Costs are driven higher and schedules are extended because we experience QC problems during the execution phase of oil and gas development projects. The issues that we encounter with ATEX compliance, Flange Management, Piping System Cleanliness, Coating Systems, Regulatory Compliance etc. are common to almost every project. At the same time, our QC strategy remains the same on every project.
Something needs to change.
When Quality Assurance arrangements are not robust or when Quality Controls fail, the consequences are not always immediately apparent. Construction activities may progress unaware of impending issues only to discover later, that protective coatings have not been applied properly, or a welder is not qualified, or material traceability has been lost...
While traditional quality auditing techniques will identify key deficiencies during the Vendor or Yard qualification process, this will not identify the day to day issues that will inevitably arise during project execution. When Vendors and Contractors are faced with cost, time, resource or competency issues things can and do get missed.
Traditionaly, Oil & Gas Companies and EPC Contractors rely heavily on Inspection & Test Plans. The more activities that are annotated with Client Hold and Witness points, the more comfort we have that all will be well. History however tells us a different story, this means of ensuring contract specification compliance has not served us well in the past, nor will it in the future.
By their nature, information gathered by attending an ITP Witness or Hold point is historical and therefore backward looking. However, we now have the means to gather data on Vendor and Contractor performance from structured QC surveillance activities, this data provides information that indicates where things are likely to go wrong in the future so that we can take preventative action to ensure that facilities start-up is flawless.
