Calculate the temperature correction for changes in pipeline temperature during the pressure test (DNVGL-RP-F115 Appendix C).
The test pressure is affected by changes in pipeline and fluid temperature during testing. For subsea pipelines the pipeline temperature should be allowed to stabilise to the ambient sea waer temperature. Use the unrestrained option for risers, spools, and piping, or use the restrained option for pipelines.
