Abstract

A foundation (1) for installation on a seabed (B) below a body of water (W), having a bottom part (6), a main body (5) and a connection portion (15) for a support structure and/or an equipment unit and comprising a first ballast compartment (13; 13b) and a second ballast compartment (16; 13a); a portion (20') of the first ballast compartment (13; 13b) in a region of its upper end having an opening (19) between the first and second ballast compartments; a channel (20) extending between a region above the second ballast compartment (16) and into the first ballast compartment (13); and a conduit (18) extending between the second ballast compartment (16; 13a) and the exterior of the foundation (1). The invention also comprises a method of assembling the foundation and a method of installing the foundation ion a seabed.
