Due to the impact of the COVID-19 in the past three years, the crew on board has been unable to handover the jobs face-to-face onboard,especially for some older vessels.The equipment was operated and managed by different crews, the wiring inside the air-conditioning and refrigeration control boxes has been changed too much, which eventually caused the refrigeration and AC system to fail and not work normally. It is too difficult for the crew to check the wiring again according to the electrical diagram,In order to help the shipowner solve this problem, we recommend the replacement of the entire control box. We have successfully implemented this solution on as many as 30 ships at present.
The detail implementation program is as follows:
1.The crew needs to send us the original electrical drawing, and we design the control proposal according to the original drawing;
2.The crew should be provide us the inside dimensions of the original control box;
3.We integrate all electrical components into mounting board, The internal wiring is connected according to the electrical diagram;
4.Power-on and analog test of all functions before delivery;
5.Pack and arrange for the shipment;
6.After receiving the control box on board, the crew only need to connect all the external lines according to the electrical drawing.
7.If there is any problem on site, we can provide remote guidance by video.
Of course, for some control boxes if the internal changes are not very large. only operation display and PLC module on the ship have been discontinued, it is impossible to replace the corresponding spare parts at present. All the discontinued electrical elements must be upgraded. Especially the display screen and PLC module with software must be reprogrammed based on the existing electrical diagram on the ship. We also provide upgrades for all marine air conditioning and refrigeration control systems, Such as York/Novenco/Viking/Sindex etc operating system.
