Abstract

The invention relates to a seabed foundation () for an offshore facility, comprising a primary pressure chamber () connected to a primary pump () and one or more secondary pressure chambers () connected to one or more secondary pumps (). According to an embodiment of the invention, said primary pump is a suction pump and said secondary pump is a pressure pump. The invention further relates to a method () of installing said foundation on the seabed (), which comprises the steps of activating () said primary pump to create negative pressure in the primary pressure chamber (), so that the foundation sinks into the seabed, and activating () said one or more secondary pumps () to create positive pressures in the secondary pressure chambers (), so as to control the alignment of the foundation with respect to a substantially horizontal axis () during the sinking into the seabed.
