Item Open Access Econometric modeling of the impacts of shipping on Nigeria economy(Open Access International e-Journal, 2016-01) Nwokedi, T. C.; Okoroji, L. I; Igboanusi, C. C.The study is conducted to establish a quantitative relationship (model) between the impacts shipping on the economy of Nigeria and the Gross Domestic Product (GDP) using an econometric method and to test the significance of the impact. The econometric/analytical method of regression analysis was adopted to achieve the objective. Time series data of 10 years were collected on the past contributions of maritime transport to the national output (GDP) from the Central Bank of Nigeria annual statistical bulletin. Hypotheses were tested using t-test. The test showed the rejection of null hypothesis HA and the acceptance of null hypothesis HB to conclude that maritime transport has made significant impact on the Nigerian economy over the period covered by the study.Item Open Access Cabotage implementation in Nigeria: Analysis for improving coastal shipping business opportunities for local and joint venture operators(Exclusive Journal Publishing House, 2016-01) Nwokedi, Theophilus C.; Igboanusi, Chinemerem CThe year 2013 marked a decade of the implementation of cabotage law in Nigeria. This study analyzed the implementation of the policy over the 10 years period from 2004 to 2013. The aim of the study is to assess how the implementation of the policy has affected indigenous and foreign coastal shipping firms and how to use the policy to increase coastal shipping business opportunities for local ship operators. Data on number of cabotage vessels chartered from local and foreign shipping operators, their charter fees for each year covered the study were obtained. Assuming equal charter rate for cabotage vessels of local and foreign operators chartered in each year covered by the study, the research estimated the earned by each class of operator from charter fees. The difference of means statistical method was used to analyze the data on number of local and foreign ship operators vessels charter over the period and revenue earned from cabotage vessel. T-test was used to test each null hypothesis. Both null hypotheses H0A and H0B were rejected for the alternate hypotheses. The research found that Non-Nigerian (foreign) ship operators have earned more revenue and supplied more vessels to coastal shipping operations in Nigeria. It was recommended that the cabotage policy be amended remove the provision for waiver option to foreign vessel and encourage joint venture arrangement between local and foreign firms.Item Open Access International trade flow analysis using the gravity model - The Nigerian conondrum(MNK Publications, 2014) Onyemachi, Chinedum; Igboanusi, Chinemerem C.; Ezenwa, Anthony Ekenehe work surveyed several international trade flow models applied to transportation and spatial interaction analysis. The connectivity between international trade flow, port development and hinterland acquisition were analyzed based on evolving market demands.The relevance of the gravity model both to the international trade and port hinterland analysis were identified. Methods for the estimation of trade flows using natural logarithms applied to the gravity model were developed. Furthermore, the work assessed the rising influence of both hub and dry ports in the world of international trade. While the later is situated in the hinterland, the former is situated at few major world ports. The relevance of the gravity model in determining the location of these port types was emphasized. The strategic roles of rising hub ports to world trade were also discussed. Relevant data were picked from the Nigerian Import and Export environment.Item Open Access A safety culture improvement model for West Africa’s offshore sector(Science Publishing Group, 2016-12-29) Onyemechi, Chinedum; Sule, Abiodun; Nnadi, Kenneth. U.; Igboanusi, ChinemeremAbstract: The work analyzed safety paradigms presently being applied in the solution of West Africa’s security and safety problems and proffered solutions based on improved safety culture principles. In the study the safety orientation attributes of offshore vessel operators in West Africa were measured with a view to improving safety in offshore support vessels, Floating, Production, Storage and Operations (FPSO) vessels operating in the region. The contributions of safety orientation to the greening of the blue economy were also analyzed. Also analyzed in the work were accident rates in the sub region in recent times. The work suggested methods for improving operating safety climate in West Africa’s maritime domain. The contributions of continuous learning as well as other safety paradigms were analyzed with a view to reducing accident rates inthe sector.
