LNG/Dual fuel powered fishing boats

Fisheries are enormously important to the economy and well-being of Malaysian fishermen. Most of the fishermen have a specific route and petrol or diesel is widely used as fuel to power their boats. Gasoline fuels have fluctuating fuel prices and also produces higher emissions. One of the solutions...
