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 and obtaining insurance, usually for a minimum term of one year. The act is commonly known as bareboating or bareboat charter.
Deadweight tonnage or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew.
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.
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.
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water.
A vessel's length at the waterline is the length of a ship or boat at the level where it sits in the water. The LWL will be shorter than the length of the boat overall as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L is measured from a default load condition.
A shipowner, ship owner or ship-owner is the owner of a ship. They can be merchant vessels involved in the shipping industry or non commercially owned. In the commercial sense of the term, a shipowner is someone who equips and exploits a ship, usually for delivering cargo at a certain freight rate, either as a per freight rate or based on hire. Shipowners typically hire a licensed crew and captain rather than take charge of the vessel in person. Usually the shipowner is organized through a company, but also people and investment funds can be shipowners. If owned by a ship company, the shipowner usually performs technical management of the vessel through the company, though this can also be outsourced or relayed onto the shipper through bareboat charter.
Length overall is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth.
Length between perpendiculars is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars.
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.
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.
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criterion measured relative to the ship's load line, regardless of deck arrangements, is the mandated and regulated meaning.
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.
Ship management is the activity of managing marine vessels. The vessels under management could be owned by a sister concern of the ship management company or by independent vessel owners. A vessel owning company that generally has several vessels in its fleet, entrusts the fleet management to a single or multiple ship management companies. Ship management is often entrusted to third parties due to the various hassles that are involved in managing a ship. For instance, ships could be considered as large factories that travel across seas under various weather conditions for several days at a stretch. These vessels are equipped with several types of machinery that require appropriate maintenance and the associated spares on board. In the scenario of a vessel lacking adequate maintenance, this could lead to the breakdown of the equipment in the middle of a voyage at sea. A breakdown could be an expensive affair. A second scenario would be – a vessel is continuously on the move or under some sort of activity and hence requires a competent crew. The documents of the crew need to comply with international regulations, their transportation to and from the vessel must be arranged for, their competencies must align with the requirement of the vessel and must complement the skillsets of the existing onboard crew. Hence several parameters must be considered which is a tedious job.
