While UNCLOS gave sovereign rights of ownership of certain zones in the oceans to coastal states, to fulfil their socio-political and economic interests in the use of the oceans and its resources, it also provides that it is the indisputable duty of coastal states to manage their claimed portions of the ocean/marine environment and more importantly, protect the environment from pollution, particularly, pollution from oil and gas (O&G) resources. The total quality management approach to safety management views safety programmes and policy implementations as investments and emphasizes that such investments must be able to yield economic returns among others. The aim of the study, therefore, is to determine the economic implications of coastal oil spill induced losses to the Nigerian economy in order to estimate the economic impacts that coastal management programmes of agencies have had. The study adopted the natural resources damage assessment model, using data collected from the Nigerian National Petroleum Corporation (NNPC), the Organization of Petroleum Exporting Country (OPEC) and National Bureau for Statistics (NBS), to determine the oil spill induced revenue losses to Nigeria from 1984 to 2012. It was found among other things that within the period covered in the study, 1984 – 2012, the Nigerian economy lost an estimated 3,928,260,196 naira revenue due to the oil spill. This amount is not inclusive of remediation cost, third party costs and impact on the environment. Proactive use of technology for coastal oil pipeline and drilling platform surveillance was recommended.

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.

(2018 | Port congestion determinants and impacts on logistics and supply chain network of five African ports | This paper typically applied the concept of ranking by inspection using the dwell time of ships in five African ports to evaluate the variations in ship turnaround time and relative efficiency level. This is to identify the active factors that cause port congestion in African ports. The results provided some explanations on the consequences arising from these on notable African logistics and supply chain networks. The findings reveal that the bane of congestion in African ports emanates entirely from either planning, regulation, capacity, efficiency or a combination of these. The regression analysis with IBM SPSS v20 reveals that there is a significant relationship between cargo throughput and other port performance indicators in Nigeria for the study period (2005 - 2014). More so, the t-test reveals that there is a significant relationship between cargo throughput and berth occupancy rate which is significantly indicative of port congestion. This paper, therefore, recommends that African ports should enhance their regulatory mechanisms, and also improve capacity and efficiency level in order to shoulder the ever-increasing challenges of port congestion in years ahead.

The objectives of the study were among other things to determine the empirical probabilities of fatal and non-fatal offshore energy drilling accidents and compare the probabilities for significance indifference. The study used a historical and investigative design method in which time series ocean energy drilling accidents were collected through secondary sources and investigated using scientific and statistical tools including probability theory and independent-sample t-test statistical tools. It was found that though the average empirical probability coefficient of a non-fatal upstream accident over the period covered in the study was higher, there exists no significant difference in the empirical probabilities of fatal and non-fatal offshore energy drilling accidents in Nigeria. Recommendations were proffered based on the research findings. | Berlin, Germany, Journal of Multidisciplinary Engineering Science Studies (JMESS) | ISSN: 2458-925X Vol. 5 Issue 2, February - 2019

| 10 | Nwokedietal (2018) | Comparative Study on Implementation Outcomes of UNCTAD 40-40-20 and cabotage Maritime Policies in Nigeria | tool for planning the development of the maritime transport sub-sector in Nigeria and other nations. Experience in most developing African countries has shown that African nations are not lacking in the development of well-thought-out policy blueprints for the development of her maritime sectors; they rather have poor policy implementation strategies as past records have shown; thus culminating into the failure and total abandonment of well-thought-out maritime development policy plans. An example is the UNCTAD 40-40-20 policy which has helped similar maritime nations like Nigeria to develop adequate capacities in the carriage of their seaborne trade and fleet size but has failed to achieve the same feet in Nigeria. The study was thus carried out to assess the implementation outcomes of the defunct UNCTAD 40-40-20 policy in Nigeria, in comparison with the outcomes of the current cabotage policy being implemented by the Nigeria Maritime Administration and Safety Agency. The historical research design method was used and secondary data were collected and used for the study. The data collected were analyzed using the difference of means model, independent sample t-test and trend analysis. Its result showed a decreasing trend in fleet ownership by Nigeria in both UNCTAD 40-40-20 era and cabotage era. The comparative analysis between the indigenous tonnages in the cabotage and UNCTAD 40-40-20 regimes revealed that the mean tonnages of the indigenous ship owners per annum in the cabotage and UNCTAD 40-40-20 regimes are 229477.2145tons and 279286.3636 respectively over the 11 years period covered in the study. There exists a difference in means of -49809.14909 in favour of the indigenous tonnage in the UNCTAD 40-40-20 regime. These imply similar implementation outcomes in both policies. It was recommended that improvement should be made in the implementation of the current cabotage regime to save it from similar failure like the UNCTAD 40-40-20 regime. | Bangladesh, International Journal of Science and Business | Volume: 2, Issue: 4, Year: 2018 Page: 653-662.

Nwokedi; Buhari, S.O, and Okeke, K.O, (2017) | An Appraisal of Demurrage Policies and Charges of Maritime Operators in Nigerian Seaport Terminals: the Shipping Industry and Economic Implications | This research evaluated the demurrage policies and charges of selected shipping companies and terminal operators in the Lagos ports and the implications in the economy and shipping industry in Nigeria. It adopted the survey approach to gathering data from the dominant container operators (carriers) and the terminal operators. Demurrage duration and categorization of the demurrage periods and charges for each period by the selected operators were collected and compared using the statistical tool of analysis of variance to determine if there are differences among the charges and charging systems. It was found that significant differences do not exist in the average rate of demurrage charges per container per day among the shipping companies and terminal operators in Lagos seaports. The study also found that there is no significant difference in the average amount charged as demurrage among the shipping companies and terminal operators in the three different periods of demurrage duration in Lagos ports, Nigeria. It was recommended among other things that, the Nigerian shippers’ council as the governmental body responsible for freight regulation and protection of shippers’ interest should by policy fix a uniform container demurrage rate for all terminal operators and carriers operating in Nigeria. | International Journal of Maritime Science and Technology | Vol.27 issues 2, 2017

