PROCESS & OPERATING PHILOSOPHY
DOL/VFD/soft-starter control, protection, interlocking and communications. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
ELECTRICAL & AUTOMATION
Motor Control Centers (MCC)
Motor power, protection and control coordinated with process operation and maintenance.
MAIN EQUIPMENT & PACKAGE LIMITS
MCC lineups, starters, VFDs, protection relays, metering and network interfaces. 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
Motor list, schematics, I/O mapping, cable schedule, FAT and settings. 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
Pumps, compressors, fans, mixers and packaged equipment. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
CODES, STANDARDS & QUALITY BASIS
IEC 61439/60947 and project electrical specifications. 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
IEC 61439/60947 and project electrical specifications.
