On an offshore platform or on board a vessel, downtime is expensive. Every minute a crane, winch or drilling installation isn’t working costs money and puts the schedule under pressure. Yet maintenance on hydraulic systems is still often only taken seriously once something breaks. At DTA, we prefer to flip that around: prevention is cheaper than repair.
Why hydraulic systems at sea need extra attention
Hydraulic systems onshore have it relatively easy. At sea, that’s a different story. Saltwater, extreme pressure differences and continuous use mean components wear out faster. Contamination of the hydraulic fluid with water, salt or particulates leads to erratic operation, internal wear and eventually leaking seals. Without a proper maintenance plan, small issues pile up into major, costly failures.
What preventive maintenance looks like in practice
Fluid analysis. Regularly checking for water ingress and contamination stops small issues from turning into expensive repairs.
Proper filtration. A good filtration system with clear indicators keeps contamination out before it causes damage.
Visual inspections. Early signs such as rust, pitting or minor leaks are often easy to fix, provided you catch them in time.
Protection against shock loads. Accumulators help absorb pressure spikes, significantly extending the lifespan of cylinders and motors.
Fixed maintenance intervals. Rather than waiting for a failure, you work to a schedule that matches the load and environment of your installation.
