The dependency of marine gas turbine on the ambient temperature leads to a decrease of the gas turbine power output in arid areas. Very often gas turbine power output demand is high and the power margins originally designed into the driver , has been exhausted. In such circumstances the inlet air fogging is an effective compensation of gas turbine power. In this paper an analysis of inlet air fogging applicability to marine gas turbine has been conducted. Different areas of ship’s voyage have been taken into account. The use of inlet air fogging in marine gas turbine must be evaluated on the basis of turbine characteristics, climate profile of ship’s voyage, and expectations of gas turbine power augmentation. The authors expect that the considerations provide useful guidance for users of marine gas turbines to decide the feasibility of installing an inlet air fogging system

The use of inlet air fogging installation to boost the power for gas turbine engines is widely applied in the power generation sector. The application of fogging to mechanical drive is rarely considered in literature [1]. This paper will cover some considerations relating to its application for gas turbines in ship drive. There is an important evaporative cooling potential throughout the world, when the dynamic data is evaluated, based on an analysis of coincident wet and dry bulb information. This data will allow ships’ gas turbine operators to make an assessment of the economics of evaporative fogging. The paper represents an introduction to the methodology and data analysis to derive the direct evaporative cooling potential to be used in marine gas turbine power output loss compensation

The paper concerns a propulsion system of merchant ships intended for sailing in the Baltic Sea zone. Suchsystem is to satisfy the ecological requirements determined by relevant international conventions for specialzones to which the Baltic Sea also belongs. The paper draws attention to gas turbine used as a prime moverfor such ships, because it satisfies the ecological requirements and has also other advantages. Application of gas turbine for ship powering does not require exhaust gas to be purified, however it requires fuel oils of a low sulphur content to be used. If the ecological rules impose the using of the fuel oils of similar quality for diesel engines then gas turbine propulsion system will be comparable − also economically (regardingspecific fuel oil consumption cost) − with that of diesel engine. It would be even more favourable ina combine gas turbine /steam turbine system, especially at compound production of electric and heat energy(i.e. COGES systems). In the Baltic Sea zone gas turbines will find application to powering a. o. such shipsas : fast car-passenger ferries, fast cargo ships, special vehicles (hydrofoils, hovercraft, motor yachts)
