Opis:: This paper assessed the trend of productivity of the existing six Nigerian ports. Secondary data was extracted from National Bureau of Statistics (NBS) Annual Reports, Nigeria Port Authority (NPA) Annual Reports, and Central Bank of Nigeria (CBN) Annual reports. Using the Data Envelopment Analysis technique, it was discovered that Calabar Port had been under-utilized towards the achievement of the required results. On the contrary, Rivers Port requires technical touches in her operations. As a liquid bulk port, the time of loading and discharging of commodities are often more than any other type of port and the turnaround time at this port are often more. Scale optimization is also required in Rivers Port. Inferentially, Lagos Port has been operating on optimal scale size but fluctuating managerial efficiency was experienced in the operation years. As a matter of findings, Tin Can Island has a similar trend to that of Onne Port with low productivities in the pre-concession period which improved consistently in the post-concession year of 2010 till the year 2015. It was also observed that Tin Can Island Port operated on under-utilization of inputs resources in the pre-concession periods till the post-concession year 2010. This reflects the element of wastefulness concerning both inputs and outputs quantities. Delta Port experienced fluctuating scale and technical efficiency trends in both pre and post concession years. Hence, it is observed that productivities' trends vary among the concessioned Nigerian Ports. These could be as a result of the influence of varied exogenous and endogenous factors on individual Port.

Opis:: The study adopted ex post facto design. Using ship traffic, vehicle traffic, berth efficiency, turnaround time as input explanatory variables and output factors as average throughput to compare the pre concession and post concession. The six Nigerian ports: Tincan Island Ports, Apapa Port, Port of Delta Warri, Calabar Port, Rivers Port and Onne Port were sampled. It is observed that year 2014 is the most efficient year out of the 36 operation years in terms of output maximization with constant levels of inputs under the study period with score 1.0 respectively serving as 32 times benchmark for other years. It is observed from that Tin Can Island Port was technically efficient in the operation years of 1980, 1981, 1985, 1995, 1997, 1998, 2009, 2013, 2014 and 2015 with score 1.0. However, the most efficient operation years are 1998 and 2013 while the most inefficient year is with efficiency score 1.0. The post-concession years that the port was technically inefficient are 2006, 2007, 2008, 2010, 2011 and 2012.

Opis:: The obsolesce and decay of rail transport infrastructure linking major seaports Cities to hinterland cargo origin and destination centers serviced via the seaports and the total lack of rail infrastructure connection between some hub seaports and the hinterland cargo centers in Nigeria induces enormous economic setback. Most rail routes from seaports to the inland container depots (ICDs) in all the geopolitical zones of the Country are currently inoperable. Government’s recent attempt to develop and make operable the rail routes is faced with funding challenges necessitating the need for a Public Private Partnership (PPP) approach in which government provides regulation and enablement while private sector operators fund the projects. This study was aimed at providing economic justification for private sector investment in developing, revitalizing and making operable, the rail-freight-corridors between hub-seaports and inland container depots in Nigeria. It estimated the operator-benefits and profitability potentials of investment in each of the ten rail-freight-corridors consisting of existing but inoperable and proposed rail routes from Lagos, Port-Harcourt/Onne, Warri and Calabar seaports to the Inland container depots in different geopolitical regions of Nigeria. Secondary data on the import and export (cargo generation) capacities of each of the ICD regions to and from the respectively connected hub-seaport were obtained from the Nigerian ports authority statistical report covering a period of two years (2018-2019) based upon which the annual expected revenue earnings of the operators (investment) were estimated as a product of the total annual TEU handled by each route and the price of delivering per TEU from the seaport to the ICD region. The cost of investment in developing and operating each rail-freight-corridor as determined in previous studies for the Nigerian Shippers Council for the same period were also obtained. Benefit-Cost-Ratio (BCR) and Net Present Value (NPV) tools were used to estimate the operator-benefits and profitability potentials of each rail route within the period using 10% interest rate. It was found that six of the rail routes have BCR > 1; and NPV > 0; implying higher operator-benefits over costs within the period. The rail-routes from Lagos seaport to Gombe and Bauchi; Warri seaport to Aba; and Calabar seaport to Kano have BCR < 1; and NPV < 0; implying higher operator-costs over benefits and unprofitability of the routes within the first two years of service delivery. It was recommended that the PPP terms for rail freight corridors with BCR < 1 and NPV < 0, should have a higher contract period than the other routes to enable the private investor have a higher payback period to recoup the cost of investment and earn profit.

Opis:: In highly competitive shipping market environment, container network operators-Freight forwarders, shipping companies etc. are concerned about design, development and deployment of optimized allocation model to achieve cost savings through improved container storage yard operations, crane productivity, outbound container allocation/distribution to seaport terminals and hence reduction in ships’ waiting times. In this paper, we developed two models, the Dynamic programming model and optimal allocation policy (model), for the optimal allocation of units of outbound laden cargo containers of sizes: 20ft and 40ft to six (6) major seaports in Nigeria. The distributions of the laden containers were allocated as follows: Port-Harcourt, Tincan Island, Onne, and Calabar seaports were allocated with 1,064 units of stuffed containers each. Apapa seaport was allocated with 2,128 units of laden containers, and zero allocation was made to Warri seaport. These results were arrived at through the implementation of the optimal allocation policy. The zero units allocation made to Warri seaport could be attributed to poor shipper patronage and hence the low frequency of ship visits. Apapa seaport was allocated double the number of containers moved to the remaining ports because it attracted more shipper patronage and hence more ship visits. Hence, freight forwarding companies will be assured of cargo spaces and make more profit by allocating more containers. Policy implications of the developed models were discussed.
