It has been confirmed by the Department of Defence that it is currently exploring the possibility of purchasing two New Zealand navy ships to be used for fisheries protection duties in the Irish Sea.

The Irish Examiner understands that the ships are 'Lake Class' 55 m (180ft) inshore patrol vessels.

The Royal New Zealand Navy was supplied with four of them by British shipbuilders Brooke Marine. Two have since been decommissioned.

In a statement, the Department of Defence said: "A potential acquisition by Ireland of two Royal New Zealand Navy Inshore Patrol Vessels is currently being explored. No contractual agreement has been signed (as of yet), and in accordance with normal practice the Department does not comment on commercial discussions."

The ships being looked at are much smaller than the more modern vessels used by the Irish Naval Service.

The navy needs larger vessels to patrol the Atlantic, particularly due to the rough weather that can be experienced there.
However, the weather is not as bad in the Irish Sea and, therefore, smaller vessels like the 'Lake Class' inshore patrol boats would be ideal there.

Also, and just as importantly, the New Zealand ships need smaller crews than the larger Naval Service vessels.

Typically a Naval Service ship needs a crew of around 45 personnel. The Lake Class ships can be crewed with just 25 people.

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.
