RELIABILITY PROGRAM

 

Program: Atmospheric Storage Tank Inspection & Outage Scheduling

Owner: Inspection & Reliability Department

Responsibility: Area Inspector / Maintenance / Operations / Environmental

Governing Codes / Regulations / Industry Best PracticesAPI 653 (latest edition); Applicable Environmental Regulations and Permit Requirements
Internal ProceduresInspection Procedure MNT-INSP-022 (latest revision): Atmospheric Storage Tank Inspection & Outage Scheduling

Purpose:  To ensure compliance with environmental regulations and permit requirements, establish and maintain adequate inspection intervals, achieve best effort to prevent leakage, and guarantee the reliability of atmospheric storage tank equipment.

Work Process:

A.  TANK REMOVED FROM SERVICE

  • Central Maintenance Manager creates the necessary work orders to remove the tank from service.

B.  INSPECTION / RECOMMENDATIONS

  • External and internal inspections are performed by the Area Inspector.
  • Recommendations are issued to Terminal and Maintenance personnel.

C.  WORK SCOPE DEVELOPMENT

  • Maintenance develops the work scope to include inspection and engineering recommendations, operational issues, and environmental requirements.

D.  MAINTENANCE / REPAIR

  • Contractor(s) perform repairs according to the approved work scope, under the supervision of the Maintenance Supervisor.

E.  DOCUMENTATION / WORK ORDER CLOSURES

1.  Central Maintenance Manager closes out all work orders pertaining to the subject tank.

2.  As-built drawings are handled by design/engineering and filed in the designated records vault.

3.  Area Inspector documents all repairs and changes. These records, along with all initial recommendations and QC documentation, are filed in the tank files at the Terminal Area Inspectors’ office.

Future Outage Scheduling – Next Inspection Interval Criteria:

The following criteria will be considered when determining the next inspection interval:

  • History and corrosion rate
  • Environmental regulations and permit requirements
  • Service conditions
  • Code requirements and date of last inspection
  • Logistics
  • Design issues (e.g., Cathodic Protection System performance)

Outage Scheduling Criteria:

  • Reliability Department compiles data and sets the next required inspection per API and/or Environmental requirements.
  • Reliability Department notifies Terminal Operations and Maintenance of the next required inspection date.
  • Terminal Operations, Environmental, Reliability, Logistics, and Maintenance jointly set the next outage date on or before the date determined by Reliability. If the proposed date is beyond the API-recommended interval, the suggested outage date must be presented to and approved by the Risk Management Committee (RMC).
  • Next outage date is entered in the Master Overall Tank Outage Schedule.

Records / Reporting:

  • Tank Maintenance Group maintains the Master Overall Tank Outage Schedule.
  • Maintenance is notified of any changes in the scheduling of future tank outages.
