Service Overview

Leak Detection & Repair

OGI and Method 21 fugitive emission surveys that detect, quantify and track repair of industrial leaks. Green Vertex delivers this service to industrial, commercial and governmental clients across Saudi Arabia and the GCC, applying internationally recognized methodologies within our ISO-certified quality management system.

Our specialists work closely with your team from initial scoping through final reporting, ensuring the program is tailored to your facility's specific regulatory obligations, operational constraints and risk profile — turning fugitive emission data into a clear, actionable repair program.

Fugitive emissions from valves, flanges, connectors and other components are among the largest sources of uncontrolled loss at industrial facilities, and they often go unnoticed without a structured monitoring program. Our LDAR teams combine calibrated OGI and Method 21 instrumentation with a disciplined tagging, screening and repair-verification workflow, so every component in your inventory is accounted for and every leak is tracked from first detection through confirmed repair. The result is a defensible record that supports both regulatory compliance and real operational savings from reduced product loss.

Our Offering

What We Offer for LDAR Services

Leak Detection Surveys

OGI and Method 21 screening of every tagged component across the facility to locate fugitive emissions early. Surveys are scheduled to match your regulatory monitoring frequency, and each pass is logged against the facility's component inventory so nothing is missed between cycles.

Component Monitoring

Ongoing monitoring of tagged valves, flanges, connectors and other components against the facility's leak inventory and history. We track condition trends over time, flagging components that show early signs of degradation before they become active leaks.

Repair Verification

Re-screening of repaired components to confirm leaks have been eliminated within program timelines. Verification results are logged against the original repair tag, giving you a closed-loop record from detection through confirmed resolution.

Emission Inventory

Quantification of fugitive emissions across all monitored components to support regulatory reporting and inventory management. Data is structured to feed directly into facility-wide emission inventories and annual compliance submissions.

LDAR Program Development

Design of facility-specific LDAR programs, procedures and monitoring plans from the ground up. We define component tagging conventions, monitoring frequencies, repair timelines and QA/QC procedures aligned to your regulatory obligations.

Compliance Reporting

Preparation of regulator-ready reports summarizing survey results, repair status and emission totals. Reports are structured to stand up to audit, with full traceability back to raw field data and instrument calibration records.

FAQ

Frequently Asked Questions

Leak Detection and Repair (LDAR) is delivered by Green Vertex's specialist team using internationally recognized methodologies. OGI and Method 21 fugitive emission surveys detect, quantify and track repair of industrial leaks. The scope is tailored to your facility, project type and applicable regulatory requirements in Saudi Arabia and the wider GCC.

Timelines depend on facility size, component count and complexity. Straightforward assessments can be completed within a few days of mobilization, while larger or multi-site LDAR programs may run over several weeks. We confirm a firm schedule during project scoping.

Many facilities and projects in the Kingdom are required to demonstrate compliance through activities such as leak detection and repair under Saudi EPA / NCEC requirements or sector-specific regulations. Our team can confirm the specific obligations that apply to your operation.

Green Vertex combines ISO-certified quality management, experienced specialists and modern instrumentation to deliver LDAR programs that are accurate, defensible and delivered on schedule — backed by responsive client support throughout the project.
