Abstract: 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.

Abstract translation: 联锁弯曲限制器部分基本上是彼此的镜像，并且通过接合彼此的互锁端部而不使用紧固件而连接以形成互锁的弯曲限制器部分。 互锁弯曲限制器包括多个互锁的弯曲限制器段，端部由端部固定。 替代地，相关实施例中，修理系统包括一个或多个可加工的长度部分，其作为链夹来修复海底管道，同时海底管道仍然在使用中，并且可以包括类似于弯曲限制器部分的互锁部分或被锁定在更多的部分 传统的方式，例如使用螺栓或其他紧固件。
