Noise from a ship at anchor sometimes poses problems to humans in the vicinity. The sound from the exhaust of the main generator is the main cause for the noise. This can be managed by installing an active silencer to the main generator. All the noise sources from the ship were analyzed after installing the silencer. The extent of the noise in the ships vicinity were calculated by applying a ray tracing method to all noise sources. The calculation was confirmed as precise, as it indicated 3 dB (A) . Future studies will explore noise from an anchored ship in relation to noise.
