REPUBLIKA.CO.ID, SURABAYA – Operational vessels that use natural gas can save up to 50 percent. This was investigated by the Professor of the Department of Shipping System Engineering, Sepuluh Nopember Institute of Technology (ITS) Surabaya, Semin.
The Research Professor of the ITS Shipping Systems Engineering focuses on a gas-fueled maritime fleet. Because, the gas is cheaper and has lower emissions. However, so far gas fuel has been exported more than used domestically.
Semin has been researching fishing boats in the Lekok area of Pasuruan Regency. About 400 fishermen were involved in the study. The fishermen facilitated the process of converting fuel from diesel to gas by the Ministry of Maritime Affairs and Fisheries (KKP).
“The fishing boats there have been using gas, it has been running since 2010. Because Pasuruan passed by gas pipelines to Surabaya and Gresik. Fishermen can save 50 percent,” he said to reporters at the ITS Rectorate building in Surabaya on Thursday (7/20) )
According to him, can gas fuel be used on fishing boats, fishing boats, warships, passenger ships? container ships, oil ships and ships to guide large ships. Of all the ships, it can later be converted from non-gas fuel to gas.
Gas fuel consists of three types namely LPG, LNG and CNG. Each has specifications, advantages and disadvantages. His research focuses on CNG type gas fuel. Semin said Indonesia had the 11th gas fuel potential in the world. However, domestic use is still lacking.
He also gave an example in fabric countries such as Singapore and Malaysia, vehicles that use gas fuel are given a one-year tax-free subsidy because they have reduced emissions in their regions.
“Gas fuel has an inexpensive price. One liter of CNG costs one third of a liter of diesel.
For example on a ship the average fuel consumption per hour is 1,000 liters. Diesel fuel costs Rp 7,000 per liter to Rp 7 million per hour. If you use gas, the cost is only around Rp. 2 million, “he said.
He also gave an example, diesel fuel in a car with a 45-liter tank could cover a distance of about 300 kilometers. If using one-cylinder gas fuel is equivalent to 40 liters of diesel, it can travel 300 kilometers. In fact, the price of gas is one third the price of diesel. “If one ferry trip takes nine tubes, the ferry can carry 20 cars,” he said.
