The Hague is the administrative capital of the Netherlands — seat of the government, parliament, royal court and the International Court of Justice. From an industrial integration perspective, however, it isn't Zuid-Holland's main draw — that's the Rotterdam port and petrochemical complex 25 km north, the largest in the European Union and one of the largest in the world.
Rotterdam petrochemical complex
Port of Rotterdam is Europe's largest port by annual cargo throughput (about 440 million tonnes) and the world's fourth-largest. Across the port area from Maasvlakte through Botlek and Europoort to Pernis, a petrochemical complex is concentrated that processes oil products for the entire Western European market. Shell Pernis is Europe's largest refinery (capacity about 400,000 barrels a day), ExxonMobil Botlek is the second-largest player, BP Refining Rotterdam the third.
For an integrator it's a world where every technical conversation begins with "which zone are you working in?" — ATEX zone 0 (continuous presence of explosive atmosphere, e.g., inside tanks), zone 1 (occasional presence, e.g., around pipe joints), zone 2 (rare presence, e.g., warehouses). Intrinsically safe equipment with EPL Gb or Db classification by atmosphere. Every PLC firmware update goes through SIL-3 hazard analysis under IEC 61511. Every certified technician has training under NEN-EN-IEC 60079 (European ATEX harmonisation).
Honestly: the petrochemical core in Rotterdam is primarily for long-standing Dutch suppliers — Stork, Bilfinger Tebodin, Mammoet, Sweco — with decades of presence in zones 0/1 and a verifiable history for Shell, ExxonMobil, BP. For an integrator from the V4 space it's a realistic scenario in the periphery: administrative IT infrastructure (office complexes at Maasvlakte Plaza), maintenance outside active ATEX zones, support for zone projects in subcontractor mode for a Dutch tier-1 general.
The Hague as administrative centre
Government ministries (Ministerie van BZK, Ministerie van Defensie, Ministerie van EZK) have their own supplier chains via TenderNed, which without pre-qualification are inaccessible to a Slovak supplier. For these contracts entry is via consortium with a Dutch general, not direct tendering. This isn't impossible, but it's a long road via Rijksdienst voor Ondernemend Nederland (RVO) and EU SUM ECP processes — currently outside our tender calendar.
European institutions — Europol HQ, Eurojust HQ, ICC (International Criminal Court), ICJ (International Court of Justice) — have their own IT environment with strict security classification. For an integrator without pre-qualification and without NATO Secret clearance, this is a closed orbit.
Holland Industrial Cluster and Westland
Outside The Hague and Rotterdam, Zuid-Holland is also home to Europe's largest greenhouse cluster — Westland, where tomatoes, peppers and flowers are grown in industrialised greenhouses with fully automated climate, hydroponics and LED lighting. For an integrator we open potential via industrial LED lighting (DALI-2 or Casambi protocol), climate control (Priva, Hoogendoorn), and integration of greenhouse management via ISA-95-compatible MES layers.
This segment is realistically more accessible than the petrochemical core — the Westland greenhouse sector also has smaller tier-2 and tier-3 suppliers, where entry via technology specialisation (LED retrofit, Loxone or KNX integration for smaller greenhouses) is realistic.
Our commuting relationship
The Hague is from AMS Schiphol about 45 minutes by direct train (Intercity), or 50 minutes by car. For most contracts we work by air via AMS Schiphol, with accommodation in The Hague or in the Rotterdam satellite zone (Vlaardingen, Schiedam).
From Prešov by air via AMS (about 2.5 h) plus 1 hour transport to The Hague. For longer projects team rotation in two-week cycles.
Which pillars fit best
For the Rotterdam petrochemicals — **Electro + Automation** with strong ATEX and SIL focus, but only in peripheral mode (administrative IT, maintenance outside active ATEX zones). We leave core ATEX zones 0/1 to Dutch tier-1 suppliers.
For the Westland greenhouse cluster — **Automation + Smart Buildings**. DALI-2 LED control, KNX / Loxone integration, Priva or Hoogendoorn climate control, MES supervision via Ignition or other OPC UA broker.
For administrative complexes in The Hague — **Electro + Software/AI**. Structured cabling, AV installations, smart-building control via Schneider EcoStruxure or Siemens Desigo.
What you shouldn't yet ask us about in The Hague
Government core IT systems — require TenderNed pre-qualification and often NATO Secret clearance.
Petrochemical core in zones 0/1 — primarily for Dutch tier-1 firms with decades of ATEX history.
European institutions (ICC, ICJ, Europol) — closed orbit with their own classified suppliers.
