Chennai is the gateway to South India's refinery belt — CPCL Manali, HPCL Vizag, and MRPL Mangalore. Pathnovo extracts structured data from P&IDs, generates instrument indexes, and digitizes HAZOP registers for OISD 118 compliance. We serve EPC contractors and owner-operators across the Chennai–Vizag–Bangalore triangle.
Yes. OISD 118 requires periodic HAZOP studies for all petroleum installations in India. Pathnovo digitizes HAZOP registers from any format, maps actions to current P&ID revisions, and generates OISD 118-compliant output. We have specific experience with CPCL and South Indian refinery documentation standards.
