    (David Publishing, 2017) Onyemechi, Chinedum; Nwokedi, Theophilus Chinonyerem; Okeke, Okechukwu; Igboanusi, Chinemerem; Chikwendu, David
    The reassessment of ocean economy contribution of nations has become a new strategy for frontier states adjacent to the coastal region for the improvement of their position in the efficiency frontier curve. The continuity of a coastal state to remain a leader in the production and efficiency frontier curve of modern day development will thus depend on their ability to sustainably develop their most strategic economic resource base such as the ocean economy. The major economic bases include sustainable fishing, offshore oil field developments, offshore biodiversity development and marine biotechnology, offshore mining of manganese nodules, offshore wind farm potentials, international shipping (marine transport) and adjoining corridor development, ship dry docking potentials, marine renewable energy as well as other potentials outlined in the definition of African Union strategy for the development of her blue economy. Adopting the regression analysis and analysis of variance analytical tools, the study found that about 90% association exist between the GDP (gross domestic product) of the West African state (Nigeria) and her GDP. It equally found that offshore oil and gas energy sector more significantly impact on the GDP of Nigeria than other ocean economy business clusters. Given the various contributing marine environment business cluster used in the work, the model depicting the influence of the ocean economy of Nigeria is: Y = 2295334779895 − 29473X1 + 3436995749 − 5927686X2 + e.

    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, Chinemerem
    Abstract: 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.

    Assessment of simulator adaptability in West African Maritime Institutes: A data envelopment analytical approach
    (Juniper publishers, 2017-06-28) Onyemechi, Chinedum; Abiodun, Sule; Igboanusi, Chinemerem
    The work analyzed the role of simulators and technical laboratories in influencing curriculum development strategies of West Africa’s maritime educational sector. The application of IMO’s STCW requirements on simulator based education were also analyzed in juxtaposition with the educational programmes in the higher education maritime programmes of West African institutions. Development knowledge gaps were identified and recommendations made accordingly. The gains of implementing a port simulator training programme for the region’s expanding port sector were emphasized. The focus of the work remains creation of officers with shorter sea time exposure during training.

    Benchmarking study of West Africa’s offshore support ship building and repair capability
    (Juniper, 2020-09-28) Onyemechi, Chinedum; Igboanusi, Chinemerem; Ezenwa, Anthony; Sule, Abiodun
    The work surveyed current position of most West African Ship building outfits through a benchmark study of the building and repair capabilities of these yards vis a’ vis the offshore ocean oil and gas production sub sector and posed a great need for massive investments derived from well-established methods like, diamond model. Recommended solutions include immediate revitalization of research on the subject areas of Ocean technology and Naval Architecture. Pathways for quick realization of this objective were based on the evolution of a new industry to academic model that draws from local content experience of advanced countries ocean technology ecosystem. An analysis of Nigeria’s shipbuilding drive was made using existing facilities in her shipyard sector. Application of assembly line system and the modular methods were analyzed to determine best techniques given existing facilities in the region. Benchmark study of the entire sector was made evolving new policy directions for the region’s rich oil sector.

    Challenges of multimodalism in the West Africa’s trade corridor
    (U. P., 2020-09-07) Onyemechi, Chinedum; Sule, Abiodun; Igboanusi, Chinemerem; Ezenwa, Anthony
    The work surveys the intermodal improvement models applied in modern times to improve port supply chain systems for world’s busiest ports and assesses how West African ports especially the overtly congested port of Lagos can benefit from these improvement models. Different aspects of the port operations drivers were considered including the land side, the sea side and digital technology business ecosystem. An assessment of developmental pursuits of Nigeria’s central government for the port sub sector was analyzed and criticized. The findings shows that a system of development that fails to consider logistics and supply chain improvement models will achieve limited development. The work hitherto assessed Nigeria’s freight and passenger transport development models and found absence of linkage between the various modes, thus the proposal of an intermodal development option that links the road the rail and barge transportation alternative. The focus of the work not only proposes methods or the reactivation of the functionality of the Niger river presently dredged but unutilized, but goes ahead to design an intermodal alternative incorporating both road and rail transport alternatives. International best practices of countries already applying this model were applied. A model was built from the work based on multinomial logit model explaining the dependence of cargo throughput on two other variables drawn from Nigerias’ economy namely consumer price index and gross domestic product. An exponential increase was found in the variable gross domestic product based on multinomial logit model. The West African economy of Nigeria was advised to go multimodal based on the findings.

    Port service quality study of Nigerian sea ports
    (David Publishing, 2017) Onyemechi, Chinedum; Amanze, Azubuike Chibuzo; Igboanusi, Chinemerem; Sule, Abiodun
    This study is focused on service quality assessment in the Nigerian ports with Western and Eastern port zones as study areas. It discovered the level of satisfaction derived by port users by evaluating expectations and perceptions at the ports using some selected analysis tools to test raised hypothesis. This evaluation was based on the service quality model as developed by Parasuraman within the core dimensions of Empathy, Responsiveness, Tangibles, Reliability and Assurance. The attributes of expectations and perceptions raised within these dimensions were addressed with two hypotheses. H1 (Hypothesis one) and H2 (Hypothesis two) were addressed with the results of Factor Analysis which identified the significance port users attach to service quality dimensions and their respective attributes.

    Sustainable transport development options for Nigerian lakes
    (Ijournals, 2014) Onyemechi, Chinedum; Igboanusi, Chinemerem C.; Ezenwa, Anthony Ekene
    The work assessed development options in general and transport development options in particular, open to governments and states surrounding lakes. The methodology applied in the study includes random sampling through interviews of major companies in the region. For lakes situated in a desert environment the sustainable development pathway would be the avoidance and prevention of desertification through policies that favour lake expansivity. Processes that favour the expansivity of lake volume through dredging and channeling of rivers to the lake environment should be sought. The work suggested that installation of boundaries or moles to prevent building of sand dunes by lake boundaries be applied where possible. States utilizing such lakes should develop sustainable development policies to be applied in the process of utilizing the marine resources existing in the lakes. In the area ofrenewable resources like fishes, the commodity should be designed to be harvested to an optimum sustainable level. For non-renewable resources, like under water minerals the number of contractors accepted into the region should be limited to an optimum sustainable level approved by the states concerned. Other lakes not suffering from desertification as well as all lakes should be made to adopt the new environment standards of the oceans that emphasize prevention of oil spills such as MARPOL 73/78 (International Convention on Marine Pollution Prevention from Ships 1973 and the protocol thereto 1978) etc. Furthermore, the renewable energy resources of the lakes where it is made open to interested firms should be made to be tapped in a sustainable manner. Major Nigerian lakes such as the Oguta lake of Nigeria, Lake Chad situated between Nigeria, Niger and Cameron were made the major focus of this study. Sustainable transportation strategies necessary for the future development of these lakes were identified and recommended.
