<p>The Trans Sahara Gas Pipeline (TSGP) is a main gas transmission pipeline from Calabar in Nigeria to Beni Saf in Algeria. The dimension is 48" with a design pressure of 100 barg, which gives an overall transport capacity of 20 bcm/year (60mcm/day). The overall length of the pipeline is ca 4400 km, of which 1037 km in Nigeria, 841 km in Niger, 2303 km in Algeria and 220km Subsea from Algeria to Spain.  </p>
<p>The pipeline route follows the route of the Trans-Nigerian pipeline from Calabar to Kano in Nigeria. It is expected that the pipeline will be connected to the Nigerian gas transmission system. In Niger, it is expected that there will be off-take points in the south for power production plants and in the north close to the mines for power production and potentially for direct use in the vehicles and machines used in the mining activities, where gas could replace oil. In Algeria, the pipeline follows the Trans-Saharan highway to Hassi R´Mel, where the pipeline will be connected to the northern part of the integrated gas transmission system. From Hassi R´Mel, the pipeline will follow a number of existing pipelines to Beni Saf. The middle part of the Algerian section will run in the same horizontal level as pipelines from In Salah and In Armenas. More than half of the pipeline section is hence to be constructed in well-known terrain and conditions in respectively Nigeria and Algeria. Only the middle section, from Kano in Nigeria to the south of Algeria, via Niger, is to be considered as new terrain for large diameter pipeline construction. Finally a 220km subsea pipeline would be constructed from Beni saf in Algeria to Spain in order to supply gas to the European market.</p>
