Abstract
There is disclosed a system comprising a substantially cylindrical element, at least one strake element about a circumference of the cylindrical element, wherein at least one of the strake elements are closed and comprise a thickness measured in a direction along a longitudinal axis of the cylindrical element less than two times an outside diameter of the cylindrical element, and wherein the strake elements operate to reduce the vibration of the cylindrical element when the cylindrical element is subjected to a fluid current.
Claims22
A system, comprising:
- a substantially cylindrical element;
- at least one strake element about a circumference of the cylindrical element;
- wherein at least one of the strake elements are closed and comprise a thickness measured in a direction along a longitudinal axis of the cylindrical element less than two times an outside diameter of the cylindrical element;
- and
- wherein the strake elements operate to reduce the vibration of the cylindrical element when the cylindrical element is subjected to a fluid current.
A method of reducing vibration in a cylindrical element, comprising in any order:
- mounting at least one closed strake element about a circumference of a substantially cylindrical element, wherein the strake element comprises a thickness less than two times an outside diameter of the cylindrical element and operates to reduce the vibration of the cylindrical element when the cylindrical element is subjected to a fluid current;
- and
- installing the substantially cylindrical element in the fluid current.
