Preservation Services

We provide comprehensive preservation services to ensure offshore assets remain in optimal condition during operation, lay-up, or transit, preventing costly deterioration and extending asset lifespan. Our tailored solutions include corrosion control, humidity management, fluid preservation, system flushing, and periodic equipment rotations, all designed to mitigate degradation and ensure operational readiness. We develop customized preservation plans based on asset type, lay-up duration, and future reactivation needs, incorporating industry best practices for mechanical, electrical, and structural components.

Our approach includes detailed inspections, condition monitoring, and proactive maintenance strategies to identify and address potential issues before they escalate. Whether an asset is in short-term lay-up or long-term preservation, AOS ensures that all critical systems remain protected, functional, and ready for reactivation with minimal downtime. By integrating strategic preservation techniques and periodic reassessments, we help clients reduce long-term costs, improve reliability, and maximize asset value through out its lifecycle.
