METHOD FOR INSTALLING UNDERWATER FOUNDATIONS FOR AN OFFSHORE DEVICE AND CORRESPONDING INSTALLATION ASSEMBLY

摘要

The invention relates to a method for installing underwater foundations (10) for an offshore device, said foundations comprising a support (20), notably of the jacket-leg type, for the device. The method involves a step of placing the support (20) on the seabed (S) and a step of definitively anchoring the support (20) to the seabed (S), said method further involving a step stabilizing the support prior to the step of definitively anchoring, by virtue of which the support (20) is stabilized while definitive anchoring is being performed.
