#Fishing - Key to proposals to end fish discards in this year's reform of the Common Fisheries Policy (CFP) is the introduction of new technology like wheelhouse cameras and 'smart nets'.

So argues EU Fisheries Commissioner Maria Damanaki, as BBC News reports on trials of new net designs that can separate fish catches and reduce damage to the seabed.

One of the fishing net innovations involves a bendable plastic grid attached to the middle of a trawl net that allows smaller fish and juveniles to pass through while snaring the valuable larger catch.

Another design, the Rollerball net, attempts to eliminate the problem of heavy trawling gear churning up debris on the sea floor while reducing drag and saving on boats' fuel bills.

Assuaging concerns over the prohibitive costs for fishermen, Damanaki says she hopes that such 'smart nets' will be subsidised by as much as 85% - while emphasising that the adoption of new technology could mean the difference between being allowed to fish or being banned from the ocean.

Wheelhouse CCTV cameras are another method that has been shown to reduce discards to less than 1% in some cases - and Damanaki says they will be essential if the CFP reforms indeed include a zero tolerance policy on fish discards.

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.
