MCC Shelter Fire Protection & Safety Monitoring Systems — A Reliable Shield for Critical Electrical Equipment

In oil & gas, chemical, power, and offshore projects, MCC (Motor Control Center) shelters play a crucial role in controlling and protecting core electrical systems. The safety of MCC shelters directly affects the stability and reliability of the entire project.

TLS designs MCC shelters with advanced structural integrity, protection, and fire safety systems, customizable according to client safety requirements, ensuring a stable and controlled environment for critical electrical equipment.

1. Core Protection Concept: A Safe Space for Critical Systems

MCC equipment is typically non-explosion-proof and sensitive to environmental conditions such as temperature, humidity, gas composition, and air cleanliness. TLS MCC shelters provide:

• Enhanced airtight structure – reduces dust and moisture ingress, extending the life of electrical equipment.
• Positive-pressure system (optional) – maintains internal pressure higher than the environment, preventing combustible gas entry, suitable for Zone 1/Zone 2 areas.
• Corrosion-resistant structure with thermal insulation – ideal for offshore platforms, chemical plants, or high-humidity environments.

2. Professional Fire Protection Systems

Given the high density of electrical equipment and fire risk, TLS offers customizable automatic fire protection systems:

• Fire detectors (smoke/heat sensors) – real-time monitoring of fire hazards.
• Automatic extinguishing devices – rapidly respond in early-stage fires to minimize electrical damage.
• Integrated alarm systems – trigger audible and visual alerts and can interlock with emergency shutdown systems if required.

​All fire protection solutions can be customized to comply with IEC standards and offshore platform safety regulations, ensuring the required safety level on-site.

3. Safety Monitoring Systems: Reliable and Scalable

TLS MCC shelters can be equipped with multiple safety monitoring functions to maintain a stable internal environment and protect equipment life:

• Gas detection – monitors combustible or toxic gases, ideal for oil & gas facilities.
• Temperature and humidity monitoring – prevents overheating or moisture damage.
• Pressure monitoring (for positive-pressure MCC shelters) – ensures consistent internal pressure.
• Alarm system – provides on-site audio-visual warnings to reduce risk.

4. Future-Ready Upgrade Capability

The system design reserves data interfaces for potential future upgrades, including:

• Remote monitoring capability
• Integration with data logging systems
• Digital platform interfaces (SCADA or DCS)

Note: This does not imply that the current system includes remote operation functionality, but it enables clients to expand in the future.

5. Modular Design for Various Applications

MCC shelters are modular, allowing customization for multiple use cases:

• Medium- and low-voltage switchgear
• Motor Control Centers (MCC/PLC/VFD/VSD)
• Remote operation and monitoring cabinets
• Offshore platform production control units
• Electrical control and protection stations in chemical plants

All structures can be tailored to equipment size, cable entry, cooling requirements, and site layout.

6. Delivery & Service: Reliable Support Throughout the Lifecycle
​

• Designed to comply with DNV 2.7-1 / IEC 60079-13 standards (as required)
• Configurable for Zone 1 / Zone 2 safety levels
• Factory pre-assembled and tested for turnkey delivery
• Global transport, installation guidance, and after-sales support

TLS engineering teams provide complete design documentation, interface diagrams, lifting plans, and wiring layouts, ensuring MCC rooms can be rapidly deployed on-site.
