Watchstanding
Watchkeeping or watchstanding is the assignment of sailors to specific roles on a ship to operate it continuously. These assignments, also known at sea as ''watches'', are constantly active as they are considered essential to the safe operation of the vessel and also allow the ship to respond to emergencies and other situations quickly. These watches are divided into work periods to ensure that the roles are always occupied at all times, while those members of the crew who are assigned to work during a watch are known as ''watchkeepers''. On a typical seafaring vessel, be it naval or merchant, personnel "keep a watch" in various locations and duties across the ship, such as the bridge and engine room. Typical bridge watchkeepers include a lookout and a deck officer who is responsible for the safe navigation of the ship; whereas in the engine room, an engine officer ensures that running machinery continues to operate within tolerances. Types of watches A wide variety of types o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck Officer
The deck department is an organisational team on board naval and merchant ships. Seafarers in the deck department work a variety of jobs on a ship or vessel, but primarily they will carry out the navigation of a vessel from the bridge. However, they are usually also responsible for supervising and monitoring any maritime cargo on board, as well as ensuring maintenance of the deck and upper hull structure, monitoring the stability of the ship, including loading and discharging ballast water, carrying out mooring operations, and finally anchoring a ship. Among the merchant fleets of countries that have ratified the STCW Convention, the department and its manning requirements, including the responsibilities of each rank are regulated by that STCW Convention. The department is led by deck officers, who are licensed mariners, and they are commanded overall by the ship's captain. Merchant shipping The deck department is divided into deck officers and ratings. All ranks i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boatswain
A boatswain ( , ), bo's'n, bos'n, or bosun, also known as a deck boss, or a qualified member of the deck department, or the third hand on a fishing vessel, is the most senior Naval rating, rate of the deck department and is responsible for the components of a ship's Hull (watercraft), hull. The boatswain supervises the other members of the ship's deck department, and typically is not a watchstanding, watchstander, except on vessels with small crews. Additional duties vary depending upon ship, crew, and circumstances. History The word ''boatswain'' has been in the English language since approximately 1450. It is derived from late Old English language, Old English ''batswegen'', from ''bat'' (''boat'') concatenated with Old Norse language, Old Norse ''sveinn'' (''wikt:swain, swain''), meaning a young man, apprentice, a follower, Retinue, retainer or Servant (domestic), servant. Directly translated to modern Norwegian it would be ''båtsvenn'', while the actual crew title in Norwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Officer Of The Deck
An officer of the deck (OOD) underway is a watchstanding duty officer on a surface ship in the United States Navy, United States Coast Guard, and NOAA Commissioned Officer Corps who is tasked with certain duties and responsibilities for the ship. The officer of the deck is either subordinate to the command duty officer or, in the absence of one, reports directly to the ship's commanding officer and executive officer, in the latter case holding responsibility for the ship altogether. This article describes duties and responsibilities for an underway OOD for surface ships only. Overview In port, the OOD is stationed on the quarterdeck, which is the entry point to the ship. All personnel and visitors must cross the quarterdeck to enter the ship. It is a ceremonial space, representing the ship to visitors. In addition, the OOD has a qualified petty officer manning the gangplank, called the petty officer of the watch (POOW). The POOW is in the position of managing who comes and goes, ...

Engine Officer
An engine officer or simply engineer, is a licensed mariner qualified and responsible for operating and maintaining the propulsion plants and support systems for a watercraft and its crew, passengers and cargo. Engineering officers are usually educated and qualified as engineering technicians. Ship engineers are responsible for propulsion and other ship systems such as: electrical power generation plant; steam boilers; lighting; fuel oil; lubrication; water distillation and separation; air conditioning; refrigeration; sewage treatment and water systems on board the vessel. They require knowledge and hands-on experience with electric power, electronics, pneumatics, hydraulics, chemistry, steam generation, gas turbines and even nuclear technology on certain military and civilian vessels. Ranks and titles There are several types and ranks of engine officer that are employed in the engine department of a ship Watchstanding officers *Chief engineer:Chief engineer is the highes ...

Command Duty Officer
A command duty officer (CDO, on a naval ship) or officer of the watch (OOW, on a merchant ship) is the head duty officer (officer of the day) on a ship, entrusted by the commanding officer and executive officer (on a naval ship) or the shipmaster (on a merchant ship) with exercising in their absence command and control of the ship on their behalf for the duration of a watch. Navy In the US Navy, the Command Duty Officer carries out the duties of the commanding officer "in the absence of the commanding officer or the executive officer, or both." The CDO supervises other junior watchkeeping officers such as the officer of the deck. They are typically assigned for ships in port or land naval installations though they may also be found underway on larger warships. While many watchkeepers stand watch for a few hours continuously at a time, CDOs may be on duty for longer periods, such as a day or a week. Whilst the CDO may be outranked by more senior officers on board, the CDO is only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Of Nations

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Starboard
Port and starboard are Glossary of nautical terms (M-Z), nautical terms for watercraft and spacecraft, referring respectively to the left and right sides of the vessel, when aboard and facing the Bow (watercraft), bow (front). Vessels with bilateral Symmetry (geometry), symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side; it is usually only on the port side (hence the name). Side Port side and starboard side respectively refer to the left and right sides of the vessel, when aboard and facing the bow. The port and starboard sides of the vessel always refer to the same portion of the vessel's structure, and do not depend on the position of someone aboard the vessel. The port side is the side to the left of an observer aboard the vessel and , towards the direction the vessel is heading when underway in the forward direction. The starboard side is to the right of such an obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is ...

Dog Watch
A dog watch is a work shift, also known as a "watch", in a maritime watch system that is half the length of a standard watch period. This is typically formed by splitting a single four-hour watch period between 16:00 and 20:00 (4 pm and 8 pm) to form two two-hour dog watches, with the "first" dog watch from 16:00 to 18:00 (4 pm to 6 pm) and the "second" or "last" dog watch from 18:00 to 20:00 (6 pm to 8 pm). This watch exists because, in order for the crew to rotate through all the watches, it is necessary to have an odd number of watches in a ship's day. Splitting one of the watches in half allows the sailors to stand different watches instead of one team being forced to stand the mid-watch every night. The choice of time also allows both watches, if there are only two, to eat an evening meal at about the traditional time. Etymology The ''Oxford English Dictionary'' states that the word 'dogwatch' is a direct translation from either German or Dutch of a similar term. It or ...
