Reparación del sistema de climatización del barco maria dolores

Company

Electrosur is a company specializing in electrical services and boat maintenance that operates in the ports of Algeciras and Tarifa.

Its projects include the modernization and maintenance of critical systems on passenger and cargo ships.

Challenge

Renovate the air conditioning system on the María Dolores, a passenger ro-ro cargo ship, replacing obsolete compressors that were no longer available, ensuring compatibility with the ship's current systems and guaranteeing reliable operation in a maritime environment.

Problem

The existing air conditioning compressors had serious faults and could not be repaired due to the obsolescence of the variable speed drive and control components.

  • The original system was not compatible with modern equipment.
  • The existing PLC did not allow direct integration with the new compressors.
  • The wiring and control logic had to be completely adapted.
  • It was essential to carry out a safe start-up, validating the system under real operating conditions on the ship.

Solution

How we do it?

Surcontrol took a comprehensive approach to the project:

  • Selection and installation of new air conditioning compressors available in the catalog.
  • Design and installation of a new PLC adapted to the ship's air conditioning system.
  • Complete renovation of electrical and control wiring, complying with naval environment requirements.
  • Programming of the PLC for air conditioning control using new variable speed drives, ensuring stability and efficiency.
  • Execution of the system start-up on board the María Dolores.
  • Performance of functional and safety tests to validate the correct operation of the system in real operation.

Results

  • Fully operational and modernized climate control system.
  • Elimination of dependencies on discontinued components.
  • Greater reliability and control of the ship's air conditioning system.
  • Full integration with new drives and PLCs.
  • Ship ready to operate with a robust and maintainable system in the long term.
