The Effect of Ship Docking Variable Configuration on Ferry Docking Time

One of the strategy models in maintaining the financial performance company that operates Ferry Ro-Ro is through increasing revenue and optimizing company expenses by creating cost efficiency. Maintenance cost especially ship docking cost is the second-largest company expense because to meet with regulatory requirements for all passenger ships such as Ferry Ro- Ro must be conducting docking work every year. Efficiency docking costs can be conducted by decreasing ship docking time thus decreasing ship docking cost and also could increase ship availability days to deliver operational excellence and maintain customer service levels. Optimizing ship docking time could be conducted by analyzing variable influence to ship docking time. The goal of this study is to discover factor characteristics that influence work time of docking work for ships by considering management perspective through questionnaires from Indonesia’s largest Ferry Ro-Ro company. Management assessment also aims to conduct weighting of variables then analyzed with Analytic Network Process (ANP) methods using Superdecision software. The result shows five priority variables that influence on docking time of Ferry Ro-Ro such as the age of the ship variable, the ship length variable, the steelwork variable, the work of engine variable, the propulsion work variable based on management perspective. Furthermore, the priority variables used to build variable configurations variation models by combining one variable with another variable until formed 25 configuration variable variation models. The variable configuration variation model was tested using sample data from 72 Ferry Ro-Ro ships owned by PT. ASDP Indonesia Ferry (Persero) with linear regression and multiple linear methods using Minitab software that aims to get the combination of variables that most affect on docking time of Ferry Ro-Ro ships. The analysis result shows that Ship Docking Variable Configuration (SDVC) models with configurations consisting such as the age of the ship variable, the ship length variable, the steelwork variable, the work of engine variable, the propulsion work variable have become the most influential configuration variables on ship docking time with a level of significance of 71,30%. The outcomes of the configuration variable identification could become management consideration for implementing planned maintenance management which aims to reduce the amount of work that must be done at the time of ship docking by optimizing docking work before ship conducting docking without affecting the ship’s operating day especially on steelwork, overhaul work & propeller work for a ship that has old age and has long dimension. Planned maintenance implementation, especially on steelwork, engine overhaul work, propeller work on older ships with large dimensions can make the company create plan material and labor needs at an optimal cost and also make long term relationships with suppliers thus could increase management opportunities to achieve economies of scale in the ship maintenance supply chain process. This result is also expected can enrich the literature on ship docking management and contribute to Ferry Ro-Ro company to minimize potential delays in docking time then could increase ship operating days thus increasing the company revenue and corporate performance.
