Ship energy conservation projects

There are sound economic and environmental reasons for demand control of HVAC. Making sure we use the energy only where it is really needed is the basis for this. As an example a large restaurant is often kept over-ventilated during its off-hours, just to make sure it’s not becoming too hot when suddenly used. Tremendous amounts of energy can be saved by just tuning the automation system to respond quickly enough to the sudden increase in load, and trusting that, we can keep the ventilation at a minimum during off-hours. Clever software algorithms encapsulate this functionality, and a simple interface is shown to the user. A typical project contains the following:

• Onboard survey
• Suggestion of modification and time planning
• Hardware design, modification of drawings
• Software design
• Installation of Frequency Converters and other necessary products
• Dismantling of old – Installation of new control system components
• Commissioning & handover
• Scheduled follow-up visit
• Training

We carry out this as a turn-key or as part delivery in accordance with requirements of each project. Most of our systems are actually commissioned during ships normal operation, so dry-dock time is not necessary.
