Stormy winds disrupt training weekend plans

A very large contingent of 18 search divers were to partake in the training weekend in Bere Island this past weekend but alas the weather and the sea once again gave a grim reminder of their inexorable power when a storm in the Atlantic battered coastlines and forced the cancellation of the weekend. Predictive wind forecasts were showing wave heights in excess of 18 feet which would indeed be very dangerous and diving at sea would be a foolhardy exercise.
Undeterred dive training did take place on Sunday in County Tipperary in an old disused slate quarry which has since filled with freshwater to a depth of 40 meters. The quarry in Portroe is now ran commercially as a diving centre for use by divers and is ideal for training when the sea is too rough and the local rivers are swollen with flood water. With the quarry being so deep it provides the perfect venue for divers to stay dived up and accustomed to the detrimental effects of nitrogen narcosis when diving deep. While the effects of Nitrogen gas on the human mind at depth is still not fully understood by science; any diver who has dived beyond 30 meters is well aware of the effects with some divers overcome by a feeling of jubilation while others experience analytical narrowing and depressive effects while on the dive. While every diver experiences this some divers are much more prone than others and by staying dived up to depth throughout the year a diver ensures they are better able to deal with the effects.
Divers badly effected by the phenomenon can sometimes surface remembering very little of the dive which is why divers always dive in pairs; the amazing aspect of the phenomenon is that on ascending all effects disappear very quickly with no lasting effects; much akin to a hangover with a much quicker recovery period ! In addition to the depth Portroe quarry is also generally very cold and this makes the diving that bit more arduous and challenging; all groups were broken into dive teams depending on dive experience and during the day many diving skills such as mask clearing, regulator switches, buoyancy control, SMB deployment, use of diver propulsion vehicles, gas shutdowns and many other skills were effectively practised. It was great to see so many rainbow trout now living in the quarry as well as a good number of large freshwater eels , some of which were seen free swimming.
While it was disappointing that the weekend was cancelled there was no option given the sea forecast, but hopefully it can be rescheduled in the coming weeks if there is sufficient interest.
Everyone in the search unit would like to extend their sympathies to the Reidy, Keegan and Whelan families on their recent tragic losses.

National Search and Recovery training day a resounding success on the river Blackwater

Last weekend was the scheduled weekend for all search and recovery units affiliated to the Irish Underwater Council to partake in a national search and recovery training weekend. While many units done this in one session it was decided to do a much bigger exercise on the river Blackwater.

The search unit has been successfully utilising side scan technology for a number of years on local waterways but recently it was decided to start 3D mapping of many of the local waterways. This would allow the search unit to identify any object underwater that resembles a missing person such as a large tree trunk. The next step in the coming months will be to dive all of these objects, identify them and record them on a 3D reference map; this would provide invaluable information for future search operations and should reduce down search time. While it would be impractical to cover all stretches of local rivers, it is feasible to do this for all higher risk areas. The concept was recently discussed with the manufacturer of the side scan technology in Sweden and he was only aware of one other group who had done this ( a group in Sweden). After some good exercises on Saturday scanning stretches of the Blackwater in Fermoy, Sunday would comprise of diving operations in identifying some of these marks.

Unfortunately with the recent heavy rain fall river conditions were very poor diving with the river water more akin to dark chocolate giving no visibility. Nonetheless each of the dive teams overcame the austere dive conditions and identified a number of marks, well done to all involved.

