“…The (14) and (15) there can be observed that for rising of the intake air in amount of 6 [°C] (for example: from -3 [°C]to +3 [°C]) is needed a compressed airwith a mass flow equal with 1.32 [kg/s] from the LP system (but this amount of mass flow is not allowed to be extracted from the gas turbine LP compressor because it represented about 8.57 [%]from the total intake air mass flow) but, at the other hand the anti-icing can be achieved by using compressed air from the HP systemwith mass flow equal with 0.75 [kg/s] which is about 4.48[%]from the total intake air mass flow.…”

Vessels that have navigation routes in areas with ambient temperatures that can drop below + 5 [°C], with a relative humidity of over 65%, will have implemented technical solutions for monitoring and combating ice accumulations in the intake routes of gas turbine power plants. Because gas turbines are not designed and built to allow the admission of foreign objects (in this case - ice), it is necessary to avoid the accumulation of ice through anti-icing systems and not to melt ice through defrost systems. Naval anti-icing systems may have as a source of energy flow compressed air, supersaturated steam, exhaust gases, electricity or a combination of those listed. The monitoring and optimization of the operation of the anti-icing system gives the gas turbine power plant an operation as close as possible to the normal regimes stipulated in the ship's construction or retrofit specification.

Ships have always needed ballast to operate successfully. Ships have always carried solid ballast which was found in form of rocks, sand and many other heavy materials. These were loaded and unloaded when the cargo loading or the discharge operation was finished. This method helpeded maintaining the stability of the ship and its seaworthiness. The main idea of this paper is to realize a complex analysis of tracing the shapes and the stability of ship and sizing of ballast tanks.

Starting from the reality of our times, namely that the maritime and river transports are the cheapest, but also the most long-lasting ones regarding the current types of transport, this paper aims at new perspectives regarding the future of the use of both civil and military ships. Along with other objects and processes, ships must learn to adapt to a rapid changing world. The following issues will be considered: (1) Creating a picture of the future, as plausible as possible, taking into consideration even the pandemic times. (2) The way in which shipping will be positioned in the future. The role shipbuilding may play on the scale of the large global players, taking into account the demographic and economic charts (population growth and life expectancy, involvement in the workplace etc.). (3) What will happen to the old military ships in the event of demilitarization? (4) What would the floating homes and communities of the future look like? In conclusion, reconversion of old (military) ships in civilian transportation and/or mobile dwellings would be a good approach from the point of view of economics and human resources.
