摘要： A flotation assembly for a riser pipe generally includes a pair of elongated semiannular flotation collars fabricated in part of a buoyant material and each including a pair of spaced clamps useful in attaching the collars about the riser pipe. These clamps are preferably imbedded within an inner surface of the collar. The present invention is directed to securing devices for retaining the clamps, and in turn the collars, in place tightly against the riser pipe. These securing devices also hold the choke and kill lines, conventionally associated with a riser pipe, in place adjacent the riser pipe.
