Combined Gas and Steam Turbine Propulsion on Contemporary Ships

U ovom završnom radu govorimo o brodovima za prijevoz ukapljenog prirodnog plina, plinu kao propulzijskom sredstvu te o kombinaciji plinske i parne turbine kao propulzijskom postojenju takvih tipova brodova. Prirodni plin kao propulzijsko sredstvo zastupljen je samo na brodovima za prijevoz ukapljenog prirodnog plina, ali se nastoji unaprijediti ta tehnologija da se i na druge tipove brodova instalira plinska propulzija zbog same činjenice o smanjenju onečišćenja okoliša i ekonomičnosti plinsko i parno – turbinskog postrojenja. Ovaj završni rad obuhvaća sve podsustave COGES propulzijskog postrojenja, njihove elemente i principe rada glavnih komponenti. COGES propulzijsko postrojenje sa azipodnim propulzorima je tehnologija koja sve više zamijenjuje konvencionalnu dizel-motornu propulziju.In this final work we are talking about ships which are used for transporting liquified natural gas, natural gas as propulsion and combination of gas and steam turbine as propulsion plant these types of ships. Natural gas as propulsion is present only on ships which are used for transporting liquified natural gas, but strive is to upgrade that technology so that other types of ships can be installed with gas propulsion becouse of fact that the gas propulsion is less environment polluter and more economical combined gas and steam – turbine propulsion plant. This final work includes all subsystems of COGAS propulsion plant, their elements and working principles of main components. COGES propulsion plant with azipodded drivers is technology that more and more replace conventional diesel – engine propulsion
