International Women in Engineering Day 2021: Emma Marigi

International Women in Engineering Day



This year we’ll be celebrating the amazing work that women engineers around the world are doing to support lives and livelihoods every day. 



Emma Marigi, from Kenya, is a PhD student in Civil Engineering and a member of the Advanced Materials Testing Centre (AMTeC) group.


My research, which is being conducted in collaboration with the Kenyan Pipeline Company, assesses how flow efficiencies are affected by both deposits and structural deterioration in oil and gas pipelines. It aims to provide a solution on how best to counter these challenges to enhance safety and productivity. 


Oil and gas production are crucial to a country’s economic standing, supporting millions of jobs, providing energy for the population, and fuelling industrial processes.


Research by the International Energy Agency states that how Africa meets the energy needs of a young, fast-growing, and increasingly urban, population is crucial for the continent’s – and the world’s – economic and energy future. By 2025, Africa’s urban population is set to grow by more than half a billion, exceeding that of both India and China. These demographic changes will have profound implications for economic growth, infrastructure development, and, in turn, energy demand.


The United States of America has the largest number of operational and planned oil and gas pipelines, with about 135 functional pipelines compared with 10 in Kenya. Companies in Kenya are incurring multiple billion costs per year through flow inefficiency. My research has the potential to optimise flow efficiency for an effective pipeline integrity management, which will impact the economic development of Kenya and beyond.


Emma's supervisory team is: Dr Jiping Bai (DOS), Dr Paul Davies and Professor John Kinuthia.
