20 Claims

1. A subsea line clamp assembly, comprising a body having an axis and a clamp member, the body comprising at least first and second body segments adapted to be assembled around a subsea line, the body having an anchor attachment point adapted to tether the body to a subsea anchor, the clamp member comprising at least first and second clamp member segments, the clamp member being movable relative to the body and having an outer surface adapted to engage an inner surface of the body, and an inner surface adapted to engage the subsea line within the subsea line clamp assembly, the inner surface of the body having at least one first tapered portion, and the outer surface of the clamp member having at least one second tapered portion arranged to engage the first tapered portion on the inner surface of the body, wherein the clamp member and the body are divided in a direction along the axis into the same number of segments, with each body segment having a respective clamp member segment, and wherein each body segment has a larger angular dimension than its respective clamp member segment, and wherein a first friction value between the inner surface of the body and the outer surface of the clamp member is lower than a second friction value between the inner surface of the clamp member and the outer surface of the subsea line.
