A naval vessel operates as efficiently as its weakest system, and hydraulics power many onboard devices. That is why ETMAL, a Gdynia-based company that has been providing maintenance, repair and diagnostic services to the Polish Navy for over 20 years, highlights the importance of reliable systems for the operational readiness of vessels. Knowledge of the requirements of military units allows specialists to combine technical diagnostics with maintenance planning, equipment condition reporting and compliance with required procedures. For shipowners and vessel operators, this means fewer unexpected issues during operation, while lasting reliability does not come from emergency repairs, but from regular diagnostics, planning and documentation.
What does operational readiness mean in technical practice?
From a technical perspective, it means the ability of key mechanisms to operate at any time, without unexpected downtime. It requires continuity of equipment operation, predictable technical condition and maintenance planning in a way that ensures servicing does not interfere with the vessel’s duties. The earlier wear is detected, the greater the chance that repairs can be carried out as scheduled rather than in an emergency situation.
Hydraulics at the heart of onboard mechanisms
Hydraulic drives are used in cylinders, winches, anchor and mooring windlasses, crane systems and many other onboard devices. Pumps, valves and lines operate under pressure, and their condition depends, among other things, on oil cleanliness and system tightness. When one component fails, the effects can be felt throughout the entire system, from movement precision to operational safety. That is why hydraulic systems require attention not only during overhauls, but also during everyday operation.
Service that prevents problems, not just repairs them
Effective servicing starts with diagnostics: assessing equipment condition, taking measurements and analysing component wear. Only then can the required work be planned and its scope determined. ETMAL has a mobile hydraulic system diagnostic workshop and equipment for measuring oil contamination as well as flushing and filtering hydraulic systems, allowing many tasks to be carried out directly on board. Consulting services are an important complement, helping to plan subsequent inspections and reduce the risk of failure. The operator also receives clear feedback: what is functioning correctly, which systems should be prioritised and when further work should be scheduled.
Sector requirements: licences, confidentiality and documentation
Working for the defence sector requires more than technical expertise. The company holds military concessions, while the nature of such cooperation requires discretion and strict compliance with procedures. That is why ETMAL does not disclose details of individual assignments, and every stage of the work is documented in service reports. The ISO 9001:2015 quality management system and ISO 45001:2018 occupational health and safety management system help organise these activities and facilitate their supervision.
