“…Factors influencing CF have long been categorised into mechanical, metallurgical, and environmental (Wei and Speidel 1972). Some mechanical factors include peak stress (Zhao et al 2017), cyclic frequency, stress ratio, load waveform (Adedipe et al 2016;Igwemezie and Mehmanparast 2020), residual stress (RS) ; metallurgical factors like alloy composition, microstructure (Nicolas et al 2019), wielding defects, heat treatment (Mehmanparast et al 2017); environmental factors like pH (Kolawole et al 2019), temperature (Atkinson and Chen 1993), electrochemical potential (Kovalov et al 2018), inhibitors (Lindley and Rudd 2001). Material and environmental factors including temperature and pH seem to have a direct impact on pitting CF.…”

Digital tools such as machine learning and the digital twins are emerging in asset management of offshore wind structures to address their structural integrity and cost challenges due to manual inspections and remote sites of offshore wind farms. The corrosive offshore environments and salt-water effects further increase the risk of fatigue failures in offshore wind turbines. This paper presents a review of corrosion fatigue research in horizontal-axis offshore wind turbines (HAOWT) support structures, including the current trends in using digital tools that address the current state of asset integrity monitoring. Based on the conducted review, it has been found that digital twins incorporating finite element analysis, material characterisation and modelling, machine learning using artificial neural networks, data analytics, and internet of things (IoT) using smart sensor technologies, can be enablers for tackling the challenges in corrosion fatigue (CF) assessment of offshore wind turbines in shallow and deep waters.

In today’s world, there is increasing demand of new technologies. As the world is growing, new technologies are emerging. To sustain the new technologies, technologies used for its maintenance must be developed. In the aviation industry with respect to the Industry 4.0 system, its maintenance strategies are also developing. The aim to this study is to present a mathematical model which is used to predict the ageing of any technical system. The authors used the Markov process theory to model the ageing process. As per the model, results and future work are determined and discussed briefly.

“…In view of this, their objective was to evaluate the investment case for the Nigerian power sector in light of developments in the operation of the new regime and core issues that have unfolded since the private investors took over. Kolawole et al [27] presented reliability and power loss analysis, using case study of a power plant in Nigeria. In this study, an assessment of the reliability of a power generating plant was carried out to provide an opportunity to checkmate frequent fault occurrence and prolonged outages.…”

Electricity is one of the most important invention of Man. It powers the economy and everything in a Nation. This work seeks to carryout a critical review of Nigeria’s energy crisis. A PricewaterhouseCoopers, PwC reports asserts that Nigeria still ranks 2nd worst in the global electricity access charts; a significant portion of electricity is generated from private generators at a higher cost of NGN 120/kWh while grid-based cost NGN 4-5/kWh; more than 50% Nigerians do not have access to electricity, however amongst the other 50% who have access, experience intermittent power supply; 5 - 6 times increase in electricity consumption required to match peer countries with similar GDP per capital; 25 % of potential energy reaches the end-user: Structural inefficiencies across the power value chain prevent electricity from reaching end-users. This work sets out to chronicle Nigeria’s energy crisis: its challenges and prospects. Results from various reviews show that the major issue plaguing the nation’s electricity sector isn’t so much about resources, which the Nation has in abundance, albeit, some in potential state. From the reviews so far, the following are the major problems: 1. The National question 2. Lack of technical know-how 3. Sabotage of government’s efforts and destruction of power sector physical assets. 4. Inconsistency in Policy formulation and implementation. The work therefore, proposes that for the long run, the nation tries to solve her national question; however, for the short run, the Federal Government should adopt the NLNG business model that has produced fantastic results for all its shareholders and stakeholders. The researchers therefore strongly advice the Federal Government to adopt the business model of the Nigeria Liquified Natural Gas, NLNG Company.
