Ten months of test sailing using Frugal Technologies fuel optimisation package on the tanker Endelo Swan has shown a fuel saving of 12.2%, which is driving Danish tanker operator Uni-Tankers to install the system on three more ships in the fleet. The Frugal Propulsion package was installed on the Chemical/Oil Products Tanker Endelo Swan during docking in June 2020.
“With Frugal Propulsion, we have a system that enables us to reduce the climate impact of our fleet while at the same time strengthening our competitiveness. Endelo Swan is a strong business case, and it is obvious for us to expand the collaboration with Frugal Technologies,” said Peter V. Stokbro, Technical Director at Uni-Tankers.
Frugal Propulsion is a patented and class-approved on-top system which ensures that the engine and propeller are constantly optimised in relation to draught, load, waves and wind. There are no manual adjustments. “Our system is based on sensors, Big Data and learning algorithms which are constantly getting smarter. For the shipowner, this means that the fuel savings will increase as the system gets to know the ship,” explained Peter Hauschildt, naval architect and CEO of Frugal Technologies.
Frugal Propulsion has been tested and documented on a number of ships at various shipping companies since its development in 2017. These tests show an average fuel saving of 10-15% and an ROI of 6-18 months, depending on consumption. “We have proven that the system works and that it requires minimal modification of the ship. Fuel is by far the largest ongoing expense on cargo ships, and it is not difficult for shipowners to see the potential in this. With Uni-Tankers, we now have an extremely strong case which can hopefully make others follow suit,” says Peter Hauschildt.
Uni-Tankers has initially selected the tankers Fenno Swan, Feo Swan and Lillo Swan for installation of Frugal Propulsion because these ships have roughly the same construction as Endelo Swan. But the company may expand its investments further over the coming years.
“Frugal Propulsion is a new technology with few references, but the documentation behind the system is convincing. We initially had a concern about whether the engine risked overloading. However, Frugal Technologies was able to quickly quell this through performance tests. If the next installations perform as expected, we are ready to invest further,” said Stokbro.
