    Effects of maritime logistics on port efficiency in Nigeria
    (Federal University of Technology, Owerri, 2024-03) Nnaukwu, Charles
    The study analyzed the effects of maritime logistics on port efficiency in Nigeria. It used the Lagos Apapa port and Eastern port of Onne to investigate the effects of maritime logistics performance on port efficiency in Nigeria. The ex-post facto research design was used in which secondary data on the ship turnaround time, waiting time, time at berth and cargo dwell time prevailing in Lagos Apapa port and Onne port each year between 2007 and 2019 was obtained and used as proxies for maritime logistics performance and the cargo throughput performance and ship call handled by the port was used as indicators of productivity. The time expended per annum in port operations measured in man-hours and the average time vessels spent at berth annually in the ports between 2007 and 2019 were obtained and used as input to estimate the efficiency of the port in cargo handling relative to expended efforts in man-hours, the efficiency of the port in handling ship calls and the berth efficiency of the port. The augmented efficiency model was used to estimate the efficiency of the port as described above while the log-linear multiple regression analysis was used to estimate the effects of maritime logistics performance on the cargo handling efficiency, ship output efficiency and berth efficiency of the seaport. The test of hypotheses reveals that in all cases, there is a significant effect of maritime logistics performance on each of cargo handling/throughput efficiency, ship output efficiency and berth efficiency in both ports. The models showing the relationships and effects of maritime logistics on the various components of port efficiency in Onne are shown: In EFFICARPUT = 1.366 - 0.072InSHTRTIME + 0.081InCARGODWELLTIME + 0.014InWAITINGTIME -0.16InBERTHTIME + e; In EFFISHTR = 0.007+ 0.109InSHTRTIME - 0.001InCARGODWELLTIME + 0.001InWAITINGTIME + 0.003InBERTHTIME + e; and In BERTHEFFICIENCY = 1.103+ 1.667InSHTRTIME + 0.193InCARGODWELLTIME + 0.264InWAITINGTIME - 5.706InBERTHTIME + e. For Lagos Apapa port, In BERTHEFFICIENCY = 23.320 + 0.252InSHTRTIME + 0.072InCARGODWELLTIME - 0.041InWAITINGTIME - 8.535InBERTHTIME + e; In EFFISHTR = 0.698+ 0.27InSHTRTIME + 0.031InCARGODWELLTIME -0.004InWAITINGTIME - 0.025InBERTHTIME + e. It was recommended among other things that, port authorities and terminal operators must implement maritime logistics strategies to improve the maritime logistics performance indicators and subsequently improve port efficiency.
