A method of converting a subsea laying system of a surface vessel from a laying mode to an abandonment or recovery mode Includes clamping at least one tubular sleeve in at least one clamp of the laying system. A winch wire can then run longitudinally through the or each clamped sleeve when suspending an elongate subsea element such as a pipe string during abandonment or recovery operations. The sleeve protects gripping pads of the clamp from damage due to dashing with the wire and so makes it unnecessary to remove the pads in preparation for abandonment or recovery.
