Abstract
Bach Long Vi island belong to Hai Phong City. As it is far from mainland and designed as a center for fisheries, fuel/energy services for activities on the island are very important. The project has taken the first steps toward realizing the maritime energy potential of Bach Long Vi Island. Total tidal energy generated in South ports is estimated to produce 1.08GW/h per year. The efficiency of tidal energy in South ports is higher than that in West ports. The amount of wave energy in July and for the entire year is 36.3kW/h and 15.5kW/h, respectively. In addition, the other energy sources such as wind power (the average monthly density of wind energy ranging from 3,578 to 10,635 W/m2) and flow energy (has a value of 200-600W/m2) are also notable.
