The heart of a ship is its engine and propulsion system. Achieving the goals
of the IMO’s Initial GHG Strategy will require a mixture of innovative
technical and operational solutions that are applicable for use in ships in
both practical and pragmatic terms.
Among all the solutions that are currently undergoing R&D in this regard, an
electric and hybrid propulsion system is being heralded as one of the
leaders. Taking the fullest possible advantage of all the data accumulated
during its decades-long experience and expertise in state-of-the-art diesel
and gas engine technologies, as well as its enviable record of close
cooperation with recognized industry experts in electric power components,
Hyundai Heavy Industries has launched a program called the HiMSEN Hybrid
Propulsion System.
Its goals include minimizing fuel oil consumption and GHG emissions by
means of variable speed operations, the strategic sizing of operating
components, and optimized operational modes.
Our fully electric-powered system comes equipped with HiMSEN Diesel and Dual Fuel main generator, power converting systems, propulsion motors, propulsion units, energy storage systems (i.e., batteries), and control systems. The HiMSEN engine is designed for use with variable engine speeds leading to reduced fuel consumption. A fully battery-operated propulsion system for use without the HiMSEN engine is also available. A wide range of power options for use with propulsion and other electric consumers is provided. The system’s detailed power capacity will be determined during the design phase, through a thorough investigation of the intended ship’s operational profile.
High-efficiency dual-fuel diesel engine generator
Motor drive/Grid Protection/Power Conversion
Spinning reserve/peak shaving
Optimized control with motor drive system
Direct Propulsion/Azimuth Thruster
A hybrid propulsion system with shaft generators Power Take Out, Power Take In, and Power Take Home can be used with a shaft generator. Our hybrid propulsion system comes equipped with HiMSEN Diesel and Dual Fuel generators, reduction gears, power converting systems, shaft generators/motors, and control systems. An Engine-mounted generator (EMG), HHI’s own shaft generator, is also applicable for use with 2-stroke main engines, resulting in minimal cargo loss.
