The need to save ships, cargo and people 
in distress at sea is inextricably linked 
with the development of navigation, the history 
of which goes back centuries and millennia. Marine emergency rescue practice has developed 
means and methods of rescue. Many ships sank, 
and their cargo and metal parts, including anchors and cannons, were of considerable value 
at that time. The need to raise them after shipwrecks, especially in coastal waters, forced, for 
example, to solve diving problems, and the need 
to prevent accidents – emergency rescue tasks. 
Helping each other at sea in times of danger was 
already a tradition of seafaring brotherhood, a 
law of the seafaring comradeship. On the vast 
expanses of the sea, a vessel in danger calls out 
to the experienced and the brave – those who 
seek the reward of salvage rights.
