Submarine Cables Experience

Amplitude is a trusted advisor in the field of submarine power cables, offering end-to-end consulting services for both AC and HVDC systems. With a strong foundation in engineering and project delivery, Amplitude supports clients across the full lifecycle of submarine cable projects—from feasibility and concept design through to installation, operation, maintenance, and repair. Their approach is grounded in technical rigour, practical insight, and a deep understanding of marine environments.

In the early stages of development, Amplitude provides concept design and cost estimation services that are tailored to each project’s unique requirements. Their capabilities include the design and rating of polymer, mass impregnated, HVDC, and AC MV/HV/EHV cables. Using advanced software modelling, they simulate various environmental and installation scenarios to optimise performance and reliability. Accurate cost estimation for cable manufacturing, transport, and installation ensures clients can plan with clarity and confidence.

To safeguard long-term cable integrity, Amplitude conducts detailed Cable Burial Risk Assessments (CBRA) during the route planning phase. These assessments combine qualitative seabed analysis with quantitative evaluations of marine activities such as fishing, shipping, and dredging. Anchor strike probability and Mean Time Between Failures (MTBF) calculations inform recommendations for burial depth and protection measures, helping to mitigate risks and extend asset life.

Amplitude also plays a key role in submarine installation planning, supporting the execution of cable deployment campaigns with precision and care. Their testing and fault management services include factory and field testing specifications, fault detection and pinpointing techniques, and equipment specification for fault investigation. In the event of a fault, Amplitude’s cable readiness and repair planning ensures rapid and effective response, covering everything from spare parts strategy to post-repair testing and root cause analysis.

Beyond core services, Amplitude offers a suite of specialised consulting capabilities that add value throughout the project. These include technical specification development, owner’s engineer services, cable factory auditing, and coordination of submarine surveys. With a proactive and collaborative approach, Amplitude empowers clients to achieve reliable, cost-effective, and technically sound outcomes in their submarine cable projects.
