ThreeGenerations
Master Mariners
60+ years of Baltic maritime surveying. DNV-GL certified. Flag state authority for five nations.
Built on the bridge,
not the boardroom
The company started with a choice. Leave the bridge. Stay in the industry.
Three generations of master mariners built JG Marine on what they knew: Baltic waters, Polish ports, the language of cargo and hulls and claims. Maritime surveying was the work. Independence was the principle.
Over 60 years, the scope expanded beyond marine transport to include CMR surveys, technical heavy lift projects, warranty surveys, and towage approvals for offshore wind and oil projects from Polish yards - but the foundation stayed the same: educated personnel, international certifications, family ownership with no insurer or shipowner affiliations.
We answer to facts. That hasn't changed.
