| Abstract | In general, tugboats are used to transport many kinds of unactuated vessels such as ships and offshore structures. This requires an adequate model of tugboats operation to take into account surge, sway, and yaw motions precisely. In this study, we present an optimization method of tugboats operation for transporting an offshore floating crane in shipyard. An optimization problem including the interactions between the crane and tugboats is mathematically formulated. The procedure to solve this problem is composed of two steps. First, the required total thrust force and moment acting on the crane are calculated to make it arrive the target position with desired velocity and direction in the presence of environmental disturbances. Second, the optimization problem is solved by using the genetic algorithms (GA) to find total number of the required tugboats, position, thrust, and direction of each tugboat. The proposed approach is applied to the transportation of the offshore floating crane in the various environmental conditions such as waves, winds, and currents. |
