River sea ship
A special type of ship that was developed in the late 19th century is called a river-sea ship or Rhine-sea ship ( English Sea-river coaster ) .
description
Based on ship types specially designed for certain routes, such as the Flatiron Collier , a new type of ship was developed as a modification of a coaster , the river-sea ship, until the 1970s . These ships, which are still in use today, can be used both in coastal shipping , in particular in the so-called England and Iberian coastal shipping , and in inland shipping . In contrast to pure sea-going vessels and coasters to the river-sea well that can bridge with hydraulic assistance by up- lifting cylinders and shut down so that a passage of low bridges is possible inland districts.
The Rhine-See ship type is a special case, as the well-developed river also allows ships with a single superstructure deck to be operated. The dimensions of these ships therefore differ considerably from those of inland vessels. The former are sometimes shorter, but much wider and mostly have a greater depth. Further differences to a barge are that they have a higher freeboard of 0.5 to 2 meters when unloaded , as well as in the seaworthy construction, which also has to withstand the harsher conditions at sea. The first ships of this type were built in 1935 for the Franz Haniel shipping company in Duisburg.
River-sea ships are built as bulkers, container ships (feeder ships) or tankers.
