Kongsberg Maritime has unveiled its new ship design concept, the Super-Efficient Bulker, which promises to redefine the standards of the maritime industry. This design will allow ship owners to meet stringent future regulatory targets without having to abandon conventional fuels.
Efficient Kongsberg design
In response to increasing regulatory pressure on emissions and fuel efficiency, Kongsberg Maritime, in collaboration with Deltamarin, has developed a vessel that demonstrates that compliance with future regulations is possible using conventional fuels. This design ensures fuel cost savings of between 40% and 50%, depending on the operating profile, addressing a crucial need in the maritime industry.
Oskar Levander, Kongsberg Maritime’s vice president of Strategy and Business Development, said,“Our goal was to design a vessel capable of complying with CII regulations throughout its lifetime, using advanced energy-saving technologies.” This statement underscores the company’s commitment to innovation and energy efficiency.
Kamsarmax transformation
For this study, Kongsberg Maritime selected an 82,000 DWT Kamsarmax bulk carrier, a common vessel size worldwide, as the basis for the new design. This choice was due to global constraints on the availability of low-carbon fuels, making Kamsarmax an ideal candidate for the study.
The collaboration with Deltamarin allowed Kongsberg M. to explore various technologies to improve the efficiency of Kamsarmax. The result is the Super-Efficient Bulker, which incorporates several innovative features, including a unique combination of three tilting rotor sails and two suction wing sails. This hybrid approach maximizes the use of wind energy, adapting to various wind conditions to ensure optimal performance.
Technology for fuel and emissions savings
In addition, Kongsberg has developed a hull form that traps bubbles using an air lubrication system, Kongsberg has developed a hull form that traps bubbles through an air lubrication system, significantly reducing frictional resistance. significantly reducing frictional resistance. This design includes a sloped hull with a 1-degree bow-to-stern slope and vertically rotated bilge keels to keep the bubbles in place, improving fuel economy.
The vessel is also designed to operate at a reduced speed, which balances fuel efficiency with operational feasibility. A speed reduction of 1 knot contributes to substantial fuel savings. substantial savings in fuel, emissions emissions and maintenance costs.
Maximum efficiency in the Super-Efficient Bulker
The vessel integrates a hybrid shaft generator with frequency control, optimizing the use of electrical energy and reducing emissions. This system supports the increased electrical load of wind propulsion devices and air lubrication compressors, improving overall efficiency. Equipped with an Intelligent Energy Management System (iEMS) and route optimization software, the vessel ensures optimal energy use, further improving fuel efficiency and reducing operating costs.
To maintain hull cleanliness and minimize drag, the vessel is equipped with a Hull Skater, contributing to low fuel consumption during operation.
