Carried out at the necessary four-year frequency, these surveys examine high pressure pipelines in detail; from the construction data to the ongoing operation and maintenance results.
The reports establish whether a pipeline may continue to operate up to a particular pressure and identify in an Action Plan any issues that need to be resolved by the operator.
Where there is a requirement to uprate the operating pressure,
cambrian services carry out the necessary review for the proposed conditions and identify any constraints and actions that are required before uprating can proceed. |
