Recent activities in the oil and gas industry have shown an increasing need for monitoring engagements, such as in shipping, logistics, exploration, drilling, or production. Hence, there is a need to have asset management of these offshore assets (or facilities). Much of the offshore infrastructure is currently approaching or past its operational life expectancy. The study presents an overview on asset management of offshore facilities towards monitoring, safe practices, maintenance, and sustainability. This study outlines the major considerations and the steps to take when evaluating asset life extensions for an aging offshore structure (or asset). The design and construction of offshore structures require some materials that are used to make the structural units, such as offshore platform rigs, ships, and boats. Maintaining existing assets in the field and developing new platforms that are capable of extracting future oil and gas resources are the two key issues facing the offshore sector. This paper also discusses fault diagnosis using sensors in the offshore facilities. The ocean environment is constantly corrosive, and the production activities demand extremely high levels of safety and reliability. Due to the limited space and remote location of most offshore operations, producing cost-effective, efficient, and long-lasting equipment necessitates a high level of competence. This paper presents the guidelines on asset monitoring, sustainable maintenance, and safety practices for offshore structures. In this study, the management of offshore structures were also presented with some discussions on fault monitoring using sensors. It also proposes sustainable asset management approaches as guidelines that are advised, with policy implications.

Environmental valuation (EV) research has advanced significantly as a method of assigning value to environmental goods, many of which lack readily discernible market values. The term “environmental valuation” describes a number of methods for putting monetary values on environmental effects, particularly non-market effects. Over the years, there has been a continuous increase in the number of publications on the topic. According to searches via the Scopus and Web of Science (WoS) databases, the phrase “environmental valuation” first occurred in 1987. The current research examines patterns in publishing rates over the previous three decades to analyse environmental valuation activity. To identify the future pathway, a research pattern was identified using Scopus, WoS, and the Altmetric Explorer. The data were postprocessed using VOSviewer to identify the mapping networks; then, Voyant Tools were used to explore the keywords. A summary of the demand for environmental valuation is also provided based on the literature review. However, the findings of this historical analysis indicate that despite the academic efforts on this subject, environmental valuation is not used in research as much as one may anticipate. In addition, the study gives a general outline of the future directions that environmental valuation research is anticipated to follow in light of the current academic research initiatives as well as academic market and policy market research efforts. The study shows that the United Kingdom (UK) showed the highest publications by location in this field. Additionally, the study shows that the choice experiment approach is preferred over the contingent valuation method, and this work illustrates this preference. It also demonstrates that only a small number of papers have had a significant influence on the researchers in this field.

Sustainability has been advocated in the housing sector in developing nations but its adoption is hampered with myriads of barriers. This study investigates the critical impediments to sustainable housing delivery. To achieve this, 18 commonly used barriers in existing literature were selected for investigation in this study. Structured questionnaires were administered to 91 housing developers within metropolitan Lagos, Nigeria and analyzed using both weighted mean and factor analysis. The ranking and normalization analysis showed that out of these investigated barriers, deficiency in government motivations for sustainable housing, non-existence of sustainability enforcement and the absence of information on the sustainable building technologies database were the topmost three critical challenges to sustainable housing delivery. The factor analysis also showed that the underlying factor groupings of the critical barriers can be classified into technology and cost, knowledge and awareness, policy implementation, client and economic related barriers. These research findings have added to the sustainable housing literature within the context of Nigeria. They also create a reliable blueprint which would assist all stakeholders in taking the sustainable approach to ameliorate these impediments, thus promoting sustainability attainment in housing delivery.

The ground can become saturated during prolonged downpours. If sewers and drains are unable to cope, overflows will be inevitable. This situation could affect properties that are not designed to cope with flood hazards. It is pertinent that property investors should consider flooding and the likelihood of its occurrence when making investment decisions. The question is, “do they?” This study investigates the factors that influence residential property investment decisions in flood-risk areas of the Lagos metropolis. This is achieved by evaluating a range of locational, neighbourhood, structural, market/economic, behavioural, and risk characteristics in the determination of residential property investment choices in areas that are susceptible to flood risk. The data were sourced from private investors and registered real estate agents in the risk areas of Lagos State, Nigeria. Structured questionnaires were used for data collection purposes, and only valid responses were used for the data analysis. The results show that the availability of infrastructural supply, the crime rate in the neighbourhood, and the property location could significantly motivate investors’ decisions with respect to property investment in flood-risk areas. The perception plot shows that behavioural factors have the highest bearing on the investment decisions for private investors, at 4.4, followed by economic factors at 4.0 and locational factors at 3.6. The plot also shows that neighbourhood factors have the highest bearing on the investment decisions for estate agents, at 4.6, followed by economic factors at 4.0 and locational factors at 3.6. This implies that there are various degrees of correlation between the factors examined in this study. It is important to highlight the relevance of the findings for the field and pave the way for future scientific development in flood-risk management.

This paper evaluates how households consider environmental attributes alongside other housing attributes in their residential location decisions along the coastline in Victoria Island, Nigeria. The data were obtained from tenants’ revealed preference surveys where 204 respondents rated 15 identified and most common key factors in the order by which they influence their residential location choices. The factor analytical approach was then applied to understand how these factors influence such decisions. Thus, this study also gives bearing to the factors considered in making policy and/or investment decisions around residential location choice (RLC). The results revealed the presence of four key components with a total variance of 70.76%. Among the components, neighbourhood, critical dwelling cum socio-economic attributes are found to have a significant influence in explaining 39.78% of the variation in the factors influencing the study area’s selection as the residential location choice (RLC) for households. The findings have implications for households’ residential location choices. For residential locations to be equally attractive to tenants, policymakers and urban planners should pay attention to addressing the menace of the neighbourhoods including crime and traffic congestion. Moreover, property owners should respond to tenants’ needs by paying attention to the provision of utility facilities such as portable water and an appropriate mix of toilet/bathrooms to available bedrooms.

Digital disruption in real estate transactions has led to the full adoption of digital marketing in real estate agency services. However, the demand for su
