Owners of boats moored on the River Shannon and its tributaries are counting the costs of the recent icy conditions which have caused the sinking of a high number of vessels.
The Irish Times reports that the Inland Waterways Association of Ireland (IWAI) has advised all boatowners to check their boats after reports of sinkings across six counties.
Among the sunken vessels are a 35ft cruiser opposite the Landmark Hotel in Carrick-on-Shannon. The worst situation is reportedly in Shannon Harbour, with an unusually high number of boats sunk or partially submerged.
Sunken boats often require full refitting to replace damaged finishings and damaged electronics. But of greater concern is the potential environmental impact due to fuel or oil spills, or the leaking of antifreeze and other chemicals.
The IWAI has blamed poor 'winterisation' as a factor in the sharp increase in sinkings.
Winterisation involves the closing of sea cocks to prevent water entering the intake pipes and potentially bursting them when it freezes, or leaking when it thaws.
"Owners need to check on their craft regularly or have a local do it," said IWAI president Paul Garland. "The lessons learned this winter must be taken seriously. Heaters may not be enough; all sea cocks have to be shut."

Shipyards

Afloat will be focusing on news and developments of shipyards with newbuilds taking shape on either slipways and building halls.

The common practice of shipbuilding using modular construction, requires several yards make specific block sections that are towed to a single designated yard and joined together to complete the ship before been launched or floated out.

In addition, outfitting quays is where internal work on electrical and passenger facilities is installed (or upgraded if the ship is already in service). This work may involve newbuilds towed to another specialist yard, before the newbuild is completed as a new ship or of the same class, designed from the shipyard 'in-house' or from a naval architect consultancy. Shipyards also carry out repair and maintenance, overhaul, refit, survey, and conversion, for example, the addition or removal of cabins within a superstructure. All this requires ships to enter graving /dry-docks or floating drydocks, to enable access to the entire vessel out of the water.

Asides from shipbuilding, marine engineering projects such as offshore installations take place and others have diversified in the construction of offshore renewable projects, from wind-turbines and related tower structures. When ships are decommissioned and need to be disposed of, some yards have recycling facilities to segregate materials, though other vessels are run ashore, i.e. 'beached' and broken up there on site. The scrapped metal can be sold and made into other items.
