Multipurpose corvettes for the Finnish Navy to be built at Rauma shipyard – order comprising four new corvettes brings RMC’s order book to over EUR 1 billion

Four new multipurpose corvettes for the Finnish Navy will be constructed at Rauma shipyard. The design phase will resume with immediate effect and construction of the first vessel will start at the shipyard in 2022. The Finnish Government approved the procurement, valued at approximately EUR 700 million, today, September 19, 2019. Rauma Marine Constructions Oy and the Finnish Defence Forces will formally sign the agreement for the construction of the multipurpose corvettes on September 26, 2019. CEO Jyrki Heinimaa is pleased that Rauma’s long traditions of building Finnish naval ships will continue.

Rauma Marine Constructions Oy and the Finnish Defence Forces have come to an agreement regarding the construction of the new fleet of four multipurpose corvettes for the Finnish Navy. The Squadron 2020 project will replace a large number of the Finnish Navy’s existent fleet, consisting of seven vessels. The Finnish Government approved the procurement contract today, September 19, 2019. The two parties will formally sign the construction agreement on September 26. The combat system, including weapons and sensors, will be provided by Saab, accompanied by necessary design and installation services by RMC.

The multipurpose corvettes will be delivered by 2026 and will be taken into operational use by the Finnish Navy in 2028. The procurement will have a considerable impact on employment, totalling around 3,600 person-years.

“This agreement is significant not only for its effect on local employment and businesses, but also on a national level, since at peak time, the project will employ some 1,000 people. Rauma Marine Constructions is a wholly Finnish-owned shipbuilding company, which continues the city of Rauma’s longstanding traditions of supplying combat vessels for the Finnish Defence Forces. Through this agreement, Finland will once again have a domestically built fleet, which supports our country’s security of supply”, says Jyrki Heinimaa, CEO, Rauma Marine Constructions.

Furthermore, according to Heinimaa, the project is also vital in strengthening the Finnish maritime industry and research conducted within the industry. RMC has, among other things, invested in production methods for light steel structures for the vessels and the agreement will also include new development and research projects.

“Projects such as Squadron 2020 enable new innovations and technology solutions to be utilised in a broader spectrum within Finnish shipbuilding”, adds Heinimaa.
Due to its strong order book, the shipyard is able to take a leading role in domestic maritime development projects. A good example is the ongoing construction of the new car and passenger ferry for Kvarken Link, which thanks to an array of innovative solutions, is the world’s first car and passenger ferry to be awarded the Clean Design certificate.

During the process of constructing the vessels, the shipyard will also develop the readiness to provide life-cycle services for the vessels following their delivery to the navy.

Ability to accommodate both combat vessels and civilian vessels

The Finnish Defence Forces is an important partner of RMC. In addition, the company’s order book of commercial civilian projects has also grown exponentially, and the company is profitable and has displayed strong growth. The agreement with the Finnish Defence Forces will bring RMC’s order book to over EUR 1 billion and create a positive impact on employment until the year 2026. The work will continue after the delivery as well, through the life-cycle services provided for the vessels.

Due to security reasons the corvettes and the commercial vessels will be built in separate locations at the shipyard. A new car and passenger ferry for the Vaasa-Uumaja route is currently under construction at the shipyard, as well as the planning of the Shuttle ferry for Tallink. RMC also announced its extended cooperation with the Meyer Turku shipyard. The cooperation has included construction blocks for cruise ships for the Turku-based shipyard and is now continuing, with RMC acquiring a licence to use the planning materials of the Shuttle’s sister ship, MS Megastar, from Meyer Turku. The materials will be used in planning the new ferry.

“Our shipyard is well equipped to handle the construction of both the civil and the governmental vessels simultaneously, which has also been successfully done in the past at Rauma shipyard. The Squadron 2020 project will naturally have its separate security arrangements and the construction is fully separated from the commercial civilian shipbuilding also through internal organisational arrangements”, notes Heinimaa.

As part of the project, the owners of RMC and the Finnish Defence Forces will also sign an agreement. The owners are committed to the project.
“We are happy that our owners have been behind this project since the beginning”, says Mikko Niini, chairman of the board at RMC.

Supply contracts signed for main equipment for Squadron 2020 project

Rauma Marine Constructions (RMC) has entered into three major supply contracts for the main equipment of Pohjanmaa Class multi-purpose corvettes commissioned by the Finnish Defence Forces. The main equipment will be purchased from leading global suppliers whose systems have been developed specifically for combat vessels. The contracts are worth over EUR 100 million in total.

The most crucial contracts for the supply of critical main equipment with long delivery times were signed during spring and summer in highly unusual circumstances. The coronavirus pandemic has posed significant challenges to numerous businesses, including the Squadron 2020 project.

– During these challenging times, we have had to develop new ways of working, also regarding the negotiations, which have demanded tenacity and patience from all parties involved. We are very pleased that the contracts for the most vital and time-sensitive equipment procurements for the Finnish Defence Forces’ Squadron 2020 project have now been signed. This is a considerable achievement, especially seeing as many shipyards and businesses have unfortunately had to close down completely, says Jyrki Heinimaa, President and CEO of Rauma Marine Constructions.

The most important machinery equipment in the multi-purpose corvettes are the gas turbine, the electric drive system along with the gear system that connects them to the propeller shafts, and the main diesel generators. The electric drive system and the gear system, which is critical to performance and technically challenging, will be supplied by the German company RENK AG. The company has decades of experience in delivering gear systems for combat vessels to nations around the globe.

The gas turbines will be supplied by General Electric. The LM2500 gas turbine is the world’s most commonly used gas turbine in naval ships. The Finnish Defence Forces will be the 39th navy in the world to adopt this turbine model.

The electrical power will be supplied by extremely quiet 12V 175D diesel generators from MAN Energy Solutions SE.

Several important factors were considered when selecting suppliers. These include the power/weight ratio of the engines and gear systems, reduced underwater noise, and warfighting vulnerability, which all play into the operative performance of the vessel. All systems also meet the demands of northern winter and ice-going conditions that are exceptional for warships. The engine and propulsion solution of the Squadron 2020 vessels is a so-called CODELAG (Combined Diesel Electric and Gas) system with two propeller shaft lines. When the ship travels at lower speeds, the vessel is driven by electrical engines, which connect to the gear and are powered by the diesel generators. At higher speeds and in heavy ice conditions, a high-power gas turbine is connected to the gear.

The systems and suppliers that were selected meet the criteria of national security of supply with which the vessels must comply. The vessels will be serviced in Finland throughout their lifecycle.
