A method of installing a subsea foundation 1 is provided. The method comprises providing a suction anchor 2 having an inner member 6, which may be a pipe for a well, and an outer suction skirt 4 located around the inner member. The inner member protrudes from the outer suction skirt. The suction anchor is moved towards a seabed so that the inner member penetrates the seabed before the outer suction skirt. The suction anchor is then further moved towards the seabed until the outer suction skirt reaches the seabed, before the suction anchor is sucked into the sea bed. A subsea foundation (100, Fig 8) that comprises a plurality of suction anchors, at least one of which provides a foundation for a subsea device, is also disclosed.
