The Skaugum Tunnel (Norwegian: Skaugumtunnelen) is a 3,790-meter (2 mi) long railway tunnel in Asker, Norway, on the Asker Line. The tunnel runs between Asker Station and Solstad and was built as part of the first stage of the Asker Line, between Asker and Sandvika. Construction started in February 2002 and the tunnel opened on 27 August 2005. The tunnel was built by Mika for the Norwegian National Rail Administration using the drilling and blasting method with one crosscut. During construction there was one blasting accident. Since the tunnel opened, there have been problems with leaks damaging the infrastructure. The tunnel has double track, is electrified and allows for a maximum speed of 160 kilometers per hour (99 mph). The cost to build the tunnel, excluding the infrastructure, was 450 million Norwegian krone (NOK). The tunnel has accelerated intercity and regional traffic west of Oslo and freed up capacity for the Oslo Commuter Rail on the old Drammen Line.

The Subsea Valley(SSV) geographically consists of Fornebu, Sandvika, Asker, Tranby, Drammen, Hokksund and Kongsberg, totaling approximately 75 km in length. The SSV consists of 184 firms and currently incorporates three of the five major subsea engineering companies that compete in the industry. The major engineering companies within the SV are FMC Technologies, Aker Solutions and GE Vetco. With regard to subsea production systems, Norwegian suppliers have gained global market shares in the range of 60-70%, and companies such as FMC Technologies, Aker Solutions and GE are truly global players within this segment. The competitors located outside the cluster are Cameron and DrillQuip. In a recent report by TESS it is stated that in addition to the companies, which are present in the SSV area, as many as 600 companies are in one or another way connected to the valley. The three central companies in Subsea Valley – FMC Technologies, Aker Solutions and GE Vetco – are supplying oil & gas extraction equipment to such hydrocarbon operators as Statoil, Exxon and Petrobras.
