A process for the conversion of oil feeds for the production of low sulphur fuels by fixed bed hydrodemetallization of the feed using an upstream system of fixed bed swing reactors; fixed bed hydrocracking of the hydrodemetallized effluent in the presence of a hydrocracking catalyst; separation in order to obtain a heavy fraction; hydrodesulphurization of the heavy fraction in which hydrogen is reinjected.
