The paper presents the problems of fighting the noise coming from hydraulic central loading systems with big power installed on modern product and chemical tankers to supply cargo pumps. The structure of a hydraulic central loading system is described along with its components and main noise sources are characterized. Active and passive ways of noise reduction on a technical road are presented as well. All the deliberations have been illustrated on the example of specific solutions of the hydraulic central loading system installed on the product tanker m/t “Helix”, built by the Szczecin Shipyard SA for the Shell-Australia shipowner
