HVAC is an important system for cruise ships. In marine environments, safe and healthy conditions are regulated with respect to temperature and humidity and quality of air. TMS installed thousands of Frequency Drivers for AC Ventilation to optimize and keep the public area cool and save energy and fuel.

TMS installed numerous variable frequency drives across the Holland America fleet’s HVAC systems. The use of variable frequency drives on HVAC optimizes energy use and saves fuel.


The Engine Room Ventilation is a point of reference for create an environment ventilated and balanced, our system consist to apply the frequency driver at all fans relative the engine room, and other technical space where the operators and the devices are need to recharge the air. All rooms are locally controlled by the pressure meter and thermometer sensors, and in some case we will measure the quality air too. Our system is called ERVES (Engine Room Ventilation Energy Saving) All information is collected in a monitoring system, and the other signals will be integrated with the existing ship automation. The monitoring system helps the operators to understand which is the state of the unit, the trend and the health of the entire system, a friendly graphic interface follows all operations suitable on demand.

TMS installed our ERV (engine room ventilation) system, including a user-friendly interface and variable frequency drives on several Holland America vessels. Our system monitors pressure, temperature and quality to maintain optimum air conditions.


Holland America

OCES (Onboard Cooling Energy Saving) systems have been installed by TMS on several Holland America vessels. Our system utilizes chilled water and variable frequency drives to monitor the pressure and temperature of HVAC system. Operators can then control the use of fuel much more effectively.

OCES (Onboard Cooling Energy Saving) as a TMS application, consists of the control of the chilly water flow in base to calculate the request on the HVAC stations (Heating Ventilation & Air Conditioning) spread in all zone of the ship.

With the installation of an appropriate drive on the chiller pumps, and an adequate monitoring control on pipes as pressure and temperature of the source connected at an PLC (Process Loop Control) we have a result of increasing energy saving and reducing mechanical wearing on the equipment. The complete system its figured on on HMI (Human Interface Machine) system to help the operator to carry out all needed action.

Holland America Weather Station

TMS installed a weather station onboard Holland America vessel to collect data for potential fuel savings. Data is shared via the vessel’s automation system.

Fuel Savings

TMS can design, engineer and install two versions of fuel savings systems: Onboard Cooling Energy Savings based on HVAC usage and engine room ventilation. Both systems are integrated into your vessels automation and monitoring.
