  1. Isolation Procedure Presentation Ref: HQS-013-02-012 – Isolation PermitProcedure Doc Control No: HQS-013-17-005 Rev. 1

  2. Learning Objectives • At the completion of this session, personnel should be able to: • Explain why we use a system of isolation • Describe how to apply the isolation permit system on a Songa facility, to achieve secure isolation of plant & equipment • Discussthe equipment, procedures and administration involved with the isolation permit system.

  3. Isolation Procedure Corporate Level • The HQS-013-02-012Isolation Permit Procedure is located on, Level 4 - QSMS. • The HQS-013-04-009 Isolation Permit form is located on, Level 7 - Corporate QSMS. Regional Level Rig Level

  4. What is an Isolation System? • A system to ensure that equipment is properly de-energized, (isolated), prior to conducting work on it. • The effectiveness of an isolation system depends on the adequacy of other arrangements, • including permit-to-work, • operating procedures, • training and competence, • management of change and contingency plans.

  5. Lock Out / Tag Out (LOTO) • LOTOhas become an industry standard for isolation. • When performing LOTO, there should be isolation from the energy or power source so that the isolator, (i.e. switch) is locked in position, (e.g.. by a padlock), and a tag should be used to indicate that maintenance work is in progress. • Any stored energy (i.e. hydraulic or pneumatic power) should also be dissipated before the work starts.

  6. What are the Different Types of Energy You May be Exposed to in Your Area of Responsibility? • Mechanical • Electrical • Hydraulic • Pneumatic

  7. What are the Different Types of Energy You May be Exposed to in Your Area of Responsibility? • Chemical • Thermal • Potential

  8. Who are the people involved in the process of Isolating plant of equipment? • Permit Coordinator is responsible for: • coordinating the issue, logging and return of all Permits to and from the Permit Control Centre; • maintaining the Permit Board; • issuing all primary locks • ensuring that Permits are duly signed off

  9. Who are the people involved in the process of Isolating plant of equipment? The Responsible Persons or Head of Department is defined as the person operationally responsible for the system in question. On Songa facilities the Responsible Persons are designated by the OIM as per the Rig Organisation Chart. Note: The OIM shall designate a night shift position to fulfil the HOD’s / responsible persons isolation permit responsibilities.

  10. Who are the people involved in the process of Isolating plant of equipment? • Supervisor; the person in charge of the worksite, is responsible for the following: • Ensuring that all approvals are obtained, prior to the start of work; • Communicating to involved personnel clear information and instructions regarding the scope of work; • Completing relevant sections of the Isolation Permit; • Verifying Isolations are completed in accordance with the Isolation Procedure;

  11. Who are the people involved in the process of Isolating plant of equipment? • Competent Person:An Authorised Competent Person is a person who has been designated, authorised and suitably trained and qualified to be in charge of all isolation / de-isolation of machinery and equipment).

  12. When do we use Locks and Tags? • Locks will always be used in conjunction with isolation tags and personal danger tags. • An “isolation” tag will be applied when a lock is placed to identify the Competent person carrying out the isolation and the relevant Isolation Permit number it relates to. • A “personal danger” tag(s) will be attached to all locks used. A tag will be attached for each individual performing work on the machinery or equipment.

  13. What Type of Locks and Tags Must be Used When Applying an Isolation Tag? Samples only • Safety padlocks (associated keys must have clear identification). • Other Equipment • Personal Danger tags • Isolation tags • Lock out Devices

  14. What Types of Jobs Would Require You to Perform or Request an Isolation? • When you must either remove or bypass machine guards or other safety devices, resulting in exposure to hazards at the point of operation. • When you are required to place any part of your body in contact with the point of operation of the operational machine or piece of equipment. • When you are required to place any part of your body into a danger zone associated with a machine operating cycle or system operation.

  15. What Types of Jobs Would Require You to Perform or Request an Isolation? (Cont’d) • When you are required to break the integrity of a normally-pressurized system or piece of equipment, or • When you are required to carry out work that has the potential to compromise integrity of a normally-pressurized system or piece of equipment,

  16. What is an Isolation Permit? (IP) This is a document that details and records the isolations required for a given piece of equipment or system.

