As part of the Global Marine Group, OceanIQ has always been at the forefront of subsea innovation – from planning, laying and maintaining subsea cables, to using our extensive knowledge and data to consult on projects and create world-class solutions for many market sectors including telecoms, utilities, and offshore renewables.

Detailed knowledge of 97% of all the fibre optic cables laid worldwide, coupled with an extensive understanding of power cables, enables us to deliver accurate assessments for any subsea project. Together with the wider Group, we have installed and maintained cables for decades – this hands-on experience puts OceanIQ (OiQ) in a unique position of knowledge and expertise, enabling us to deliver informed and reliable solutions.

This rich history sees OceanIQ recognised as one of the world’s leading authorities on subsea cable data. Combining our rich data set with route engineering, permitting, and survey services enables OiQ’s customers to prepare for future subsea cable installations, or extend the capability of their existing systems, in addition to facilitating the prevention of unnecessary downtime and maximising cable lifespan.


OceanIQ® offers a range of bespoke services to diverse markets, using our unparalleled experience to maximise installation project efficiency, and reduce long-term risk for any subsea cable project.


Alongside our sister company Global Marine, we have over 170 years’ of experience working in subsea telecommunications – giving us market-leading data and first-hand insight to benefit the effectiveness of your project.


With decades of experience in telecoms, OceanIQ is a natural fit to apply this extensive knowledge to the growing offshore renewables industry. OiQ’s experience transcends the globe, and today we operate in the more established European market, as well as guiding emerging renewables markets around the world – the latter benefiting from our knowledge of the fundamental lessons learnt to date.
