Multi-purpose ships are designed to carry a number of types of cargo :
- Bulk Cargoes (e.g. grain, or minerals)
- Neo-bulk Cargoes (e.g. blocks of granite; steel bars; rolls of paper)
- Containers (on deck or perhaps in a specially designed hold)
- Break-bulk Cargoes (e.g. bags of rice; boxes of vehicle parts; bales of wool; machinery; etc.)
- Liquid Cargoes – small amounts of liquid cargoes are sometimes carried in the deep tanks or other tanks (See earlier diagram.)
They usually have tweendecks in some holds, while other holds that do not have tweendecks are suited to the carriage of bulk cargoes.
They also have cranes to handle the cargo that they carry. Some multi-purpose ships have heavylift cranes that can lift large machines, railway locomotives, powerstation parts, or mining equipment.
Sometimes these are called General Cargoships or simply Freighters.
