A Ship that Derives Energy from Waves


Jonathan Salvador, a marine engineer and owner of shipbuilding company Metallica Marine Consultancy, Fabrication and Services, has redesigned trimaran ships used in the Philippines to make them more energy-efficient. A trimaran is a ship or yacht with three hulls. The new design uses multiple internal combustion engines for initial movement in the ocean and then switches to deriving energy from the ocean’s waves to cruise in open waters.

The new design uses the momentum of wave energy and forces it through machinery to generate electricity, thereby converting kinetic energy into electrical energy. Work on this hybrid trimaran started two years ago and the ship should be ready for use by the end of 2020. It will be put through a three-month trial in early 2021. The ship is large enough to carry 100 passengers, 15 motorcycles and four cars.
