What Royal Dirkzwager does

Royal Dirkzwager B.V. is a Dutch maritime intelligence and software company founded in 1872 and headquartered in Maassluis, Netherlands, with additional offices in Rotterdam and Antwerp. The company operates a 24/7 fully redundant control room and serves more than 800 organisations across the maritime value chain, including ship agencies, marine suppliers, terminal operators, oil & gas operators, offshore wind farm operators, and shipping companies. Its core platform, Ship2Port, is a web-based SaaS system that aggregates satellite-based AIS data on over 200,000 vessels globally, integrates with port community systems in Rotterdam, Amsterdam, and Antwerp, and delivers real-time vessel tracking, validated ETA/ETB predictions, fleet monitoring, ISPS visitor registration, port call reporting, and business intelligence. The platform processes over 500,000 terminal visits annually and supports a free trial onboarding flow in addition to enterprise subscriptions.

The company's product portfolio extends well beyond Ship2Port. ROAM (Remote Offshore Asset Monitoring) provides 24/7 vessel traffic monitoring for offshore oil & gas platforms, wind farms, subsea cables, and emerging offshore infrastructure (CCS, floating wind, floating solar), using AIS, radar, and CCTV with VHF operator intervention. Regulatory compliance offerings include ISPS access control (notably Europe's first fully unmanned ISPS system launched at Nobel in October 2025) and the Ship Security Alert System (SSAS) for covert piracy and emergency alerting. Additional revenue streams include ship agency reporting services, 24/7 maritime call centre support, the PortCalculator tool for port fee estimation, and AI-powered business intelligence built on Power BI. The recent acquisition of Routescanner from the Port of Rotterdam Authority (May 2026) extends the platform into multimodal hinterland transport planning, integrating vessel movements with inland waterway, rail, and road options.

Royal Dirkzwager generates revenue through a combination of SaaS subscriptions (Ship2Port with freemium trial conversion), managed services for VTMs and SSAS, enterprise contracts for ship agency and BI consulting, and professional services for call centre support. Go-to-market is hybrid: a self-serve PLG motion for Ship2Port alongside consultative direct sales for enterprise VTMs, SSAS, and BI engagements. The company is privately held, owned by CEO Joan Blaas since 2022, and operates with a 11-50 employee headcount.

Direct peers

• FleetMon: AIS vessel tracking and maritime data service providing ship positions, port calls and vessel particulars to commercial shipping users. Directly competes with Ship2Port's tracking and port-call reporting functionality for ship agencies, ports and marine suppliers.
• VesselFinder: AIS-based vessel tracking platform with global vessel positions, port calls and voyage predictions. Overlaps directly with Ship2Port's real-time AIS visibility and ISPS/fleet tracking use cases for ports and maritime service providers.
• MarineTraffic: Global AIS-based vessel tracking and maritime intelligence platform offering real-time ship positions, port arrivals, and voyage data. Closest direct competitor to Royal Dirkzwager's Ship2Port tracking layer, with similar B2B/B2C SaaS model and global vessel coverage.
• Spire Maritime: Satellite-AIS and maritime analytics provider offering global vessel tracking, weather routing and commodity-flow data. Competes with Ship2Port on AIS quality/coverage and with Royal Dirkzwager's BI services on historical voyage analytics.
• Pole Star Global: Provider of ship tracking, sanctions compliance (OFAC/UK/EU) and vessel risk intelligence used by shipping companies, banks and compliance teams. Comparable to Royal Dirkzwager on the maritime data layer and adjacent on regulated-compliance positioning.

Broad incumbents

• Kpler: Global maritime and commodity intelligence platform covering vessel tracking, trade flows, shipping, and energy markets. A broader incumbent with deeper analytics and enterprise scale that overlaps Royal Dirkzwager's BI and AIS-based tracking on the data-monetisation layer.
• Lloyd's List Intelligence: Long-established maritime intelligence provider offering vessel movements, ownership, sanctions and shipping news to global commercial and government customers. Overlaps with Royal Dirkzwager on vessel movements and business intelligence but operates at broader scale and global scope.
• Clarkson Research: Shipping intelligence and research arm of Clarkson PLC covering ship movements, fleet data, market analysis and offshore. Comparable to Royal Dirkzwager's BI services on the historical-data and competitive-positioning analytics side, but with much wider market coverage.

Emerging players

• Dataloy: Maritime operations and voyage management platform for charterers, operators and ship agencies. Overlaps with Ship2Port on port-call planning and ship-agency workflows but focuses on commercial voyage operations rather than AIS tracking and offshore monitoring.

Others

• Vissim: Provider of advanced vessel traffic monitoring (VTM) software used in ports and offshore. Royal Dirkzwager is a Vissim Gold Partner and integrates Vissim technology into its ROAM service, making it both a core enabler and a potential competitive channel for VTM deployments.
