London is the leader in electric propulsion systems and they are currently used in the Type 23 frigate and the Type 45 destroyer
Discussions between India and the UK on fully electric propulsion systems will take place during the visit of the British strike group led by HMS Queen Elizabeth, Britain’s largest warship. PA
India and the UK are discussing the UK side’s offer to provide advanced electric propulsion systems for warships at a meeting on Friday that coincides with a visit by Foreign Secretary Liz Truss and from the British Chief of Staff, General Nicholas Carter.
As the country prepares for this meeting, let’s understand what these systems are and how they would strengthen the Indian Navy.
How does an electric propulsion system help warships?
Marine propulsion systems move ships across water and provide a higher standard of safety for the marine ecosystem and are cost effective.
In very simple terms, electric propulsion systems use electrical energy to drive the propeller blades for propulsion.
The UK is the leader in these propulsion systems and they are currently used in the Type 23 frigate and the Type 45 destroyer. It is also in use in the HMS Queen Elizabeth, the UK’s largest warship.
Experts believe that electric propulsion systems have several advantages. First of all, the space required for the installation of electric propulsion machines is very small and compact compared to conventional systems. It also offers improved handling and high redundancy.
Vessels that use this technology are also âgreenerâ, due to lower fuel consumption and lower emissions. The technology is also beneficial because it helps reduce the life cycle cost by reducing fuel consumption and maintenance costs. Vessels that use this technology also show high performance in harsh ice conditions due to the maximum torque at zero speed.
Why this is a boost to the Indian Navy
India has shown a keen interest in this technology and the British company Rolls-Royce has expressed its desire to explore the possibilities of sharing end-to-end solutions for the electrification of future warships of the Indian Navy.
In fact, the company is ready to showcase Indian Navy customers its capabilities to design, build and deliver customized power and propulsion solutions for India’s naval modernization needs as part of the upcoming tour of the United Kingdom Carrier Strike Group, PTI reported.
In this report, Rolls-Royce India & South Asia President Kishore Jayaraman said, âAs India plans the fleet of the future, our commitment to support the country’s self-sufficiency goals and modernization of defense remains as strong as ever. “
âWith our experience supporting the electrification of Royal Navy warships over the years, is of particular importance. It also includes the design and deployment of the world’s first hybrid-electric naval system. And we believe that Rolls Royce can bring great value and learning to any future program planned by the Indian Navy to develop electric warships, âadded Kishore Jayaraman, President of Rolls Royce.
What are the disadvantages of the propulsion system
However, as with any technology, the use of electric propulsion systems has certain drawbacks.
The cost of installing this technology is significantly higher, which makes the ships themselves more expensive. In addition, the efficiency of the electrical installation is lower than that of a conventional system.
To use this technology, the Indian Navy will also need to train its crew, as the system is completely different from the mechanical system. This implies more expense for the Indian Navy.
However, if we compare the pros and cons, electric propulsion seems to be a better bet overall and will pay off in the later stages, which is why India should move towards this goal as soon as possible.
