About NDTest

NDTest OÜ is a specialized maritime inspection and Non-Destructive Testing company headquartered in Tallinn, Estonia. Since our founding in 2020, we have established ourselves as a trusted partner for shipowners, ship management companies, shipyards, and classification societies worldwide.

Our core mission is straightforward: deliver class-compliant, reliable maritime inspection and NDT services that help our clients understand and manage their vessel's structural condition with confidence. We combine technical expertise, practical maritime experience, and professional standards to solve the critical problem that many shipowners face—uncertainty about steel condition before dry docking.
