A method for retrofitting an existing pedestal mounted crane (10) with a flywheel energy storage system (50). The method includes providing a flywheel energy storage system comprising a flywheel (51) having an outer diameter and a rotational axis, a flywheel support structure (53) provided with one or more bearings that support the flywheel rotatably relative to the flywheel support structure, and an electric motor-generator (60) coupled to the flywheel. At least the flywheel and at least a part of the flywheel support structure are accommodate in the pedestal, for example in the existing pedestal (11) and/or in a pedestal extender (40) that is optionally mounted on the head (13) of the existing pedestal with the existing slew bearing (14) being removed from said head and a slew bearing (14') then being mounted on a head of the pedestal extender. An electrical circuit (70) is provided between the motor-generator (90) of the flywheel energy storage system and electric motor (60) that drives the hoisting winch (22).
