#Trident - Trident won't be coming to Northern Ireland - as there are no waters deep enough to host the nuclear deterrent submarines, according to one MLA.

As the Belfast Telegraph reports, Ulster Unionist MLA Steve Aiken says that from his own experience, the region has no suitable deepwater ports or inlets necessary for the 150m-long Vanguard-class submarines in the Trident programme, which are currently stationed off western Scotland.

"It's not deep enough, we can't do it," he said. "I tried to bring my submarine, HMS Sovereign, to Belfast towards the end of its time.

"Because you need deep water at all states of the tide, even though entrance to Belfast Lough is dredged to 10 metres, it's not deep enough.

"You can't bring it into Larne because there is a rock sill coming into Larne Lough which you would have to blast out; same for Carlingford Lough, and Lough Foyle is too shallow."

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.