There is probably no sport in the world that can be as frustrating as scuba diving, weeks of careful planning, huge volumes of preparation and then strong winds at sea could make diving impossible or the advent of a plankton bloom could destroy visibility making shipwreck exploration impossible. On the other hand for those who persevere and practice diving skills in the bad conditions, every so often the dogmatic group who persevere can be rewarded with a truely inspirational experience. Last weekend would prove to be such a day and for the four divers who travelled to Ferrypoint they would be well rewarded, with a stiffening SE force 3 breeze for the 13 kilometer journey to the wreck of the Folia; the divers were unsure whether the sea conditions would worsen when all of a sudden a large pod of dolphins appeared and shortly after they appeared the sea flattened to idyllic sea conditions. With a fishing boat fishing over the stern of the Folia, it was decided to descend to the bow the deeper section of the wreck at 40 meters and it would prove to be an inspirational decision. As the first two divers Gearoid O Looney and Timmy Carey hit the water, the site of the wreck coming into view at 22 meters was a very good sign that visibility was excellent. Dropping down onto the impressive bow of the large steamship and seeing the two bow anchors firmly wedged into the anchor lockers , you get a sense of the size of the large vessel.

The Folia was originally named Principe di Piemonte when she was built for the Lloyd Sabaudo Line of Italy in 1907. The ship was built by Sir James Laing & Sons, Sunderland, and launched on 26 February 1907. In 1913 the ship was sold to Canadian Northern Railways, renamed Principello and chartered to Uranium Steamship Co. for their Rotterdam to New York service.In 1916 the Principello was acquired by Cunard to help replace the many vessels they had already lost in the war. Cunard renamed the ship Folia and it was used on the transatlantic route. On Sunday 11 March 1917 the Folia was sailing 4 miles off Ram Head near to Ardmore County Waterford when she was torpedoed without warning by U 53, with the loss of five of the crew. Since the clubs inception 30 years ago, the Folia had always remained a favourite dive site for many club members, despite the imposing depth of 40 meters; at which divers are very prone to suffering nitrogen narcosis or rapture of the deep (which has a temporary effect on a diver similiar to that of consuming alcohol on an empty stomach !!!). While the Folia is now sunk almost a century, the shipwreck keeps changing and is never the same dive twice as it is ever so slowly decomposing. The large bow section is quite impressive and with now of the hull platings now having gaping holes it is somewhat reminiscent of the ss Justicia in 70 meters off Donegal. With almost 15 meters visibility the divers would soon be exploring the deep recesses of the bow before heading aft over the winches and anchor chains and passing the remnants of trench digging machines destined for the troops on the Western Front in WW1. On the surface Mike Reidy and George Goggin would be treated to an aquatic display of dolphins jumping from the water around the boat while the divers could hear the loud squeeking of the dolphins who could undoubtedly see the divers even though the divers could never see the dolphins due to their incredible speed.Approaching back to the shotline after an amazing exploration dive it was very sad to see that a fishing net lost at sea that was draped over a large section of wreckage near the bow had claimed many victims. With the net lost lots of fish life would still get caught in the net and inevitably perish there, with a large number of large spider crab and edible crabs stuck firmly in the net. Ten minutes later after cutting a large amount of netting 7 crabs would again be free and quickly retreating away from the net; although one of the divers got nipped from one the large spider crabs for his trouble!!

Surfacing slowly to eliminate the body of excess Nitrogen bottles both were able to ponder back on a fantastic dive when the dive would be capped by the sight of a very small sea horse ; which is a very rare sight in Irish waters. The second dive of the day in the lee of Capel Island would be equally as good with George and Mike logging 40 minutes dive time in an environment teeming with marine life.

Well done also to Joost who led Peter Whelan and Matt Culloty on a intensive extended range training session. 2 sessions were completed one of 1hr and the second dive of 45 minutes practicing the various techniques, shut downs, gear change removal, buoyancy, lay down of lines, 10 minutes of diving no mask etc ! also responding to simulated emergency situations.Next is a trip to 40 meters where they will once again be practiced, before the final dive of 50 meters.Best of luck to both.
Not content with two separate training sessions at the weekend in two different locations , a full day session of search and recovery training also took place on Saturday and again this proved to be very successful

A big thanks from everyone in the club to SAMCO Engineering for the recent assistance with renovation of the search launch; as usual the workmanship was to an excellent standard.
