What Periplus Group does
Periplus Group BV is a privately held Dutch subsea data services and software company headquartered in Amsterdam, operating through subsidiaries Periplus Consultancy, Periplus Resources, Periplus Archeomare, and the newly formed Periplus Solutions (2024). The company delivers hydrographic and geophysical data processing, maritime archaeological studies, on-site offshore staffing (hydrographic surveyors, client representatives, dive supervisors), and a cloud-based subsea data management platform called GRIDit (launched in its cloud form in 2022, with the GRIDit ALIGN module added in 2024). GRIDit stores and visualizes data on subsea assets including wind turbine foundations, cables, pipelines, scour protection, and seabed conditions, and is complemented by SonarReg, a sonar observation registry built for Rijkswaterstaat. The company sells primarily through direct enterprise and government field sales to offshore wind developers, oil & gas operators, CCS projects, hydrographic survey firms, and maritime authorities, with a customer base that includes Rijkswaterstaat, EnBW, Dana Petroleum, Norther, Gemini, Petrobras, Wintershall, Porthos, Otary, the Flemish Government, and RVO. The business model combines multi-year professional services and staffing contracts with a subscription-based SaaS component for GRIDit, supported by ~25 in-house staff and an extended network of freelancers, and is differentiated by deep domain specialization across hydrography, GIS, maritime archaeology, and full-stack software engineering, evidenced by ISO 9001/27001/45001 and SIKB 4000 certifications.

Periplus Group competitors and assessment
Company assessmentDirect peers
- Fugro: Dutch-headquartered global leader in geo-intelligence, hydrographic surveys, and offshore site characterization. Direct overlap with Periplus on offshore wind and oil & gas site characterization across NW Europe, although Fugro operates at a far larger scale across geographies and asset classes.
- Reach Subsea: Norwegian subsea services provider offering hydrographic surveys, ROV operations, and offshore support for oil & gas and offshore wind. Competes with Periplus in the same North Sea basins for survey and inspection work.
- N-Sea: Dutch subsea cable, pipeline, and IRM survey and inspection provider. Directly overlaps with Periplus on subsea cable survey and asset integrity services, including the offshore wind segment GRIDit supports.
- DEEP BV: Dutch hydrographic and geophysical survey company delivering UXO, magnetometer and offshore wind site characterization. Listed as a Periplus cooperation partner but operates in directly overlapping service lines.
- M2 Subsea: UK-headquartered subsea services company delivering survey, intervention and inspection across offshore wind and oil & gas. Comparable in scope to Periplus' subsea data acquisition and offshore project execution offering.
- GEO Plus: Dutch UXO and geophysical survey provider. Listed as a Periplus partner that supplied hydrographic surveyors for UXO surveys; competes for UXO risk-analysis work tied to offshore wind, CCS and dredging projects.
- EXAIL: Provider of subsea navigation, positioning and survey instrumentation (INS, USBL, LBL, sonar) including the iXblue and Klein ranges. Comparable to Periplus in serving hydrographic survey workflows, with a more equipment-centric offering.
- EIVA: Danish hydrographic survey software vendor (NaviSuite) for subsea data acquisition, processing and visualization. Competes with GRIDit for survey-data management and chart production workflows on offshore wind and infrastructure projects.
Broad incumbents
- Kongsberg Maritime: Norwegian incumbent providing subsea sensors, hydroacoustic equipment and integrated offshore technology. Sells into the same survey ecosystem and competes with Periplus' partners at the instruments, software and integrated-system layer.
Emerging players
- Terradepth: US-based autonomous ocean data and subsea survey-as-a-service company. Emerging software-first peer to GRIDit, applying SaaS and autonomous vessels to ocean data acquisition and management for offshore operators.
