[Asia Economy Reporter Choi Seoyoon] Daewoo Shipbuilding & Marine Engineering (DSME) is accelerating the development of eco-friendly and energy-saving technologies in collaboration with the Norwegian classification society.

DSME announced on the 6th that it signed a Memorandum of Understanding (MOU) with the Norwegian classification society DNV for the development of the Rotor Sail System (wind-assisted propulsion device) and fuel-saving device technology at the global LNG business event "GASTECH 2022" held in Milan, Italy. About 20 representatives from both companies attended the signing ceremony.

Currently, energy-saving technology has emerged as a global key issue, with its importance and demand levels gradually increasing. In line with this trend, the shipbuilding and shipping industries are also focusing on securing eco-friendly energy-saving technologies.

The "Rotor Sail System" is one of the next-generation eco-friendly technologies that saves ship fuel by utilizing wind power. It is a device that supplements the ship's propulsion power through the rotational force of a cylindrical pillar (rotor sail) installed on the deck, using the wind generated by the ship's navigation. DSME succeeded in developing the "DSME Rotor Sail System" in March last year and obtained the Approval in Principle (AIP) from DNV.

Through this agreement, both companies will jointly develop the rotor sail system and fuel-saving device technologies and cooperate in promoting related businesses in the future. The main tasks include ▲ pursuing Type Approval Design Certificate (TADC) for the DSME Rotor Sail System ▲ providing technical support related to the rotor sail system ▲ jointly developing other energy-saving devices, and they will begin full-scale research activities.

DSME will lead this technology development activity based on its accumulated eco-friendly technological capabilities and various research achievements. To respond to the International Maritime Organization (IMO) environmental regulations, the company has independently developed and applied various energy-saving technologies to actual ships, including LNG fuel supply systems, Air Lubrication Systems (ALS), Shaft Generator Motor Systems (SGM), and the DS4 (DSME Smart Ship Solution) optimized route proposal system.

DNV, a Norwegian classification society, is a globally accredited classification organization that provides comprehensive risk management, certification, and technical advisory services with a focus on accelerating energy transition across various fields including shipbuilding, marine industries, and the energy sector.

Choi Dong-gyu, Executive Vice President and Head of DSME Central Research Institute, said, "The company continues to strive to meet the diverse demands of shipowners related to environmental regulations," adding, "We will do our best to maintain technological competitiveness that can prepare ahead of market demands."

Meanwhile, DSME plans to produce a full-scale prototype of the "DSME Rotor Sail" in the second half of this year. Following that, by 2026, it plans to establish a "Rotor Sail Demonstration Center" within the Okpo National Industrial Complex in Geoje City, Gyeongnam Province, in collaboration with Geoje and the Disaster Prevention Testing Institute.
