The second leg of the MOVE 2 survey of the mobility of sediment waves and sand banks will be carried out in the Irish Sea off Wicklow and Wexford from next weekend.

As noted previously on Afloat.ie, reporting on the survey in March this year, it will involve the use of multi-beam echo sounders and sub-bottom profilers at various sites, and sediment grabs samples will also be taken.

Survey operations will be carried out on a 24-hour schedule between Saturday 4 and Monday 13 December by the RV Celtic Voyager (callsign EIQN), which will be displaying appropriate lights and signals.

This survey is being carried out in support of ongoing research at the SFI Centre for Energy, Climate and Marine research and innovation (MaREI) and the Irish Centre for Research in Applied Geosciences (iCRAG).

More on the survey including coordinates and contact details can be found in Marine Notice No 63 of 2021, a PDF of which is available to download 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.
