Car and passenger ferry Hammershus

Construction of Rauma Marine Constructions’ first newbuilding vessel, a car and passenger ferry named Hammershus for Danish shipping company Molslinjen, was completed in summer 2018 at the Rauma shipyard.

The 158-meter long and 23.5 meter wide ferry started operating in autumn 2018. The ship’s passenger capacity is 720, along with 20 crew members. The vessel can carry some 90 full-trailer trucks of cargo. Its main cargo is trucks, but the ferry can transport hundreds of personal cars if necessary.

The car and passenger ferry can travel up to 17.7 knots and it runs on sulphur-free fuel. The vessel also consumes significantly less fuel compared to previous vessels. This was made possible by the fuel efficient Wärtsilä main engines, as well as the shape of the hull. In addition, the vessel complies with all current and upcoming environmental regulations.

The primary operating route of the ferry is between Køge, Zealand and Rønne, Bornholm, but the ferry will see use for a period of the year on the route between Rønne and Sassnitz in Germany.

The ship was constructed in Rauma in full, and its impact on employment totaled around 1,000 person-years.

General overhaul of research vessel Aranda

A general overhaul of the Finnish Environment Institute research vessel Aranda began at the Rauma shipyard in summer 2017. Aranda was delivered to its owner during summer 2018.

With repairs and modernisation, Aranda is set to remain in operation until the 2030s. The overhaul included the addition of a new block in the central section, and the ship’s aft and afterdeck were redesigned. In total, the vessel was extended seven meters. Thanks to the additional length, Aranda’s research and laboratory facilities could be expanded and the vessel was able to switch to a fully electrical transmission in order to meet new requirements for research.

As a result of the overhaul, Aranda’s operations are more environmentally friendly since it is able to run on biodiesel fuel all year round and make short trips with just battery power. The new battery technology lowers emissions and significantly reduces noise pollution, which greatly helps the study of marine biology.

Conversion of icebreaker Otso

The extensive conversion work for Arctia icebreaker Otso was carried out at the RMC shipyard during early summer 2015. In the project, Otso was converted to a specialised vessel capable of more versatile tasks.

The ship was fitted with a roll stabilisation tank to enable open water navigation. The conversion also reinforced the ship’s structures in order to upgrade its ice class to match Arctic requirements.

In addition to this, the hull was reinforced and the vessel was fitted with new lifeboats and helicopter deck that meet international standards.

Originally designed for the Baltic Sea, the converted Otso can now operate anywhere in the world. The three-month-long conversion project employed tens of people in Rauma.

Maintenance of multi-purpose icebreakers Fennica and Nordica

Rauma Marine Constructions has an agreement with Arctia Oy on the maintenance of the multi-purpose vessels Nordica and Fennica. The first round of maintenance work by RMC took place in early 2015.

Some fifty metalwork, surface treatment and electrical installation professionals from Rauma Marine Construction’s network of partners worked on the icebreakers.

Both multi-purpose vessels have strong ties to Rauma. Fennica was launched from the Aker Finnyards shipyard in Rauma in 1993, and its sister ship Nordica one year later.

Modernisation of Tallink Silja Serenade and Symphony

In autumn 2015, Rauma Marine Constructions carried out modernisation of the ferry m/s Silja Serenade, which operates between Helsinki and Stockholm. The project included both surface renovations visible to passengers and technical upgrades.

The ship’s bottom was repaired, its steering system was upgraded, and one of the main engines was fully serviced. Extensive overhaul was also carried out for the seventh deck, and all 60 deluxe cabins on board were fully modernised during the two-week dry docking.

Modernisation for Silja Symphony took place in early 2016. The vessel received somewhat similar alterations to its sister ship, Silja Serenade. All family cabins on Symphony were modernised, and deluxe cabins were redecorated. As with Serenade, the conference area lobby was also renovated.

In addition to this, the Old Port Pub in the ship’s aft received new surfaces and furnishings, and a new entrance to the pub and concert stage was constructed on the Promenade.
