Safe work with flanges
OLF started the Gas Leak Project in 2003 to reduce the large number of leaks on the Norwegian continental shelf. Causal analyses showed that approximately 75% of all hydrocarbon leaks were due to human error.
Since 2003, the Gas Leak Project has contributed significantly to reducing the number of gas leaks on the Norwegian continental shelf. One of the measures in the project is this course, which is intended to increase the understanding and competence of everyone who works with and operates equipment on pressurized facilities.
