Engineering Department
An engine department or engineering department is an organizational unit aboard a ship that is responsible for the operation, maintenance, and repair of the propulsion systems and the support systems for crew, passengers, and cargo. These include the ship engine, fuel oil, lubrication, water distillation, separation process, lighting, air conditioning, and refrigeration. The engine department emerged with the arrival of marine engines for propulsion, largely during the later half of the 19th century. Due to advances in marine technology during the 20th century, the engine department aboard merchant ships is considered equally important as the deck department, since trained engine officers are required to handle the machinery on a ship. The engine department takes care of the engine room aboard a ship. Rotations various depending on the vessel or company. Whoever is on a rotation has to stand watch to look over the engine room and its components. There are different crew mem ...

Argonaute Engine Control Room
The Argonaute protein family, first discovered for its evolutionarily conserved stem cell function, plays a central role in RNA silencing processes as essential components of the RNA-induced silencing complex (RISC). RISC is responsible for the gene silencing phenomenon known as RNA interference (RNAi). Argonaute proteins bind different classes of small non-coding RNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs) and Piwi-interacting RNAs (piRNAs). Small RNAs guide Argonaute proteins to their specific targets through sequence complementarity (base pairing), which then leads to mRNA cleavage, translation inhibition, and/or the initiation of mRNA decay. The name of this protein family is derived from a mutant phenotype resulting from mutation of AGO1 in '' Arabidopsis thaliana'', which was likened by Bohmert et al. to the appearance of the pelagic octopus '' Argonauta argo''. RNA interference RNA interference (RNAi) is a biological process in which the RNA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oiler (occupation)
An oiler (also known as a "greaser") is a worker whose main job is to oil machinery. In previous eras there were oiler positions in various industries, including maritime work ( naval and commercial), railroading, steelmaking, and mining. Today most such positions have been eliminated through technological change; lubrication tends to require less human intervention, so that workers seldom have oiling as a principal duty. In the days of ubiquitous plain bearings, oiling was often a job description in and of itself. Today, shipping is the economic segment that most thoroughly retains the notion of the oiler as a separate position. On a merchant ship, an oiler is an unlicensed rate of the engineering department. The position is of the junior rate in the engine room of a ship. The oiler is senior only to a wiper. Once a sufficient amount of sea time is acquired, the Oiler can apply to take a series of courses/examinations to become certified as an engineer. As a member of the en ...

Fourth Engineer
A fourth engineer or third assistant engineer is a rank of engine officer who is part of the engine department on a merchant vessel. Summary A third assistant engineer’s license is earned through the U.S.C.G or other regulatory body (such as the MCA in the UK) that allows the recipient to work on board any vessel up to the rank of a fourth engineer or below. It is earned by those who have completed the necessary STCW requirements to obtain it. Third assistant engineers work on board ships and do most of the general labor among the officers, as well as leading the oilers and other engine room crew. Depending on the style of ship, company, and other factors, they are called "the third" or "the fourth," usually stand a watch and sometimes assist the third mate in maintaining proper operation of the lifeboats. This credential, along with complementary endorsements and recognitions such as for tankers and cargo ships, is earned by cadets who complete the marine engineering tech ...

Third Engineer
A third engineer or second assistant engineer is a rank of engine officer who is part of the engine department on a ship. The third engineer is usually in charge of boilers, auxiliary engines, condensate and feed systems, record keeping of chemicals onboard, lube oil tests, and is the third most senior engine officer on board. The exact duties of this position will often depend upon the type of ship and arrangement of the engine department. On ships with steam propulsion plants the Second or Third is in charge of the boilers, combustion control, soot blowers, condensate and feed equipment, feed pumps, fuel, and condensers. On diesel and gas turbine propulsion plants the Third is in charge of auxiliary boilers, auxiliary engines. Notable Second assistant engineers * Raymond McKay * Paul Hall (labor leader) Paul Hall (1914 – June 22, 1980) was an American labor leader from Inglenook in Jefferson County, Alabama.

