Technical Control for Predictable Handover
Navsar is a global engineering firm specialising in Commissioning as a Service (CaaS) — an independent, outcome-based model that takes technical control of the commissioning phase and delivers an audit-ready handover. Navsar owns field outcomes; it is not an EPCM prime contractor and not a manpower or staffing supplier.
Why Commissioning Fails
Projects rarely fail because of equipment. They fail because execution logic breaks down across contractor interfaces. CaaS addresses these risks before startup pressure takes over.
Unclear Boundaries
Undefined system and subsystem limits lead to interface disputes and scope gaps between vendors.
Disconnected Vendors
Siloed engineering packages create unmonitored blind spots during multi-package energisation.
Paper Procedures
Static documents that do not reflect site reality or maintain real-time traceability.
Late Risk Discovery
Critical interface and logic failures uncovered only during energisation when schedule is compressed.
Incomplete Handover
Unauditable documentation and unverified punch lists delaying commercial operation.
Weak Execution Logic
Commissioning driven by project urgency rather than systematic engineering sequences.
How CaaS Works
A disciplined, digital framework taking technical control from pre-commissioning through to commercial operation.
Define & Systemise
We establish commissioning logic early: philosophy, subsystem boundaries, and interface mapping. Ambiguity is removed before execution begins.
Digitise & Prepare
All verification procedures, punch lists, and readiness tracking are pre-loaded into our Completions Management System (CMS) as a single source of truth.
Execute & Handover
Static and dynamic commissioning followed by a controlled, auditable digital handover. Systems reach first-time-right startup backed by verifiable proof.
Industries We Commission
Our methodology scales across the most demanding engineering sectors, ensuring standard execution regardless of operating environment.
Power Generation
Combined Cycle (CCPP), Simple Cycle, Thermal (Boiler / Burner conversions), and Diesel generation plants.
Hyperscale Data Centres
Critical power path, cooling validation, switchgear, and Balance of Plant (BOP) tier verification.
Metro Rail
Safety-critical traction power systems, signalling dynamics, ATS verification, and rail comms.
Oil, Gas & LNG
Compressor stations, refinery units, liquefaction processes, and distillation facilities.
Process & Chemicals
Specialised commissioning for chemical manufacturing, fertilizer, and high-hazard processing plants.
Marine and Offshore
FPSO topsides, floating LNG modules, and marine-spec high-power DC fast-charging systems.
Waste to Energy
Integrated waste management facilities, flue gas cleaning, and high-efficiency steam boilers.
Water Infrastructure
Large-scale desalination, high-pressure reverse osmosis, and wastewater treatment facilities.
