Engine 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 vary depending on the vessel or company. Whoever is on a rotation has to stand watch to look over the engine and its components. There are different crew members for wat ...

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 RNA molec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oiler (occupation)
An oiler (also known as a "greaser") is a worker whose main job is Lubrication, to oil machinery. In previous eras there were oiler positions in various industries, including maritime work (navy, naval and Ship transport, commercial), Rail transport, 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 vessel, 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 (occupation), wiper. Once a sufficient amount of sea time is acquired, the Oiler can apply to take a seri ...

Motorman (ship)
A motorman, also known as a qualified member of the engineering department (QMED), is the seniormost rate in the engine room of a ship. The motorman performs a variety of tasks connected with the maintenance and repair of engine room, fireroom, machine shop, ice-machine room, and steering-engine room equipment. The motorman inspects equipment such as pumps, turbines, distilling plants, and condensers, and prepares record of condition. The motorman lubricates and maintains machinery and equipment such as generators, steering systems, lifeboats, and sewage disposal systems, and also cleans and restores tools and equipment. United States In the United States Merchant Marine, in order to be occupied as a QMED a person has to have a Merchant Mariner Credential issued by the United States Coast Guard with a QMED certification. Because of international conventions and agreements, all QMEDs who sail internationally are similarly documented by their respective countries. Applicants for QM ...

Cadet
A cadet is a student or trainee within various organisations, primarily in military contexts where individuals undergo training to become commissioned officers. However, several civilian organisations, including civil aviation groups, maritime organisations, and police services, also designate their trainees as cadets. Armed forces In several military services, cadets, flight cadets, officer cadets, and gentleman/lady cadets may refer to recruits and students that are undergoing military training to become commissioned officers. The specific rank structure and responsibilities of cadets can vary among different military organisations. Australia In Australia, a cadet is an officer in training. The official rank is Officer Cadet (OCDT for members of the Australian Regular Army and OFFCDT for members of the Royal Australian Air Force), but OCDTs in the Royal Military College–Duntroon are referred to as ''staff cadet'' (Scdt) for historical reasons.

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.

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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chief Engineer
A chief engineer, commonly referred to as "Chief" or "ChEng", is the most senior licensed mariner (engine officer) of an engine department on a ship, typically a merchant ship, and holds overall leadership and the responsibility of that department. In rank, a chief engineer 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 the engineer is 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 ...

Automation
Automation describes a wide range of technologies that reduce human intervention in processes, mainly 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 system, mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Complicated systems, such as modern Factory, 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, Stabilizer (ship), stabilization of ships, aircraft and other applic ...

Coal Trimmer
A coal trimmer or trimmer is a position within the engineering department of a coal-fired steamship that involves all coal handling duties. Their main task is to ensure that coal is evenly distributed within a ship to ensure it remains trim in the water. Their efforts to control the fore-and-aft angle at which a ship floats are why they are called “trimmers”. Without proper management of the coal bunkers, ships could easily 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 stoker or fireman working the vessel's boilers. Coal trimming was also a role based at the docks that involved levelling out the coal in a ship's hold to ensure that the ship was safe to travel. Coal was transported to the docks on railway wagons, and the coal was tipped into the ship. As the coal was loaded into a hold of the ship it would form a conica ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), 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 (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they 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 Boiler (power generation), boilers etc.), such as railway steam locomot ...

Fireman (steam Engine)
A fireman, stoker or boilerman is a person who tends 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 Seaman (rating), stoker 2nd class, Able Seaman (rank), stoker 1st Class, Leading Seaman, leading stoker, Petty Officer, stoker petty officer and Chief Petty Officer, chief stoker. The non-substantive (trade) badge for stokers was a ship's propeller. "Stoker" remains the colloquial ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
