Estimation of operating profit of liner ship from integrated mathematical model considering design, hydrodynamic performance, and operation

摘要

Traditionally, it has been difficult to evaluate the operating efficiency of ships using objective and credible indicators in order for ship owners and seafarers to confidently plan an optimized transportation strategy considering accurate ship performance. This is due to a number of factors that affect operating performance; the type of ship, cargo, ship speed, sea route, and weather conditions. This paper aimed to estimate the operating profit of a liner LNGC based on a mathematical model developed considering design information, accurate hydrodynamic performance, and operation. Operating profit was assumed to be the expected income minus the CAPEX, OPEX, and VOYEX. The proposed model was used to simulate a voyage from the departing terminal to the arriving terminal to estimate RPM, engine power, electric power, BOG accumulation, BOG combustion, fuel oil and gas consumption, combustion, and operating profit. Finally, the operating profit surface for project life cycle of 25 years including transportation, anchoring at a terminal, and re-docking was reviewed to decide the optimized transportation strategy.
