N-Sea Group Tech Stack

Offshore subsea services fleet for energy infrastructure projects

Oil and Gas Dordrecht, Zuid-Holland 201–500 employees Founded 1932 Privately Held

N-Sea operates a 14-vessel subsea services fleet serving offshore energy projects across survey, cable installation, UXO clearance, and decommissioning. The tech stack — AutoCAD, ArcGIS, QGIS, Python, SQL, Oracle Primavera — reflects heavy reliance on CAD/geospatial design and project management rather than modern cloud or automation tooling. Engineering-heavy hiring (13 roles) against steady velocity signals growth in core project delivery; the absence of any adopting/replacing signals suggests a mature, operations-driven org with limited digital transformation underway.
