Waterways Ireland has confirmed that work will begin on the Royal Canal to excavate and reline 410 metres of the canal that runs between Lock 6 and 7 in the Phibsborough/Cabra area. The work is key to keeping the Canal navigable for a range of boats and will also address seepage through the canal embankment adjacent to Shandon Gardens.

The work which requires the dewatering of the canal will remove sediment and rubbish deposits from the central navigation channel before the construction of a new impervious lining to the canal. All material removed from the canals will be transported to licensed disposal facilities. Restoration of the existing towpath walls will also be undertaken to heritage approved standards.

Environmental surveys have been undertaken in full compliance with the regulatory authorities along with the planned removal of all fish to be carried under licence before onsite work begins.
A Traffic Management Plan will be agreed with Dublin City Council and implemented to keep traffic disruption to a minimum. Works are due to be completed by year end.

To facilitate works, the Royal Canal will be closed to navigation from 19 September 2011. The towpath from Lock 6 to the Liffey Junction Bridge on the north side and the Shandon Park area on the south side of the Canal will be closed for the duration of the contract. Following consultation and agreement with residents, a temporary roadway and bridge will also be constructed to provide access for the Coke Oven Residents through Shandon Park. This access will be suitable for emergency vehicles.

An engineer will be full time in attendance for the duration of the contract to ensure that issues which arise are dealt with in a prompt and efficient manner.

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.
