Starting up equipment in downstream operations

Business Sectors (Suites): Downstream Operations
Developed by: Cogent
Approved on: 29 Mar 2019


This standard is about your contribution to starting up equipment. This must include rotating equipment, non-rotating and storage equipment, heat transfer equipment, control equipment.

This standard deals with the following:

1 Prepare to start up
2 Start up equipment
3 Communicate information during start-up
4 Correct abnormal start-up conditions

During this work you must take account of the relevant operational requirements and safe working practices AS THEY APPLY TO YOU.

This Standard is suitable for those working in the downstream fuel environment.

Adapted from Unit 2 of Refinery Field Operations NOS – version April 2005

Performance criteria

You must be able to:

P1 obtain relevant authorisation for start-up to proceed
P2 correctly identify equipment and checked status
P3 correctly follow operational procedures for checks and tests
P4 identify the locations of emergency isolation valves and their reset mechanisms
P5 identify any discrepancies between the plant drawings and the procedures
P6 report any discrepancies to the appropriate personnel
P7 correctly line up the equipment
P8 inform appropriate personnel that start-up is imminent
P9 correctly start up equipment in accordance with specified procedures
P10 achieve operational conditions at each stage before proceeding to the next stage, responding and reporting any exceptions or abnormal conditions
P11 achieve normal operating conditions within required timescale
P12 inform relevant personnel when start-up is complete
P13 complete all relevant documentation
P14 identify abnormal conditions at each stage of the start up process
P15 take prompt and appropriate action to correct the abnormality, including the procedures required if the abnormality continues and does not respond your corrective actions
P16 identify the impact of the abnormality on other areas and inform relevant personnel
P17 work safely in accordance with operational and safety requirements
