Transcript of NB 508 Baltika - .NB 508 Baltika NB 508 Baltika is an innovative multipurpose icebreaking emergency


  • NB 508 BaltikaNB 508 Baltika is an innovative multipurpose icebreaking emergency and rescue vessel built by Arctech Helsinki Shipyard for the Russian Federal Agency of Sea and River Transport. The ship will be operating in the Gulf of Finland.

    Baltika uses cutting-edge oil spill response technology and represents a significant investment in the safety of the Gulf of Finland. Thanks to its versatility, Baltika will be able to meet the ever growing challenges in the Gulf of Fin-land with its state-of-the-art equipment as far as icebreaking, rescue and oil spill combat missions are concerned. Baltika is also the first vessel in the world that breaks ice obliquely, creating a very wide channel.

    Icebreaking featuresAhead and astern: transit in level ice up to 1 m. Oblique mode: possible directions from 0-180 degrees without limitations, channel width up to 50 m.

    Oil transportation in the Gulf of Finland through main oil ports

    Vessel sizes and transportation volumes in the Gulf of Finland have undergone a marked growth in recent years. Along with this growth increases also the risk of accidents and oil disasters. Baltika is capable of breaking a chan-nel in ice that would normally require two icebreakers.

    The vessel has a patented asymmetric hull and three azimuth thrusters which allow the vessel to operate efficiently ahead, astern and obliquely (sideways). In the oblique mode, the vessel is able to create a 50-metre-wide channel in ice that is 0.6 metres thick and to recover oil from the sea both in open-water and ice conditions. When moving ahead or astern, the ship is able to proceed in ice that is one metre thick. Thanks to its good maneuverability, the vessel is suitable for icebreaking duties in harbours.

    The blocks of Baltika were built at Shipyard Yan-tar JSC in Kaliningrad. The hull assembly and the outfitting and finalisation of the vessel were carried out by Arctech in Helsinki. The vessel was launched in December 2013 and delivered to the customer in spring 2014. Baltikas home port is the oil harbour of St. Petersburg, Russia.

  • From idea to ship

    An internal innovation competition at Masa-Yards* Arctic Research Center (now Aker Arctic*) gave rise to an idea of an icebreaker which could operate both ahead and astern as well as sideways. The idea was put to test using a conventional icebreaker which was towed obliquely. Results from power requirement tests were encouraging and the first hull shape, triangular, was developed to-wards the end of 1996.The first two years of testing at Aker Arctic focused on the icebreaking properties of the vessel. Open-water tests in 1999 showed that a triangular hull works well in ice but the ships behaviour in rough seas was not satisfactory. Development work on the hull continued with improvements on the open-water properties, however, without compromising the icebreaking capability. Testing was carried out meticulously in several stages, which took years to complete.

    In 2002, an idea was conceived to build an obliquely-operable asymmetric vessel that could be used for both icebreaking and oil spill combat and sea rescue missions. At the same time, an inven-tion related to oil spill combatting technology was patented. The Finnish Environment Institute joined the project.

    Russias oil transports in the Gulf of Finland started in the early 1990s. Increased tanker traffic meant that more icebreaking capacity was also needed. With the existing fleet, it took two icebreakers to assist one big oil tanker. It was realised that an agile icebreaker, capable of creating both wide and narrow channels, was needed. Aker Arctic took the challenge and created a concept for an obliquely-operable icebreaker.

    In May 2010 a Memorandum of Understanding (MoU) was signed for further development of the idea to a real ship. This event was vitnessed by the Prime Ministers of both Russia and Finland, Vladimir Putin and Matti Vanhanen. This illustrates the strong collaboration in the Gulf of Finland region between the two counties.On the basis of the MoU, Aker Arctic started to design and test the vessel in order to make it meet the re-quirements of the purchaser. The shipbuilding contract between the Russian Federal Agency of Sea and River Transport and Shipyard Yantar JSC was signed in October 2011, after which Yantar and Arctech Helsinki Shipyard Inc. signed the final contract for the design and construction of the vessel.

    The first oblique icebreaker in the world was successfully final-ised at Arctech Helsinki Shipyard in spring 2014.

    Christian Wennerstrand served as Captain of NB 508 Baltika during the vessels first sea trials in the archipelago of Helsinki.

    We entered the bearing, speed and degree of lateral movement onto the ships computer. Then we just pressed Enter, and the ship started moving according to the input values. On open water, Balti-ka, steered by the autopilot, ran straight and responded to the auto-pilot commands impeccably. On heavy swell, the ship behaved well thanks to the antiroll tanks.

    Steered manually, Baltika is a bit more challenging because of the hull shape and the positioning of the propulsion units. When in harbour, you had to be very careful, as the ship easily turns around its axis.

    Propulsors and maneuverabilityThe three azimuth thrusters that can be rotated 360 degrees give the vessel excellent maneuverability. One of the propulsors is at the bow and two at the stern. The asymmetrically positioned propulsors give the vessel its ability to move sideways.

    Baltika can be steered either manually or by an autopilot. When the ship is being steered manually, its direction and posi-tion are maintained with the help of control equipment. The ship includes an advanced dynamic positioning system, which assists the crew to steer, navigate and keep the ship still even in rough seas.

    The propulsors are powerful, and when you begin to decelerate and stop the vessel at high speed, you can easily lose control of the ship if you are not careful.

    Once you learn how to handle it, Baltika is a very agile ship. For its shape alone, it is a special and technically versatile vessel. Another thing which makes is special, is the fact that it was the first ship to break ice while moving sideways. The ship is so good that I would be gladly willing to work on it myself.

  • Efficient oil recoveryBaltika includes an advanced oil recovery system.

    The ship is equipped with a built-in brush system designed to separate oil from water. The ships straight side functions effectively as a sweep arm which guides the oily water into the ship through a hatch on the side. The oil is recovered in tanks and the cleaned water is pumped back into the sea. The theoretical collecting capacity of Baltika on open water is about 550 cubic metres per hour at the speed of one knot at a 30 oblique angle when the oil film is 10 mm thick.
