Ice breaker Polaris in action.

- Polaris is a Finnish icebreaking vessel owned and operated by Arctia Ltd (a Finnish state-owned company). One of Finland's icebreaker ships, Polaris is the most powerful Finnish icebreaker ever constructed, as well as the world's first LNG-powered icebreaker.
The vessel (IMO number 9734161) is currently Finland-flagged (MMSI 230661000) and registered in Helsinki.
This is the world's first icebreaker equipped with dual-fuel engines. It runs on both LSMDO ("low-sulfur marine diesel oil") and LNG ("liquefied natural gas"), which lowers both emissions and operating costs.
Vessel's technical requirements and specifications were published in February 2013. Among those was the 16, 2 MW quad-screw engine - allowing navigation through compressive ridge fields at an average escort speed 9-11 Kkn (17-20 kph / 10-13 mph).
The ship's bollard pull (zero speed pulling capability) and propulsion are sufficient to allow a year-round operation even during winter months (ice thickness requirement 1,8 m / 6 ft). Among the specifications was also a maneuverability requirement - an ability for a 180-degree turn within a length of 220 m (520 ft) in just 3 minutes.
Designed primarily for Baltic Sea icebreaking and assisting services, the new Polaris icebreaker is also used in oil spill response operations due to the increasing oil shipping traffic in Baltic Sea the whole year-round. For this secondary purpose, the ship is fitted with special equipment for operations in both ice and open water and also for open-sea towing operations in strong wind and wave conditions.
Polaris vessel details and technology
The shipbuilder Arctech Helsinki Shipyard company was founded in 2011 and specializes in building icebreakers and other ice-going (mainly platform-supply and rescue) vessels. The company is a joint venture between STX Finland Cruise (now Meyer Turku Oy) and USC (United Shipbuilding Corporation, Russia). USC purchased 50% of Hietalahti Shipyard (aka Helsinki New Shipyard) in late 2010. In December 2014, USC bought the other 50% from STX Europe (now Chantiers de l'Atlantique) thus becoming the sole owner of the shipyard.
Instead of a helipad, the ship has a small bow-located winching area that can be used for helicopter landing in cases of emergency.
The vessel is PC4/Polar Class 4 intended for year-round operations in thick first-year ice. The class also signifies the ship can be operated as an escort ice-breaker in difficult ice conditions.
The hull features structural strengthening in several critical areas.
As an oil spill response ship, Polaris has an installed advancing system and also stern-mounted brush skimmers and recovery tanks (total capacity 1300 m3 / 46000 ft3).
The powerplant is positioned midship (main deck level), consisting of all four (2 pairs) Wartsila four-stroke dual-fuel generator sets (medium-speed engines) fitted with exhaust gas economizers. An auxiliary engine is used for producing electricity when the vessel is at the port. The electrical power plant's combined output is 22,5 MW. The ship also has an additional emergency diesel generator.
Polaris is capable to open a uniform ice-free channel 25 m (82 ft) wide through ice field with thickness 1,8 (6 ft) at 4 Kn speed (7,4 kph / 4,6 mph). The icebreaker can also maintain 9,2 Kn (17 kph / 11 mph) speed in unbroken ice fields with thickness 0,9 m (3 ft). These specifications allow the ship to maintain a high escort speed in winter ice conditions.
The Polaris icebreaker's projected lifetime (service life) is 50 years.
The list of other Finnish icebreakers also includes (in brackets - year built): MSV Fennica (1993), MSV Nordica (1994), Kontio (1987), Otso (1986), Sampo (1960), Sisu (1976), Urho (1975).
In late November 2014, Finland's "Cabinet Committee on Economic Policy" released an official statement regarding the country's aging icebreaking fleet. According to the statement, Arctia Shipping's old fleet would be fully replaced with new icebreakers by the year 2029. The project's overall cost is approx EURO 1 billion. The new vessels (like Polaris) must be multipurpose icebreakers (including for Arctic oil explorations).
The vessel has 1 dining room, Sauna, no swimming pool, no elevator, no helipad (helicopter deck).
Max Draught: 9 m (30 ft)
DWT Deadweight tonnage: 3000 tons
Displacement tonnage: 5880 tons
Bollard pull (emergency towing capacity) 193 tons
Ice-breaking capacity: 1,2 m (4 ft) at speed 6 kn / 7 mph / 11 kph
Ice-breaking capacity: 1,8 m (4 ft) at speed 3,5 kn / 4 mph / 6,5 kph
Endurance: 10 days (LNG), 20 days (LSMDO)
Powerplant: 2x Wartsila 9L34DF diesel engines (each 4,5 MW power output), 2x Wartsila 12V34DF diesel engines (each 6 MW output), 1x Wartsila 8L20DF (auxiliary engine, 1,4 MW output)
Propulsion: Diesel-electric, 3x azimuth thrusters (ABB Azipod motors), power outputs - 1x bow (6 MW), 2x stern (each 6,5 MW), no pitch propellers. Total propulsion power output is 19 MW (25000 hp).
Its a wonderful experience to see a heavy tugboat ice breaker. I could imagine how cold it is over there
Laking tulong ni Polaris ice breaker s mga na istranded s yelo s karagatan

Nice to see some old colleagues at work. I worked Arctia ice breakers. Saddly i got medical problems and i wasnt allowed to work at sea anymore 🥲
oh sad to hear that part but i think you have a good vacation fight now. What name of the Ice breaker you have been?
@@loyaltyfam5060 Sisu and Nordica... same company as videos ship has. Its state owned company.
Polaris was brand new when i worked at Arctia. I still miss those times when i worked at sea. It still brakes my heart and mind to remember that moment when doctor camed to my hospital bed and said the diagnose i didnt want it to be (my diagnose doesnt allow any kind of work at sea).
yes i know them because my vessels route is only there in pietarsaari and oulu. I always meet them every year
Ice breaker are very interesting ship i think they have a very advance equipment in monitoring the ice.
If you like icebreaker themed videos, you may be interested to watch videos from 'Tero Savolainen MTB' channel, just amazing clips from a sea near me.
Thank you for sharing your experience po and keep safe always po
O Wow! Super lamig dyan! Ingats kabayan 🇵🇭❤
