The Operational Transfer Path Analysis (OTPA) method is the subject of research in this paper. After a brief review of it's theory, the methodology is applied to a ship with a double engined, directly driven, power train. With the additional presence of a generator set, this test candidate makes a good example for the OTPA's simultaneous identification of multiple excitation sources in the perceived cabin's sound level. The ship is measured in two configurations to illustrate how alterations to the ship's design influences the ship's performance.
