A double-hulled tanker refers to an oil tanker which has a double hull. They reduce the likelihood of leaks occurring compared to single-hulled tankers, and their ability to prevent or reduce oil spills led to double hulls being standardized for oil tankers and other types of ships including by the International Convention for the Prevention of Pollution from Ships or MARPOL Convention. After the Exxon Valdez oil spill disaster in Alaska in 1989, the US Government required all new oil tankers built for use between US ports to be equipped with a full double hull.
The Exxon Valdez oil spill occurred in Prince William Sound, Alaska, on March 24, 1989, when Exxon Valdez, an oil tanker owned by Exxon Shipping Company that was bound for Long Beach, California struck Prince William Sound's Bligh Reef, 1.5 mi (2.4 km) west of Tatitlek, Alaska at 12:04 a.m. and spilled 10.8 million US gallons (257,000 bbl) of crude oil over the next few days.
The Sea Shepherd Conservation Society (SSCS) is a non-profit, marine conservation organization based in Friday Harbor on San Juan Island, Washington, in the United States.
Rum-running or bootlegging is the illegal business of transporting (smuggling) alcoholic beverages where such transportation is forbidden by law. Smuggling usually takes place to circumvent taxation or prohibition laws within a particular jurisdiction. The term rum-running is more commonly applied to smuggling over water; bootlegging is applied to smuggling over land.
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks.
MS Caribbean Princess is a modified Grand-class cruise ship owned and operated by Princess Cruises, with a capacity of over 3,600 passengers, the largest carrying capacity in the Princess fleet until June 2013 when the new Royal Princess, another Princess ship superseded its record. She has 900 balcony staterooms and a deck of mini-suites.
Environmental dumping is the practice of transfrontier shipment of waste from one country to another. The goal is to take the waste to a country that has less strict environmental laws, or environmental laws that are not strictly enforced. The economic benefit of this practice is cheap disposal or recycling of waste without the economic regulations of the original country.
The 2006 Ivory Coast toxic waste dump was a health crisis in Ivory Coast in which a ship registered in Panama, the Probo Koala, chartered by the Singaporean-based oil and commodity shipping company Trafigura Beheer BV, offloaded toxic waste to an Ivorian waste handling company which disposed of it at the port of Abidjan. The local contractor, a company called Tommy, dumped the waste at 12 sites in and around the city in August 2006. The dumping, which took place against a backdrop of instability in Abidjan as a result of Côte d'Ivoire's first civil war, allegedly led to the death of 7 and 20 hospitalized and the other 26000 people were being treated for symptoms of poisoning.
The Nisshin Maru (日新丸) is the primary vessel of the Japanese whaling fleet and is the world's only whaler factory ship. It has a tonnage of 8,145 GT and is the largest member and flagship of the five-ship whaling fleet, headed by leader Shigetoshi Nishiwaki. The ship is based in Japan in Shimonoseki harbor and is owned by Tokyo-based Kyodo Senpaku, which is a subsidiary of the Institute of Cetacean Research.
MV New Flame was a Panamanian bulk-carrier cargo ship. It collided with an oil tanker off Europa Point, the southernmost tip of Gibraltar on 12 August 2007, and ended up partially submerged in the Strait of Gibraltar. The vessel broke into two in December 2007 amid numerous unsuccessful recovery efforts. The cargo was salvaged and the stern section removed for scrap. Following the crew's rescue, the captain was arrested for having departed without authorisation. Charges of endangering shipping were later dropped.
The squat effect is the hydrodynamic phenomenon by which a vessel moving quickly through shallow water creates an area of lowered pressure that causes the ship to be closer to the seabed than would otherwise be expected. This phenomenon is caused when water that should normally flow under the hull encounters resistance due to the close proximity of the hull to the seabed. Leonardo's law causes the water to move faster in water level ; according to Bernoulli's principle, the increasing velocity causes low pressure, such that the ship is pulled down. Squat effect from a combination of vertical sinkage and a change of trim may cause the vessel to dip towards the stern or towards the bow.
The Motor Vessel Tecam Sea is a bulk carrier built in 1984. The ship was built by Hitachi Zosen shipyard in Innoshima, Japan, and purchased by Sea Quality, a shipping company based in Athens, Greece. The ship was involved in a collision with the M/V Federal Fuji in the port of Sorel, Quebec on 27 April 2000. The squat effect phenomenon is believed to be a factor in the collision.
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets.
CCGS John G. Diefenbaker is the name for a Canadian Coast Guard icebreaker that had been expected to join the fleet by 2017 but has been significantly delayed. Her namesake, John G. Diefenbaker, was Canada's 13th prime minister. It was Diefenbaker's government that founded the Canadian Coast Guard in 1962.
Cruise ships carrying several thousand passengers and crew have been compared to “floating cities,” and the volume of wastes that they produce is comparably large, consisting of sewage; wastewater from sinks, showers, and galleys (graywater); hazardous wastes; solid waste; oily bilge water; ballast water; and air pollution. The waste streams generated by cruise ships are governed by a number of international protocols and U.S. domestic laws, regulations, and standards, but there is no single law or rule. Some cruise ship waste streams appear to be well regulated, such as solid wastes and bilge water. But there is overlap of some areas, and there are gaps in others.
Piracy off the coast of Somalia occurs in the Gulf of Aden, Guardafui Channel and Somali Sea, in Somali territorial waters and other surrounding areas. It was initially a threat to international fishing vessels, expanding to international shipping since the Consolidation of states within Somalia (1998–2006) of the Somali Civil War, around 2000.
The environmental effects of shipping include air pollution, water pollution, acoustic, and oil pollution. Ships are responsible for more than 18 percent of some air pollutants.
AISSat-1 is a satellite used to receive Automatic Identification System (AIS) signals. Launched on 12 June 2010 from Satish Dhawan Space Center as a secondary payload, AISSat-1 is in a sun-synchronous low-Earth orbit. Initially a development project, the satellite has since passed into ordinary operations. Via downlinks at Svalbard Satellite Station and at Vardø Vessel Traffic Service Centre it tracks vessels in the Norwegian Sea and Barents Sea for the Norwegian Coastal Administration, the Norwegian Coast Guard, the Norwegian Directorate of Fisheries and other public agencies.
The Jura was a wooden, flush deck, paddle steamer, originally built for service on Lake Neuchâtel, but which was sold after seven years to work on Lake Constance, and sank in 1864 after a collision with the Stadt Zürich.
