Safe navigation in the sense of complete technical correctness of the ship, protection of human life, but also the marine environment has been in the center of attention since the very beginning of the development of shipping and shipping. Precisely for this purpose, a significant number of international documents and agreements in the form of conventions, memoranda, codes, regulations and laws were adopted, which were adopted by almost all important maritime countries. The key to protecting the safety of the ship, the crew and the environment is certainly the performance of various forms of ship inspection, one of the most important of which is inspection and supervision by the flag state, i.e. by an inspector authorized by the administrative body of the state under whose flag the ship sails. It is crucial that during each inspection, regardless of the type and activity for which the ship is used within the maritime area, a pre- established protocol is followed by which all relevant categories are inspected to determine the formal, technical and safety correctness of the ship. If, however, deficiencies are noticed, they must be removed within the stipulated time limits and according to the regulations, all with the aim of not imposing sanctions on ship owners or their managers and the vessel itself.
