VIDEO: Finnish ‘Louhi’ and ‘Turva’ on full scale ice trials
- Equipment & technology
A video released by Aker Arctic shows two Finnish vessels, the navy’s multipurpose vessel Louhi and the Finnish Border Guard offshore patrol vessel Turva, carrying out full scale ice trials during the winter of 2016.
Drone footage shows the vessels performing astern ridge penetration tests and level ice performance trials in the Gulf of Bothnia, Finland.
FNS Louhi was built by Uki Workboat Ltd. in 2011. She is a multipurpose oil and chemical spill response vessel owned by the Finnish Environment Institute (SYKE), but manned and operated by the Finnish Navy.
The 3,450-ton vessel has a diesel-electric power plant and propulsion system with four Wärtsilä 9L20 diesel engines producing electricity for two 2.7 MW Rolls-Royce Z-drive thrusters.
At 71.4 meters, Louhi is designed to operate in all Baltic Sea ice conditions and fitted with mechanical oil spill response outfit, including equipment designed specifically for collecting spilled oil in ice conditions.
OPV Turva, delivered in 2014 from STX Rauma shipyard, is one of the world’s first LNG-powered offshore patrol vessels. At 95.9 m, she is the largest vessel in the Finnish Border Guard fleet.
The propulsion system consists of one controllable pitch propeller mechanically driven by a medium-speed Wärtsilä 12V34DF dual fuel engine, two Wärtsilä 6L34DF dual fuel generating sets, and two Rolls-Royce Azipull Z-drive thrusters driven by electric motors.
Turva is fitted with mechanical oil recovery systems, extensive command and control outfit including a Cassidian TRS-3D radar, and a helideck capable of receiving and refueling Super Puma helicopters both on deck and while hovering. Despite having a bulbous bow, Turva can also operate in ice-covered waters.
