HOW A RETROFIT WORKS

Retrofitting your existing seal system is easier than you might think. Our retrofit process is designed to fit seamlessly into your scheduled dry dock period, without unnecessary complexity.

 

1. ASSESSMENT & ENGINEERING

We analyze your current seal system and vessel specifications. Our engineers determine the best retrofit configuration, ensuring a perfect fit within your existing installation.

2. CUSTOM MANUFACTURING

All retrofit components are manufactured in-house. Thanks to our modular seal design and extensive raw material stock (90-1150 mm inner diameters), we can ensure short lead times and fast preparation.

3. PLUG & PLAY INSTALLATION

The retrofit solution is designed for easy installation during dry dock. No full system replacement is required, only targeted upgrades of critical components.

4. TESTING & COMMISSIONING

After installation, the system is inspected and tested to ensure optimal performance and compliance with class and environmental regulations.
