“…Moreover, they did not consider the hydrostatic effects and the hydrodynamic effects on the floating crane but rather assumed that the wave-induced motion is sinusoidal. [1][2][3][4] In our research, the floating crane lifts the heavy load; the load is located in front of the floating crane, which causes the pitching motion. Moreover, the ratio of the length L to the breadth B of the floating crane is 2.39, whereas the ratio L/B for other types of ship is approximately 5.0-6.0.…”

“…Therefore, these methods do not constitute an affordable control system for the floating crane. [1][2][3] Parker et al 4 presented the load swing control of the ship-mounted rotary crane, using a tagline system, and incorporated the interactions between the crane and the cable-payload assembly in the mathematical model. However, the hydrostatic and hydrodynamic forces were not considered.…”

This paper presents a tagline proportional-derivative control method for suppressing the swing motion of a heavy load suspended by a floating crane in an ocean environment. The tagline mechanism, which is connected between the floating crane and the heavy load, is applied to the floating crane. The winch, which is mounted on the deck of the floating crane, is used to control the tension of the tagline. A proportional-derivative control algorithm is applied to generate the control force of the winch. Swing angle feedback of the proportional-derivative control is supplied by the encoder attached at the boom tip of the floating crane. To demonstrate the performance of the tagline control method, numerical simulations are performed on a non-linear six-dimensional mathematical model of the floating crane and the heavy load. The mathematical model of the floating crane is constructed to consider both the three-degree-of-freedom principle of the floating crane and the heavy load, based on multi-body system dynamics. The numerical and experimental simulation results are compared using a one-hundredth-scale model of the floating crane in the model basin. The results of the numerical simulation and experiment show that the tagline proportional-derivative control method suppresses the swing motion of the load.

“…Another mechanical anti-sway system is Rider Block Tagline System (RBTS) which is much simpler than Maryland Rigging in both control and structure, but it will be limited when the rope is too long. Parker designed an active rider block tagline system (ARBTS) [4] and compared it with Pendulation Control System [5] , it was found that using ARBTS control strategy the payload could be maintained in a fixed inertial position using 80% less power compared to using the slew, luff, and hoist strategy alone.…”
