Replacement of variable speed drives and adaptation of PLC in naval air conditioning for Electrosur
Company
Electrosur is a company specializing in electrical services and boat maintenance that operates in the ports of Algeciras and Tarifa.
In one of its projects, they faced a critical failure in a ship's air conditioning system, specifically in one of its main compressors.
Challenge
Replace a faulty and discontinued frequency converter with a modern model, adapting the entire electrical installation and control system to ensure the proper functioning of the boat's air conditioning.
Problem
- Obsolete and discontinued drive: The original equipment could not be repaired or directly replaced with an equivalent model.
- Technical incompatibility: The new drive required modifications to wiring, signals, and control logic.
- Critical system for the vessel: Air conditioning is essential for the boat's operability and habitability.
-
Need for safe start-up: It was essential to ensure stable operation after the system adaptation.
Solution
How we do it?
We carried out comprehensive engineering and automation work to adapt the existing system.
- Electrical engineering: We redesigned plans and modified the wiring to integrate the new frequency converter.
- PLC adaptation: We updated the PLC control logic to correctly manage air conditioning with the new drives.
- Complete integration: We adjusted signals, protections, and communications to ensure compatibility and reliability.
- Commissioning: We performed functional tests and validated the correct operation of the system under real operating conditions.
Results
- Fully operational ship air conditioning system with new variable speed drives.
- Extended service life of the installation without the need to replace the entire system.
- Stable and efficient operation of climate control via PLC.
- Successful adaptation of an old installation to current technology.
-
Reduction in downtime and improvement in the operational reliability of the vessel.
