hooldamine

Hooldamine, in Estonian usage, denotes the process of maintaining and preserving assets to ensure continuous operation. It includes planned and reactive activities aimed at preventing failures and extending service life. The term is used across industries such as manufacturing, energy, transport, and building management.

Maintenance can be preventive (scheduled servicing at regular intervals), predictive (based on condition monitoring data), or corrective (performed after a failure). It also includes routine servicing, lubrication, calibration, replacement of worn parts, cleaning, and safety checks. The goal is to keep equipment and facilities functioning safely, efficiently, and in compliance with standards.

Organizations use maintenance management systems (CMMS) or enterprise asset management (EAM) tools to track asset inventories, work orders, maintenance histories, and spare parts. This data supports optimization of inspection intervals, resource planning, and lifecycle cost management.

Practical practices include regular inspections, lubrication, cleaning, adjustments, parts replacement, and performance testing. Condition monitoring methods such as vibration analysis, thermography, lubrication analysis, and motor current signature analysis help inform maintenance decisions. Predictive maintenance relies on these methods to forecast failure risk.

Benefits include reduced unexpected downtime, extended asset life, improved safety and compliance, and lower total cost of ownership. Challenges include budget limitations, aging or complex assets, data quality, and the need for skilled personnel. Emerging trends involve IoT-enabled sensors, remote monitoring, data analytics, and digital twins to optimize maintenance planning and execution.
