Preventive maintenance on ships consists of a set of systematic practices aimed at preserving the structure, systems and equipment. Unlike corrective maintenance, which takes place after a failure, preventive maintenance anticipates potential problems, reducing downtime and operational risks.

Effective maintenance strategies include regular inspections of hulls and metal structures to identify corrosion and cracks before they jeopardise the ship’s integrity. Mechanical systems such as engines, generators and propellers must be monitored to prevent excessive wear and critical failures.

The implementation of a Computerised Maintenance Management System (CMMS) allows precise monitoring of the ship’s components, ensuring that periodic overhauls are carried out in accordance with the regulatory standards of the shipping industry. In addition, preventive maintenance includes the calibration of navigation and communication equipment, which is essential for the safety of the ship.

Lubricating shafts and bearings, checking the integrity of pipework and analysing energy efficiency are also indispensable. Sustainable measures, such as applying anti-fouling paints to the hull, help reduce fuel consumption and improve hydrodynamic performance.

Investing in preventive maintenance not only extends the life of the ship, but also optimises costs, increases crew safety and ensures compliance with international regulations. A well-structured maintenance programme is the key to an efficient and reliable maritime operation.
