Security Robots Chemical Park: Perimeter, Tank Farm and KRITIS Obligation

A chemical park is not an office building with a fence. It is a linear protected site with tank farm, pipeline corridors, pipe bridges, plant gate and visitor parking, often spread across 5 to 25 kilometres of perimeter. Anyone trying to secure that perimeter with classical Wachschutz alone fails on the labour market and on the arithmetic of shift rosters.

Security Robots Chemical Park: Why the Standard Guard Post Falls Short

The standard guard post at the plant gate secures the plant gate. It does not secure the 12 kilometres of fence line, the 800 metres of pipeline corridor behind the tank farm, nor the pipe bridge to the neighbouring plant. A 24/7 post costs between 15,000 and 25,000 euros per month depending on tariff region and qualification. [source required] Geometrically it covers not a single square metre of fence line.

The BDSW documents structural staff shortages in the German security industry with more than 10,000 permanently unfilled positions. Anyone tendering for plant security personnel in sufficient number and quality in 2025 will not get it. The gap cannot be closed by wage increases alone.

Security robots in a chemical park close the distance between static post and CCTV control room. They patrol at night on fixed routes, deliver thermal imaging, document waypoints and alert the control room. From 2026 onwards, the question will no longer be whether this is sensible, but whether it is demonstrably implemented: the KRITIS chemical sector must document structural and technical protection measures at the perimeter.

Next step: KRITIS sectors overview.

ATEX, Ex Zones and the Correct Deployment Area

The most important boundary first, because no Ex protection officer will continue the conversation without it: QR-2 and QR-3 patrol outside Ex zones 0, 1 and 2. Full stop. Inside classified Ex areas, human specialist personnel with approved equipment remain mandatory. The robot takes the surrounding area: paved plant roads, perimeter paths, visitor parking, tank farm ring outside the containment.

Tank farm surveillance is performed at a distance of 5 to 15 metres from the safety containment. Thermal camera and visual sensors detect temperature anomalies on the tank shell, unauthorised persons in the restricted area and mechanical tampering with valves. A gas leak indication from distance does not replace a calibrated Ex sensor in the zone. It delivers an early indicator for the control room.

Pipeline corridors and pipe bridges can be checked efficiently at night via thermal signature. Tampering, unauthorised approach and heat development are visible in the IR image within minutes.

Legally, the EU Machinery Regulation 2023/1230 applies to the platform itself, EN ISO 13482 is used as the reference standard for autonomous mobile platforms. The Ex classification of the deployment area remains the responsibility of the operator and their Ex protection officer.

Next step: Perimeter protection in industrial parks.

The Three Critical Patrol Scenarios in a Chemical Park

Three scenarios pay off in nearly every chemical park.

Plant gate and visitor parking. At night the robot identifies unauthorised vehicles, captures licence plates and controls the outdoor area without continuous post staffing. The Wachschutz concentrates on shift changes and visitor management during the day.

Tank farm ring. Thermal anomaly detection on tank shells, person detection in the restricted area, drone detection above the storage areas. The robot drives a fixed ring with defined waypoints, response to anomaly occurs via route deviation and alarm to the control room.

Pipeline and pipe bridge corridor. Patrol along linear infrastructure over 2 to 8 kilometres with fixed waypoints. The route can hardly be covered economically by human patrols, because a patrol vehicle needs 30 to 45 minutes per pass [source required] and at night carries noise into the neighbourhood.

The low-noise night patrol reduces complaints from adjacent residential areas compared to patrol runs with a Wachschutz vehicle. Alerting to the plant's own control room occurs within 8 seconds of detection [source required], including geocoordinate and live stream.

Next step: QR-3 with LiDAR and drone detection.

KRITIS-Dachgesetz: Obligations for Chemical Park Operators

The KRITIS Umbrella Act draft, Bundestag-Drucksache 20/9262, names the chemical sector as a critical facility from defined volume thresholds. The KritisV sets the sector-specific thresholds. Anyone above them is an operator of critical facilities within the meaning of the law.

This results in three documentation-mandatory components:

1. All-hazards risk analysis covering natural hazards, sabotage, espionage, cyber.
2. Protection concept with structural and technical measures.
3. Registration with the BBK as operator of a critical facility. [link deadline and legal basis]

Structural and technical protection measures at the perimeter are not optional. They form part of the resilience obligations. Security robots can be documented as a technical measure for detection and delay of intrusion attempts, provided that patrol routes, sensors, alarm paths and escalation routes are described in the protection concept.

