A container ship 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.
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
A boat or ship engaged in the tramp trade is one which does not have a fixed schedule, itinerary nor published ports of call, and trades on the spot market as opposed to freight liners. A steamship engaged in the tramp trade is sometimes called a tramp steamer; similar terms, such as tramp freighter and tramper, are also used. Chartering is done chiefly on London, New York, and Singapore shipbroking exchanges. The Baltic Exchange serves as a type of stock market index for the trade.
The Baltic Exchange is a membership organisation for the maritime industry, and freight market information provider for the trading and settlement of physical and derivative contracts.
A bareboat charter, or demise charter, is an arrangement for the chartering or hiring of a ship or boat for which no crew or provisions are included as part of the agreement. Instead, the people who rent the vessel from the owner are responsible for taking care of such things. The act is commonly known as bareboating or bareboat charter.
"Demurrage" in vessel chartering is the period when the charterer remained in possession of the vessel after the period normally allowed to load and unload cargo (laytime). By extension, demurrage refers to the charges that the charterer pays to the ship owner for its delayed operations of loading/unloading. Officially, demurrage is a form of liquidated damages for breaching the laytime as it is stated in the governing contract. The demurrage sometimes causes a loss to the seller as it increases cost of the total freight.
A third mate (3/M) or third officer is a licensed member of the deck department of a merchant ship. The third mate is a watchstander and customarily the ship's safety officer and fourth-in-command. The position is junior to a second mate. Other duties vary depending on the type of ship, its crewing, and other factors.
Bulk cargo is commodity cargo that is transported unpackaged in large quantities.
Shipbroking is a financial service, which forms part of the global shipping industry. Shipbrokers are specialist intermediaries/negotiators between shipowners and charterers who use ships to transport cargo, or between buyers and sellers of vessels.
Chartering is an activity within the shipping industry whereby a shipowner hires out the use of their vessel to a charterer. The contract between the parties is called a charterparty. The three main types of charter are: demise charter, voyage charter, and time charter.
A freight rate is a price at which a certain cargo is delivered from one point to another. The price depends on the form of the cargo, the mode of transport, the weight of the cargo, and the distance to the delivery destination. Many shipping services, especially air carriers, use dimensional weight for calculating the price, which takes into account both weight and volume of the cargo.
Worldscale is a unified system of establishing payment of freight rate for a given oil tanker's cargo. Worldscale was established in November 1952 by London Tanker Brokers' Panel on the request of British Petroleum and Shell as an average total cost of shipping oil from one port to another by ship. A large table was created as result.
In general, technical management is the systematic efforts used in the deployment of a system or process and in balancing its cost, effectiveness and supportability during its life cycle.
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets.
A pumpman is an unlicensed member of the Deck Department of a merchant ship. Pumpmen are found almost exclusively on tankers, and on oil tankers in particular. Variations on the title can include chief pumpman, QMED/pumpman, and second pumpman.
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used.
Affreightment is a legal term relating to shipping.
A marine loading arm, also known as a mechanical loading arm, loading arm, or MLA is a mechanical arm consisting of articulated steel pipes that connect a tankship such as an oil tanker or chemical tanker to a cargo terminal. Genericized trademarks such as Chiksan are often used to refer to marine loading arms.
The international shipping industry can be divided into four closely related shipping markets, each trading in a different commodity: the freight market, the sale and purchase market, the newbuilding market and the demolition market. These four markets are linked by cash flow and push the market traders in the direction they want.
The cargo control room, CCR, or cargo office of a tankship is where the person in charge (PIC) can monitor and control the loading and unloading of the ship's liquid cargo. Prevalent on automated vessels, the CCR may be in its own room, or located on the ship's bridge. Among other things, the equipment in the CCR may allow the person in charge to control cargo and stripping pumps, control and monitor valve positions, and monitor cargo tank liquid levels.