  17. When is an “Isolation Permit” Used? • There are two scenarios where a Isolation Permit is required: • If equipment or machinery must be isolated from energy sources in order to perform work on it or a system it effects. • If equipment or machinery is in an unsafe condition and needs to be isolated to either protect it from further damage or from causing damage or injury to other equipment, systems or people.

  18. How is the “Isolation Permit” Raised? • Head of Department completes Box 1. • Systems to be isolated, work to be undertaken. • Appointment of a Competent person to undertake isolation and actions to be taken.

  19. Competent Person – Isolation details • Competent person details the isolation methods used and verifies the isolation.

  20. Supervisor – Verification of Isolation • Verifies that the system / equipment specified on the permit has been isolated.

  21. Completion of Work - Supervisor • Supervisor checks that the work specified has been completed or not completed. • That the work area is made safe. • If testing is required. • If long term Isolation is required.

  22. Head of Department – Authorization for De-isolation • Head of Department Authorises de-isolation, by competent person - if work is completed, permits withdrawn and safe to do so.

  23. Competent Person – Confirmation of De-isolation • Confirms all de-isolations have been performed and the system / equipment has been returned to its normal operating state.

  24. Head of Department – Long Term Isolation • States Reason for Long Term Isolation and Authorizes.

  25. Permit Coordinator • Long Term Isolation in effect. • Entry into isolation log. • Closure of associated work permits. • Long Term Isolation Permit has been closed.

  26. Long Term Isolations If the Isolation Permit is to remain in place (i.e. awaiting parts or further work), the Isolation Permit should be marked as being a Long-Term Isolation

  27. How Does the Isolation Permit Link to the PTW System? • The IP is linked to the Permitby reference on the PTW form.

  28. How Does the Isolation Permit Link to the PTW System? • The PTW cannot be authorised until the Area Supervisor has: • identified requirement for isolation, • planned the isolation, • selected competent persons to perform isolations, • verified isolation are in place and logged the isolation permit and attached to PTW, if applicable.

  29. De-Isolation • Only AuthorisedCompetent Persons are to de-isolate equipment and remove the lock from the isolation points or lock box. • Verification that the work is complete / discontinued and associated work permits withdrawn must occur prior to de-isolation. • Make sure the equipment is safe to operate by removing all tools from the work area and making sure the system is fully assembled.

  30. De-isolation • Conducting a head count to make sure everyone is clear of the equipment. Also notify everyone in the work area that lockout/tag out is being removed. • Check with the permit control center that de-isolation does not conflict with any other permit to works or other work activities. • When de-Isolating the equipment, ensure all personnel remove their locks and tags. • Verify that equipment has been returned to its normal operating state.

  31. De-isolation (for test purposes only) • Equipment may be de-isolated for test purposes only during the life of the Isolation Permit. • Supervisor’s must request permission for de-isolation from the Head of Department. • The Head of Department will then request de-isolation for test purposes only, from the person in charge of the de-isolation. • On completion of testing, competent person will re-isolate the equipment.

  32. Use of LOTO by Contractors • Third Party Contractors must use the Songa LOTO system. • Third Party Contractors must understand the Songa system and complete the required training before using the system. • All isolations will be completed by authorised Songa competent person.

  33. Shift Change • If the work lasts more than one shift, lockout/tagout protection must not be interrupted. • As part of the shift change handover, personal locks and tags must also be changed over. This allows the isolations to be verified as still intact.

  34. Removal of Lock by Management • The OIM or his delegate may remove a lock once it is confirmed the person who placed the lock has left the rig. • Prior to removal, the OIM or his delegate will review the appropriate PTW and IP and go to the worksite to ensure it is in a safe condition.

  35. Competency Assessment – Knowledge Questions • Why must we use a system of isolation? • On what part of the equipment or machinery are lock out devices applied to? • Where are locks issued from and by whom? • Who must use a Primary Lock or lockout device and what tag(s) must be attached to it? • Where would individual work team members place there Personal Danger Tags? • Is a Isolation Permit required to isolate equipment? • What information is recorded on an “Isolation (Equipment Locked Out) Tag”? • Who decides / authorises a “Competent Person” to perform an isolation? • How is the Isolation Permit referenced to the Permit to Work? • What is a lock box used for? • Who completes the Isolation Permit with the Competent Person. • What is the process to be followed, when changing an isolation to long term?

  36. Competency Assessment – Application of Skill • Apply a personal lock and personal danger tag, as directed by the assessor.
