Dynamic interaction of a guyed tower with its guying system
One of the key aspects of designing a guyed tower is the selection of a guying system that can adequately resist the anticipated environmental forces. Fundamental to this design is the inclusion of dynamic forces on the guylines and the interaction of these forces with the motions of the guyed tower structure. This paper discusses the analysis procedure and results of the guyline dynamics study for the Lena guyed tower (Mississippi Canyon 280-A). This structure, which represents the first commercial application of this new platform concept, is scheduled to be installed in 1,000 feet (305 m) of water in the Gulf of Mexico in 1983. The paper begins by reviewing the main elements of the guying system and describing the functional requirements for the various components. The main thrust of the paper is to describe the nature of the force-displacement behavior for the guying system and to discuss the implications this behavior has on the dynamic interaction of the structure and guying system. Because the dynamic motions of the tower and guylines interact, it is necessary to couple these two systems to predict the response of both systems accurately. This paper discusses both systems and the procedure used to calculate the response of this coupled system, and presents results of the analysis performed for the Lena guyed tower.
