Second Delayed Ferry Glen Rosa Marks ‘Key Milestone’ as it Enters Dry Dock

A Clyde shipyard’s second of two dual-fuel ferries, which is massively delayed and over budget for CalMac’s route to Arran in southwest Scotland, has reached a “key milestone.”

The MV Glen Rosa, built by Ferguson Marine at Port Glasgow, has now been moved to a nearby dry dock at Dales Marine Services in Greenock.

The dry dock will allow the state-owned yard to make a significant step towards its completion, which will involve essential maintenance, repairs, and inspections of the new-build ferry.

A package of planned works to include rudder and stabilizer inspections, welding work to the bow clam doors, and painting repairs.

The 1,000-passenger Glen Rosa, powered by both liquefied natural gas (LNG) and marine diesel, which will serve the Arran route, is expected to remain in dry dock until August. At that time the 127 cars or 16 HGVs capacity ferry will return to Ferguson Marine.

The publicly owned Caledonian Maritime Assets is expected to hand over the 102m ferry in the second quarter of next year, following several delays.

Insider has further coverage of the new-build ferry, which follows its twin, Glen Sannox, which finally entered service in January, albeit seven years late. 

Afloat adds that the development comes just after Ferguson Marine announced that it has signed a contract with BAE Systems to build three structural components for the UK’s Royal Navy Type 26 frigate programme, which involves HMS Birmingham.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven't put up a paywall because we want to keep our marine journalism open.

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.
