About Longitude

Our Business

Longitude Engineering is dedicated to providing marine design and analysis services to the marine, offshore renewables and oil & gas, defence and small craft market sectors. Our aim is to provide field operators, installation contractors, vessel owners and others involved in the industry with all the maritime engineering assistance they require to ensure their projects are successful.

Our People

We are staffed by naval architects, structural engineers, designers, hydrodynamicists, geotechnical specialists, metocean and coastal engineers, mechanical engineers and marine engineers, all with extensive and broad experience of the offshore renewables and oil & gas, marine, defence and small craft industries gained whilst working in various roles across the maritime industry.

Our Guiding Principles

We consider our most important assets to be our people, our independence and our reputation.

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 are dedicated to helping your marine 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 us unique.
