Ship Disposal
A number of different methods exist for disposing of a ship after it has reached the end of its effective or economic service life with an organisation. Options Although many options are technically possible, some, such as deep water sinking, are not used for non-military vessels, or have come under increased scrutiny. Options currently available include: * Hulking * Ship breaking (involving recycling) * Use as an artificial reef * Donation * Sale for re-use * Floating (or drydock) storage * Deep water sinking Description of options * Hulking was a traditional method of converting a hull to another purpose after its usefulness as a ship had ended. The ship is stripped of its motive equipment (sails and rigging or motors) and is used for a variety of purposes. This practice is still in use to a limited extent. * Ship breaking is the most common and most environmentally accepted method of ship disposal. According to various organisations, only facilities approved by the Basel Act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hulk (ship)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) w ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Artificial Reef
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing. Many reefs are built using objects that were built for other purposes, such as by sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Other artificial reefs are purpose-built (e.g. the reef balls) from PVC or concrete. Shipwrecks may become artificial reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach; the accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. History The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basel Action Network
The Basel Action Network (BAN), a charitable non-governmental organization, works to combat the export of toxic waste from technology and other products from industrialized societies to developing countries. BAN is based in Seattle, Washington, United States, with a partner office in the Philippines. BAN is named after the Basel Convention, a 1989 United Nations treaty designed to control and prevent the dumping of toxic wastes, particularly on developing countries. BAN serves as an unofficial watchdog and promoter of the Basel Convention and its decisions. Campaigns BAN currently runs four campaigns focusing on decreasing the amount of toxins entering the environment and protecting underdeveloped countries from serving as a toxic dump of the developed countries of the world."About the Basel Action Network," BAN.org.

Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sinking Ships For Wreck Diving Sites
Sinking ships for wreck diving sites is the practice of scuttling old ships to produce artificial reefs suitable for wreck diving, to benefit from commercial revenues from recreational diving of the shipwreck, or to produce a diver training site. To avoid undesirable ecological impact, and to maximise utility, the vessel should be selected and prepared, and the site chosen, with due consideration to the local environment. Preparation To prepare a hulk for sinking as a wreck site, several things must be done to make it safe for the marine environment and divers. To protect the environment, the ship is purged of all oils, hydraulic fluids, and dangerous chemicals such as PCBs. Much of the superstructure may be removed to prevent the hazard of it eventually caving in from corrosion. Similarly, the interior of the ship is gutted of components that corrode quickly, and would be dangerous to divers if they came loose. The ship is thoroughly cleaned, often with the help of volunteers i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Houseboat
A houseboat is a boat that has been designed or modified to be used primarily as a home. Most houseboats are not motorized as they are usually moored or kept stationary at a fixed point, and often tethered to land to provide utilities. However, many are capable of operation under their own power. ''Float house'' is a Canadian and American term for a house on a float (raft); a rough house may be called a ''shanty boat''. In Western countries, houseboats tend to be either owned privately or rented out to holiday-goers, and on some canals in Europe, people dwell in houseboats all year round. Examples of this include, but are not limited to, Amsterdam, London, and Paris. Africa South Africa There are a few houseboat options in South Africa, including self-drive houseboats on the Knysna, Knysna Lagoon and fully catered luxury houseboats on Pongolapoort Dam, Lake Jozini. There has been a number of serious incidents with houseboat fires in the country. On 19 November 2016, four pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SINKEX
A target ship is a vessel — typically an obsolete or captured warship — used as a seaborne target for naval gunnery practice or for weapons testing. Targets may be used with the intention of testing effectiveness of specific types of ammunition; or the target ship may be used for an extended period of routine target practice with specialized non-explosive ammunition. The potential consequences of a drifting wreck require careful preparation of the target ship to prevent pollution, or a floating or submerged collision risk for maritime navigation. Rationale Sinking redundant warships is an effective way of testing new weapons and warships in as realistic a manner as possible. Preparation In order to meet environmental, health, and safety standards, ships now have to be thoroughly cleaned so that all dangerous material and potential contaminants (such as asbestos, refrigerants etc.) are removed. In the event of the vessel becoming an artificial reef, escape exits also have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norwegian Cruise Line (NCL), also known in short as Norwegian, is an American cruise line founded in 1966, incorporated in Bermuda and headquartered in Miami. It is the List of cruise lines, fourth-largest cruise line in the world by passengers, controlling about 8.6% of the total worldwide share of the cruise market by passengers . It is wholly owned by parent company Norwegian Cruise Line Holdings. History The cruise line was founded in 1966 by Norwegian Knut Kloster and Israeli Ted Arison, with the 8,666-ton, 140-m long Cruiseferry, cruise ship/car ferry, , which in 1966 operated as a car ferry between Southampton UK and Gibraltar, for that one short season only. The ''Sunward'' was first managed under the Arison Shipping Company, and marketed as Ensign Cruises. Arison soon left to form Carnival Cruise Lines, while Kloster acquired additional ships for Caribbean service, with the line renamed and marketed as Norwegian Caribbean Line.
