Patent ID: 8721222

Claim:
A rolling assembly for installation on a subsea conduit, the assembly comprising: a. At least two rolling module elements attachable to one another to form a rolling module having a cylindrical outer cross-sectional shape having two ends and defining an internal cavity for receiving a subsea conduit such that when installed on the subsea conduit the rolling module is rotatable with respect to the subsea conduit, wherein the rolling module is in direct contact with the seabed and wherein rotation of the rolling module over the seabed facilitates lateral movement of the subsea conduit; and b. A pair of clamp units installed on the subsea conduit proximate each end of the rolling module, each clamp unit comprising: i. A pair of semi-cylindrical clamp elements attachable to one another to form each clamp unit having a cylindrical outer cross-sectional shape and having a clamp interior surface for surrounding and contacting the subsea conduit such that when installed on the subsea conduit each clamp unit is fixed circumferentially and axially with respect to the subsea conduit; such that the rolling module is fixed axially with respect to the subsea conduit.
