Introduction: Smart Air Quality for L&T PES Visakhapatnam
L&T Precision Engineering & Systems (PES) is a key division of Larsen & Toubro focused on developing indigenous, high-performance platforms for land and sea applications. At their Visakhapatnam dockyard, a critical manufacturing hub, the team handles a wide range of precision processes, including full-metal finishing, custom fabrication, and system integration activities that inherently generate particulate emissions and are sensitive to local climate conditions.
Being located in a coastal zone, the facility faces constantly high humidity, variable wind patterns, and intense industrial activity, all of which create a complex air quality environment. These factors can impact not just compliance with environmental regulations but also affect the quality and reliability of engineering processes. To address these challenges, L&T PES required a monitoring solution that provided accurate, real-time environmental data, seamless integration with their existing SCADA system, and the flexibility to automate responses, such as dust suppression.
Challenges: Tackling Coastal Conditions and Process Complexity
As a precision engineering hub for systems used across land and sea, L&T PES operates under strict process requirements. The dynamic nature of dockyard activities brought forward several environment-linked challenges:
- High Humidity and Coastal Conditions: The dockyard’s proximity to the sea means consistently high humidity, which was affecting process efficiency and material integrity.
- Need for Real-Time Emission Tracking: Pinpointing specific sources of pollutants like PM2.5, PM10, CO, CO2, SO2, NO2, NH3, and O3 along with temperature and humidity, was difficult without continuous, localized data.
- Emission Source Identification: With various operations happening simultaneously, pinpointing exact emission contributors became difficult without real-time data.
- Integration Needs with SCADA Systems: L&T PES needed a solution that could be directly integrated into their in-house SCADA system via Ethernet for seamless control and monitoring.
- Manual Triggering of Dust Suppression: Their dust suppression relied on periodic checks and manual activation, which was inefficient and resource-intensive.
These challenges required a smart, rugged, and integration-ready monitoring solution that could deliver actionable data in real-time.
Solution: Polludrone with Smart Integration and Automation
L&T PES chose Oizom’s Polludrone, a compact, industrial-grade ambient air quality monitor, installed on 20th December 2024. The decision was influenced by several critical advantages:
- Advanced E-breathing Technology: Ensures consistent and accurate sampling even in fluctuating dockyard conditions.
- Multi-Parameter Monitoring: Polludrone tracks PM1, PM2.5, PM10, CO, CO2, SO2, NO2, NH3, O3, along with temperature and humidity, giving L&T a full view of environmental variables.
- Direct SCADA Integration via Ethernet: Polludrone’s easy-to-install feature allowed seamless integration with L&T’s existing SCADA infrastructure without external loggers.
- Relay-Based Automation Capabilities: The device’s relay output was linked with dust suppression systems, automating activation based on real-time PM thresholds.
- Envizom Software for Smart Monitoring: With modules like Alerts, Automation, and Analytics, Envizom allows for threshold-based notifications, historical data analysis, and custom automation triggers.
This tailored deployment allowed L&T to monitor, automate, and optimize processes based on live air quality data.
Transformation: Smarter Processes, Cleaner Outcomes
Post-installation, L&T PES saw immediate improvements in its operational efficiency and environmental control.
- Pinpointing Emission Sources: Real-time pollutant data helped the team identify and control emission hotspots across the dockyard.
- Automated Dust Suppression: Polludrone’s integration with suppression systems eliminated manual oversight, ensuring proactive dust control.
- Process Scheduling: Insights from temperature and humidity data allowed L&T PES to optimize when and how specific processes were initiated.
- Impact Assessment of Humidity: Continuous monitoring helped the team study how high humidity levels affected certain operations, enabling them to introduce preventive measures.
- Data-Driven Sustainability: Access to continuous data and trend analysis supported better decision-making and demonstrated compliance with environmental norms.
L&T PES has successfully turned environmental monitoring into a strategic tool, using Oizom’s system to drive both compliance and operational improvement.
Broader Impact: Enabling Data-Led Environmental Strategy
The integration of Oizom’s Polludrone at L&T Precision Engineering & Systems goes beyond operational improvement. It represents a shift towards long-term environmental accountability and smarter industrial practices.
- Strengthening ESG Initiatives: The availability of air quality insights supports L&T PES in aligning with Environmental, Social, and Governance (ESG) goals, which are increasingly valued by global stakeholders and clients.
- Cross-Team Collaboration: With the help of Envizom’s centralized dashboard and modules, various departments can now collaborate better, using unified environmental data to inform decisions.
- Support for Regulatory and Audit Readiness: With continuous monitoring, automated reporting, and data backup, L&T PES is always ready for internal reviews, environmental audits, and compliance reporting.
Conclusion: Precision Meets Sustainability
L&T Precision Engineering & Systems’ collaboration with Oizom shows how industrial precision and environmental responsibility can go hand-in-hand. By choosing Polludrone, L&T PES has moved from manual, reactive processes to automated, data-driven operations that are safer, more efficient, and environmentally sound.
With real-time monitoring, smart automation, and SCADA integration, they’ve not only gained control over their dockyard emissions but have also taken a measurable step towards sustainable manufacturing. This partnership reflects the growing trend of industries using technology not just to comply, but to lead.
