A protective mat for an elongate object such as a pipeline, umbilical, hose or cable, said mat comprising an array of negative buoyancy elements, each element being joined to at least one adjacent element by respective flexible connections to define an articulated unitary mat, said elements being arranged in a plurality of rows and columns such that the mat has a square or rectangular overall profile in plan view, wherein the adjoining lateral sides of the elements in at least one pair of columns lying adjacent to one another are arranged on a common axis at an acute angle to the opposite lateral sides of the elements in each of said at least one pair of columns, such that the elements may be separated from each other along said common axis between adjoining lateral sides of the elements in said at least one pair of columns to separate the mat into two or more wedge shaped segments. |
