Commissioning as a Service (CaaS): De-risking Complex Industrial Infrastructure

Q: What is Commissioning as a Service (CaaS)?

Commissioning as a Service (CaaS) is Navsar's engineering-led approach to project commissioning. Unlike traditional commissioning which is often reactive, CaaS integrates early into the project lifecycle to define boundaries, systemise logic, and ensure a predictable, auditable handover through our Completions Management System.

Q: What does Engineering stand for in your services?

Engineering Services form the core of our operations. Navsar provides engineering leadership and completions authority — directing, verifying and taking technical control of the works to deliver a first-time-right startup and an audit-ready handover. We own the engineering outcome; we do not supply manpower or act as a staffing agency.

Q: Which geographic regions does Navsar cover?

Navsar has a global footprint with significant project experience across 25+ countries across 4 continents. Our teams are mobile and equipped to support critical infrastructure projects in both established and emerging markets worldwide.

Q: What industries do you specialise in?

We specialise in high-stakes critical infrastructure, including Power Generation (Thermal, Renewable, Nuclear), Oil & Gas (Offshore FPSO, Onshore Refineries), Hyperscale Data Centres, Metro Rail systems, and EV Charging infrastructure.

Q: How does Navsar de-risk critical infrastructure projects?

We de-risk projects through technical precision and early intervention. This includes rigorous design reviews, interface management between siloed vendors, standardised test procedures, and our 'Commissioning Assurance Audit' which identifies potential single points of failure before startup.

APH Turnaround Contract — India

4 APHsreplaced in a 20-day shutdown window

Project Context

The Challenge

Replacing four Air Pre-Heaters (APHs) across critical Hydrogen and Delayed Coker units within a strict 20-day shutdown. The project required coordinating parallel scopes, a single heavy crane, and a 150-person workforce at a major refinery.

Engineering Delivery

Navsar's Technical Solution

Acting as Principal Contractor, delivered end-to-end engineering, HSE-certified site prep, and direct field management.

Verified Outcome

Business Impact

Successfully overcame mobilization delays to ensure on-time delivery with strict QA/QC compliance.
