Hormuz Shipping Tightens Again: Why Port Security Is Turning to Ground Robotics

Renewed tension around the Strait of Hormuz is redefining port security. The issue is no longer limited to naval escorts, radar surveillance and perimeter protection. It increasingly includes a more operational question: when human access to high-risk areas is restricted, who inspects terminals, tank farms and pipelines—and who moves sensors, spare parts and emergency supplies to the point of need?

As of July 13, the number of vessels transiting the Strait of Hormuz had fallen to six in a single day, the lowest level in five weeks. Data from ship-tracking firm Kpler showed no liquefied natural gas carriers entering the strait over the weekend, while many tankers crossing the high-risk waterway had switched off their automatic identification systems.

At the same time, conflicting statements over whether the strait remained fully open added another layer of uncertainty. For commercial shipping, the central question was no longer simply whether vessels could pass. It was whether risk could be predicted, whether insurance remained affordable and whether ports could continue operating without interruption.

This is pushing port security beyond conventional protective measures and turning it into an operational system involving mobile inspection, unmanned logistics, communications resilience and regional maintenance capacity.

From Maritime Risk to Port Security: Pressure Is Moving Ashore

The strategic importance of the Strait of Hormuz does not come only from its narrow geography. According to the United Nations Conference on Trade and Development, around 20 million barrels of oil passed through the strait each day in 2024, equivalent to roughly 25% of global seaborne oil trade. That included about 14 million barrels of crude oil and condensate and approximately 6 million barrels of refined petroleum products.

In the week before the latest disruption, around 38% of global seaborne crude oil trade, 29% of liquefied petroleum gas trade and 19% of liquefied natural gas trade moved through the same corridor. Asia is particularly exposed. Of the approximately 14.3 million barrels of crude oil shipped through Hormuz each day in 2024, 84% was destined for Asian markets. Around 83% of the 10.4 billion cubic feet per day of LNG moving through the strait also went to Asia.

Earlier this year, during one of the most severe periods of disruption, average daily vessel traffic reportedly fell by 97% from a normal level of around 129 ships. UNCTAD data also showed that between February 27 and March 9, oil prices rose by approximately 27%, while European gas prices increased by about 74%. These figures are usually cited in discussions about oil prices, freight rates and inflation. They also point to a less visible operational consequence: shipping pressure does not remain offshore.

A decline in tanker arrivals—or a sudden concentration of vessels waiting to berth—changes berth scheduling, storage-tank turnover, pipeline operations and vehicle movements inside the port. When ships deactivate identification systems, terminals lose confidence in arrival times and vessel status. When war-risk premiums increase, contractors may become less willing to send personnel into terminals, tank farms and offshore facilities.

Effective port security therefore cannot end at the waterline. It must also preserve the ability to inspect infrastructure and move equipment inside the port.

The Ground-Level Blind Spot in Port Security

Modern ports already deploy extensive networks of cameras, access-control systems, radar, drones and cybersecurity infrastructure. Yet high-risk environments still contain a significant ground-level blind spot.

A fixed camera may detect an abnormal condition, but it cannot carry a thermal imager behind a pipeline manifold. A drone can establish situational awareness quickly, but it is poorly suited to continuously transporting batteries, fire-suppression equipment, communications relays or repair tools. A fixed sensor can generate an alarm, but it cannot approach the source and verify the condition of a valve, gauge or damaged component.

Ground operations in ports and energy facilities can generally be divided into three categories. The first is repetitive inspection, including instrument reading, thermal-anomaly detection, gas-leak monitoring, vibration analysis and perimeter surveillance. The second is incident verification. Once a fixed sensor raises an alert, a mobile platform may need to approach the area and provide thermal imagery, high-resolution video, three-dimensional data or gas-detection readings. The third is continuous logistics. Even when personnel are restricted from entering an area, inspection equipment, spare parts, communications terminals, emergency power supplies and repair tools still need to reach the worksite.

Industry has already begun testing robots for such tasks. The Financial Times recently reported that one industrial-inspection robotics supplier had deployed 65 units in operational environments, primarily in Europe, and planned to expand into North America and the Middle East. The company estimated that the oil, gas and chemical sectors could eventually require as many as 100,000 inspection robots. That figure remains a supplier forecast rather than a confirmed order pipeline. However, the 65 operating units indicate that hazardous-environment inspection is moving beyond trade-show demonstrations and into limited commercial deployment.

On July 9, a Japanese energy company also announced a proof-of-concept programme using quadruped robots at a refinery. The trial focused on autonomous-driving stability, data-collection accuracy, anomaly-detection capability and practical operation in a real industrial environment. These projects do not suggest that ports will eliminate human inspectors. Their importance lies in transferring the most repetitive, hazardous and access-sensitive tasks to machines that can be remotely controlled or operate along predefined routes.

One Platform Cannot Perform Every Mission

The complexity of port environments means that port security is unlikely to be served effectively by a single type of robot. Main terminal roads, circular routes between storage tanks and external logistics corridors require speed, endurance and carrying capacity. Damaged surfaces, confined equipment areas, pipeline trenches, sand and loose gravel place greater value on low-speed traction, zero-radius manoeuvring and rough-ground mobility.

This is why wheeled and tracked platforms should be assigned different roles. REBIO GROUP’s product structure offers one possible two-tier ground-operations model: TerraMate platforms can perform main transport and wide-area inspection, while IronMule platforms can undertake close-in work near equipment and hazardous zones.

