Project Benefit:

Hydrofix provided project management and technical support for the Q&E Submarine Cable Project, delivering onshore and offshore survey management across both North and South routes. Our technical survey managers coordinated multiple survey disciplines including geophysical, hydrographic, UXO, and geotechnical campaigns.

Through integrated survey management and route design services, we optimised cable corridor selection and developed feasible installation pathways. Our UXO survey coordination and risk assessment protocols ensured safe operations while our design feasibility studies supported decision making throughout the project lifecycle.

The project demonstrates Hydrofix’s capability to manage complex multi-route submarine cable projects, coordinating diverse survey requirements while maintaining technical standards and project schedules.
