IIT Roorkee and IMU Visakhapatnam Develop Fuel-Efficient Shipping Solution
A collaborative research effort by the Hydroelectric Simulation Laboratory (HSL) at IIT Roorkee and the Indian Maritime University of Visakhapatnam (IMU-V) resulted in the development of an environmentally friendly and cost-effective shipping solution .
India’s broad coastline is witnessing the development of several new ports even as existing ports are enlarged to accommodate increased volumes of maritime traffic and facilitate future maritime trade. Such growing port infrastructure requires more Short Endurance Vessels (SEMVs) for efficient port operations and administration. The useful life of a generic diesel powered SEMV is almost 20 years, after which it is taken out of service. To achieve sustainable solutions and reduce the carbon footprint in Indian seaports, diesel-powered ships need to be replaced with zero-emission electric ships.
In this collaborative research, HSL researchers adjusted the operation of the power sources (induction generators and diesel-powered batteries) of the tugs so that the load demand could be met while consuming as little fuel as possible.
The research was funded by the Ministry of Ports, Navigation and Waterways. The Visakhapatnam Port Trust provided important information on the different types of vessels, their operational schedules and expected design feasibility.
HSL, in conjunction with IMU-V, is also working on absolute battery-operated SEMV designs and high-efficiency, fault-tolerant marine electric powertrains to produce competent zero-emission SEMVs. As the global battery-electric vehicle market grows, it is predicted that the adoption of long-life lithium-ion batteries would lead to the commercialization of absolute battery-powered SEMV.
Professor Ajit Kumar Chaturvedi, Director of IIT Roorkee, said: “This collaborative research by IIT Roorkee and IMU Visakhapatnam on the design and experimental validation of short endurance marine vessels has shown promising results. We intend to strengthen it so that it can empower our maritime industry ”.
Thanga Raj Chelliah, professor in charge of the hydroelectric simulation laboratory, said: “The joint research efforts of HSL and IMU-V have led to the realization of a fuel efficient shipping solution. The methodologies used in the research yielded significant results, allowing fuel savings of 29.86 percent. This company proves that high quality research can deliver modern, effective, efficient and environmentally friendly business solutions.
