The crosspiece has reinforcing members at least partially mechanically connectable to said corner portions. | 03-24-2016 |
20160115667 | Device For Anchoring A Raceway Mounting Of A Seabed-To-Surface Facility - A device having a rigid structure immersed in a subsurface by floats and anchored to the sea bottom by tension legs, the device suitable for supporting troughs in a bottom-to-surface connection installation, having a plurality of flexible lines extending to the sea bottom, the flexible lines being supported by the troughs, the trough support structured is connected to a base resting on and/or anchored to the bottom of the sea by a plurality of n tension legs tensioned in parallel, by the float, n being not less than six, each of a plurality of p tension legs from the n tension legs, where p is not less than (n−2) being connected at one of its ends to a distance-varying device secured to the base or to the support structure, the distance-varying device suitable for varying the distance between the support structure and the base. | 04-28-2016 |
