#lighthouses -  Contributory feedback from marine users of navigational aids is been sought from Irish Lights of its Aids to Navigation provision around the coasts of Ireland. 

Every five years, the General Lighthouse Authorities (GLA), comprising Irish Lights, Northern Lighthouse Board and Trinity House in the UK, conduct this review to assess AtoN requirements.

Over time changes can occur which affect Aids to Navigation requirements and their development such as trade patterns, vessel types and volume, the seabed, development of offshore projects or changes in technology. The review will include individual AtoN and systems of AtoN to ensure international standards are met.

All users of marine Aids to Navigation are invited to contribute to the review by commenting on the usefulness and usability of existing AtoN provided by the GLA. Input is particularly welcome on any proposed requirement for the provision of additional AtoN; improvements to the current mix of AtoN; technological developments or additional services. Feedback is also welcomed on Irish Lights data service which provides near real time meteorological information.

Emphasising the critical importance of user input Captain Robert McCabe, Director of Operations and Navigation Services, Irish Lights said, “International standards require average availability ranging from 97 percent to 99.8 percent and Marine Aids to Navigation must serve all users of the sea, from small leisure and fishing craft to large liners and cargo vessels. Input from experienced users is essential to the process of defining the correct mix of Aids to Navigation. Local knowledge and experience built through time at sea cannot be replaced by desktop analysis no matter how modern and sophisticated the tools may be”.

Responses should be submitted before 30th July 2019 by emailing [email protected] or write to Navigation Services, Commissioners of Irish Lights, Harbour Road, Dun Laoghaire, Co. Dublin.

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.
