This paper presents research results on CO2 emissions originating from maritime vessels with various main engine settings. The impact (i.e., the volume and amount) of gas emissions into the environment is shown, along with the characteristics of the marine fuel used. This research was carried out on a container vessel sailing on a fixed route between Rotterdam and St. Petersburg. It covered mainly two different engine operations, at 124 RPM and 100 RPM settings, in the Kiel Canal area. The purpose of this study is to demonstrate that the engine setting of 100 RPM compared to the same voyage through the Kiel Canal, with an engine setting of 124 RPM, leads to a significant reduction of CO2 emissions. Though proving such a thesis seems to be evident, the analysis in the paper shows that, in practice, mainly due to time constraints and engineers’ assumptions of engine technical status, the higher speeds are still preferred over lower ones. In studies not related to passive use or active methods, only specific and simplest methods of obtaining CO2 emissions are presented.

The International Maritime Organization (IMO) introduces, adopts, and implements new instruments, such as conventions, resolutions, and guidelines, to prevent and minimize the number and severity of accidents involving ships at sea. The results of international maritime safety requirements introduced in recent years are presented in this paper. The impact of these regulations on ship safety improvement in European marine waters was determined via an analysis of accidents over a seven-year period of 2014–2020. The analysis was based on the classification of accidents by their severity, by the type of ship involved, and by the identified causes or contributing factors. Evident, still existing “weak points” of maritime safety monitoring are emphasized, such as low reporting of incidents and superficial identification of contributing factors. It is worth noting that the technological development of marine electronic systems introduced both positive effects and novel threats to the safety of navigation. An example is an uncritical overreliance on technology and information provided via electronic means and sensors. In this context the usage of integrated, digitized bridge systems in contemporary maritime vessels and future remote control systems was stressed.
