Ships
Longitude works with a diverse range of clients, providing through-life support for their barges and ships, to both maintain the given craft and to provide engineering support for the projects in which it is involved.
Ship & Barge Marine Design
Longitude adds value to our clients’ ship and barge projects by being able to draw on a broad range of both technical and operational experience. Our independence means we are always objective and entirely focused on our clients’ needs.
This varied operational experience provides us with a deep understanding of the operational requirements of a given vessel. Our knowledge underpins the decision-making process for all our design projects, from minor upgrades and modifications – through to new-build and conversion projects.

Fit-for-purpose designs
Our ship and barge engineers are highly experienced in risk-based design. With their deep knowledge of the requirements of Classification Societies, they are able to deliver fit-for-purpose designs.
Specifications – from function to construction:
- Design – from concept, basic, through to detailed
