The contract covers the design, manufacture, delivery and installation of DTS (distributed temperature sensing) and RTTR (real time thermal rating) cable monitoring systems, suitable for the 220kV sea cables and 380kV land cables that will connect offshore AC platforms with land stations and the existing 380kV grid. The systems will be used for cables installed on the west coast of the Netherlands and in the Dutch North Sea.

The link will take the form of submarine and land-based sections at both the Malta and Gozo ends. The proposed route will start at the Xewkija industrial estate, proceed 3.6km to the shore at Tal-Fessej, then underwater for a distance of 13km, landing at Golden Bay before terminating 4.3km away at Żebbiegħ. To minimize disturbance, both on the rocky foreshore and shore end at Mġarr ix-Xini, it is being proposed to use an unemployed pipeline as the cable duct, with the end emerging into the water around 10m below sea level. years after a