S.(2017) | Critical Assessment Of Maritime Industry In Nigeria: Challenges And Prospects Of Policy Issues. | This Paper reviewed the structural nature, situational contents, abrasive occasional inconsistencies, current challenges and prospects of the Nigerian Maritime industry policy issues. This, over the years, had skewed the development and efficiency of this critical cash-cow industry that firmly holds the beacon of hope and survival of a developing economy like Nigeria. This is because, amongst all the modes of transport, the Maritime industry got the worst hit in terms of poor quality funding, policy inconsistencies and lack of support from the government. This is clear in the non–availability of a functional shipping policy in place to really checkmate the fraudulent sharp practices and vices that usually erupts within the confines of the system. This has in no measure, promoted the pervasive nature of foreign domination of the industry in the carriage of our local generated cargo against the interest of the indigenous stakeholders. Lack of political will to enforce the implementation of some of the initiated government policy in this industry is a strong factor for concern and consideration. This is because, the industry is one that promotes mediocrity and lack of technical and professional expertise, as that is a very key factor for not having a functional shipping policy.

(2018). | Structural changes in the global transport chain: Implications for ports. | Structural changes in trade and transport environment have come about in response to the globalization of production centres, factors and consumption patterns coupled with technological advances in ship and shipping methods. The resulting demand pressure induced on supply chains means that supply chain partners must innovate to remain afloat. On the other hand, ports have been at the receiving end is a critical node in the supply chain. Through content analysis and review of extant literature, the structural changes in the global transport chains were assessed to determine their broad implications on ports. The findings suggest that ports must adopt proactive measures aimed at accommodating strategic interests of shippers and shipping lines/carriers which constitute their major supply chain customers. In line with previous studies, this paper makes a case for the adoption of efficiency measures in ports for sustained viability given the prevailing fluid transport environment. | Journal of Sustainable Development of Transport and Logistics. | Vol.3(1), 22-28.

DOI:10.3390/logistics2010006; | Concerns about performance and efficiency in port terminals led many national governments to embark on port reforms. The Federal government of Nigeria, for example, adopted the Landlord port model which brought about concessioning of port terminals to private operators. Despite high investments in terminal facilities by the private terminal operators, there are still complaints about the level of service offered to port users. This paper applied key performance indicator metrics and parameters of the queuing model in assessing the performance of Nigeria’s concessioned port terminals. Data for the study were obtained from terminal level records of cargo and ship handling activities for years 2000 to 2015. Major findings indicate that cargo and vessel throughputs improved after the reforms in the six ports examined. However, much variability was observed in trends in ships’ turnaround times across all ports after the concession policy implementation. Additional results from the queuing model analysis suggest that the high ships turnaround times observed in some ports are associated with delays in ship operation at the berths. The paper recommends that policy interventions be focused on ship operations at the berths as a step in improving service level in the port terminals. | | |

DOI 10.17265/2159-5879/2018.01.001; | Ports operating in the same geographical range face significant competition among them. In such a setting, less competitive ports may continually lose the patronage of shippers (indigenous to them) to adjacent ones with better attributes. The extent of and determinants of inter-port competition in West Africa’s coast are of interest to port administrators/operators who risk losing a significant portion of their domestic generated cargo traffic to competing for neighbouring ports. In this paper, we explore the question of what port-specific attributes serve as a competitive basis for West Africa’s coastal ports operating in proximity to the other. Through a survey, users of these ports were asked to identify port-specific attributes which they consider when deciding which port to use for shipments making. To enrich our empirical model, data collected from the survey were augmented with secondary data (on the identified attributes) obtained from the respective ports. Statistical evidence from data analysis suggests that ports operating in proximity in the West Africa’s coast compete on the basis of attributes that minimise costs for port users, viz: ships’ pre-berthing time, ship turnround time, crane efficiency and availability of cargo spaces (proxied by frequency of ship calls). Policy implications of the findings were discussed. | | |

DOI 10.17265/2159-5879/2018.01.001 | In this paper, we developed performance assessment criteria to evaluate the effects of compliance to ISPS Code’s requirements on port/terminal operation in Nigeria. The primary data for the study were obtained from copies of survey questionnaires administered to a random sample of port users stratified by areas of specialisation. Hypotheses governing this study were based on the premise that additional port facilities provided and security measures adopted in compliance to ISPS code’s requirements would have positive spillover effects on port operations. Evidence from data analysis indicated that compliance to ISPS code had positive effects on the performance of operational performance of Nigeria ports. Similar effects were also observed in port users’ satisfaction and profitability. The paper contributes by providing a decision support framework for monitoring and gauging outcomes of ISPS code administration in ports and terminals. | | |

The different data types, institutional settings and other socio-economic variables associated with the FCT were articulated as input parameters for the TDR development. It was proposed that as part of design criteria, TDR should incorporate basic elements of road network performance indices, car park asset inventories, rail and BRT travel demand, user specifications, quality management procedures, maintenance standards and goals satisfaction. The TDR Architecture should include the user services, logical and physical components for managing and maintaining an intelligent transport system as well as for providing traffic management and surveillance. The criteria reviewed in this paper highlights relevant needs and provide a decision framework for TDR design and development. It is suggested that implementation of the proposed framework articulated in this paper would facilitate sustainable economic development, regional competitiveness, quality living standards and participative governance of the citizenry in the Capital Territory. | | |