NIS-2, Directive 2022/2555, supplements the physical obligation with cyber resilience and board liability. Both strands must come together in the protection concept. A robot that transmits via mobile network is a networked component. It therefore belongs in the NIS-2 assessment.

Next step: KRITIS-Dachgesetz checklist 2026.

Drone Detection: The Underestimated Risk Above the Tank Farm

Industrial espionage and sabotage reconnaissance by drone have been documented in chemical parks since 2022. Incidents range from commercial multicopters over tank farm areas to repeated nocturnal overflights with thermal imaging camera.

QR-3 detects drones via RF signatures and acoustic patterns within a radius of up to 800 metres. [source required] Detection triggers alerting of the control room, documentation of the signature and securing the incident for reporting to Bundespolizei and BSI. Active defence (jamming or taking over a drone) remains reserved for state authorities. The operator delivers detection and forensics, nothing more.

The combination of ground patrol plus airspace detection is effectively standard for KRITIS chemical operators from 2026 onwards, because the protection concept remains incomplete without an airspace component. Anyone documenting a tank farm without addressing drone detection will be required to rework it during the audit interview.

Next step: NIS-2 and board liability.

TCO: Guard Post Versus Security Robot Chemical Park

The calculation the board wants to see is sober.

Classical model. Three 24/7 guard posts at plant gate, tank farm and pipeline cost between 45,000 and 75,000 euros per month in pure personnel cost, depending on tariff region, qualification and surcharges. [source required] Sickness absence, holiday and shift overlap are included.

Hybrid model. The same geometric coverage with two QR-2 and one QR-3 costs 10,800 euros per month as pure OpEx. [source required] No CapEx, no balance sheet activation, no depreciation in the plant budget.

Robotics-as-a-Service includes hardware, software updates, maintenance and replacement on defect. Contract duration is 24 months, delivery occurs within 48 hours of pilot approval. Personnel are not replaced, they are transferred into qualified intervention teams: six static posts become two intervention teams plus three robots. The wage cost per head of intervention teams is higher, total cost falls.

This calculation withstands any CFO review when intervention times and KRITIS proof documentation are attached.

Next step: TCO comparison guard service versus robot.

Hybrid Model: Human, Robot and Control Room

The role split is not negotiable. Robot detects and documents. Human intervenes and decides. Anyone softening this line builds a system that will not stand before the auditor. Nor before the works council.

The control room receives the robot's live stream, the thermal image and the alarm protocol in parallel to the existing CCTV matrix. The operator interface integrates with existing PSIM systems via open interfaces. A separate second control room is not required.

Through precise geolocation, intervention time falls below 4 minutes in typical chemical park topologies. The post knows where the incident occurred, which thermal signature is present and whether a person is visible.

Shift rosters ease. Two intervention teams with qualified §34a Sachkundeprüfungen plus three robots replace six static posts without loss of protection. Works council involvement happens early and transparently. The story towards the workforce is upgrade: fewer night posts at the cold gate, more qualified day shift with intervention responsibility. That is the only narrative that holds at the plant.

Next step: Robotics-as-a-Service without CapEx.

Pilot: 14-Day Blueprint for Chemical Park Operators

A pilot that works follows a simple sequence.

Week 1. Perimeter survey with GPS, definition of waypoints. Coordination with plant fire brigade and Ex protection officer to delimit patrol areas against Ex zones. Definition of escalation paths with the control room. Written release of routes by the Ex protection officer.

Week 2. Installation of charging infrastructure at two or three points along the perimeter. Connection to the control room via VPN. Trial patrol with Wachschutz escort over three nights. Adjustment of waypoints and sensor thresholds.

Weeks 3 and 4. Full operation with weekly report. Threshold calibration for thermal anomalies, drone detection and person detection. Escalation paths are sharpened based on real incidents, not on assumptions. Proof documentation for the KRITIS protection concept emerges in parallel: patrol logs, alarm statistics, control room response times.

At the end of the fourth week, board and auditor receive a pilot report. The decision on the full contract is made on the basis of this report, not on the basis of a demo video.

Anyone operating the chemical park today and required to deliver KRITIS proof in 2026 has twelve months. Pilot in Q2, full contract in Q3, audit readiness in Q4 is the realistic sequence. The alternative is rework under time pressure in the audit interview. That is more expensive than any patrol.

Concrete next step for plant management: review the specification of QR-3 with LiDAR and drone detection and schedule a 14-day pilot.
