Nyhamna is a Shell-operated processing plant for natural gas from the Ormen Lange field in the Møre Basin in the Norwegian Sea. The gas is transported from the plant to England through the 1 200-kilometre Langeled gas pipeline. Nyhamna is being expanded to also be able to receive gas from the Aasta Hansteen field in the north through the new Polarled gas pipeline. After the upgrade, the plant's capacity will increase by approximately a third.
AF has faced some complex issues at Nyhamna and has had strict security requirements. One example is when the project needed to excavate a trench for the new pipeline, which extends 400 metres into the sea and is up to 20 metres under water.
An ordinary method would have been to blast the rock away, but because the operation was carried out next to a fully-operational pipeline, 600 cubic metres of rock under water had to be removed without blasting. The AF team's solution was to drill several holes in the rock and then use a pick and chisel to remove the rock.
