Developing Parametric Modelling for Class 4 Estimate of Pier and Jetty Construction by Analyzing Historical Databases using AI Tools & EVM Techniques.

The growth in energy demand, particularly in the oil & gas sector, influences investment decisions for jetty development to enhance supply capacity. The Dolphin Jetty, a prevalent type used by the National Oil Company, incorporates cylindrical or pile-like structures called dolphins to guide and moor vessels safely. As energy consumption in Indonesia shows a consistent upward trend, optimizing the supply chain and fuel distribution becomes imperative. In this context, maritime transportation, specifically through dolphin jetties, emerges as a strategic choice to efficiently meet fuel distribution needs. This paper emphasizes the importance of preparing Capital Expenditure (CAPEX) documentation in the feasibility studies stage, influencing the economic value of the investment. The paper uses historical data to introduce a parametric modeling approach for Dolphin-configured jetties, considering variations in mooring capacity, dead weight tonnage (DWT), and estimated construction implementation years. The outcomes aim to inform the CAPEX Class 4 preparation, contributing valuable insights for the economic assessment of jetty construction projects. [ABSTRACT FROM AUTHOR]
