UFF’s ship will be a laboratory for researches at the Center for Studies on Sustainable Systems (CESS/UFF) at Volta Redonda

The Center for Studies on Sustainable Systems (CESS/UFF) coordinated by Prof. doctor Newton Narciso Pereira, assigned to the School of Industrial Metallurgical Engineering of Volta Redonda (EEIMVR), has been active in the development of research related to port maritime sustainability. In this regard, the group has worked in partnership with PECTEN Meio Ambiente in the development of equipment entitled “AUXILIARY SYSTEM FOR CLEANING SHIP SEA BOX AND ADJACENT PIPES”. The purpose of this system is to assist in the cleaning process of ship’s sea chests and adjacent pipes using a sealed device to contain the chemical reagent and biofouling to be generated in the cleaning process, subsequently directing the residues for proper disposal, minimizing the need for divers and interruption of other simultaneous operations.

Basically, the system consists of a device to be attached to the cooling water sea tank inlet to carry out the cleaning by removing deposits and colonies of various biofoulings. The removal of biofouling will take place by a cleaning solution composed of chemical reagent solutions to be injected inside the ship’s sea box by promoting the degradation of biofouling organisms inside the sea box and pipes.

After the reaction time of the solution, the waste from the operation is pumped and directed to a receiving tank and/or waste treatment through a hose, which is also part of the system. The system operates in a closed circuit to avoid the disposal of reagent solution and residues at sea, thus avoiding environmental contamination, release and dissemination of larvae, cysts, eggs, spores or other propagules of organisms, mitigating the problems of spreading, recolonization and proliferation of native and non-native species in the water column and the respective damage caused to the marine, lake and river environment. The coupling and uncoupling operation is carried out with the aid of only one diver, who will also be able to remotely monitor the entire operation, activating the pumps and the flow of fluids inserted in the box. The system’s patent application is being processed by AGIR/UFF. The system will be experimentally tested on the Ciencias do Mar III research vessel.

This development involved the following researchers:

UFF team: Prof. doctor Newton Narciso Pereira, Prof. Dr. Conny Cerai Ferreira, Undergraduate in Mechanical Engineering Andresa Rodrigues de Oliveira.

PECTEN team: Dr. Fernando Moschen, biologist Eric Gabriel and Eng. Fabio Sena.
