#multibeam – A new multibeam sonar system fitted to the Marine Institute's Research Vessel Celtic Voyager will allow a new level of detail of seabed features to be captured during important mapping surveys around our coast.

It will greatly increase the capability of the vessel to acquire seabed bathymetry data as part of the INFOMAR seabed mapping program and other projects.

See how the new sonar operates in the promo vid below.

The new EM2040 system will be the primary mapping tool during upcoming INFOMAR survey operations offshore County Galway, Clare, and West Cork, extending the Irish seabed coverage around our coast.

This seabed mapping activity will support ocean energy development and fisheries management, and provide improved navigation for safe shipping and transport.

It was successfully installed onboard the RV Celtic Voyager during a recent dry docking in Killybegs, Co. Donegal.

The EM2040 system which was purchased from Kongsberg Maritime was installed on the vessel at the Department of Marine shipyard in Killybegs by P&O Maritime with the assistance of Mooney Boats of Killybegs.

This system replaces an older system which has been in use since 2000.

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.
