ALMA Provides Smarter Gas Pipeline Aerial Survey

摘要

Gas transportation companies have a wide variety of choices to make concerning pipeline inspections. Aerial technologies that include measurement of gas concentration and recording capabilities are gaining ground in this regard; one of the conventional systems is called aerial laser methane assessment, or ALMA for short, but how does it work? Dead, brown vegetation that has been starved of oxygen is a reliable sign of a gas leak. It is generally observed by an inspector viewing the corridor from a helicopter. This method can become more sensitive and comprehensive with the attachment of a small piece of technology to the helicopter.
