The aim of this project is to carry out a complete review of the latest information relating to the defect tolerance and axial stresses on pipe girth welds during excavation related activities; and propose revisions for methods applied to working on pipelines containing defective girth welds or girth welds of unknown quality.A phased approach is proposed in order to deliver results efficiently and as they become available. The overall project scope has been divided into two stages which are listed below. Phase 1 involves in undertaking literature review and, Phase 2 involves in undertaking engineering assessments as required. Phase 1: Literature ReviewA literature review will be undertaken to determine the scope for improvement on working on defective pipelines. A summary report will be issued covering all the work undertaken as part of the Phase 1. This phase of the work confirm the belief that sufficient benefit is achievable then only Phase 2 part of the project will commence.Phase 2: Engineering AssessmentsBased on the recommendations of the literature review, detailed engineering assessments based on the new understanding in the applicable fields of knowledge will be undertaken. One technical report will be issued covering the re-evaluation of the current state of knowledge. To carry out a complete review of the latest information relating to the defect tolerance and axial stresses on pipeline girth welds.
