine pollution notification at the three marine rescue centres. It coordinates exercises and tests of national and local pollution response plans.

The first Irish Coast Guard volunteer to die on duty was Caitriona Lucas, a highly trained member of the Doolin Coast Guard unit, while assisting in a search for a missing man by the Kilkee unit in September 2016. Six months later, four Irish Coast Guard helicopter crew – Dara Fitzpatrick, Mark Duffy, Paul Ormsby and Ciarán Smith -died when their Sikorsky S-92 struck Blackrock island off the Mayo coast on March 14, 2017. The Dublin-based Rescue 116 crew were providing "top cover" or communications for a medical emergency off the west coast and had been approaching Blacksod to refuel. Up until the five fatalities, the Irish Coast Guard recorded that more than a million "man hours" had been spent on more than 30,000 rescue missions since 1991.

Several investigations were initiated into each incident. The Marine Casualty Investigation Board was critical of the Irish Coast Guard in its final report into the death of Caitriona Lucas, while a separate Health and Safety Authority investigation has been completed, but not published. The Air Accident Investigation Unit final report into the Rescue 116 helicopter crash has not yet been published.

The Irish Coast Guard in its present form dates back to 1991, when the Irish Marine Emergency Service was formed after a campaign initiated by Dr Joan McGinley to improve air/sea rescue services on the west Irish coast. Before Irish independence, the British Admiralty was responsible for a Coast Guard (formerly the Water Guard or Preventative Boat Service) dating back to 1809. The West Coast Search and Rescue Action Committee was initiated with a public meeting in Killybegs, Co Donegal, in 1988 and the group was so effective that a Government report was commissioned, which recommended setting up a new division of the Department of the Marine to run the Marine Rescue Co-Ordination Centre (MRCC), then based at Shannon, along with the existing coast radio service, and coast and cliff rescue. A medium-range helicopter base was established at Shannon within two years. Initially, the base was served by the Air Corps.

The first director of what was then IMES was Capt Liam Kirwan, who had spent 20 years at sea and latterly worked with the Marine Survey Office. Capt Kirwan transformed a poorly funded voluntary coast and cliff rescue service into a trained network of cliff and sea rescue units – largely voluntary, but with paid management. The MRCC was relocated from Shannon to an IMES headquarters at the then Department of the Marine (now Department of Transport) in Leeson Lane, Dublin. The coast radio stations at Valentia, Co Kerry, and Malin Head, Co Donegal, became marine rescue-sub-centres.

The current director is Chris Reynolds, who has been in place since August 2007 and was formerly with the Naval Service. He has been seconded to the head of mission with the EUCAP Somalia - which has a mandate to enhance Somalia's maritime civilian law enforcement capacity – since January 2019.
