A rainproof cap is installed on the top of the gas turbine exhaust pipe of an offshore oil platform,which causes the high-temperature flue gas emitted during the operation of the gas turbine to be ejected downward and spread to all around.Due to the limitation of offshore platform space,the high-temperature flue gas in some wind directions is directly blown to the nearby crane and workover rig,causing the hydraulic system of the related equipment to fail due to the heating and high temperature alarm,and also bringing potential safety hazards to its construction operations.Taking the gas turbine unit as the research object,this paper analyzes the adverse effect of rainwater from the smoke exhaust pipe into the standby turbine unit after removing the smoke exhaust pipe rain cap,and puts forward the design idea of rainwater drainage transformation according to the existing cleaning sewage discharge pipeline of the unit.The relevant pipelines of the existing drainage system of the unit are optimized and reconstructed to realize the automatic discharge of flue water when the gas turbine is shut down,thus avoiding the water from eroding the gas turbine core unit and extending the service life of the unit.
