Reinforced cable solutions for underwater tunnelling

NOVACAVI recently applied its full capability for design and manufacture of custom-built cables for harsh environments providing special supply and power communication cables for the construction of a new underwater tunnel.

Cables had to be engineered and expertly produced considering they have to perform as a link between surface vessel and sub-tube junction unit at 100m depth.

Often retracted and released by the winch on the deck of a tugboat, these high performant cables dive into the water and occasionally touch the ground during the extreme construction process.

On basis of these severe operational requirements, NOVACAVI conceived and supplied a longitudinal water tightness cable solution with overall braided stainless-steel wire reinforcement for longitudinal cutting prevention and an external close wave polyethylene monofilament over braid for additional protection to rely on throughout the underwater tunnel project.
