A parametric study to enhance the design of Hydrokinetic turbine

Many companies and governmental organizations have announced the aspiration to achieve Net Zero Carbon Emissions by 2050. Hence, electrification and low-carbon energy solutions are among the measures to reduce CO emissions. Seeing the fact that offshore platforms are in the middle of the ocean, and...

description	Many companies and governmental organizations have announced the aspiration to achieve Net Zero Carbon Emissions by 2050.

Seeing the fact that offshore platforms are in the middle of the ocean, and the ocean covers almost 80% of the earth surface, a high hydropower potential from the ocean with 29, 000 MW is extractable from Malaysia. Many of the oil and gas companies are eyeing for an alternative marine energy source for electrification of the offshore platforms such as solar, wind and wave. Unfortunately, many yet seen the potential of the marine current energy by Marine Hydrokinetic Turbine (MHKT).
