The Defence Sector

Longitude provides design services, naval architecture, mooring system design and development, vessel structural design, and a range of technical support services to our defence clients.
Our engineering team is highly experienced in the design of military ships for life extension, alteration and amendments. To every defence engineering project, we bring our comprehensive knowledge of ship layout design, equipment design and the design of supporting ships’ steelwork structures, to deliver turnkey work packages.
Longitude Defence projects often feature:

  • Requirements definition

  • Detailed design
  • Structural design
  • Changes to marine engineering systems
  • Detailed drawings
  • Installation instructions
  • Refit specifications
  • Manufacturing support
  • Classification society approvals

All of our defence engineering & design work is well documented at every stage. We work directly with shipyards in the UK and overseas.

Longitude carries out military ship mooring and towing capability assessments both for conventional vessels, alongside berths, and for non-standard operations such as alongside towing-at-sea in waves. We give practical advice on the design and development of mooring systems for new and existing ships, supported as required by the design and analysis of mooring equipment and ship sub-structures. Longitude provides assurance in mooring regulatory compliance, development of operating procedures, and forensic engineering.

Our team is suitably qualified and experienced to develop defence safety cases, and has delivered many multi-stakeholder hazard identification workshops, followed by the generation of endorsed safety case documents.

Longitude is experienced in key military small craft design aspects such as air transportation; air delivery; whole body vibration; autonomous operations; low weight; high speed and robustness for demanding operational roles.

Our clients benefit from our expertise in the design of advanced low-weight composite structures, the assessment of existing structures, lifting structures and structural approvals. Our team has developed and trialled military launch and recovery systems, and has expertise in davit arrangements and docking ships.

Longitude also develops safety management support systems for fleets of craft.
