A clamp assembly and a clamp element especially for clamping buoyancy elements to pipeline risers

摘要

A clamp element (10) has a T-shaped body with laterally extending portions (24) on either side of a radially projecting tang (20). A plurality of the clamp elements (10) are joined together in an array to form a clamp assembly (40) with the tangs (20) facing outwardly. Straps (42) having looped ends (44) are disposed around the array. The looped ends (44) of the straps (44) are engaged with respective cross bar members (46). Adjacent cross bar members (46) are connected together by means of a threaded bar (50) which is arranged to tighten the straps (42) around the array of clamp elements (10).
