Most terminals have direct rail access and container storage areas, and are served by highway carriers.

The operator invests in cargo-handling equipment (forklifts, cranes, etc), hires longshore laborers to operate such lift machinery and negotiates contracts with ocean carriers (steamship services) to handle the unloading and loading of ship cargoes. (See also: operating port.)

LASH: These 900-foot-long ships carry small barges inside the vessel. LASH stands for Lighter Aboard Ship. Just as cargo is transported by barge from the shallower parts of the Mississippi River to the Port of New Orleans for export aboard ocean-going ships, LASH barges are lifted into these unusual ships. Overseas, the ship can discharge clusters of barges in the open waters. Then several towboats will assemble the barges into tows bound for various ports and inland waterways, without the ship having to spend time traveling to each port.

Charterhire:  Money paid to a vessel’s owner by the charterer for the use of a vessel under a time charter or bareboat charter. Payments for timecharters are usually made during the course of the charter every 15 or 30 days in advance or in arrears by multiplying the daily charter rate times the number of days and, under a time charter only, subtracting any time the vessel was deemed to be off-hire. Payments for voyage charters are payable upon the discharge of cargo. Under a bareboat charter such payments are usually made monthly and are calculated on a 360 or 365 day calendar year basis.

Without valid class certificates, vessels deemed unseaworthy and cannot obtain insurance coverage or allowed to sail. Prominent classification societies are the American Bureau of Shipping (ABS), Bureau Veritas (BV), China Classification Society (CCS), Det Norske Veritas’ (DNV) which recently merged with Germanischer Lloyd (GL), Korean Register of Shipping (KR), Lloyd’s Register of Shipping (LR), Nippon Kaiji Kyokai (ClassNK), Registro Italiano Navale (RINA).

Contract of Affreightment:  A contract of affreightment, or COA, relates to the carriage of specific quantities of cargo with multiple voyages over the same route and over a specific period of time which usually spans a period of time possibly even a number of years. A COA does not designate the specific vessels or voyage schedules that will transport the cargo, thereby providing both the charterer and ship owner greater operating flexibility than with voyage charters alone. The charterer has the flexibility to determine the individual voyage scheduling at a future date while the ship owner may use different ships to perform these individual voyages. As a result, COAs are mostly entered into by large fleet operators such as pools or ship owners with large fleets of the same vessel type. All of the ship’s operating, voyage and capital costs are borne by the ship owner while the freight rate normally is agreed on a per cargo ton basis.

Combination Carrier: Ship capable of carrying different types of cargo, thereby achieving a more uniform flow of shipments.  Typically termed OBO, an abbreviation for oil, bulk, ore, which means that the vessel is designed for cargoes of these and other bulk products.

Time charter: A time charter is a contract under which a charterer pays a fixed daily hire rate on a semi-monthly or monthly basis for a fixed period of time for use of the vessel. Subject to any restrictions in the charter, the charterer decides the type and quantity of cargo to be carried and the ports of loading and unloading. The charterer pays the voyage related expenses such as fuel, canal tolls, and port charges. The vessel-owner pays all vessel operating costs such as the management expenses and crew costs as well as for the capital costs of the vessel. Any delays at port or during the voyages are the responsibility of the charterer, except for certain specific exceptions such as loss of time arising from vessel breakdown and routine maintenance.

Time Charter Equivalent (TCE) rates:  Time charter equivalent, or TCE, rates, are a standard industry measure of the average daily revenue performance of a vessel. The TCE rate achieved on a given voyage is expressed in U.S. dollars/day and is generally calculated by subtracting voyage expenses, including bunkers and port charges, from voyage revenue and dividing the net amount (time charter equivalent revenues) by the number of days in the period.

For a bareboat charter, the charterer pays vessel operating costs.

Vessel Response Plan (VRP): A detailed plan of action for responding to a potential oil spill from a vessel in United States waters. The plan has to be submitted to the United States Coast Guard as set out under OPA ’90.

Voyage Charter: A voyage charter involves the carriage of a specific amount and type of cargo from specific load port(s) to specific discharge port(s), subject to various cargo handling terms. Most of these charters are of a single voyage nature between two specific ports, as trading patterns do not encourage round voyage trading. The owner of the vessel receives one payment derived by multiplying the tons of cargo loaded on board by the cost per cargo ton, as agreed to transport that cargo between the specific ports. The owner is responsible for the payment of all expenses including voyage, operating and capital costs of the vessel. The charterer is typically responsible for any delay at the loading or discharging ports.
