This Philippine Ship Is Powered by Ocean Waves

Ships are among the dirtiest forms of transportation, contributing to around 18 percent of the world’s carbon emissions. One Philippine ship aims to prove that it can be improved. The hybrid trimaran built by Metallica Shipyard and funded to the tune of P76 million by the Department of Science and Technology (DOST) is the country’s first attempt to revolutionize the shipping industry. 

“This hybrid fast craft addresses the growing concern of increased CO2 emissions through the use of hydraulic pumps that harvest energy from the ocean waves,” Enrico Paringit told Mongabay. Paringit is director of the DOST’s Philippine Council for Industry, Energy, and Emerging Technology Research and Development (PCIEERD).

The hybrid trimaran will harness ocean waves to produce auxiliary power for the ship. 

The ship will transform mechanical energy from ocean waves and convert it into electricity through mechanisms in its double outriggers that act as hydraulic pumps. As the ship sails through rough waters, the pumps absorb the waves’ energy, providing extra power to the vessel. The bigger the waves, the more power is produced.

The outriggers, which can generate up to 300 kilowatts of electricity, are only auxiliary power sources of the ship. Its main power source will still come from an independent multi-engine that has a 3000-horsepower drive. The multi-engine build is a precaution against total engine failure. 

Because of its design, the ship has a high energy use efficiency. It has low fuel consumption and low emission. 

The ship’s hull is made of steel. The overall shape of the hybrid trimaran is designed to prevent capsizing. The ship has a passenger capacity of 100 people and can transport four vans and 15 motorcycles.
