YOUR PROJECT SUCCESS.
Since 2006, Longitude Engineering has delivered specialist design and engineering services in the marine, energy and defence markets. 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 marine engineering and 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 design project succeed. This client-focused perspective, combined with our agile responsiveness and ability to adapt the way we work to suit you, is what makes Longitude unique.
