In today’s environment of increasing pressure to reduce fuel consumption and emissions of carbon dioxide (CO2) and nitrogen oxides (NOx), the LNG (Liquefied Natural Gas) transportation industry is growing in size and influence. In this context, further efforts are needed to improve the energy efficiency of LNG marine energy power plant. The LNG vessels and their equipment considered in this study have different power consumption requirements depending on the vessel’s mode of operation (loading/unloading, maneuvering, anchoring, at sea, etc.). For each ship mode, where the power plant requirements are the same, the specific fuel consumption (SFOC) and exhaust emissions, NOx and CO2, are compared with a different number of engines in the network to find the optimal number of engines in the network, considering both the safety aspect and the port requirements. An analysis was performed showing the efficiency of the on-board power management system (PMS) in terms of manual load sharing between engines. A comprehensive analysis of the data and its comparison led to the conclusion that the manual distribution of power among the engines is the slightly better solution. The obtained results show that further analysis of the number of engines for a given load with minimum fuel consumption and CO2 and NOx emissions is required.

The promotion of gender equality and women’s empowerment is one of the main goals of the United Nations. The aim of this study is to analyze the gradual change of conservative perceptions about the role of women in shipping. Maritime education and training institutions are fully involved in the process. The Nikola Vaptsarov Naval Academy and the Split University’s Faculty of Maritime Studies are a part of this process of general change in human attitude towards the acceptance of women on merchant ships. Data on female admittance and graduation are collected by both academies. In the period examined, i.e.  2012 – 2018, 129 women were enrolled at and 60 graduated from the NVNA. 281 women were enrolled at and 68 graduated from the Faculty of Maritime Studies. The attitudes of female candidates at the academy Nikola Vaptsarov were studied by means of a questionnaire. The growing number of female candidates at Nikola Vaptsarov’s Navigation, Ship Engineering and Electrician studies proves that a competitive environment was created on a completely new basis, namely the ability of women to work at an equal footing with men in a purely male-dominated profession. This paper opens the door to future research of the recruitment market required to establish the reasons behind skepticism about women on board and the ways to overcome this conservative line of thinking.