Second Engineer
A second engineer or first assistant engineer is a licensed member of the engineering department on a merchant vessel. This title is used for the person on a ship responsible for supervising the daily maintenance and operation of the engine department. They report directly to the chief engineer. On a merchant vessel, depending on term usage, "the First" or "the Second" is the marine engineer second in command of the engine department after the ship's chief engineer. Due to the supervisory role this engineer plays, in addition to being responsible for the refrigeration systems, main engines (steam/gas turbine, diesel), and any other equipment not assigned to the third engineer or fourth engineer(s), he is typically the busiest engineer aboard the ship. If the engine room requires 24/7 attendance and other junior engineers can cover the three watch rotations, the first is usually a "day worker" from 0800-1700, with overtime hours varying according to ship/company. The second engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chief Engineer
A chief engineer, commonly referred to as "ChEng" or "Chief", is the most senior engine officer of an engine department on a ship, typically a merchant ship, and holds overall leadership and the responsibility of that department..Chief engineer's rank is equivalent to the rank of a ship's captain. As a person who holds one of the most senior roles on the ship, they must have excellent communication and leadership skills. They will be expected to regularly work alongside other crew members and external consultants, and most importantly, provide guidance to their team. To be a chief engineer, an engineer must attain a chief engineer's license appropriate to the tonnage, power rating, and type of ship that they are employed on. A chief engineer is ultimately responsible for all operations and maintenance that has to do with any and all engineering equipment throughout the entire ship, and supervises all other engineering officer and engine ratings within the department.

Automation
Automation describes a wide range of technologies that reduce human intervention in processes, namely by predetermining decision criteria, subprocess relationships, and related actions, as well as embodying those predeterminations in machines. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Complicated systems, such as modern factories, airplanes, and ships typically use combinations of all of these techniques. The benefit of automation includes labor savings, reducing waste, savings in electricity costs, savings in material costs, and improvements to quality, accuracy, and precision. Automation includes the use of various equipment and control systems such as machinery, processes in factories, boilers, and heat-treating ovens, switching on telephone networks, steering, and stabilization of ships, aircraft, and other applications and vehicles with reduced hu ...

Coal Trimmer
A coal trimmer or trimmer is a position within the Engine department (ship), engineering department of a coal-fired ship which involves all coal handling duties. Their main task is to ensure that coal is evenly distributed within a vessel to ensure it remains trim in the water. Their efforts to control the fore-and-aft angle at which a ship floats is the reason they’re called “trimmers”. Without proper management of the coal bunkers, ships could easily List (watercraft), list due to uneven distribution of the coal. The role of trimmers starts with the bunkering of coal, distributing it evenly within the bunkers, and then providing a consistent delivery of coal to the Fireman (steam engine), stoker or fireman working the vessel’s boilers. Coal trimming was also a role based at the docks and would involve levelling out the coal in a ships hold to ensure that the ship was safe to travel. Coal was transported to the docks via train wagons and the coal was tipped into the sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeoli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireman (steam Engine)
A fireman, stoker or watertender is a person whose occupation it is to tend the fire for the running of a boiler, heating a building, or powering a steam engine. Much of the job is hard physical labor, such as shoveling fuel, typically coal, into the boiler's firebox. On steam locomotives the title ''fireman'' is usually used, while on steamships and stationary steam engines, such as those driving saw mills, the title is usually ''stoker'' (although the British Merchant Navy did use ''fireman''). The German word ''Heizer'' is equivalent and in Dutch the word ''stoker'' is mostly used too. The United States Navy referred to them as ''watertenders''. Nautical Royal Navy The Royal Navy used the rank structure ordinary stoker, stoker, leading stoker, stoker petty officer and chief stoker. The non-substantive (trade) badge for stokers was a ship's propeller. Stoker remains the colloquial term used to refer to a marine engineering rating, despite the decommissioning of the ...
