摘要： The invention relates to an arrangement for improving load response in a marine vessel, which vessel comprises a propulsion system (1) including an internal combustion engine (2), a generator (3), a main switchboard (4), and an electric propulsion unit (5). A power bank (6) is connected to the main switchboard (4), whereby the power bank (6) is arranged to store additional electric energy supplied by the generator (3) by way of the main switchboard (4). The additional energy stored in the power bank (6) is arranged to be used together with the electric energy supplied by the generator (3) in order to increase the load response to the electric propulsion unit (5) at a given time.
