Turva is a Finnish offshore patrol vessel. Built in 2014 by STX Finland Rauma shipyard for the Finnish Border Guard, she is the largest vessel of the fleet as well as the first patrol vessel in Finland powered by liquefied natural gas (LNG).
Development and construction
In the second supplemental budget of 2009, the Government of Finland reserved 57 million euro for the procurement of a new offshore patrol vessel for the Finnish Border Guard.[http://valtioneuvosto.fi/ajankohtaista/tiedotteet/tiedote/fi.jsp?oid=270351&c=0&toid=2213&moid=2216 Sisäasiainministeri Anne Holmlund: Lähivuosina panostetaan erityisesti Itämeren turvallisuuteen ja merellisen ympäristön suojeluun]. Sisäasianministeriö, 15 September 2009. {{retrieved|accessdate=2013-07-21}} In addition, a further 10.4 million euro was reserved for the design and development of the new vessel in 2009–2010. However, it was found out that the allocated funds would not be enough to purchase a vessel that would fulfill the requirements, so in the third supplemental budget of 2011 the funding was increased by 70 percent, bringing the price of the vessel to 97 million euro and making her the most expensive patrol vessel ever constructed in Finland.[https://www.ts.fi/uutiset/280788 Uusi ulkovartiolaiva on kallein vartioalus koskaan].

R.I.N.A. Symposium on Small Fast Warships and Security Vessels, London, 18–21 May 1982, Paper No.22. The construction of the new offshore patrol vessel was slightly delayed and Turva began her first sea trials on 25 February 2014. About a month later, on 21 March, the vessel left for the second sea trials. Turva was completed and handed over to the Finnish Border Guard on 9 May 2014.[http://www.aamulehti.fi/Kotimaa/1194900107176/artikkeli/ulkovartiolaiva+turva+luovutettiin+rajavartiolaitokselle.html Ulkovartiolaiva Turva luovutettiin Rajavartiolaitokselle].

The old vessels were not strengthened for navigation in ice and their oil spill prevention and response capability was not deemed adequate for dealing with the increased traffic in the Gulf of Finland.
On 16 September 2013, STX Finland decided to close the shipyard in June 2014 and for a while it looked like Turva would be the last new vessel built in Rauma where ships have been constructed for over 300 years.[http://yle.fi/uutiset/musta_maanantai_stxn_rauman_telakka_lopetetaan/6832688 Musta maanantai: STX:n Rauman telakka lopetetaan].

In December 2020, the Finnish Government authorized the Border Guard to order two new offshore patrol vessels. The new vessels will be similar in size to Turva and enter service by 2025.{{cite web|url=http://www.lentoposti.fi/uutiset/rajavartiolaitos_hankkii_kaksi_uutta_turva_luokan_monitoimialusta_eduskunnalta_tilausvaltuudet|title=Rajavartiolaitos hankkii kaksi uutta Turva-luokan monitoimialusta - eduskunnalta tilausvaltuudet|language=fi|publisher=Lentoposti|date=11 December 2020|accessdate=12 December 2020}} On 16 August 2021, the Border Guard signed a letter of intent with Meyer Turku for the construction of the new vessels.{{cite web|url=https://yle.fi/uutiset/3-12060054|title=Meyer Turun telakka rakentaa Rajavartiolaitokselle monitoimialuksia|language=fi|publisher=YLE|date=16 August 2021|accessdate=16 August 2021}}
Design
= General characteristics =
Turva is {{convert|95.9|m|ft|0}} long and {{convert|17.4|m|ft|0}} wide, making her the largest vessel ever commissioned by the Finnish Border Guard as well as longer than any existing or past vessel commissioned by the Finnish Navy. Fully laden, she draws {{convert|5|m|ft|0}} of water. At design draught, the vessel has a deadweight tonnage of 660 tonnes while her maximum deadweight is around 1,800 tonnes. Her complement will be approximately 30.
The main purposes of the new offshore patrol vessel are open sea patrol and ensuring border safety. Turva carries a rigid-hulled inflatable boat and a larger patrol boat, both stowed in covered recesses, that can be used to carry a vessel inspection teams to intercepted ships. While the vessel does not have a hangar, the forward helipad with folding "wings" is large enough for receiving and refueling a Eurocopter AS332 Super Puma, the largest type of helicopter operated by the Finnish Border Guard, during search-and-rescue operations at sea. Turva is the first Finnish patrol vessel fitted with such capability. For surveillance, Turva has a Cassidian TRS-3D radar—the same used in the Hamina-class missile boats and Hämeenmaa-class minelayers of the Finnish Navy—and extensive command and control systems which allow the ship to direct large rescue operations both in the air and on the surface.[http://www.lentoposti.fi/uutiset/perjantaina_nimen_saanut_rajan_ulkovartiolaiva_turva_on_kopteritukialus Perjantaina nimen saanut Rajan ulkovartiolaiva Turva on kopteritukialus].

