Sener has converted a ship that in origin offered fish-farming services, into a workboat to give oil, water, cargo and antipollution services complying with MARPOL. The barge, El Faralló Dos, was originally designed and built to offer aquafarming services, for the transport of alevins and fishes between the fish-farm cages and the port. This transport was carried out by means of four holds in the midship. The barge was fitted with all the machinery and services to carry out the fish operations and the ice production.
