Environmentally Friendly

The Envirocart™ will enable the entire hull to be cleaned in water, the other alternatives that TT-Line have trialed only allow us to go a meter below the waterline.

The other major advantage of the Envirocart™ is that it removes, filters and contains the biofouling whilst treating the water prior to discharge making it environmentally friendly.
