"Technology of transport of Ro-Ro cargo by sea" is a work that describes Ro-Ro ships, their history, division, characteristics and equipment for access to the ship with all required funds for tying and securing the cargo. Besides that, it is important to mention the ship's ramps, without this system would be much heavier and slower, and could not allow such a specific way of manipulation, which is an extremely important factor. Ro-Ro system („Roll on-roll off“) was invented in the 60's of the 19th centurywhen the mass construction of such ships began, which unlike vertical loading or unloading, receive cargo horizontally with the help of wheels. Through various investments in Ro-Ro ships and terminals it has contributed to the emergence of one of the most efficient and fastest transhipment systems. The future and further progress of Ro-Ro tehnology depends on the modernization of the system. The assignment consists of introduction, conclusion, 8 chaters and whit its corresponding subchapters, pictures, bibliography and list of pictures.
