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.

National Oil Company Mooring Profile

Tanker is crucial in distributing refined fuel to end customers throughout Indonesia. The fuel distribution in Indonesia, with its more than 17,000 islands, relies heavily on tanker transportation as its primary mode of transportation. Consequently, facilities such as jetties play a significant role in the supply and distribution chain, where the continual improvement and construction of jetties are undertaken to enhance the reliability of the supply across Indonesia. The growth in energy demand, especially in oil & gas, significantly influences the investment decisions for Jetty development to enhance supply capacity and coverage days.

According to the Oil final consumption by-product data for Indonesia from 1990 to 2021[1], the energy consumption in Indonesia shows an upward trend each year.

Furthermore, the jetties owned by the National Oil Company have a considerably long construction lifespan. The data on the Percentage of Mooring Facilities of Various Ages is evident, where the dominance of jetties with ages exceeding 30 years.[2] Consequently, the need for Jetty Development becomes a frequent investment activity to enhance infrastructure reliability and ensure supply security.
