The paper describes the activities carried out for the modeling and identification of the pipe tensioning system used in the lay of off-shore piping lines. First, the interactions between the components of the tensioning system are discussed. Then, a model of the pipe stiffness based on the catenary formulation is presented. It is valid for S or J-lay, depending on the pipe parameters and on the lay conditions. The tensioner model follows. It is composed by a torque controlled electric servomotor that powers a tracks tensioning system. Finally results obtained in the simulation for different work and disturbance conditions are shown.

Abstract
The paper describes the activities carried out for the modeling and identification of the pipe tensioning system used in the lay of off-shore piping lines. First, the interactions between the components of the tensioning system are discussed. Then, a model of the pipe stiffness based on the catenary formulation is presented. It is valid for S or J-lay, depending on the pipe parameters and on the lay conditions. The tensioner model follows. It is composed by a torque controlled electric servomotor that powers a tracks tensioning system. Finally results obtained in the simulation for different work and disturbance conditions are shown.Pubblicazioni consigliate
