Three Voith-Schneider tugs that are surplus to the requirements of the Dublin Port Company towage fleet are for sale, writes Jehan Ashmore.
Two of the three tugs, Deilginis and Cluain Tarbh that are painted in a cream and black livery scheme, can be seen berthed at the North Wall Extension, close to the East-Link toll-lift bridge. Moored alongside them are their green hulled replacements.

The smallest of the tugs for sale is the 17-tonnes bollard pull Ben Eadar (1972/198grt) which was built by Richard Dunston (Hessle) Ltd. She is berthed elsewhere in the port alongside the former Dundalk Port Company owned dredger Hebble Sand, which too has been recently put up for sale. For more information about the grab-hopper dredger click HERE.

Ben Eadar was decommissioned in 2009 and her 35-tonnes bollard-pull fleetmates Cluain Tarbh (1991/268grt) built by McTay Marine of Bromborough and Deilginis (1996/335grt) remained in service until late last year.

Of the trio Deilginis is the last tug commissioned by the Dublin Port & Docks Board (DP&DB) and the 30m tug is also the last to carry a traditional naming theme based on Dublin Bay coastal suburbs spelt in Irish. Deilginis is the Irish for Dalkey, Cluain Tarbh is for Clontarf and Ben Eadar is a translation for Howth.

Deilginis was launched from Astilleros Zamakona S.A. in Bilbao, the same Spanish shipyard that was commissioned by the Dublin Port Company to build two 50-tonnes bollard pull tractor tug sisters. The first newbuild Shackleton entered service late last year and she was followed by Beaufort in early 2010. In March of that year the tugs that cost €6m each to build were officially named in a joint ceremony.

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.
