Abstract
A marine riser system, a buoyancy system, and a method of buoying a body. A riser joint includes a body, a buoyancy module, a thrust collar, and a reaction collar. The buoyancy module is coupled around the body and configured to produce a buoyant force when submerged at a subsea location. The thrust collar is coupled around the body and engaged with the buoyancy module to transfer the buoyant force to the body. The reaction collar is engaged with the body such that movement of the buoyancy module is restricted by the reaction collar.
