History

Construction of the main pipeline, the Frigg UK pipeline, started in 1974 and was completed in 1977. It was built to transport natural gas from the Frigg gas field to the United Kingdom. Because of technical limitations, it was decided to build two parallel pipelines, one (the Frigg UK pipeline) by the United Kingdom and one by Norway (former Frigg Norwegian Pipeline, now Vesterled). Even in British waters, until 1998 both pipelines were in Norwegian jurisdiction.
