Solving climate change is a huge international challenge

Global warming is caused mainly by human activities, such as increasing concentrations of carbon dioxide (CO2). Human-made carbon dioxide continues to increase above levels not seen in hundreds of thousands of years.

Scientists claim that 3.5 to 4 percent of all climate change emissions are caused by shipping


Confidential data from maritime industry insiders show that just 15 of the world’s biggest ships may now emit as much pollution as all the world’s 760m cars.

In addition, ballast water discharged by ships typically contains a variety of biological materials that can cause extensive ecological and economic damage to aquatic ecosystems along with serious human health problems. the negative impact on the marine environment has been identified as one of the greatest threats to the world’s oceans.

The ‘Hybrid Deballasting Ship’ technology was invented by Nobu Su because the believes that the damage to plankton and nature, will, left unfettered, have a severe impact on global warming and contribute to international problems, such as super monsoons and typhoons.


We are solving this problem by installing our technology that allows vessels to sail out of the harbour with a fraction of the water typically required.
The solution consists in the application a new propulsion system utilizing electricity driven motor in sailing with little Ballast condition. This helps lower water resistance and enhance the efficiency of ballast sailing. With smaller power, ships can sail in little ballast condition.

It was especially developed to reduce CO2 emissions and mitigate the problem of ballast water contamination. Nobu came up with the idea of using hybrid technology to reduce a ship’s requirement for ballast water between 10-20% (depending on the ship’s size), thus minimizing harm to marine life. Meanwhile, the use of a conventionally driven main propeller and an electrically driven duct propeller reduce CO2 emissions because less energy is needed to achieve the required speed.

Nobu Su — “For the shipping industry, a green shift would involve increasing energy efficiency, reducing speeds and shifting to renewable energy and new alternatives to gasoline and other traditional fuels. The ‘Hybrid Deballasting Ship Technology’ is a step in the right direction – a simple yet efficient Ballast Water Management solution offering greater energy efficiency while protecting the marine environment.”
