Abstract

The anchorage device is for use when there is a risk of damage to underwater pipelines or other structure which may be located at the anchorage point. The anchorage device is lowered vertically by a cable controlled by a winch. It comprises a deformable body (6) comprising an envelope which may be permeable or impermeable to water, filled with a particulate material, e.g. shot or sand, so that as the body is lowered onto the sea bed, for e.g. onto a pipeline on the sea bed, it deforms around the pipeline so that the full wt. of the body is not applied to the pipeline.
