POPULAR SAMPLE Copied 51 times
Hot Commissioning. Hot commissioning is where the plant processes are placed into operation in conjunction with the control system. The Contractor notifies the Project Manager that cold commissioning is complete and requests the commencement of hot commissioning. The Contractor is responsible for the commissioning of the complete control and protection system, including the final control elements such as: Drives, Switchgear, Interposing relays, Actuators, Solenoid operated valves, Existing actuators and their interposing relays The commissioning activities are carried out in conjunction with the Supervisor. The Contractor is responsible for the hot commissioning of all the Plant and equipment forming part of the Works to satisfy the requirements of the Works Information. The Employer is responsible for Plant preparation for hot commissioning. However, the portion of the equipment, which cannot be commissioning separately from other Plant, the commissioning is at the discretion of the Project Manager for the particular stage of commissioning. Commissioning activities for LPS are to be executed in accordance with the standard 240-5636376 on site commissioning for LPS standard. In those cases where various components (existing or new) are connected to form an integrated system, the Contractor, at the time of commissioning, carries the responsibility for the correct functioning of the whole system. If a defect is identified in the equipment interfacing or external to the Contractor’s scope, the Contractor directs the Project Manager’s representative/s to rectify the defect.
a. The following commissioning records are kept as a minimum: Quality control and commissioning procedures and certificates. Inspection and Test Plans (ITP) Calibration certificates CONTRACT 36 ECC3 COVER PAGES Instrument Installation Quality Check Sheets Design reviews and factory inspections, if applicable Loop check sheets Cubicle, instrument and HMI systems power supply connection and commissioning check sheets
a. Each instrument or device has its own installation quality check sheet for quality purposes, i.e. one check sheet is not used to represent a group of instruments installed.
Hot Commissioning. Control components shall be made available for control and monitoring the plant during its re-commissioning. Cold commissioning would include most of the works namely, all the cable installations and terminations, field equipment installations and termination, commissioning of the PLC, Local Control Desk. These activities will be possible since the plant automation and monitoring is not available due to flood damage. The flood damage has required the drives to run from the Switchgear local operation and not through the C&I control system and therefore hot commissioning will primarily be the final testing and commissioning of the Switchgear drives into the C&I control system Performance and Acceptance tests shall be performed on all areas of the DWD Plant. The tests include all analogue controls, interlocks, safety protections, control loops, binary control, sequence control and interfaces. After satisfactory completion of installation and commissioning of the control and monitoring system it shall be demonstrated that the control and monitoring systems correctly performs in the following modes: • Verification of related protections is a prerequisite before plant is released to run in a manual or automated mode. • Plant operated manually from the Local Control Desk as well as Local Control Stations. • Plant operated automatically (start-up, sequential control and shutdown) with all the remote monitoring / supervisory functions at the Local Control Desk. The plant shall then run for an unbroken period of 164 hours without a hardware or software malfunction. During this period any and all control modes may be exercised.
Hot Commissioning. A commissioning check list shall be submitted to the Engineer for approval prior to any commissioning work being undertaken.
Hot Commissioning. 1. Hot commissioning starts after cold commissioning is complete.
2. The plant is commissioned by running the system fully manual and testing each piece of Plant and Material for full functionality in each mode of operation
3. The Contractor in conjunction with the Employer performs the commissioning of the DCS Control System and allows for the following tests to be completed:
a. Full function tests as per this specification
b. testing online and offline
c. Code compliance testing as per Code requirements
4. Due to possible constraints from the Employer, the Contractor allows for his commissioning engineer to be available continuously during each hot commissioning activity.
5. The commissioning engineer is officially certified by the Contractor as being qualified and experienced to commission the DCS system and be able to make the necessary software updates as may be required onsite during hot commissioning.
