• Container ships carry cargo in containers, which are made of steel or aluminium
Roll-on/roll-off ships (RO-RO) are always distinguished by large doors in the hull and by external ramps that fold down to allow rolling between pier and ship.
Heavy-lift ships can transport huge sections of process equipment around the world
Livestock carriers are designed to carry farm animals.
SERVICE SHIPS Cable-layers lay and repair transoceanic cables.
pipe-layers lay pipes
Dredgers deepen and clear waterways.
Icebreakers open lanes for other ships through frozen waters.
Tugboats are designed to assist a large vessel in berthing, unberthing or departing the port or fire fighting.
Offshore supply vessels are designed to support equipment to oil rigs and drilling platforms located in the open seas.
