The investigation of life cycle costs of Mobile Harbour Crane: a case study in Berlian Terminal at Tanjung Perak Seaport Surabaya

Cost is one of the important components that may not be separated in loading and unloading operations, as tariff setting of terminal operation depends on the level of cycle costs implemented. During the life cycle, from the planning to operational stages, every stage is closely related to the cost component. If it is not well managed, it may consequently generate higher costs in the loading and unloading operation. The equipment focused of this research is Mobile Harbor Cranes (MHC) which are being operated in Berlian Terminal, Tanjung Perak port, Surabaya. The main problem as a main concern of this research is how to correlate the allocation of cargo handling equipment with the cost planning during the lifetime of the equipment. Particularly to clearly define the level of costs expended in accordance with the time and workload of the equipment. The research aims of this research, therefore, is to evaluate and optimize the cost cycle value of MHC based on its energy usage applying linear programming. As the result, the research finds that MHC maintenance cost were higher than operational cost. To achieve more efficient maintenance and operational costs, 11 scenarios of energy usage were applied to have a balance life cycle cost arrangement
