Ships are designed for carrying of cargoes. Tankers carry liquid cargoes such as crude oil, diesel, LPG LNG, Lubricating oil and Naphtha. General Cargo vessels carry cargoes such as bulk, steel, machinery cases and other general items. Bulk Carriers carry cargoes such as grains, coal, iron ore bulk. Container Ships carry containers on deck and inside holds. Ro-Ro vessel carry roll on roll cargoes whereas pure car carriers carry only cars inside the cargo spaces. Passenger vessels on other hand are solely designed for the carriage of passengers.
TYPES OF SHIP
While liquid cargo is pumped into the ships by huge pumps through pipelines, the general cargo which is in the form of cases, bales, bags, boxes, etc. is loaded into the ships holds through openings on deck called hatchways. The cargo operation of solid cargoes is either done by ship or shore gear.

TANKER VESSEL CARGO PUMP ARRANGEMENT
From the Warehouses on the berth, the cargoes are loaded onto the ship by means of slings, snorter nets, trays, etc. Grabs or conveyor belts load bulk cargoes such as Ores, Coals, Grains or Fertilizer.
Special cranes, called gantries, usually load containers but just like general cargoes, the ships cran shore cranes or ship's derricks may also load them.
