Offshore EPCI Project Expert Engineers & PhD

IZURDEA OFFSHORE CONSULTING is an independent offshore engineering company built around one core expertise: the full lifecycle support of EPCI projects, from early-stage feasibility to execution at sea.

Built on extensive experience in large-scale offshore infrastructure projects, our team provides the technical depth and practical field experience required to ensure reliable offshore EPCI project delivery.

We offer advanced technical and managerial expertise across maritime operations, heavy lifting systems, safety, design and installation engineering of Power Cables, Umbilicals, Flexibles, Risers and Subsea Structures, and the associated technologies & equipments.

Beyond EPCI project execution, IZURDEA OFFSHORE CONSULTING is deeply engaged in multidisciplinary R&D initiatives, bridging academia and industry to develop practical, innovative solutions supporting a more sustainable Blue Economy.

Power Transmission & Submarine Cables

From conductor wire to vessel deck, our team has developed its expertise across the full offshore cable value chain — working for manufacturers, installers, TSOs, wind farm developers, and technology providers. We address every aspect of a cable project, whether it involves dynamic HVAC cables for offshore floating wind or static inter-array, export, and HVDC interconnection cables: component physics, system design, marine operations, and economic drivers. R&D programme management is also part of our track record.
