 Abstract
An experimental study on a subsea installation using an offshore crane was conducted. Concrete blocks, suction piles, and manifolds were considered in this study. Free decay tests were conducted to investigate the fluid characteristics of the subsea structures. The added masses of the structures were estimated. The motion response amplitudes of the subsea structures were compared for different structures and water depths. In addition, the dynamic tension transfer function of the crane wire was investigated. The root mean square values of the heave motion and the dynamic amplification factor of the wire tension were investigated in irregular waves.
