Daewoo Shipbuilding & Marine Engineering (DSME) developed the country’s first system that saves marine fuels with wind power. DSME announced that they received a basic approval ‘AIP’ by DNV (Det Norske Veritas) in Norway for the eco-friendly vessel technology ‘DSME Rotor Sail System’ which is able to apply to very large crude oil carrier and LNG carrier and it is one of the next generation eco-friendly supplementary technology and expected fuel economy effect.
Rotor Sail refers to the equipment that secures the power to propel a ship from the column’s rotating power that is generated by the wind during sailing by installing cylindrical column (Rotor sail) on deck of the ship. It has the advantage of being easy to manage due to its large thrust and simple installation compared to its volume of the equipment.
DSME analyzed that if this system is applied more than 5% of fuel saving effect will be shown based on EEDI (Energy Efficiency Design Index) that International Maritime Organization (IMO) presents as an evaluation criterion of energy saving. In turn the shipbuilding industry around the world is paying attention to this system as one of the alternative solutions for reducing carbon dioxide.
DSME sets their sights on self-production of the system for the first in the field. From this the company is expecting to gain a competitive edge in global contracts war and offer their shipowners eco-friendly and high-mileage ships that save the expenses additionally.
DSME is planning to increase their competitiveness in eco-friendly vessel technology by connecting its various fuel saving equipment such as Air Lubrication System (ALS) and Rotor Sail System to ‘DS4’ which is an independent autonomy optimization system that they developed in 2019.
Dong-gyu Choi the president of DSME‘s Central Research Institute (Executive director) said “We are executing our research activities to cope with strengthened global environmental regulation” and “Not only as long-term goals but we will also strive for continuous research targeting a development of ‘Eco-friendly applicable vessel technology’ that global markets demand.”
