Considerably Late Ferry For CalMac's Firth of Clyde Route Has Sea Trials: ‘Overwhelmingly Positive’ – Ferguson Marine

A massively delayed ferry built in Scotland to serve CalMac, the MV Glen Sannox had carried out first sea trials which have been hailed as "overwhelmingly positive" by shipbuilder Ferguson Marine following four days of tests on the Firth of Clyde.

The chief executive of the Port Glasgow shipyard, David Tydeman, said on Friday, that the results of the trials, in which the 102m long vessel moved under its own power for the first time, "clearly demonstrated the advanced technology it will bring to the CalMac fleet".

With the result of the sea trails, the declaration is likely to come as a huge relief to Scottish Government ministers of the nationalised shipyard, who have expressed increasing frustration with the Ferguson ferry fiasco contract. This has led to costs of more than tripling, from the original £97 million for both the leadship ferry and twin MV Glen Rosa which are running six years late, as they were due to enter service in 2018.

There are however fears that remain at Ferguson Marine as the shipyard’s latest review of the ferry project could see the twins be delayed yet further.

When Glen Sannox eventually enters service for CalMac, the newbuild will be the west coast operator’s second largest with space for more than 850 passengers and 127 cars.

During the sea-trails, Glen Sannox sailed from Port Glasgow as far as the Isles of Bute and Largs in the lower Clyde, where it reached its maximum “speed over ground” of 16.7 knots (19.2mph).

As for Glen Rosa, this newbuild is due to be launched in April but will not be completed until next year.

Glen Sannox will also require further work before its scheduled completion in late May. The ferry will undergo two months of testing by CalMac before being due to go into service on the main route to Brodick on Arran in late July or early August.

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.
