Commissioning is the defining stage where systems come alive. GrandTotal Energy Services Limited (GTES) employs a Systematic Commissioning Methodology (SCM) that encompasses pre-commissioning, commissioning, and start-up validation for both greenfield and brownfield projects.

Key Activities and Capabilities:

• Factory & Site Acceptance Testing (FAT/SAT):
  Conducted in accordance with ISA S5.1, IEC 61508, and IEC 61131 standards, ensuring all instrumentation loops, logic sequences, and interlocks function precisely as designed.
• Loop Checking & I/O Validation:
  Comprehensive verification of signal integrity, control logic validation, and calibration verification using industry-grade calibrators and simulators (e.g., Fluke, Beamex).
• Dynamic Simulation & Logic Verification:
  Utilisation of HIMA SILworX, Honeywell Experion, or Siemens PCS 7 simulation environments to validate cause & effect matrices, emergency shutdown sequences, and F&G logic prior to system energisation.
• Training & Handover:
  Commissioning includes structured O&M training, preparation of as-built documentation, and formal system handover as per client QA/QC procedures.
