Key benefits of regular maintenance and preventive servicing:

Preventive servicing helps identify minor defects (wear, corrosion), reducing repair costs;
Maintenance enables advance planning of work and spare parts procurement, avoiding unplanned vessel downtime and related losses due to cargo delays;
Regular lubrication, oil changes, and compliance with operating conditions significantly slow down physical wear of machinery and hull, thereby extending equipment service life;
Regular maintenance ensures compliance with classification society requirements and international conventions, eliminating fines and vessel delays in ports.
