Finnish Icebreaker Nordica (1994)
MSV ''Nordica'' is a Finnish multipurpose icebreaker and offshore support vessel. Built in 1994 by Finnyards in Rauma, Finland, and operated by Arctia Offshore, she and her sister ship ''Fennica'' were the first Finnish icebreakers designed to be used as escort icebreakers in the Baltic Sea during the winter months and in offshore construction projects during the open water season. When ''Botnica'' was sold to Port of Tallinn in 2012, ''Nordica'' became again the newest icebreaker in service in Finland until the delivery of the new icebreaker, ''Polaris'', in 2016. Design General characteristics The maximum overall length of ''Nordica'' is and her length between perpendiculars is . The hull has a moulded breadth of and depth of .

Finland
Finland ( fi, Suomi ; sv, Finland ), officially the Republic of Finland (; ), is a Nordic country in Northern Europe. It shares land borders with Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland across Estonia to the south. Finland covers an area of with a population of 5.6 million. Helsinki is the capital and largest city, forming a larger metropolitan area with the neighbouring cities of Espoo, Kauniainen, and Vantaa. The vast majority of the population are ethnic Finns. Finnish, alongside Swedish, are the official languages. Swedish is the native language of 5.2% of the population. Finland's climate varies from humid continental in the south to the boreal in the north. The land cover is primarily a boreal forest biome, with more than 180,000 recorded lakes. Finland was first inhabited around 9000 BC after the Last Glacial Period. The Stone Age introduced several differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage). Deadweight tonnage was historically expressed in long tonsOne long ton (LT) is but is now usually given internationally in t ...

Gross Tonnage
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or Displacement (ship), displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces.

Moulded Breadth
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft.

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition.

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Polaris (icebreaker)
''Polaris'' is a Finnish icebreaker. Built in 2016 by Arctech Helsinki Shipyard, she is the most powerful icebreaker ever to fly the Finnish flag and the first icebreaker in the world to feature environmentally friendly dual-fuel engines capable of using both low-sulfur marine diesel oil (LSMDO) and liquefied natural gas (LNG). ''Polaris'' was initially ordered by the Finnish Transport Agency, but the ownership was transferred to the state-owned icebreaker operator Arctia after delivery. Background While the history of winter navigation in Finland dates back to the strengthened sleigh-boats used to carry mail from Finland to Sweden in the 17th century, the annual "ice blockade" that closed the Finnish ports for the winter months and stopped nearly all foreign trade was not broken until 1890 when the Finnish Board of Navigation commissioned one of the first purpose-built icebreakers in the world. Despite her shortcomings, ''Murtaja'' proved that year-round shipping was possible in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Tallinn
Port of Tallinn ( et, Tallinna Sadam) is the biggest port authority in Estonia. Taking into account both cargo and passenger traffic, it is one of the largest port enterprises of the Baltic Sea. Port of Tallinn is a publicly listed company managing five constituent ports (two of them in Tallinn): * Tallinn Passenger Port / Old City Harbour (''Vanasadam'') – the main passenger harbour in Estonia; located in the centre of Tallinn; one of the busiest passenger ports of the Baltic Sea *Muuga Harbour – the largest cargo harbour in Estonia, located in Maardu, 13 km northeast of Tallinn city centre *Paldiski South Harbour – a cargo harbour in Paldiski, 40 km west from Tallinn *Paljassaare Harbour – a small cargo harbour a few kilometres northwest of Tallinn city centre in Paljassaare *Saaremaa Harbour – a passenger harbour on the island of Saaremaa, in Ninase In October 2016, the Port of Tallinn subsidiary TS Laevad took over operation of the ferry routes between the ...

MSV Botnica
MSV ''Botnica'' is a multipurpose offshore support vessel and icebreaker built by Finnyards in Rauma, Finland, in 1998. She was the newest and technically most advanced state-owned icebreaker of Finland until 2012, when she was sold to the Port of Tallinn for 50 million euro. ''Botnica'' is used as an escort icebreaker in the Baltic Sea during the winter months, but carries out subsea and offshore construction works worldwide during the open water season. Design General characteristics The maximum overall length of ''Botnica'' is and her length between perpendiculars is . The hull has a moulded breadth of and depth of . The draught is when the ship is acting as an icebreaker and in offshore supply operations. The gross tonnage of ''Botnica'' is 6,370, net tonnage 1,911 and deadweight tonnage 2,890 tons. The light displacement of ''Botnica'', i.e. the weight of the ship without consumables, cargo and crew, is 5,880 tons. Her loaded displacement varies according to the l ...

Offshore Drilling
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas. Offshore drilling presents environmental challenges, both offshore and onshore from the produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing US offshore drilling debate. There are many different types of facilities from which offshore drilling operations take place. These include bottom founded drilling rigs ( jackup barges and swamp barges), combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units (MODU) including semi-submersibles or drillships.
