A weighting clamp/anchor 10 for a subsea pipeline 24 comprises laterally-extending wings 14 and jaws 26 suspended beneath the wings. The jaws are arranged to embrace a pipeline that extends along a central longitudinal plane of the clamp in use. The wings may be in dihedral relation, inclined above a horizontal plane. The jaws may be spaced apart along the central longitudinal plane and may comprise a downwardly extending jaw hanging beneath the wings. The clamp is lowered onto the pipeline from above to engage the jaws with the pipeline. Lowering the clamp further applies weight of the clamp to the engaged pipeline to embed the pipeline further into the seabed and to bring the wings into contact with the seabed; this may form a trench in the seabed that has a cross-section corresponding to, and at least partially containing, the wings. The trench may have a v-shaped cross section. The engagement portions may snap-fit/interference fit onto the pipeline.