Rajavartiolaitos, 19 July 2013. {{retrieved|accessdate=2013-08-03}} Although no details have been released, the vessel is also fitted with underwater surveillance systems.
Turva is also equipped for rescue operations, firefighting, emergency towing and demanding environmental duties. She can perform mechanical recovery of spilled oil with built-in recovery systems in open water, either by using conventional outriggers and booms in calm seas or a stiff steel boom and a special wave-dampening channel in heavy weather. The oil recovery system has been manufactured by the Finnish company Mobimar which has also provided equipment for other Finnish patrol vessels. Furthermore, the vessel is also fitted for but not with equipment capable of recovering oil in ice conditions. The internal storage tanks are dimensioned for {{convert|1000|m3|cuft}} of recovered oil and {{convert|200|m3|cuft}} of recovered chemicals.[http://www.ymparisto.fi/default.asp?contentid=111988 Valtion öljyntorjunta-alukset].

Rajavartiolaitos, 11 December 2013. {{retrieved|accessdate=2013-12-22}} For diving support and oil recovery tasks, Turva carries a small workboat.[http://www.raja.fi/uvl10/seuraa_laivan_valmistumista/1/1/vko_40_tyovene_tuli_norjasta Vko 40: Työvene tuli Norjasta].

Like all Finnish offshore patrol vessels, Turva can be armed and used for national defense purposes in a crisis. However, during peacetime the vessels carry only small arms.
The blue-and-white colouring, inspired by the flag of Finland, is a departure from the traditional green hull utilized by Finnish Border Guard. Following the construction of Turva, it became the standard for all Finnish patrol vessels.
= Power and propulsion =
Turva is powered by three environmentally friendly Wärtsilä 34DF series dual-fuel engines capable of burning both diesel fuel as well as liquified natural gas (LNG). For redundancy and safe return to port, the engines are arranged in two independent engine rooms divided by a watertight bulkhead. In the aft engine room, a 12-cylinder Wärtsilä 12V34DF producing {{convert|6400|kW|hp|abbr=on}} is mechanically coupled to a controllable-pitch propeller. In the forward engine room, two 6-cylinder 6L34DF generating sets with an output of {{convert|3000|kW|hp|abbr=on}} each produce power for two electrically driven Rolls-Royce Azipull AZP120CP Z-drive azimuth thrusters. If the forward engine room is damaged, the shaft generator coupled to the bigger engine can be used to produce electricity for the azimuth thrusters, which are required for steering the vessel as she has no separate rudders, and other onboard systems.Monikäyttöinen Turva. [http://www.sanomapaino.fi/DIGIJULKAISU/Reservilainen_66_2013/index.html#/14/ Reserviläinen 6/2013, page 14]. Since the azimuth thrusters are powered by electric motors and the centerline shaft is mechanically coupled to the main engine, the propulsion system as a whole could be referred to as "combined diesel-electric and diesel" (CODLAD). Turva is the first ship fitted with this type of propulsion arrangement—two azimuth thrusters and a centerline shaft—which was originally developed for icebreakers and icegoing LNG carriers.Niini, M. (2013): [http://www.akerarctic.fi/02_Niini_1.pdf Last year's achievements and the way ahead]. Aker Arctic Technology. {{retrieved|accessdate=2013-07-21}} For maneuvering and DP2 class dynamic positioning, the ship has a transverse bow thruster and a retractable azimuth thruster in the bow.[http://www.raja.fi/uvl10/seuraa_laivan_valmistumista/1/1/vko_30_potkurille_lavat Vko 30: Potkurille lavat]. Rajavartiolaitos, 24 July 2013. {{retrieved|accessdate=2013-07-26}}
Turva is the first LNG-powered offshore patrol vessel as well as only the second LNG-powered ship (after Viking Grace) to enter service in Finland. Unlike in the ferry, which has two deck-mounted LNG storage tanks, the single fuel tank in Turva is built inside the vessel.[http://www.raja.fi/uvl10/seuraa_laivan_valmistumista/1/1/vko_19_lohkoja_varustellaan_44313 Vko 19: Lohkoja varustellaan]. Rajavartiolaitos, 4 June 2013. {{retrieved|accessdate=2014-04-12}}
The service speed of the vessel will be {{convert|18|kn}} and despite her bulbous bow she will also be capable of breaking level ice up to {{convert|80|cm}} in thickness. With a bollard pull of approximately 100 tonnes, Turva is capable of towing even the largest tankers regularly sailing in the Baltic Sea.
