Maritime Pilot
A maritime pilot, marine pilot, harbor pilot, port pilot, ship pilot, or simply pilot, is a mariner who has specific knowledge of an often dangerous or congested waterway, such as harbors or river mouths. Maritime pilots know local details such as depth, currents, and hazards. They board and temporarily join the crew to safely guide the ship's passage, so they must also have expertise in handling ships of all types and sizes. Obtaining the title "maritime pilot" requires being licensed or authorised by a recognised pilotage authority. History The word ''pilot'' is believed to have come from the Middle French, ''pilot'', ''pillot'', from Italian, ''pilota'', from Late Latin, ''pillottus''; ultimately from Ancient Greek πηδόν (pēdón, "blade of an oar, oar"). The work functions of the pilot can be traced back to Ancient Greece and Ancient Rome, Rome, when locally experienced harbour captains, mainly local fishermen, were employed by incoming ships' captains to bring t ...

Pilot Boat
A pilot boat is a type of boat used to transport maritime pilots between land and the inbound or outbound ships that they are piloting. Pilot boats were once sailing boats that had to be fast because the first pilot to reach the incoming ship got the business. Today, pilot boats are scheduled by telephoning the ship agents/representatives prior to arrival. History Pilots and the work functions of the maritime pilot go back to Ancient Greece and Ancient Rome, Roman times, when incoming ships' captains employed locally experienced harbour captains, mainly local fishermen, to bring their vessels safely into port. Eventually, in light of the need to regulate the act of pilotage and ensure pilots had adequate insurance, the harbours themselves licensed pilots for each harbour. Although licensed by the harbour to operate within their jurisdiction, pilots were generally self-employed, meaning that they had to have quick transport to get them from the port to the incoming ships.

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Tank Ship
A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tanker ship include the oil tanker (or petroleum tanker), the chemical tanker, 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 (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 tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Container Ship
A container ship (also called boxship or spelled containership) is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Container ship capacity is measured in twenty-foot equivalent units (TEU). Typical loads are a mix of 20-foot (1-TEU) and 40-foot (2-TEU) ISO-standard containers, with the latter predominant. Today, about 90% of non-bulk cargo worldwide is transported by container ships, the largest of which, from 2023 onward, can carry over 24,000 TEU. History There are two main types of dry cargo: bulk cargo and break bulk cargo. Bulk cargoes, like grain or coal, are transported unpackaged in the hull of the ship, generally in large volume. Break-bulk cargoes, in contrast, are transported in packages, and are generally manufactured goods. Before the advent of containerization in the ...

Deck (ship)
A deck is a permanent covering over a Compartment (ship), compartment or a hull (watercraft), hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists Tension (physics), tension, Compression (physics), compression, and racking forces. The deck's scantling is usually the same as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Ladder
A pilot ladder is a highly specialized form of Ladder#Flexible ladders, rope ladder, typically used on board cargo ship, cargo vessels for the purposes of embarking and disembarking maritime pilot, pilots. The design and construction of the ladders is tightly specified by international regulation under the SOLAS Convention, SOLAS regime. Pilot ladders and other boarding arrangements must be carefully prepared for each operation, with the equipment inspected and verified as safe to use before each boarding takes place. Additional requirements relate to the use of man-ropes, platforms, accommodation ladders, combination ladders and securing methods. Construction The ladders are made by threading and fixing a series of hardwood, machining, machined steps, each not more than , onto two pairs of minimum diameter abacá, manila ropes, and binding each step to the ropes at intervals. At a maximum interval of eight steps, the standard step is replaced by a ''spreader'', which is an elon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

California Board Of Pilot Commissioners
Board of Pilot Commissioners for the Bays of San Francisco, San Pablo, and Suisun is the California state agency responsible for licensing and regulating pilots within one of the largest harbors in the world and the tributary Sacramento River delta. It licenses and regulates up to 60 pilots of the San Francisco Bar Pilots Association. They are called "bar pilots" because they maneuver ships across a large and dangerous sand bar just outside the Golden Gate at the mouth of San Francisco Bay. The Board of Commissioners was created in 1850 during the first session of the California State Legislature. Once an independent agency, the Board of Commissioners became a department of the California Business, Transportation and Housing Agency in 2009 and currently is part of the California State Transportation Agency. Surcharges paid by shippers on pilotage fees finance the work of the Commission, making it completely self-supporting. Jurisdiction The commission's jurisdiction inclu ...

Merchant Shipping Act 1894
The Merchant Shipping Act 1894 ( 57 & 58 Vict. c. 60) was an act of the Parliament of the United Kingdom that consolidated enactments relating to merchant shipping in the United Kingdom. Background In the United Kingdom, acts of Parliament remain in force until expressly repealed. Blackstone's '' Commentaries on the Laws of England'', published in the late 18th-century, raised questions about the system and structure of the common law and the poor drafting and disorder of the existing statute book. In 1806, the Commission on Public Records passed a resolution requesting the production of a report on the best mode of reducing the volume of the statute book. From 1810 to 1825, ''The Statutes of the Realm'' was published, providing for the first time the authoritative collection of acts. By the early 19th century, British customs law, relating to trade, navigation, the import and export of goods, and the collection of customs revenue, had become increasingly intricate ...
