Lubrication checks and oil changes
Condition checks based on operating hours or maintenance planning

Troubleshooting & diagnosis

When separator performance changes or an unexpected issue occurs, fast and accurate diagnosis is essential. Our engineers identify the root cause on site, assess the separator’s condition and provide clear recommendations, helping you decide whether repair or exchange is the most reliable and cost-effective solution.

Corrective on-site repairs

Corrective on-site repairs are focused on fast, practical solutions that restore safe operation without unnecessary delay. Our engineers carry out essential repairs and adjustments directly on location, ensuring your separator performs reliably again and helping you minimize downtime during critical operations.

construction Replacement of seals, gaskets and bearings

Worn seals, gaskets and bearings are among the most common causes of leaks, performance loss and vibration. We replace these components on site using the correct parts and proven procedures to restore reliability and prevent further damage.

build Adjustment of the separator and related equipment

Correct settings are essential for stable separator performance. We adjust the separator and connected systems to ensure proper flow, discharge behaviour and safe operation under the vessel’s actual working conditions.

check Minor mechanical corrections

Small mechanical issues can quickly develop into major failures if left unaddressed. Our engineers perform minor corrections on site to eliminate abnormal wear, reduce vibration and keep the separator running smoothly.

construction Functional testing after maintenance

After any intervention, we verify performance before returning the separator to operation. Functional testing confirms correct assembly, safe start-up and stable running conditions, giving both crew and technical management confidence in the result.

Spare parts & service support

Reliable service starts with the right parts and the right support. KET Marine provides fast access to proven components and practical assistance, ensuring your crew can act quickly and keep separator systems running safely and efficiently, even under time pressure.
