PROCESS & OPERATING PHILOSOPHY
Detection coverage, alarm voting, ventilation/shutdown and suppression interfaces. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
ELECTRICAL & AUTOMATION
Fire & Gas Detection
Detection and executive action designed around credible gas, flame, smoke and heat hazards.
MAIN EQUIPMENT & PACKAGE LIMITS
Gas/flame/smoke/heat detectors, controllers, beacons, sounders and panels. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
CRITICAL DESIGN INPUTS
Plant load/I/O lists, voltage and network philosophy, hazardous-area classification, availability targets, control narratives, package interfaces and cybersecurity requirements.
ENGINEERING DELIVERABLES
Detector mapping, coverage study, cause/effect, layouts, I/O and testing procedures. The package also includes line/equipment lists, relief and utility summaries, layouts or 3D interfaces, vendor-document requirements, inspection plans and commissioning inputs as applicable.
AUTOMATION, SAFETY & HSE
Protection/selectivity, redundancy, fail-safe states, alarm management, segregation, earthing, functional-safety validation, FAT/SAT and controlled software backups.
APPLICATIONS & PERFORMANCE BASIS
Process areas, tank farms, buildings, loading and enclosed modules. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
CODES, STANDARDS & QUALITY BASIS
NFPA 72, IEC/EN detector standards and project fire philosophy. The contractual code basis is selected by destination and client specification. ASME/API/TEMA, EN/DIN and GOST/EAC requirements are not mixed without an approved code-equivalency and authority review.
CONTRACTUAL CODE BASIS
NFPA 72, IEC/EN detector standards and project fire philosophy.
