Abstract
A subsea foundation comprises at least one mudmat having a top panel and a skirt depending from the top panel to be embedded into seabed soil. At least one auxiliary plate 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 foundation may be used to restrict movement of an elongate subsea element, such as a pipeline, relative to the seabed.
