AERIAL SURVEYING FOR GAS PIPELINES

摘要

LEAKS IN GAS TRANSPORTATION PIPELINES can present an incalculable risk for operating companies. Leaks can lead to accidents; the escaping gas is an expensive loss; and lost gas often severely harms the environment. In addition to simply finding leaks, pipeline operators must identify possible threats as soon as possible, before they present a real risk. Pipelines are one of gas transport companies' most important assets and certainly their most safety-sensitive. Gas transport companies have a variety of choices concerning pipeline inspections. Aerial surveys are considered state-of-the-art and are often used in addition to walking surveys with traditional gas sensors. While these walking surveys deliver reliable results, they are time-consuming. Documentation is sometimes still recorded with a highlighter on paper maps, and the walking procedure carries a high risk for occupational accidents. Smart aerial technologies that include measurement of gas concentration and recording capabilities are sustainably gaining ground.
