#Jellyfish - Swimmers have been warned away from Seapoint and Sandycove on the south shores of Dublin Bay after sightings of potentially dangerous lion’s mane jellyfish in the water.

Dun Laoghaire-Rathdown County Council has put up warning signs in the relevant areas to advise the public on the large jellyfish, whose stings from hundreds of tentacles can cause anaphylactic shock — even many days after they have beached.

#Jellyfish - Organisers of tomorrow's Ironman triathlon in Dublin Bay are currently monitoring the appearance of Lion's Mane jellyfish in the waters of the swimming course.

According to The Irish Times, the Ironman event is scheduled to begin early on Sunday 14 August with a 1.9km swim across the bay from Sandycove, which has been red-flagged since Wednesday after a number of the dangerous jellyfish washed up on the beach.

The Lion's Mane's powerful sting is known to cause anaphylactic shock, which is potentially fatal – and the sting is still potent even days after a jellyfish has died, as previously reported on Afloat.ie.

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.
