West African Gas Pipeline Regulations, 2005 (L.I. 1814).
9. INVESTIGATION OF FAILURES General 9.1 The Operator shall establish procedures for analysing accidents and failures, including the selection of samples of the failed facility or equipment for laboratory examination, where appropriate, for the purpose of determining the causes of the failure and minimizing the possibility of a recurrence. 9.2 The Operator shall: (a) compile data on all failures and leaks for use in continuing surveillance; and (b) prepare a detailed analysis, especially of repeated occurrences when the analysis could be useful in minimizing a recurrence of the failure. Response to Incident 9.3 If a detailed analysis is to be made, rapid response will be necessary for gathering information and preserving the integrity of any specimens collected. Incident Data Collection 9.4 When a detailed analysis is to be prepared, a person at the scene of the incident should be designated to coordinate the investigation. Such person will be responsible for: (a) acting as a coordinator for all field investigative personnel; (b) maintaining a log of the personnel, equipment and witnesses; (c) recording in chronological order the events as they take place;(d) ensuring that photographs are taken of the incident and surrounding areas; (e) ensuring the notification of all appropriate governmental authorities; and (f) ensuring the preservation of evidence. Investigation Team 9.5 When a detailed analysis is to be prepared, the Operator shall designate a fully qualified investigation team. The investigation team should be qualified either by training or experience in the proper procedures for investigation of an incident. The investigation should include the following: (a) determination of the probable cause of the incident; (b) evaluation of the initial response to the incident; (c) the need for system improvements if necessary; and (d) the need for improvements in response, management and investigation of incidents. Specimens 9.6 The Operator will prepare a procedure for the selection, collection, preservation, labelling and handling of specimens. Procedures for collecting metallurgical specimens should include precautions against changing the granular structure in the areas of investigatory interest (e.g., avoid heat effects from cutting and outside forces due to tools and equipment). When corrosion may be involved, procedures may be necessary for proper sampling and handling of soil and ground water specimens. Procedures controlling the cutting, cleaning, lifting, identifying and shipping of pipe specimens should be considered for preservation of valuable evidence on the pipe surface, and on any tear surfaces fracture faces, including making cuts far enough from the failure to avoid damaging critical areas of the specimen. 9.7 The number of specimens that need to be collected at the failure site may vary depending on the type and number of tests anticipated. A series of independent or destructive tests may require multiple specimens. If there is a need to confirm the pipe materials specifications, then additional pipe specimens should be obtained near the failure, but in an area of the piping where the physical properties and characteristics are unaffected by the failure itself. Other investigatory procedures may be utilized to confirm pipe material specifications. Testing and Analysis of Specimens 9.8 Recognized standard destructive and non-destructive techniques are the preferred means to examine test specimens. The testing methods used should be suited to the particular material being tested, and be pertinent to the failure investigation. 9.9 Analysis and data on failures should be compiled and reviewed. The need for continuing surveillance of pipeline facilities should be determined based upon the above analysis.
