The reefer is a type of ship typically used to transport perishable commodities which require temperature-controlled transportation, mostly fruits, meat, fish, vegetables, dairy products and other foodstuffs.

Reeferships may be split into two categories:

  1. Sidedoor vessels have sidedoors that is lowered to the quay and serve as loading/discharging ramps for the forklifts. In the rear of the sidedoor there is a double pallet elevator, which brings the cargo to the respective decks. This special design makes the vessels particularly well suited for short distance trade.
  2. Conventional vessels have a traditional cargo operation with hatches and cranes/derricks well suited for the handling of palletized and loose cargo.

A major use of refrigerated cargo hold type ships was for the transportation of bananas but has since been replaced by refrigerated containers that have a refrigeration system attached to the forward end of the container. While on a ship this is plugged into a 220 VAC outlet that ties into the ships power generation. Many ships are limited by the amount of refrigeration containers they can carry due to the lack of refrigeration outlets or insufficient generator capacity. Each “reefer” container has its own breaker switch that allows it to be connected/disconnected in adverse weather with the power off. A quay, pronounced key, is a wharf or bank where ships and other vessels are loaded. ... A forklift that is extended halfway. ... A tower crane with a pivoted main boom Cranes on the Shenska River, Cherepovets, Russia A crane is a tower or derrick equipped with cables and pulleys that is used to lift and lower materials. ... A derrick is a lifting device composed of one mast or pole which is hinged freely at the bottom. ...

Refrigerated cargo is a key part of the income for a shipping company. Refrigerated containers are mostly carried above deck as they have to be checked for proper operation, they may have to have a major part such as a compressor fail which has to be replaced, or they may need to be unplugged quickly as in the event of a fire. As such, this means no provisions for refrigerated cargo power connections are made below the hatch covers that enclose the top of the hatches aboard a ship. Although modern containervessels stow the reefercontainers in cellguides with inspection walkways beside. That way reefercontainers can be carried in the holds as wel.

There are also refrigeration systems that have two compressors for very precise and low temperature operation, such as transporting a container full of blood to a war zone. Containers of shrimp, caviar, and blood are among the most expensive refrigerated items.

Ship - Academic Kids (2438 words)
One can measure ships in terms of overall length, length of the waterline, beam (breadth), depth (distance between the crown of the weather deck and the top of the keelson), draft (distance between the highest waterline and the bottom of the ship) and tonnage.
Before mechanisation, merchant ships always used sail, but as long as naval warfare depended on ships closing to ram or to fight hand-to-hand, galleys dominated in marine conflicts because of their maneuverability and speed.
A few ships have used nuclear reactors, but this is not a separate form of propulsion; the reactor heats steam to drive the turbines.
Refrigerated Cargo Ships / Reefers (978 words)
Reefers are so called because they are refrigerated ships designed to carry frozen or chilled cargo, such as bananas, various types of fruit, orange concentrate, meat and fish.
Reefer ships are effectively large refrigerators, heavily insulated and shuttered with bright metal that prevents taint and is easy to clean.
Below the decks a reefer ship resembles a large modern warehouse, and cargo is usually carried and handled in palletized form, moved about on conveyors or by electric fork lift trucks.
