ABSTRACT OF THE DISCLOSURE An offshore pipeline installation comprises a wellhead base and a pipeline anchor connected together to form a unit which is lowered onto a seabed. The anchor is pivotably posi- tionable relative to the wellhead base about a vertical axis of a pilot tube. A pin pile is inserted through the tube and into the seabed to isolate the pipeline anchor from the wellhead and wellhead base in relation to forces generated in anchoring a pipeline to the pipeline anchor. The anchor is selectively positionable for alignment with pipeline means to be laid, and may include a socket mounted for pivotal movement about one or more, axis. The socket is operable to receive pipeline means laid away from the anchor. The anchor may further include a ramp which is inclined relative to horizontal. The ramp is positionable generally laterally relative to the lay path of the pipeline means so that pipeline means laid upon the ramp gravitates downwardly toward clamp means at the foot of the ramp.
