Abstract

An increased study into improving ship energy management has been prompted by worldwide worries about the high cost of bunker fuel. The study present both empirical and analytical approaches considered in predicting the vessel fuel consumption and the hull resistance of a chemical tanker vessel on a voyage from Escavos, Delta to Lagos port (Apapa) in Nigeria enroute Lome port (Togo) and Tiko port (Cameroon). The speed and route of a ship must be determined by balancing numerous objectives such as cost, arrival time, and cargo safety. DMarine Book, a computer model that employs the Holtrop technique to calculate vessel power and resistance power was designed to estimate the degree of energy efficiency by the deployment of energy efficient technologies. The semi empirical model was used in the development of C shape code for simulating energy efficiency. The approach was used to develop the model for predicting the vessel resistance, EEOI for a given fuel consumption hence reducing the overall emission level of the vessel as part of the implementation of ship energy efficiency management plan (SEEMP). The built software (DMarine Book) can be used as a decision tool for operators of the chemical Tanker vessel onboard. Under calm weather conditions, operating the chemical tanker vessel at a speed of 12.18 knots (economical speed) rather than a speed of 14.5 knots (rated speed) resulted in a reduction in vessel resistance of about 159.17kn and decrease in fuel consumption. The results are considered consistent with those of other authors who employed various models and similar operating conditions and came to similar conclusions. When running a vessel at an economically efficient speed, the Energy Efficiency Operational Indicator (EEOI) calculation shows a decrease in EEOI and Carbon Dioxide (CO₂) emission.
