The Engineering Consultants. Driving sustainability in energy and oceans. Since 2006, Longitude Engineering has delivered specialist design, engineering and analysis services to support renewables, maritime, and oil & gas sector. Our independence, expertise and experience make us the natural choice for a wide range of design solutions across Asia Pacific, Europe and North America. We take a holistic view of design from the overall concept through to the smallest detail: rather than simply focusing on a craft or platform, we’re dedicated to helping your marine project succeed. We combine this client-focused perspective with agile responsiveness, and our ability to adapt the way we work to suit you. It’s what makes us unique. Longitude specialises in vessel design, refit and conversion, pre-FEED and FEED services, marine operations engineering, and engineering solutions for energy transition technologies. Longitude is part of the leading independent global consultancy in energy and oceans, ABL Group. Our work is rooted in our purpose to drive sustainability in energy and oceans, and underpinned by our values: Safety, Technical Excellence, Collaboration, Innovation and Truth.
