    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.
