Cold Loop Checks: Once pre-commissioning works are complete, we initiate cold loop checks to verify the integrity and functionality of instrumentation systems before they are energised.
This process includes:
Verification of Connections: We inspect and verify all electrical and signal connections in a de- energised state, ensuring that wiring and terminations are correct.
Hot Loop Checks: After cold loop checks, hot loop checks are performed to validate the operation of instrumentation systems under live conditions.
This includes:
Operational Testing: We perform tests while the system is operational, ensuring that instrumentation accurately responds to process conditions.
Signal Verification: Confirmation that signals are transmitted correctly between field devices and control systems, ensuring data integrity.
Proof Testing: Following successful hot loop checks, HBI conducts proof testing to validate the performance and reliability of safety-related systems.
This involves:
Functional Testing: We perform tests to confirm that safety instrumented functions
operate correctly, ensuring that systems react appropriately
to hazardous conditions.
Documentation of Results: All proof test results are documented to provide a record of compliance with safety standards and regulations.
SIS Functions Checks:
Safety Instrumented Systems (SIS) checks are critical for ensuring that safety functions perform as intended.
Our SIS functions checks include:
Comprehensive Testing: We test all safety functions to verify their correct operation, ensuring they can effectively mitigate risks in the event of an emergency.
Regulatory Compliance: HBI ensures that all SIS checks are performed in accordance with relevant safety regulations and industry standards.
Hot & Cold Commissioning Test Plans: Throughout the commissioning process, HBI develops detailed test plans for both hot and cold commissioning phases.
These plans include:
Test Objectives: Clearly defined objectives for each test, outlining what needs to be verified during commissioning.
Procedures and Protocols: Step-by-step procedures for conducting tests, including safety protocols and acceptance criteria.
Scheduling: Coordination of test schedules to align with project timelines and resource availability.
Punch Lists: As part of our commissioning process, we utilize punch lists to track outstanding tasks and issues that need to be addressed before project completion. Our punch list services include:
Identification: During the commissioning phase, we identify any deficiencies or incomplete work that must be rectified.
Documentation: Each item on the punch list is documented clearly with descriptions and responsible parties assigned for resolution.
Follow-Up: HBI conducts follow- up inspections to ensure that all punch list items are addressed satisfactorily before final project sign-off.
As-Built Completion:
Upon successful commissioning, HBI provides as-built documentation to reflect the final configuration of the installed systems.
This includes:
Documentation Updates: All drawings, schematics, and specifications are updated to accurately represent the completed installation.
Client Handover: Comprehensive as-built documentation is handed over to the client, ensuring they have a complete record of the system for future reference and maintenance.
