Mastervolt Korea Co., Ltd. (CEO Kim Seung-ok) announced that it participated in the ‘6th International Maritime Defense Industry Exhibition (MADEX 7)’ held at the 9st exhibition center in BEXCO, Busan from June 1 (Wed) to 13 (Fri).
Masterbolt Korea is a company that provides customized turnkey solutions from the integrated design of electrical and machinery systems for small and medium-sized ships to delivery and installation. In accordance with the Enforcement Decree of the ‘Eco-Friendly Ship Act’ that took effect in 2020, we supply products such as electric and hybrid propulsion, battlefield integrated systems, and high-performance and ultra-high-speed propulsion systems applied to ships that perform special operations that require high speed to reduce greenhouse gas emissions and The company explained that it contributes to national policy by reducing energy consumption. Not only newly built ships, but also ships currently in operation can be upgraded to eco-friendly ships.
In this exhibition, the water penetration type propulsion system used as the heart of high-speed ships requiring speeds from 30 knots to 80 knots and a hybrid system with four operating modes for eco-friendly ships were introduced.
Mastervolt Korea is Korea’s official supplier of Twin Disc, which is used in military high-speed ships around the world, and is the only domestic supplier of ‘Arneson Surface Drive’, a water penetration type propulsion system. The system is a product that has been recognized for its reliability as a military product based on Twin Disc’s know-how with over 100 years of engineering and manufacturing expertise. For more than 40 years, the company has served worldwide military customers including the United States Army (TACOM), Navy, Marine Corps and Air Force, as well as the Israeli Navy, UAE Coast Guard and BAE Systems.
As such, it is used in high-speed and ultra-high-speed ships of military forces around the world, and based on fast maneuverability of 30 to 80 knots and stable low-water operation, it is said to be performing all-weather missions such as interception missions, search and rescue, coastal defense and port patrol in actual combat. Known. In addition, it has the advantage of excellent controllability and a small turning radius as if running on rails by using vector thrust steering, which allows self-steering of the propeller without a rudder.
Even at high speed, the resistance of the hull is minimized to realize faster speed with less horsepower, exceeding the speed limit of 50 knots for water jets, as well as improving fuel efficiency by more than 15%. Regarding this, Master Volt Korea introduced, “It is a solution that can satisfy the fast mobility of ultra-high speed for self-defense and mission completion.”
In the case of the eco-friendly hybrid system introduced together, it was developed with the goal of minimizing carbon emissions and saving fuel. It is a system that can replace the existing internal combustion engine propulsion with a hybrid propulsion system in accordance with the Enforcement Decree of the Eco-Friendly Ship Act from January 2020, 1. It operates in electric mode at low speed and can operate with engine at high speed, enabling stealthy infiltration, and booster mode that uses both electricity and engine can provide fast maneuverability. In addition, efficient energy use was also cited as a strength because the battery can be charged at any time when the engine is in use.
Starting with Korea’s first commercial electric cruise ship in 2020, the Korea Coast Guard’s hybrid power system and Master Volt Korea’s hybrid system are applied to Haeyang 26, an eco-friendly port patrol boat with a length of 3 meters.
An official said, “If the hybrid system and the water penetrating system are integrated and used in a complex ship, it will be a next-generation ship that can have speed, eco-friendliness, and stealth at the same time in the military.”
On the other hand, MADEX 2023 is a ‘defense exhibition and government subsidy-supported exhibition (Korea Defense Industry Promotion Association)’ for publicity and export promotion of defense and export companies. , Busan Shipbuilding & Marine Equipment Industry Cooperative, Gyeongyeon Exhibition Co., Ltd., and Bexco Co., Ltd. operate it.
