Discussion Of Hydrostatic Testing For Subsea Pipeline's Integrity

During the era of energy economy, the petro industry has been developed very quickly. The subsea pipeline is called"lifeline of sea", it is very important to document integrity of subsea pipeline, to detect all kinds of defects and hidden trouble, to obtain higher safety level for subsea pipeline's service.This document introduces how to use methods of hydrostatic testing to document subsea pipelines integrity. It introduces the background of subsea pipeline's hydrostatic testing, describes the hydrostatic testing procedure and its key possible critical points on offshore site, analyzes the advantage and limitation of hydrostatic testing, introduces the new ideas about the hydrostatic testing of pipeline, shows other relative methods to inspect the hidden trouble and defects along pipeline, and gives recommendations to validate subsea pipeline's integrity.
