SS Emidio
''Hammac'' was a steam tank ship built in 1920–1921 by Bethlehem Shipbuilding Corporation of Alameda for the United States Shipping Board as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. Early in 1923 the vessel together with two other tankers was sold to General Petroleum Corporation and renamed ''Emidio''. The tanker spent the vast majority of her career carrying oil along the West Coast of the United States as well as between West and East coast. In December 1941 she was shelled and damaged by the and eventually wrecked with a loss of five crewmen. Design and construction After the United States entry into World War I, a large shipbuilding program was undertaken to restore and enhance shipping capabilities both of the United States and their Allies. As part of this program, EFC placed orders with nation's shipyards for a large number of vessels of standard designs. Design 1047 tank ship was a standa ...

United States Shipping Board
The United States Shipping Board (USSB) was established as an emergency agency by the 1916 Shipping Act (39 Stat. 729), on September 7, 1916. The United States Shipping Board's task was to increase the number of US ships supporting the World War I efforts. United States Shipping Board program ended on March 2, 1934. Initiation The United States' maritime position had been eroding for decades with some Congressional concern, some remedies actually worsening the situation, with European shipping companies dominating overseas trade and just over 10% of the value of trade carried in U.S. owned ships. The 1916 act was the result of Congressional efforts to create a board to address the problem dating from 1914. At this time the legislation was not a part of any war effort with specific intent as stated in the act: :"An Act to establish a United States Shipping Board for the purpose of encouraging, developing, and creating a naval auxiliary and naval reserve and a Merchant Marine to ...

The San Francisco Examiner
The ''San Francisco Examiner'' is a newspaper distributed in and around San Francisco, California, and published since 1863. Once self-dubbed the "Monarch of the Dailies" by then-owner William Randolph Hearst, and flagship of the Hearst Corporation chain, the ''Examiner'' converted to free distribution early in the 21st century and is owned by Clint Reilly Communications, which bought the newspaper at the end of 2020 along with the ''SF Weekly''. History Founding The ''Examiner'' was founded in 1863 as the ''Democratic Press'', a pro- Confederacy, pro-slavery, pro-Democratic Party paper opposed to Abraham Lincoln, but after his assassination in 1865, the paper's offices were destroyed by a mob, and starting on June 12, 1865, it was called ''The Daily Examiner''. Hearst acquisition In 1880, mining engineer and entrepreneur George Hearst bought the ''Examiner''. Seven years later, after being elected to the U.S. Senate, he gave it to his son, William Randolph Hearst, who was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thames Haven
Shell Haven was a port on the north bank of the Thames Estuary at the eastern end of Thurrock, Essex, England and then an oil refinery. The refinery closed in 1999 and the site was purchased by DP World who received planning consent in May 2007 for the new London Gateway deep water container port at the site. The neighbouring Coryton Refinery remained in operation until 2012. History Shell Haven appears on the 1596 edition of Saxton's Map 'Essexiae Comitat' Nova vera ac absaluta descriptio' It was possibly mentioned earlier. Shell Haven was mentioned in Samuel Pepys' Diary on 10 June 1667. The site, historically also referred to as Shellhaven was originally an inlet on the north bank of the Thames, about a mile to the west of Canvey Island. This was the mouth of Shell Haven Creek, which runs east and south of the village of Fobbing, and originally separated Corringham Marsh from Fobbing Marsh. To the east was Shell Haven House.

Union Oil
Union Oil Company of California, and its holding company Unocal Corporation, together known as Unocal was a major petroleum explorer and marketer in the late 19th century, through the 20th century, and into the early 21st century. It was headquartered in El Segundo, California, El Segundo, California, United States. Unocal was involved in domestic and global energy projects. Unocal was one of the key players in the CentGas consortium, which attempted to build the Trans-Afghanistan Pipeline to run from the Caspian area, through Afghanistan, to the Indian Ocean, at a time after the Afghan Civil War (1996–2001), Taliban siege of Kabul in 1996. On August 10, 2005, Unocal merged its entire Upstream (petroleum industry), upstream petroleum business with Chevron Corporation, Chevron and became a wholly-owned subsidiary. Unocal then ceased operations as an independent company, but continues to conduct many operations as Union Oil Company of California, a Chevron company. History T ...

The Los Angeles Times
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Benicia, California
Benicia ( , ) is a waterside city in Solano County, California, located in the North Bay region of the San Francisco Bay Area. It served as the capital of California for nearly thirteen months from 1853 to 1854. The population was 26,997 at the 2010 United States Census. The city is located along the north bank of the Carquinez Strait. Benicia is just east of Vallejo and across the strait from Martinez. Steve Young, elected in November 2020, is the mayor. History The City of Benicia was founded on May 19, 1847, by Dr. Robert Semple, Thomas O. Larkin, and Comandante General Mariano Guadalupe Vallejo, on land sold to them by General Vallejo in December 1846. It was named for the General's wife, Francisca Benicia Carillo de Vallejo, a member of the Carrillo family of California, a prominent Californio dynasty. The General intended that the city be named "Francisca" after his wife, but this name was dropped when the former city of "Yerba Buena" changed its name to "San Fran ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotch Boiler
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smokebox, outside the boiler shell. The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water. As such, it is a descendant of the earlier Lancashire boiler, and like the Lancashire it uses multiple separate furnaces to give greater heating area for a given furnace capacity. It differs from the Lancashire in two respects: many small-diameter tubes (typically diameter each) are used to increase the ratio of heating area to cross-section. Secondly, the overa ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

Triple Expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...
