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.

Abstract: The present invention provides a system for coupling between a bend stiffener (1) and a bell month (2) comprising a plurality of locking mechanisms (3), wherein each locking mechanism (3) is secured externally to the bell mouth (2) and comprises a movable lug (30) positioned such as to slope downwards, in which the lug (30) accesses the interior of the bell mouth (2) and is actuated by an elastic element (34) designed to exert pressure on the lug (30) in the direction of the interior of the bell mouth (2).
