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.

Purpose This paper aims to investigate construction site workers’ compliance with various coronavirus (Covid-19) protocols while working on construction sites. Design/methodology/approach This survey was conducted at the end of the imposed lockdown following Nigeria’s upsurge of the Covid-19 pandemic. The survey research method was adopted for the study using a structured questionnaire administered to 246 construction site workers under strict Covid-19 preventive measures. The data was complemented through personal observations of the study site activities. The results were analysed using frequency tables and a factor analytical approach. Findings The preventive measures in place on construction sites can be classified into personal protective measures, good etiquette/manners, contact precautions and prompt actions. Although the workers claimed to be aware of the Covid-19 pandemic, their disposition towards the preventive measures on construction sites is worrisome. Hence, their level of compliance with the protocols could mitigate the spread of the virus. Originality/value This paper fulfils an identified gap to study the need to promote public health by mitigating the global pandemic’s spread in areas where social distancing cannot be easily observed.

The impairment of interests due to oil spill damage necessitates valuation for compensation purpose. However, the question of adequacy of the compensation offered to victims of oil spillage in Niger Delta Region (NDR), Nigeria remained unanswered after decades of oil exploration and pollution in the region. The paper examined the disparity between the expected and actual monetary compensation paid to claimants for their impaired interests. A multistage sampling method was applied and data were randomly collected from residents of five oil producing communities in the region using questionnaire. In all, 1,940 questionnaires were administered but 1,125 (57.99 %) were found suitable for the analysis. The data collected were analyzed descriptively and inferentially. The results of Kruskal Wallis test showed a significant difference in the residents' description of compensation adequacy across the selected communities; Chi-Square (χ2) = 33.221, p-value = 0.000. The result of T-test indicated that there is significant difference between the expected and actual compensation paid based on the current practice in the each of the selected communities in NDR. The paper recommended that as much as the cleanup

This paper examines the role played by valuers in choosing the right viability appraisal technique for an investment appraisal. Structured questionnaire was administered on Twenty one (21) registered and practicing Estate Surveying and Valuation firms in Akure out of which fourteen (14) were retrieved and found good for analysis. The data obtained were analyzed using descriptive statistical tools such as frequency tables and weighted mean score 3 and 4-point likert formats. The result of the analysis revealed that Valuers mostly make use of Payback Period, NPV and IRR, which are deterministic in nature. This is as a result of the valuers basing their appraisals mostly on economic and financial criteria only without fully analyzing the various factors such as the prevailing inflation rate in the economy and the level of risk tolerance of their client. The outcome of a good investment appraisal forms the basis upon which any investment decision is based. A good investment is an offset of a good viability appraisal, and the valuers' role is to give such advice that will maximize the benefit's objective of the investor.

Purpose Building information modelling (BIM) is a novel technological advancement in the built environment. Despite the potentials of BIM, its adoption and implementation are undermined in facility management (FM) operations. This might be because of limited information on the critical success factors (CSFs) that can enhance its adoption. The study aims to integrate building information modelling to improve facility management operation by adopting fuzzy synthetic approach for evaluating the critical success factors. Design/methodology/approach Data for the study were sourced from practising and registered facility managers within Lagos metropolis, Nigeria. The data collected were analysed using a combination of methods which include mean item score, factor analysis and fuzzy synthetic evaluation (FSE). Findings The factor analysis results showed that six underlying groups of CSFs would enhance the effective adoption of BIM in facility operations. The FSE results showed that out of the six groups, the three topmost important CSF grouping (CSFG) in the decision rule would enhance the effectiveness of BIM adoption for FM operations. Practical implications The result of this study provides a credible road map for facility managers, policymakers and other stakeholders in FM operations on the CSFs and CSFG required for the adoption of BIM. Originality/value Previous studies that aimed at integrating BIM into FM are limited. Hence, this study provides a broad perspective on the CSF required for BIM adoption and implementation in FM operations using the FSE approach.
