摘要

The system (1) flows heavy oil fuel and distillate fuel from fuel tanks (12,13) in the direction of mixing tank (14) and circulates oil fuel and distillate fuel in a feeder fuel circuit (4). A pump unit (21) flows fuel from mixing tank towards marine diesel engine (2,3) with second volume flow which is greater than the first volume flow. Diesel engine return backs fuel to the mixing tank and draws fuel from fuel tank (13) at third volume flow which is greater than the first volume flow, such that operation of the diesel engine is changed from first fuel type to second type. An independent claim is included for method for operating fuel supply system.
