ABOUT

Zero Emission Electric Tugboat

ZEETUG represents the new generation green and high technology by being re-chargeable and all electric with zero emission and no noise. This innovative design allows the vessels to operate powerful with higher efficiency in line with not harming the environment.
 

With the aid of the modular system ZEETUG can be custom build from 5T BP up to 80T BP.
 

ZEETUG is also a smart harbor tugboat; a power efficient electric tugboat, capable of managing its
energy and reach on longer distances.

POWERFUL

For tugboats with very high requirements in terms of speed and performance or a widely varying demand for power, ZEETUG full electric propulsion system is capable to deliver the high-power output.

 

The full electric propulsion system offers the flexibility of being able to maneuver very precisely, and a powerful bollard pull!

Meantime, compared to diesel tugs, ZEETUG responds to commands much faster!

SMART

STEMS (Smart Tug Energy Management System) software is developed by NAVTEK NAVAL TECHNOLOGIES with the objective of optimizing the electric power consumption of the electric watercraft and extending its driving range and operation cycles. STEMS always in charge to manage the fleet of ZEETUGs.

EFFICIENT

ZEETUG is a more efficient technology comparing to the combustion engines. During the combustion, only 30% of the energy is generated to mechanical power, while the significant portion of the energy is wasted to the environment as a heat... This amount is 80% with ZEETUG. An electric motor also has more torque starting up and high-power output than an internal combustion engine.

ENVIRONMENT FRIENDLY

ZEETUG30 is expected to reduce CO2 emissions by 210 tons and NOX emissions by 9 tons a year. This value in emission reduction is equivalent to saving about 580 trees according to carbon meter calculations!

SAFE

The batteries located in the fore and aft battery room keeps a constant temperature through a cooling system. This cooling system provides an optimum temperature for the battery safety conditions. Another feature: ISU is designed to not starting up before the charging plug is connected properly!

BUDGET
FRIENDLY

85% lower operating costs of full-electric propulsion systems is also a real benefit for the operators. Further, the high-power output means a significant increase in comfort levels! No noise, no vibration, no emission! Just efficient operation!

IN LINE WITH NOT HARMING THE ENVIRONMENT

STEMS

SMART TUG ENERGY MANAGEMENT SYSTEM

Developed by NAVTEK Naval Technologies Inc., with the objective of optimizing the electric power consumption, extending ZEETUG’s operational range and battery lifetime.

 

The first application of STEMS has been performed on GİSAŞ POWER (ZEETUG30) @2019. Which is the first zero emission, re-chargeable and full electric tugboat in the world.

 

STEMS is both a browser-based and a mobile software, which has a lot of capabilities for fleet control center and tugboat operators. With its flexible structure, it can be adapted to a fleet.

 

STEMS collects all data coming from the devices and equipment in the tugboat and stores them in the Control Center’s server. It uses the related data to performance, to optimize the electric power… 

 

  • Tug speed, 

  • Motor speed, 

  • Power consumption, 

  • Battery motor temperature, 

  • Battery state of charge, 

  • Actual ambient condition’s data, 

  • Weather data, 

  • Route 

  • The position and the other facts (speed draft) of the ship that shall be assisted 

  • Charging station occupation
     

ADVANTAGES

 

  • STEMS can be used on more than one ZEETUG® (a whole fleet) 

  • Towage operations can be scheduled on considering the availability of the charged (ready to operate) ZEETUG®. 

  • The final charge of batteries can be estimated. 

  • Both the control center operator and the tugboat operator can change predefined route on chart. 

  • Any type of Android mobile tablet (personnel or industrial type) can be used. 

  • All data coming from the ZEETUG® are being stored in the control center servers. 

  • STEMS can prepare reports of all operational output. 

  • Due to the possible operation profile changes the software can be revised.

 

FEATURES

 

  • A single platform to control the entire ZEETUG® fleet. 

  • Integration with Marine Traffic charts. 

  • Collecting data coming from all devices and equipment of the electric tugboats and storing them in the server. 

  • Displaying real-time wind data from ground stations 

  • Monitoring all relevant data related to performance of the tugboats and giving feedbacks. 

  • Charging time estimation by considering the battery’ state of health 

  • Reporting tools for operation and personnel performance 

  • Ready for online diagnostic & maintenance
     

 

QCS

Quick Charge Station (QCS)

The Quick Charge Station is designed (tailor-made) for ZEETUG® by NAVTEK NAVAL TECHNOLOGIES INC.

 

Charging ZEETUG is an easy process! You simply plug ZEETUG® into a charger that is connected to the Quick Charge Station.

 

The time it takes to charge a ZEETUG® varies based on the charger you use like other electrical devices. We adjust the technical characteristics of ZEETUG® according to the existing operational profile and needs/requirements of our clients.

 

LESS THAN 1 HOUR 

Quick Charge Station can charge a ZEETUG30 in less than 1 hour.

1,25 MVA

It supplies 2 ISU (IGBT supply unit) with 500 V Ac voltage provided from 1,25 MVA transformer.

500 KW

By charging this AC voltage coming from the IGBT supply units, DC 780 V is converted to the charging stations 2 output line cables and 500 KW nominal charging power is taken from the charging line.

BELOW 80%

The Quick Charge Station delivers the energy rapidly, the STEMS software automatically alerts you when the charging is completed! Charging above 80% is not typically necessary.
