“…The technical literature pays considerable attention to the description of FPSO technical systems, including the use of gas turbine engines [3; 5; 6]. The review of work [7] indicates applicability of: three 27.5 MW gas turbine generators on FPSO's Pioneiro de Libra, four 36 MW gas turbine generators on FPSO's Cidade de Itajaí, three 21 MW gas turbine generators on FPSO's Armada Olombendo, two 16 MW gas turbine generators on FPSO's Global Producer III, 4 MW gas turbine generators on FPSO's Dhirubhai-1, two 42 MW gas turbine generators on FPSO's TRITON.…”

The analysis of the possibilities of organization of low-emission associated gas combustion in the combustion chamber of a gas turbine engine with a capacity of 25 MW, which works as part of floating production, storage and offloading (FPSO) system is carried out. One of the significant problems that solved when using the gas turbine technology at FPSO is to satisfy the international environmental requirements, especially for emissions of toxic components, such as carbon and nitrogen oxides. An effective way of organizing a workflow in a gas turbine low-emission combustion chamber operating on different gaseous fuels is proposed. In order to increase the efficiency of the processes in the gas turbine chamber, it is proposed to use the ideas of pre-mixing of gaseous fuels with air in axial-radial swirlers, as well as significant leaning of the fuel-air mixture in the volume of the combustion chamber. A mathematical model of a low-emission gas turbine combustion chamber has been developed, which allows predicting the environmental parameters of a fuel-burning device when using associated gas. Three-dimensional mathematical model of gaseous fuels combustion in a low-emission gas turbine combustion chamber contains the following equations: continuity, conservation of momentum and energy, transfer of chemical components, formation and decomposition of nitrogen oxides. The obtained results showed certain deterioration in the environmental parameters of the combustion chamber when switching from natural to associated gas and the need for further modification of the combustion chamber with lean and partially premixed mixture of fuel and air when using associated gas on the FPSO vessels.

Substantiation of using non-circular plain shaped surfaces to increase the compactness of power plants is presented. The criterion of thermohydraulic compactness is justified, which takes into account the layout and arrangement of heat transfer elements and their thermohydraulic efficiency.To simulate heat movement and transfer processes in elements of power plants, the computational fluid dynamics method is used. Verification is carried out with available literature data, the discrepancy of results does not exceed 2.4 %. For single elliptical and planeoval shapes, there is a local maximum of efficiency, achieved at the axis ratio of 2.5 for elliptical and 2.75 for plane-oval. Studies of the change of the heat transfer coefficient in the tube bank rows are carried out. For the elliptical tube bank, heat transfer is stabilized from the fifth row. Heat transfer surfaces of circular, elliptical and plane-oval tubes with different combinations of geometric characteristics are considered. It is found that on the basis of elliptical tubes it is possible to reduce the volume of the heat transfer surface and increase the compactness of the entire power plant by 18.3 % compared to circular tubes and 2.4 % compared to flat-oval ones. Dimensionless indices of mass, volume, functional efficiency and service life of the heat exchanger are substantiated, allowing them to be compared as part of various power plants. It is advisable to continue studies of the features of heat transfer processes in close, with the relative longitudinal and transverse pitch ratio less than 1.5, banks of elliptical tubes with an axis ratio of 2.5

The article considers the methodological aspects of the theoretical investigation of marine power plants with thermochemical fuel treatment. The results of the study of the complex influence of temperature, pressure, and the ratio of steam / base fuel on the thermochemical treatment efficiency are presented. The adequacy of the obtained regression dependences was confirmed by the physical modelling of thermochemical fuel treatment processes. For a gas turbine power complex with a thermochemical fuel treatment system, the characteristics of the power equipment were determined separately with further merging of the obtained results and a combination of material and energy flow models. Algorithms, which provide settings for the mathematical models of structural and functional blocks, the optimisation of thermochemical energy transformations, and verification of developed models according to the indicators of existing gas turbine engines, were created. The influence of mechanical energy consumption during the organisation of thermochemical processing of fuel on the efficiency of thermochemical recuperation is analysed.
