​WRTB / VRTB TURBINE vertical wind turbine

WRTB: Next-Generation Proven Wind Tech. 

Maritime Integration.

Retrofitted or built-in as a propulsion supplement (e.g., rotor sails, rigid wing sails). Installed as a power source (e.g., for "cold ironing" at port, hybrid power plants).

(Concept offer) Vertical Axis Wind Turbine (VAWT):

A Key Enabler for Green Electric Ships.
The Vertical Axis Wind Turbine (VAWT) "Classified as a power generation asset (not WASP)" offers a compelling solution for advancing sustainable maritime transport. Unlike traditional wind propulsion systems, an onboard VAWT can generate clean electricity continuously—24 hours a day, whether the vessel is stationary or underway.
This capability provides a consistent auxiliary power source, reducing reliance on fossil-fueled generators and enhancing overall energy efficiency. By integrating VAWT technology, the shipping industry can take a significant step toward true emission-free operations, making green electric vessels more viable and autonomous.
In short: VAWT WRTB technology offers solution, around-the-clock renewable power generation at sea, positioning it as a critical component for the future of electric shipping.

The Passive Power of Uncompromised Resilience

VERTICAL AXIS WIND TURBINE WRTB-MARINE-5 kW (25 kW concept)

​Wind Turbine Technology (for electricity)

Converts wind kinetic energy into electrical power.

Wind → Mechanical Rotation → Generator → Electricity → Onboard grid/storage.

Generate electricity for onboard or onshore use (hotel load, port operations, grid feed-in).

Classified as a power generation asset, not a propulsion system.

Savings apply to electrical load, indirectly reducing auxiliary generator use 2-20%.

Beyond Uncertainty: Direct Wind Power Measurement for Maritime Decarbonization.

Performance uncertainty remains a major barrier to adopting wind-assisted propulsion (WASP). Savings can swing with conditions, making ROI forecasts difficult.

Our approach is different. Integrating a Vertical Axis Wind Turbine (VAWT) directly on-board provides a critical advantage: it acts as a precise, built-in power meter.

Unlike indirect methods, the VAWT directly measures the exact wind energy available for conversion—no additional sensors or complex models needed. This delivers clarity and confidence for:

Hybrid system management (battery charging)

Direct shaft power for propulsion

Accurate, real-time calculation of fuel savings & ROI

We focus on direct economic results and operational safety. By providing tangible, measurable data, we turn wind from an uncertain variable into a reliable, accountable asset.