• TerraMate Main Transport: Connecting Controlled Areas with the Operational Edge

Public TerraMate product information lists a rated payload of 800 kilograms for the six-wheel UGV platform, a standard range of at least 110 kilometres and a maximum speed of 60 kilometres per hour. It also uses independent six-wheel drive and steering architecture and is rated to IP67.

In a port environment, these figures are not simply about speed or load capacity. They mean that one platform can transport multiple sensor packages, spare batteries, emergency communications equipment, toolboxes and mission modules between control centres, warehouses, berths, tank farms and pipeline nodes. TerraMate can also be configured with thermal imagers, gas-detection equipment, communications relays, lighting systems, robotic arms and other mission payloads.

Autonomous operation, however, must be integrated with perception sensors, computing systems, communications networks and site-specific safety procedures. It cannot be delivered by the vehicle chassis alone.

• IronMule Close-In Work: Completing the Final Ground Segment

The tracked IronMule UGV platform is better suited to areas where speed is less important and terrain is more broken or restricted. After a main transport platform delivers equipment to a secure transfer point, IronMule can carry or tow smaller mission modules into equipment-dense zones, temporary construction areas, gravel, soft ground or damaged access routes. It can then support close-range inspection, material towing and sensor placement.

This division creates a continuous mission chain rather than merely placing a large vehicle and a small vehicle in the same project:

TerraMate provides range and carrying capacity. IronMule provides access and terrain adaptability.

For port operators, this may be more practical than requiring one expensive general-purpose robot to combine high-speed movement, heavy transport, confined-space manoeuvring and rough-terrain mobility. It may also make procurement, maintenance and spare-parts planning easier to manage.

Regional Service Centres Determine Whether Robots Can Truly Enter Port Operations

Vehicle specifications are usually the easiest part of a port security project to compare. What often determines long-term operational value, however, is not maximum speed but the number of hours required to restore a failed system. Ports and energy facilities are expected to operate throughout the year. High temperatures, salt spray, sand, humidity, continuous vibration and shift-based use accelerate component wear.

Even if a robot performs well during a demonstration, it cannot become part of critical infrastructure if a failed motor, controller, seal, track, tyre or sensor requires weeks of cross-border shipping before the system can return to service.

A regional service centre therefore needs at least four capabilities. First, it must stock critical spare parts and mission modules. Second, it must perform routine inspection, fault diagnosis and module replacement. Third, it must train local operators, maintenance personnel and systems integrators. Fourth, it must continually adjust routes, payloads and operating procedures to local port conditions.

REBIO’s publicly described cross-border KD support model includes factory and workshop planning, equipment configuration, personnel training, quality systems, spare-parts planning, local adaptation and lifecycle support. TerraMate wheeled platforms can be delivered either as complete vehicles or through local KD assembly, depending on project requirements.

For major ports, energy groups, systems integrators and defence groups in the Gulf, the value of this model extends beyond lower shipping costs. It can place vehicle, payload and autonomous-system maintenance capabilities closer to the operating environment. It can also allow regional partners to retain control over customer relationships, software systems, communications architecture and mission-payload integration.

Port Security Procurement Will Shift from Buying Equipment to Maintaining Availability

How the situation around the Strait of Hormuz develops will depend on diplomacy, military decisions, shipping conditions and energy markets. Taking a position on the parties involved does not help a port operator answer the practical questions of daily operations.

A more relevant test is whether a port can continue inspecting infrastructure, transporting supplies, confirming alarms and restoring critical equipment when the risk level rises suddenly, personnel access is restricted and vessel-arrival schedules become uncertain. This means that port security acceptance criteria also need to change.

In addition to speed, range and payload, operators should examine:

• Whether the robot can stop safely or return after a communications failure;

• Whether inspection data is complete, traceable and securely stored;

• Whether sensors and mission modules can be replaced quickly;

• Whether the vehicle can operate for extended periods in salt spray, sand, heat and standing water;

• How long local personnel need to repair common faults;

• Whether the project includes strict end-user, end-use, export-control and cybersecurity screening.

For projects involving ports, energy facilities and critical infrastructure, end-user screening is not an administrative addition. It is part of sustainable project delivery. Technology suppliers must also define clear responsibility boundaries between the vehicle platform, mission payloads, autonomous systems, communications infrastructure and data management.

Energy Security Increasingly Depends on What Can Move Safely on the Ground

The strait remains important. Ships remain important. Maritime surveillance and escort capabilities remain important. But the latest tension around Hormuz is also reminding the market that maritime risk eventually reaches port roads, berths, storage tanks, pipelines and maintenance workshops.

Energy security increasingly depends on what can move safely on the ground.

The next stage of port security may not be defined by the most visually impressive robot. It may be defined by an operational system that can remain available over time: wheeled platforms for main transport and wide-area inspection, tracked platforms for close-in work, mission payloads for sensing and intervention, and regional service centres for maintenance, training, spares and upgrades.

The combination of TerraMate and IronMule is intended to provide this structure, extending from main-route transport to the final segment of ground operations. For regional partners seeking to establish robotic port inspection, emergency logistics for energy facilities or broader critical-infrastructure automation, the most practical starting point may not be a large one-time vehicle purchase.

It may be a measurable pilot programme covering one inspection route, one logistics mission and one local maintenance process inside a real port environment. When high risk is no longer an exceptional event but a variable that energy corridors must manage continuously, ground robotics moves from optional equipment to operational capability.
