Chained Clamp Pipeline Repair Structure and Method of Use

摘要

Interlocking bend limiter sections are substantially mirror images of each other and are joined to form an interlocking bend limiter segment without use of fasteners by engaging each other's interlocking ends. An interlocking bend limiter comprises a plurality of interlocking bend limiter segment secured at an end by an end piece. In alternative, related embodiments a repair system comprises one or more machinable length sections which function as chain clamps to repair a subsea pipeline while the subsea pipeline is still in service and which can comprise interlocking sections similar to bend limiter sections or which are locked in more traditional manners such as by using bolts or other fasteners.
