    The modern simulation software includes an impact of forces acting on the ship hull. One of the mostsignificant forces is sea waves acting. The mathematical model allows simulation of ship motions in irregularsea wave area, both – at deep and shallow waters. The wave surface model enables simulation of the waveelevation in compliance with wave spectrum occurring in various conditions. The paper presents generaldescription of the sea wave model used in maritime simulators. An example of such simulators is used at the laboratory of the Naval University of Gdynia, where it is operated basing on NT-Pro 5000 software by Transas Marine. The latest version of simulation software gives a possibility to select the wave spectrum. Selection of the waving type, depending on sea area location, makes the ship movement more reliable. This is an important element in testing the ships behavior process

    Traditional methods for assessing threats were ekological but today are ineffective. It is proposed to address this problem based on the classic balance method, known as the law of conservation of matter Lomonosov– Lavoisier, according to which the total mass of the physical system is preserved for all natural and man-made processes, including the procedures for processing and disposal

    This article presents law requirements of the toxic emission to the atmosphere on example usually measured components during the analysis of exhaust gases. The paper describes the impact of NOx, SOx and COx on the atmosphere and also ways to reduce their emission.
