The Marine Institute's two research vessels, RV Celtic Explorer and RV Celtic Voyager are to lead Europe with an all-time record of 627 days spent at sea of between both ships, well above the average for equivalent European research vessels.
In 2011, the RV Celtic Explorer is scheduled for 17 surveys in Irish waters resulting in 344 days at sea and the RV Celtic Voyager with 29 surveys resulting in 283 days at sea. In comparison, in 2010 the RV Celtic Explorer spent 308 days at sea with 18 surveys and as well as undergoing a refit. The Celtic Voyager took 280 sea-going days resulting in 32 surveys.

These figures compare favourably with our European counterparts, reflecting a high level of activity on national and international research and monitoring programmes.

Work duties in 2011 for the Galway based vessels will range from fisheries surveys to underwater mapping and from climate studies to deepwater surveys with the remotely operated submersible ROV Holland 1. The work schedule will facilitate training missions and to carry out essential maintenance work on Ireland's network of data buoys that, in parallel to their research function, supply the vital information on which weather and shipping forecasts are based.

The increased activity of the research vessels reflects the growing imperative to understand and sustainably manage the economic potential of our offshore marine territories, an area over ten times that of Ireland itself.

A major role of the ships' workload will be commercial fish stock assessments. Together they are to devote 141 days on stock surveys in support of the sustainable management of Ireland's fisheries.

The RV Celtic Voyager will conduct underwater television surveys of valuable prawn stocks off the Aran Islands, the Irish and Celtic Seas, working on blue whiting, a survey of herring stocks in the north-west. In addition a comprehensive 54-day annual Irish Groundfish Survey which will take place in stages all around the Irish coast from September to December.

The survey will be the largest undertaken by an Irish research vessel and is essential to providing the scientific data used to inform the annual quota negotiations required in Brussels each year.

At 65.5m RV Celtic Explorer (2,425grt) accommodates 35 personnel and up to 21 scientists and 31.4m RV Celtic Voyager (340grt) with up to 8 scientists and a maximum endurance of 14-day days.

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.
