Ensuring subsea fibre optic cables remain operational with repair and maintenance services during the COVID-19 pandemic has been essential for keeping the power on and internet services connected.

Global Marine Group's (GMG) Global Marine use a number of sophisticated Remotely Operated Vehicles (ROV) that can be submerged thousands of metres underwater and are capable of locating and carefully handling cables that are millimetres in diameter off the seabed, ensuring that there is no further damage.

Once the issue has been identified and a solution determined, Global Marine can use the ROV to pull the cable onto the ship, where repairs can then be carried out with limited downtime.

While internet consumption has spiked during the pandemic lockdown, industrial and commercial energy demand has reduced significantly.

Consequently, the main threat that COVID-19 poses is a shortage of engineers that could lead to power disruption. This means it is critical that faults that occur outside of the mainland are quickly and effectively resolved, a task that GMG's Global Offshore is committed to.

Global Offshore’s Complete Cable Care solution offering pre-engineered options means that cables on the seabed get fast and effective maintenance should any unplanned repairs be required. This significantly reduces the risk of power shortages and minimises disruption for energy developers and operators.

GMG's CWind plays a key role in power generation infrastructure, providing logistics and personnel for essential maintenance of offshore wind farms throughout the UK.

CWind teams are working in tandem with other units of GMG to provide inspections, subsea surveys, and temporary power, to ensure that wind farm output remains effective throughout the year.
