It was found that the vessel suffered from overall low HVAC performance which was due to the PLC malfunctioning, causing system unable to perform due to electronic based.
The provided solution was that we will be able to resolve PLC malfunction error as well as refurbished and retrofitted for both Main AC system through overhauling.
The issue that we are dealing with bad room cooling and low packaged units performance.
Issues were rectified in a shipyard with the need of scaffolding to get to the concerned area.
All operations could be accomplished without delay and our client was satisfied with the new optimized performance of his HVAC system.
It was found that HVAC System 2 compressor and condenser was causing low HVAC performance. Units suffered from extensive operating hours and overhauling services is highly recommended.
A major operation of such scale is usually done in shipyards. However, with our special techniques and processes, the operations was completed in the port as 2 jobs and completed within 2 calls.

This case study is about poor HVAC performance and it’s resolved by our Riding Crew in Australia.
As we all know that a HVAC system has many parts and equipment to make up a whole system. Suction valves, pipes anf flanges are not excluded in this case as well.
Suction and stop valves were changed with adequate ones and flushing of the system was also done to remove all contaminant deposits that have formed in the unit. As part of our working process and in order to ensure a long lasting optimal performance, filter cores were renewed and several hours of leakage tests were conducted.
All works has been conducted by our Riding Crew in 2 different locations in Australia.
Evaporator leakage and cannot be identified?
Cooling deficiency?
After running through an inspection and following our 5 Steps Formulation, the AHU’s evaporator coil was showing signs of fatigue. There are also internal leakages which could not be seen from outside were also identified.
Solution proposed was to install a new coil which was customized fabrication according to the ship requirements. Most importantly, The installation process was completed within 24 hours.

Are you experiencing unknown low cooling efficiency?
Similar to the previous case study on HVAC issues and how resolved the issue of low cooling efficiency.
As per our 5 steps flow set up, we first have identified the problem, shared our findings and solution: Overhauling of the main AC as well as HVAC maintenance program for SMC106s, CMO28 & 26 Compressors were proposed. After close inspection, our engineers’ troubleshooting solution was also to overhaul the main AC while multiple spare parts were required for replacement.
Are you experiencing Low AHU system running on low cooling efficiency?
This is a case study of how we identified the vessel’s HVAC issues and resolved the issue of low cooling efficiency. The vessel was anchored at Tuas Megayard, Singapore for the service rendering.
As per our 5 steps flow set up, we first identified the problem; the old unit reached an advanced stage of corrosion, especially the coils and the blower. Contaminants were also found in the system. The solution is to install and replace the ship’s AHU as the old unit is malfunctioning due to wear and tear.
