About OceanIQ®

Accurately assessing your subsea project and geographical location to provide a complete analysis of the risks, so you can maximise on returns

OceanIQ® delivers industry-leading subsea cable data, route engineering, permitting and consultancy services for telecom and power cable route planning projects, plus ongoing support to maximise the life and efficiency of live systems across the globe.

As part of the Global Marine Group, we have always been at the forefront of subsea innovation – from planning, laying and maintaining cables for the power and telecoms industries, to using our extensive knowledge and data to consult on projects and create world-class solutions in emerging markets.

In 2020, we launched a new business unit built around our wealth of cable data and first-hand knowledge and experience of cable installation and maintenance: this became OceanIQ®.

We have detailed knowledge of 97% of all fibre optic cables laid worldwide, and 70% of power cables, enabling us to deliver accurate assessments for any subsea project across a range of industries. Along with our sister companies, we have prepared for, installed and maintained cables for decades; we know the ocean floor better than virtually anyone else.

In 1850 our predecessors were centre stage in the evolution of what would become the telecoms and internet industry. They overcame extraordinary challenges to connect all corners of the world, through innovation, grit and sheer determination, so that the extraordinary became ordinary. From the Eastern Telegraph Company in the 1800s through to the Global Marine Group of today, our desire to lead innovation remains strong. We continue to deliver first-class solutions to the offshore renewables, oil and gas, and utilities sectors.

Working in partnership has always been at the core of how we work, using our expertise to deliver our customers’ goals. Our offshore and onshore teams, across our business units, are dedicated to building on the foundations of customer relationships and delivering a great service.

Today the Global Marine Group – composed of Global Marine, Global Offshore, CWind, and now OceanIQ® – is full of extremely capable people, sharing a wealth of knowledge and constantly achieving excellence. That passion is evident in the entire team, as together we are committed to engineering a clean and connected future.
