Staff profile

Bayan Mohammad is a Chartered Civil Engineer and a committee member of the Offshore Engineering Society within the Institution of Civil Engineers. He has extensive experience in structural and offshore engineering, having worked on a wide range of offshore construction and marine engineering projects involving the installation and decommissioning of oil and gas infrastructure as well as offshore wind structures across the North Sea and the Middle East.

Following graduation, Bayan began his career with HMC, where he worked as a structural engineer supporting offshore installation and decommissioning activities. His work involved structural assessments, lifting analysis, and engineering calculations for offshore construction operations and heavy lifting activities.

After three years in this role, Bayan joined Red7Marine, where he progressed to the role of Principal Engineer. During this time, he supported and led projects across structural and geotechnical engineering as well as marine operations, contributing to the planning and execution of offshore and nearshore works using floating structures as well as jack-up barges.

• The rapid expansion of offshore wind energy has led to the widespread installation of large-diameter monopile foundations. While significant research has focused on installation and in-service performance, comparatively limited attention has been given to the theoretical and practical feasibility of removing these foundations at the end of a wind farm’s operational life. Demonstrating whether proposed removal methods can be practically implemented offshore remains a key challenge, and this area of research remains relatively novel with limited studies worldwide.
• The substantial costs associated with large-scale numerical modelling, experimental investigations, and offshore field trials have also limited progress in this area. Although many offshore wind farms are approaching the end of their operational lifetime, current guidance often follows legacy practices from the oil and gas industry, where foundations may be cut below seabed level and left in place.
• My research investigates the feasibility of offshore monopile removal by examining potential extraction techniques through isolated mechanisms and combinations of methods, aiming to support safer and more practical decommissioning strategies for offshore wind infrastructure. This work utilises advanced finite element analysis to simulate large-deformation behaviour during monopile extraction. Different soil constitutive models are implemented to better capture soil–structure interaction and to assess how varying soil conditions influence the effectiveness of proposed removal approaches.
