The Department of Transport has been advised that Greenlink Interconnector Ltd (GIL) is developing an electricity interconnector between the southeast of Ireland, from Great Island in Co Wexford to the southwest of Wales at Pembroke in Pembrokeshire.

To allow the offshore cable to be pulled onshore in a later stage, a shore-based sub-contractor Very Large Crude Carrier (VLCV) has completed drilling and diving operations at the Baginbun Beach landfall site for installation of two high-density polyethylene (HDPE) ducts with a bell mouth. Both pipes are stabilised with six rock bags per pipe.

All operations related to the installation of the HDPE ducts are completed. The HDPE pipes and rock bags will be in place until effective high-voltage direct current (HVDC) cable installation, which is expected to start on Monday 1 April. The dive preparations will start from around Wednesday 20 March.

Coordinates and a diagram of the survey area as well as contact details and more can be found in Marine Notice No 09 of 2024, attached below.

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.
