Ocean Ranger
''Ocean Ranger'' was a semi-submersible mobile offshore drilling unit that sank in Canadian waters on 15 February 1982. It was drilling an exploration well on the Grand Banks of Newfoundland, east of St. John's, Newfoundland, for Mobil Oil of Canada, Ltd. (MOCAN) with 84 crew members on board when it sank. There were no survivors. History and design ''Ocean Ranger'' was designed and owned by Ocean Drilling and Exploration Company, Inc. (ODECO) of New Orleans. The vessel was a self-propelled large semi-submersible design with a drilling facility and living quarters. It was capable of operation beneath of ocean water and could drill to a maximum depth of . It was described by ODECO as the world's largest semi-submersible oil rig to date. Constructed for ODECO in 1976 by Mitsubishi Heavy Industries in Hiroshima, Japan, ''Ocean Ranger'' was long, wide, and high. It had twelve anchors. The weight was 25,000 tons. It was floating on two long pontoons that rested below th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cook Inlet
Cook Inlet ( tfn, Tikahtnu; Sugpiaq: ''Cungaaciq'') stretches from the Gulf of Alaska to Anchorage in south-central Alaska. Cook Inlet branches into the Knik Arm and Turnagain Arm at its northern end, almost surrounding Anchorage. On its southern end, it merges with Shelikof Strait, Stevenson Entrance, Kennedy Entrance and Chugach Passage. The Cook Inlet watershed is the most populated watershed in Alaska. The watershed covers about of southern Alaska, east of the Aleutian Range, south and east of the Alaska Range, receiving water from its tributaries, the Knik River, the Little Susitna River, and the Susitna and Matanuska rivers. The watershed includes the drainage areas of Denali (formerly named Mount McKinley). Within the watershed there are several national parks and the active volcano Mount Redoubt, along with three other historically active volcanoes. Cook Inlet provides navigable access to the port of Anchorage at the northern end, and to the smaller Homer port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wellhead
A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment. The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment. While drilling the oil well, surface pressure control is provided by a blowout preventer (BOP). If the pressure is not contained during drilling operations by the column of drilling fluid, casings, wellhead, and BOP, a well blowout could occur. When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree, which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production. Wellheads are typically welded ont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confederation Building (Newfoundland And Labrador)
The Confederation Building serves as the home of the Newfoundland and Labrador House of Assembly. It is located on Confederation Hill overlooking Newfoundland and Labrador's capital city, St. John's, Newfoundland and Labrador, St. John's. The brick- and concrete-clad building has 11 stories and is tall. It was completed in 1960 at a cost of $9 million to replace the Colonial Building. A lantern is located at the top of the copper roof of the central tower and acts as a beacon when turned on at night.

Survival Suit
A survival suit, more accurately and currently referred to as an immersion suit, is a type of waterproof dry suit intended to protect the wearer from hypothermia if immersed in cold water or otherwise exposed after abandoning a vessel, especially in the open ocean. Immersion suits usually have integral footwear, and a hood, and either built-in gloves or watertight wrist seals. Suits manufactured by several manufacturers also include an inflatable pillow which is permanently attached high on the back, or an inflatable tube that is attached with zippers at two points on the chest, each side of the main zipper, and circles the back. When inflated, both of these devices provide enhanced stability to the wearer, which, if conscious, allows them to keep the head above water, and to keep wind and seas from striking the face. The inflation tube is routed from the inflatable pillow over the left shoulder of the user, and secured in a loop on the chest. Some immersion suits are provided ...

MV Mekhanik Tarasov
MV ''Mekhanik Tarasov'' was a Soviet Union-flagged cargo ship that was in service from 1976 until her sinking in 1982 in the North Atlantic Ocean. ''Mekhanik Tarasov'' was built by the Hollming shipyard of Rauma, Finland. She was laid down on 24 October 1975 and launched on 20 February 1976, and was delivered on 22 October 1976. She measured long, with a beam of , and had a service speed of from a single diesel-powered propeller. She had a gross tonnage of 4,262 GT and a deadweight tonnage of 5,306 DWT. In February 1982, ''Mekhanik Tarasov'' was sailing eastbound from Montreal to Leningrad with a mixed cargo of containers and about of newsprint when she encountered a severe storm. On the afternoon of 15 February, containers shifted in the heavy seas and punctured a ballast tank, causing the ship to list. During the afternoon, with the list reaching 30 degrees, the crew contacted the ship's shore agents requesting help before then declining assistance later in the evening f ...

Container Ship
A container ship (also called boxship or spelled containership) is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Container ship capacity is measured in twenty-foot equivalent units (TEU). Typical loads are a mix of 20-foot (1-TEU) and 40-foot (2-TEU) ISO-standard containers, with the latter predominant. Today, about 90% of non-bulk cargo worldwide is transported by container ships, and the largest modern container ships can carry up to 24,000 TEU (e.g., '' Ever Ace''). Container ships now rival crude oil tankers and bulk carriers as the largest commercial seaborne vessels. History There are two main types of dry cargo: bulk cargo and break bulk cargo. Bulk cargoes, like grain or coal, are transported unpackaged in the hull of the ship, generally in large volume. Break-bulk ...

Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a ...

Mayday (distress Signal)
Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure radio communications. It is used to signal a life-threatening emergency primarily by aviators and mariners, but in some countries local organizations such as firefighters, police forces, and transportation organizations also use the term. Convention requires the word be repeated three times in a row during the initial emergency declaration ("Mayday mayday mayday") to prevent it being mistaken for some similar-sounding phrase under noisy conditions, and to distinguish an ''actual'' mayday call from a message ''about'' a mayday call. History The "mayday" procedure word was conceived as a distress call in the early 1920s by Frederick Stanley Mockford, officer-in-charge of radio at Croydon Airport, England. He had been asked to think of a word that would indicate distress and would easily be understood by all pilots and ground staff in an emergency. Since much of the air traffic a ...

Porthole
A porthole, sometimes called bull's-eye window or bull's-eye, is a generally circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armored vehicles, aircraft, automobiles (the Ford Thunderbird a notable example) and even spacecraft. On a ship, the function of a porthole, when open, is to permit light and fresh air to enter the dark and often damp below- deck quarters of the vessel. It also affords below-deck occupants a limited view to the outside world. When closed, the porthole provides a strong water-tight, weather-tight and sometimes light-tight barrier. A porthole on a ship may also be called a sidescuttle or side scuttle (side hole), as officially termed in the International Convention for the Safety of Life at Sea. This term is used in the U.S. Code of Federal Regulations. It is also used in related rules and regulations for the construction of ships. The use of the ...
