Abstract: The present invention provides a system for auto-alignment and tensioning of flexible pipes (24) in a stationary production unit, said system comprising (i) at least one tensioner (10) comprising an upper cone (10s) and a lower cone (10i), the upper cone (10s) and the lower cone (10i) being fixed together and forming a symmetrical double cone structure provided with an internally hollow cylindrical opening suitable for passage of a flexible pipe (24), (ii) at least one supporting fork (12) with pivoted connection to the at least one tensioner (10) and (iii) at least one coupling device (16) which, at a first end, is connected detachably to the at least one supporting fork (12) and, at a second end, is connected to the stationary production unit. A method for installing flexible pipes by means of said system is also provided.
