Marine Cable Group - Case Study

Problem: How To Dry Cables During Deployment

Global Marine Group has a long and proud history in the specialist deployment of subsea cables – inevitably in challenging conditions.

But it needed a drying solution when water on a cable jacket was causing a deployment machine to lose its grip on the cable.

So Global Marine Group called in ACI…

We have extensive experience in cable drying – but Global Marine Group’s requirement was a new challenge for us:

  • The cable diameter ranged from 17 mm to 32 mm (but we usually work with <10 mm cables).
  • The cable can be moving at up to 10,000 metres per hour.
  • The application area is an open deck on a vessel operating in the world’s oceans. This wet environment is much more challenging than a factory on dry land.
  • Seawater is highly corrosive.
  • There are adhesive marker tapes on the cable at prescribed intervals. They must not be removed in the drying process.

And the solution had to be delivered within constrained delivery dates, due to the nature of Global Marine Group’s work. It had to be ready for when the cable deployment vessel was next in port.

Solution: Ring Air Knife

ACI created a ring air knife drying system with a high-pressure side-channel blower.

The ring air knife is hinged so the cable doesn’t need to be threaded through the centre – instead, it is closed around the cable.

We manufactured the equipment from 316L stainless steel, which is highly resistant to corrosion, thanks to its low carbon content and added molybdenum.

Our system included polymer rollers to keep the cable centred within the ring – ensuring that it did not contact the steel edges.

Result: Problem Solved

ACI’s bespoke air knife system was simple but effective (and one of the more unusual cable-drying solutions we’ve created). It works well for the intended requirement.

Global Marine Group said…

“The air dryer has worked particularly well when recovering the cable from the seabed with it positioned in-between the stern sheaves and the linear cable engine.”
