摘要： A riser assembly and method of installing a riser assembly are disclosed. The riser assembly includes a first attachment element connected to a first portion of flexible pipe and a second attachment element connected to a second portion of flexible pipe. The first attachment element and second attachment element are connected by at least one tether element, via a fixed structure in a configuration such that, in use, in response to movement of the first and second portions of flexible pipe, the tension load at any moment in time, at each attachment element, remains substantially equal.
