For decades, Gertsen & Olufsen has helped shipowners, shipyards, and operators run cleaner, quieter, and more reliable vessels. Founded in 1945 and now part of the G&O Maritime Group, the company’s two flagship brands—G&O Compensators and G&O Bioreactors—deliver tangible operational value: eliminating harmful engine- and propeller-induced vibrations and ensuring compliant, efficient onboard wastewater treatment without dilution or consumables.

Headquartered in Kongens Lyngby, just north of Copenhagen, Denmark, G&O benefits from a modern group hub inaugurated in 2024 to support growth, R&D collaboration, and closer customer partnerships.
