  • Here is one of the Ile de Batz's two main cable tanks, with a small amount of spare 17mm cable included for the benefit of those touring the ship.

    Each of the ship's two cable tanks can hold up to 5,500km, or 3,000 tonnes, of fibre-optic cable. There are also two spare tanks, each with a 250-tonne capacity.

  • This is the linear cable engine used to feed cable from the tanks to the rear of the Isle de Batz, from where it descends to the briny depths.

  • This massive and surreal device is the Isle de Batz's plough, which is used to bury cable.

    The cable can be buried up to 3m under the sea bed, which happens in waters up to 1.5km deep. This is the limit of what those in the industry consider to be 'shallow' waters — areas where fishing takes place, and cables need to be especially well protected.
