Method for estimating cool down in a subsea oil and gas production system, which system includes at least one piping or equipment. The method includes the steps of, at shut down of the production in the system; obtaining data from CFD cool down analysis results for a range of temperatures of production media in the system; obtaining data from a temperature sensor in the system; and estimating the actual coldest temperature in the system from the CFD analysis results obtained based on data from the temperature sensor.
