A subsea foundation 10 comprises at least one mudmat 12 having a top panel 18 and a skirt 20 depending from the top panel to be embedded into seabed soil. At least one auxiliary plate 26 is supported by the mudmat, the plate being deployable downwardly like a guillotine blade from a raised, retracted position in which the plate is held above a lower edge of the skirt into a lowered, deployed position in which the plate extends beneath the lower edge of the skirt to be embedded further into the seabed soil. The plate may be arranged to free-fall from the raised position under its own weight. The foundation may be used to restrict movement of an elongate subsea element, such as a pipeline 22, relative to the seabed. The invention may further envisage a method of fixing the subsea foundation and a subsea installation including the foundation and an elongate element such as a pipeline.
