Abstract
Novel repair-and-support ships can conduct spot systemic maintenance and repair (MR) working for damaged offshore platforms on a remote ocean. This causes competition against shipyards when repair-and-support ships enter the MR market of offshore platforms. Therefore, to wisely decide the optimal strategy for repair-and-support ships, competition analysis is conducted between the repair-and-support ship and shipyard when providing MR services for damaged offshore platforms on a remote ocean from the three aspects of space, time and cost. A pricing game model of the repair-and-support ship and shipyard under multiple repair tasks on a remote ocean is formulated, considering the choice preference of repair decision-makers and the characteristics of the repair-and-support ship as a compound player. Aiming at the particularities of this model, a solution method based on an iterative algorithm is designed to address the pricing game model. It is proven that the designed solution method has advantages in global optimality and CPU running time by comparing it with an enumeration method. In the numerical part, we obtain the optimal pricing strategy and management insights into the technical gaps and damage degree of offshore platforms. The results can provide theoretical and decision support for the pricing strategy of repair-and-support ships entering the MR market of offshore platforms.
