Deck Department
The deck department is an organisational team on board navy, naval and merchant ship, 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 (nautical), bridge. However, they are usually also responsible for supervising and monitoring any maritime cargo on board, as well as ensuring maintenance of the deck (ship), deck and upper hull (watercraft), hull structure, monitoring the ship stability, stability of the ship, including loading and discharging ballast water discharge and the environment, ballast water, carrying out mooring (watercraft), mooring operations, and finally anchor, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underway Replenishment
Underway replenishment (UNREP) (United States Navy, U.S. Navy) or replenishment at sea (RAS) (North Atlantic Treaty Organization/Commonwealth of Nations) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century, it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely. History Concept Prior to underway replenishment, coaling stations were the only way to refuel ships far from home. The Royal Navy had an unparalleled global logistics network of coaling stations and the world's largest collier (ship), collier fleet. This capability allowed the Navy to power projection, project naval power around the world and far from home ports. This had two disadvantages: the infrastructure was vulnerable to disruption or attack, and its use introduced a predictable pattern to naval ...

Container Lashing With Rods
A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping. Things kept inside of a container are protected on several sides by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are often partly or completely rigid. A container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials. History Humans have used containers for at least 100,000 years, and possibly for millions of years.Clive Gamble, ''Origins and Revolutions: Human Identity in Earliest Prehistory'' (2007), p. 204. The first containers were probably invented for storing food, allowing early humans to preserve more of their food for a longer time, to carry it more easily, and also to protect it from other animals. The development of food storage con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Captain
A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade licensed mariner who holds ultimate command and responsibility of a merchant vessel. The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board. Duties and functions The captain ensures that the ship complies with local and international laws and complies also with company and flag state policies. The captain is ultimately responsible, under the law, for aspects of operation such as the safe navigation of the ship, its cleanliness and seaworthiness, safe handling of all cargo, management of all personnel, inventory of ship's cash and stores, and maintaining the ship's certificates and documentation. One of a shipmaster's particularly important duties is to ensure compliance with the vessel's security plan, as required by the ...

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 ...

List Of United States Navy Ratings
United States Navy ratings are general enlisted occupations used by the U.S. Navy since the 18th century, which denote the specific skills and abilities of the sailor. Each naval rating has its own specialty badge, which is worn on the left sleeve of dress uniforms of enlisted personnel. U.S. naval ratings are the equivalent of military occupational specialty codes (MOS codes) used by the United States Army and the United States Marine Corps, the ratings system used by the United States Coast Guard, and Air Force Specialty Codes (AFSC) used by the United States Air Force and United States Space Force. Ratings should not be confused with ''rates'', which are used to identify personnel of specific a rating and pay grade. For example, if a sailor has the pay-grade of E-5 (petty officer second class) and the rating of boatswain's mate, then combining the two—boatswain's mate second class (BM2)—defines both pay grade and rating in formal address or epistolary salutation.

Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Tackle
A mooring is any permanent structure to which a seaborne vessel (such as a boat, ship, or amphibious aircraft) may be secured. Examples include quays, wharfs, Jetty, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An ''anchor mooring'' fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, ''mooring'' refers to the act of attaching a vessel to a mooring. The term likely stems from the Dutch language, Dutch verb ''meren'' (to ''moor''), used in English since the end of the 15th century. Permanent anchor mooring These moorings are used instead of temporary anchors because they have considerably more holding power. They cause lesser damage to the marine environment, and are convenient. Where there is a row of moorings they are termed a tier. They are also occasionally used to hold floating docks in place. There are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailors
A sailor, seaman, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, and may work in any one of a number of different fields that are related to the operation and maintenance of a ship. While the term ''sailor'' has its etymological roots from sailing, that is a time when sailing ships were the main mode of transport at sea, it now refers to the personnel of all watercraft regardless of the type of vessel, boat or ship. It encompasses people who operate ships professionally, be it for a military (navy) or civilian (merchant navy) or for Sailing (sport), sports or recreation. In a navy, there may be further distinctions: ''sailor'' may refer to any member of the navy even if they are based on land, while Seaman (rank), ''seaman'' may refer to a specific enlisted rank. Additionally, fisherman are seen as a distinct type of sailor, that is those engaged in fishing. Sailors have existed from the earliest periods in history as people as people used b ...

Watch Officer
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 (nautical), 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 v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chief Mate
A chief mate (C/M) or chief officer, usually also synonymous with the first mate or first officer, is a licensed mariner and head of the deck department of a merchant ship. The chief mate is customarily a watchstander and is in charge of the ship's cargo and deck crew. The actual title used will vary by ship's employment, by type of ship, by nationality, and by trade: for instance, ''chief mate'' is not usually used in the Commonwealth of Nations, Commonwealth, although ''chief officer'' and ''first mate'' are; on passenger ships, the first officer may be a separate position from that of the chief officer that is junior to the latter. The chief mate answers to the Sea captain, captain for the safety and security of the ship. Responsibilities include the crew's welfare and training in areas such as safety, firefighting, search and rescue. The mate on a fishing vessel may be called the second hand. Senior onboard operations manager The Chief Mate, who is the Second-in-command, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanker (ship)
A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in Bulk liquids, bulk. Major types of tanker ship include the oil tanker (or petroleum tanker), the chemical tanker, Cargo ship, cargo ships, and a gas carrier. Tankers also carry commodities such as vegetable oils, molasses and wine. In the United States Navy and Military Sealift Command, a tanker used to refuel other ships is called an oiler (ship), oiler (or replenishment oiler if it can also supply dry stores) but many other navies use the terms tanker and replenishment tanker. Tankers were first developed in the late 19th century as iron and steel hulls and pumping systems were developed. As of 2005, there were just over 4,000 tankers and supertankers or greater operating worldwide. Description Tankers can range in size of capacity from several hundred tonnage, tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, f ...

Polar Regions
The polar regions, also called the frigid geographical zone, zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North Pole, North and South Poles), lying within the polar circles. These high latitudes are dominated by floating Arctic ice pack, sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south. Definitions The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60th parallel north, 60° north latitude, or the region from the North Pole south to the Tree line, timberline. The Antarctic is usually defined simply as south of 60th parallel south, 60° south latitude, or the continent of Antarctica. The 1959 Antarctic Treaty System, Antarctic Treaty uses the former definition. The two polar regions are distinguis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
