This Concept Map, created with IHMC CmapTools, has information related to: installation of propulsion unit, condensed on the tubes of the sea water cooled main condenser then pump up to a dearator, dearator using extraction pumps the feedwater is then, close system with superheated steam inlet condition of 59 bar at 510°c the quantity of steam is controlled by hydraulically operated 'manoeuvring valves', the feedwater is then fed to the boiler, Steam Turbine Installation is done by high pressure (HP) and low pressure (LP) turbines driving a single propeller shaft line through a double reduction gear box., hydraulically operated 'manoeuvring valves' then steam expand through HP turbine exhaust to inlet of LP turbine, steam expand through HP turbine exhaust to inlet of LP turbine low graded steam is then condensed on the tubes of the sea water cooled main condenser, high pressure (HP) and low pressure (LP) turbines driving a single propeller shaft line through a double reduction gear box. it is a close system with superheated steam inlet condition of 59 bar at 510°c, dearator is use for removing air for feedwater and provides a buffer for load changes, boiler using high pressure turbine driven feed pumps via feed water heaters
