Kvarken Link
Kvarken ( sv, Kvarken, Norra Kvarken (as opposed to South Kvarken); ) is the narrow region of the Gulf of Bothnia separating the Bothnian Bay (the inner part of the gulf) from the Bothnian Sea. The distance from the Swedish mainland to the Finnish mainland is around , while the distance between the outermost islands is only . The water depth in the Kvarken region is only around . The region also has an unusual rate of land rising at almost a year. Several attempts to cross the strait swimming have been made, but cold water and currents have usually been insurmountable obstacles. The first successful crossing was carried out by Lennart Flygare, Pavio Grzelewski and Tore Klingberg, who on 24 July, 2018, swam from Valassaaret ( Valsörarna) on the Finnish side to Holmöarna in Sweden. It took them 12 hours 2 minutes to cross the strait. Kvarken Archipelago On the Finnish side of Kvarken, there is a large archipelago, the Kvarken Archipelago, which includes the large islands ...

Finnish-Swedish Ice Class
Finnish-Swedish ice class is an ice class assigned to a vessel operating in first-year ice in the Baltic Sea and calling at Finnish or Swedish ports. Ships are divided into six ice classes based on requirements for hull structural design, engine output and performance in ice according to the regulations issued by the Finnish Transport and Communications Agency (Traficom) and the Swedish Maritime Administration. Purpose During the winter months, Finnish and Swedish authorities may declare traffic restrictions in the Northern Baltic Sea in order to ensure that ships operating in the region are capable of navigating in ice-covered waters safely and efficiently. These restrictions, for example "ice class 1A, 2000 DWT", declare the minimum ice class and other requirements for ships that may be provided with icebreaker assistance. The Finnish fairway dues, a system of fees charged for the use of sea lanes to cover the costs of management and icebreaker assistance, also depend ...

Biogas
Biogas is a mixture of gases, primarily consisting of methane, carbon dioxide and hydrogen sulphide, produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste and food waste. It is a renewable energy source. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogen inside an anaerobic digester, biodigester or a bioreactor. Biogas is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide () can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed after removal of carbon dioxide and hydrogen sulphide, the same way as natural gas is compressed to CN ...

Liquefied Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around (gauge pressure), which is about one-fourth times atmospheric pressure at sea level. The gas extracted from underground hydrocarbon deposits contains a varying mix of hy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roll-on/roll-off
Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter. This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane to load and unload cargo. RORO vessels have either built-in or shore-based ramps or ferry slips that allow the cargo to be efficiently rolled on and off the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps, the term RORO is generally reserved for large oceangoing vessels. The ramps and doors may be located in the stern, bow, or sides, or any combination thereof. Description Types of RORO vessels include ferries, cruiseferries, cargo ships, barges, and RoRo service for air deliveries. New automobiles that are transported by ...

Azipod
Azipod is a trademark azimuth thruster pod design, a marine propulsion unit consisting of a fixed pitch propeller mounted on a steerable gondola ("pod") containing the electric motor driving the propeller, allowing ships to be more maneuverable. They were developed in Finland jointly by the shipbuilding company Masa-Yards and the ABB Group, which produces them. Although "Azipod" is a registered brand name, it is sometimes used incorrectly as a generic trademark for podded propulsion units manufactured by other companies. Concept In the conventional azimuth thrusters such as Z-drive and L-drive thrusters, the propeller is driven by an electric motor or a diesel engine inside the ship's hull. The propeller is coupled to the prime mover with shafts and bevel gears that allow rotating the propeller about a vertical axis. This type of propulsion system has a long tradition throughout the 1990s and today such propulsion units are produced by a number of companies around the wor ...

Wasa Line
Wasaline, previously Oy Vaasa-Umeå Ab (1948–1965), Vaasa-Umeå AB (1965–1979), Oy Vaasanlaivat – Vasabåtarna Ab (1979–1991) and Wasa Line (1991–1993) are different names for the Finnish List of ship companies, shipping company that ceased trading in 1993 when it merged into Silja Line. Since 2013 the name is being used by a new company that operates between Vaasa (homebase) and Umeå. History In 1948, ''Rederi Ab Vasa-Umeå'' was founded to start passenger traffic across Kvarken, the narrowest part of the Gulf of Bothnia. On 28 May, the company's first ship MS Turisten, MS ''Turisten'' made its first journey from Vaasa in Finland to Umeå in Sweden. People living on both sides of Kvarken are predominantly Swedish-speaking, as were the company founders, hence the company originally only had a name in Swedish and ships were named in Swedish. The company's first ships were used steamboat, steamers, only capable of summer traffic. In 1958, Merivienti Oy, subsidiary of t ...

Rauma, Finland
Rauma (; sv, Raumo) is a town and municipality of around () inhabitants on the west coast of Finland, north of Turku, and south of Pori. Its neighbouring municipalities are Eura, Eurajoki, Laitila and Pyhäranta. Granted town privileges on 17 April 1442 (then under the rule of Sweden), Rauma is known for its paper and maritime industry, high quality lace (since the 18th century) and the old wooden architecture of the city centre (Old Rauma, Vanha Rauma), which is a UNESCO World Heritage site. History In the 14th century, before it was declared a town, Rauma had a Franciscan monastery and a Catholic church. In 1550, the townsmen of Rauma were ordered to relocate to Helsinki, but this was unsuccessful and Rauma continued to grow. Practically the whole wooden part of the town of Rauma was devastated in the fires of 1640 and 1682. The city centre, which was as large as the town was until 1809, has approximately 600 wooden buildings. The neo-renaissance style of many of the house ...
