n pi: special segmented weights attached to the guy wires of a guyed compliant platform that keep the guy wires taut as the platform jacket moves with the waves and current of the water. As tension on a guy wire is lessened, one or more segments of the weight drop to the seafloor and re-establish tension on the wire. As tension increases on a guy wire, the tension pulls one or more segments off the seafloor so that the wire is not over stressed.

n: a compliant offshore drilling platform used to drill development wells. The foundation of the platform is a relatively lightweight jacket on which all equipment is placed. A system of guy wires anchored by clump weights helps secure the jacket to the seafloor and allows it to move with wind and wave forces. See platform rig.
