Originally, NorSea Com was owned 50% by Telia and 50% by Enitel. After Enitel's bankruptcy in September 2001, Telia acquired the whole cable. In 2011, Tampnet AS acquired 100% of NorSeacom.
Installation started in 1998 and the cable was ready for service in 1999 with an initial capacity of a STM-16 system of 2.5 Gbit/s. Later, Enitel added a 16x10 Gbit/s wavelength-division multiplexing system. The cable contains 24 optical fibers.
NorSea Com-1 has a cable length of about 750 km between Draupner and Lowestoft. Between Draupner and Kårstø (ca 200 km) the system uses fibers in Statoil's submarine cable.
