USNS Shenandoah
The fifth USNS ''Potomac'' (T-AO-181) was a United States Navy oiler in non-commissioned service with the Military Sea Transportation Service, later Military Sealift Command, from 1976 to 1983. ''Potomac'', sixth U.S. Navy ship to bear the name, was laid down as SS ''Shenandoah'' at Sun Shipbuilding and Drydock Company at Chester, Pennsylvania, on 1 March 1964 and launched on 10 October 1964. She was built using the 200-foot (61 m) salvaged stern section of the oiler USNS ''Potomac'' (T-AO-150)—a ship which had been destroyed by a fire on 26 September 1961—to which a new forward section was added. She was the first ship equipped with an offshore petroleum discharge system (OPDS), allowing her to supply petroleum products to forces ashore by pumping it directly over the shore instead of having to deliver it in a port. The U.S. Navy acquired ''Shenandoah'' on 10 October 1964, and delivered her to Keystone Shipping Company on 11 December 1965. Keystone Shipping then chart ...

Steam
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into work (physics), mechanical work by steam engines such as reciprocating engine, reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, vapour pressure, it can create a steam exp ...

Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhoushan.

Stern
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night. Sterns on European and American wooden sailing ships began with two principal forms: the ''square'' or ''transom'' stern and the ''elliptical'', ''fantail'', or ''merchant'' stern, and were developed in that order. The hull sections of a sailing ship located before the stern were composed of a series of U-shaped rib-like frames set in a sloped or "cant" arrangement, with the last frame before the stern being called the ''fashion timber(s)'' or ''fashion piece(s)'', so called for "fashioning" the after part of the ship. This frame i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Sea Transportation Service
The Military Sealift Command (MSC) is an organization that controls the replenishment and military transport ships of the United States Navy. Military Sealift Command has the responsibility for providing sealift and ocean transportation for all US military services as well as for other government agencies. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970. Military Sealift Command ships are made up of a core fleet of ships owned by the United States Navy and others under long-term-charter augmented by short-term or voyage-chartered ships. * During a time charter MSC takes control of a merchant ship and operates it for the chartered amount of time. During this time the ship is crewed by civilian mariners and MSC pays for all expenses. Time chartered ships are not subject to inspections from foreign ...

Replenishment Oiler
A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers. The US Navy hull classification symbol, United States Navy's hull classification symbol for this type of ship was 'AOR' (Auxiliary Oil Replenishment). Replenishment oilers are slower and carry fewer dry stores than the US Navy's modern fast combat support ships, which carry the classification 'AOE'. In 2020 the US Navy began to develop a new type of ship, the 'AOL' or List of United States Navy oilers#Light Replenishment Oilers (T-AOL), light replenishment oiler; construction of the first is planned for 2026. History The development of the "oiler" paralleled the change from coal- to oil-fired boilers in warships. Prior to the adoption of oil fired machinery, navies could extend the range of their ships either by maintaining coaling stations ...

USNS Potomac (T-AO-150)
USNS ''Potomac'' (T-AO-150) was a United States Navy ''Maumee''-class oiler in non-commissioned service with the Military Sea Transportation Service, later Military Sealift Command, from 1957 to 1961. ''Potomac'', fifth U.S. Navy ship to bear the name, was laid down at Sun Shipbuilding and Drydock Company at Chester, Pennsylvania, on 9 June 1955 and launched on 8 October 1956, sponsored by Mrs. T. H. Robbins, Jr. She entered non-commissioned U.S. Navy service under the control of the Military Sea Transport Service (MSTS) with a primarily civilian crew on 30 January 1957. ''Potomac'' carried fuel oil and aviation fuel to the United States armed forces overseas until 26 September 1961, when she was wracked by fire and a series of explosions while alongside the Aviation Fuels Terminal Pier at Morehead City, North Carolina.

Civilian
A civilian is a person who is not a member of an armed force. It is war crime, illegal under the law of armed conflict to target civilians with military attacks, along with numerous other considerations for civilians during times of war. If a civilian engages in hostilities, they are an unlawful combatant and temporarily lose their protection from attack. It is slightly different from a non-combatant, because some non-combatants are not civilians (for example, people who are not in a military but support war effort or military operations, military chaplains, or military personnel who are serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary international law, customary laws of war and Treaty, international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is an internal one (a civil war) or an internationa ...

Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers ( IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization ( ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately).
