Ægir
Ægir (anglicised as Aegir; Old Norse 'sea'), Hlér (Old Norse 'sea'), or Gymir (Old Norse less clearly 'sea, engulfer'), is a jötunn and a personification of the sea in Norse mythology. In the Old Norse record, Ægir hosts the gods in his halls and is associated with brewing ale. Ægir is attested as married to a goddess, Rán, who also personifies the sea, and together the two produced daughters who personify waves, the Nine Daughters of Ægir and Rán, and Ægir's son is Snær, personified snow. Ægir may also be the father of the beautiful jötunn Gerðr, wife of the god Freyr, or these may be two separate figures who share the same name (see below and Gymir (father of Gerðr)). One of Ægir's names, ''Hlér'', is the namesake of the island Læsø (Old Norse ''Hléysey'' 'Hlér's island') and perhaps also Lejre in Denmark. Scholars have long analyzed Ægir's role in the Old Norse corpus, and the concept of the figure has had some influence in modern popular culture. ...

Heerema Marine Contractors
Heerema Marine Contractors (HMC) is a contractor headquartered in the Netherlands most notable for operation of three of the largest crane vessels in the offshore industry. History Heerema Marine Contractors was formed in 1948 by Pieter Schelte Heerema as a small construction company providing oilfield platforms in Venezuela. In the 1960s the company focused on the North Sea offshore developments. The company developed crane vessels to lift large offshore platforms and modules. The ship shaped crane vessel ''Challenger'' was equipped to lift 800 t. The need for large stable crane vessels to operate in the North Sea environment lead the company to develop the first large semi-submersible crane vessels. In 1978, HMC commissioned Mitsui to construct the two sister semi-submersible crane vessels, and SSCV ''Hermod''. These vessels could lift 5,400 tonnes with the twin cranes, and were later upgraded to 8,200 tonnes. In 1988 HMC formed a joint venture with McDermott called HeereM ...

Panama City
Panama City ( es, Ciudad de Panamá, links=no; ), also known as Panama (or Panamá in Spanish), is the capital and largest city of Panama. It has an urban population of 880,691, with over 1.5 million in its metropolitan area. The city is located at the Pacific entrance of the Panama Canal, in the province of Panama. The city is the political and administrative center of the country, as well as a hub for banking and commerce. The city of Panama was founded on 15 August 1519, by Spanish conquistador Pedro Arias Dávila. The city was the starting point for expeditions that conquered the Inca Empire in Peru. It was a stopover point on one of the most important trade routes in the American continent, leading to the fairs of Nombre de Dios and Portobelo, through which passed most of the gold and silver that Spain mined from the Americas. On 28 January 1671, the original city was destroyed by a fire when the privateer Henry Morgan sacked and set fire to it. The city was formal ...

Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first trans- Atlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Positioning
Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position. Examples of vessel types that employ DP include ships and semi-submersible mobile offshore drilling units (MODU), oceanographic research vessels, cable layer ships and cruise ships. The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. This knowledge, combined with the sensor information, allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built By Daewoo Shipbuilding & Marine Engineering
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were co ...
