Gassco Project Manager Leif Solberg, who was formerly employed by Statoil as the Langeled Project Manager, said that the sheer size of the pipeline project made it a unique project to work on – not only in terms of length, but also in diameter.
“The pipelay barge needed to be upgraded to be able to lay 44 inch diameter pipe, and the 1,200 km length of the pipeline required pigging over long distance,” he said.
The pipeline project began in 2003, with pipelay taking place in 2005 and 2006. The project was engineered by Snamproggetti, with Acergy and Allseas contracted for pipelay, and Subsea Seven and Technip undertaking the tie-in work.
At peak, approximately 4,000–5,000 workers were employed for the project, with a total of 70–80 vessels involved, including three laybarges.
Mr Solberg said “There were 25 different nationalities represented on the laybarges. We focused on good co-operation and introduced a common goal in health, safety and environment (HSE) throughout the construction work, which resulted in good and efficient team work.”
