Abstract
A protective cover for a subsea elongate element, such as a pipeline, has an open end and a barrier attached to a cover to extend across and close an open end. The barrier is flexible to conform to and surround an elongate element extending from under the cover and protruding through the barrier. This prevents rocks of a rock berm from getting under the cover through the open end.
