VIRTUAL TOUR

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.

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.
