Who We Are

Offstream is a global Asset Integrity Services provider based in India dedicated to ensuring that critical industrial assets operate safely, reliably, and cost-effectively throughout their lifecycle. Established by experienced inspection, integrity, and maintenance professionals, we support oil & gas, petrochemical, chemical, fertilizer, and port industries across India, the Middle East, Europe, and the United States.

Our strength lies in combining engineering expertise, field experience, and internationally recognized standards to help asset owners manage risk, optimize inspection strategies, and extend asset life. We apply structured, data-driven methodologies to support informed decision-making and compliance while minimizing downtime and operational risk.

What We Do

Offstream delivers integrated Asset Integrity and Reliability solutions, covering static equipment, pipelines, structures, and rotating machinery.

• Risk-Based Inspection (RBI) : We develop API 580/581–based RBI studies by integrating process data, corrosion circuits, inspection history, and consequence modeling. Our RBI programs optimize inspection intervals, prioritize high-risk equipment, and support ALARP-aligned inspection planning.

• Asset & Structural Integrity Management (AIMS / SIMS) : Our AIMS and SIMS frameworks, developed in line with ISO and API standards, ensure assets remain fit-for-purpose throughout their operating life. We integrate inspection data, anomaly assessment, and integrity dashboards to maintain structural and asset reliability.

• Reliability-Centred Maintenance (RCM) : Offstream applies FMEA and functional failure analysis to develop reliability-centred maintenance strategies for rotating and static equipment. Our RCM solutions balance safety, reliability, and lifecycle cost while improving equipment availability.

• Pipeline Integrity Management : We provide end-to-end pipeline integrity management, incorporating ICDA, ECDA, in-line inspection data, defect assessment, corrosion evaluation, and risk ranking to prevent failures and ensure regulatory compliance.

• Fitness-for-Service (FFS) & Remaining Life Analysis (RLA) : Our API 579 / ASME FFS assessments evaluate equipment with corrosion, cracking, or mechanical damage. We perform Level 1–3 assessments, stress analysis, and remaining life calculations to support safe operation and repair decisions.

• Materials Selection and Corrosion Modelling : Offstream delivers material selection studies, corrosion risk assessments, root cause analysis, and failure investigations, supported by corrosion modeling and damage mechanism reviews in accordance with NACE, API, and ASME standards.

• Shutdown & Turnaround Services : We support shutdowns through inspection planning, execution, data capture, and post-shutdown integrity assessment—minimizing downtime while maintaining safety and inspection quality.
