In 2018, BW LPG had ordered four Wartsila LFSS, with an additional order for eight systems in February 2020.
With the latest order, which was placed in November, Wartsila has to deliver a total of 15 LFSS to BW LPG.
The first order was placed after Wartsila successfully conducted the full-scale testing of the system in 2018, with a complete-sized two-stroke marine engine operating on LPG fuel.
Wartsila claimed that this was the world’s first such testing protocol.
The technology firm has been selected as the system integrator for the retrofitting, which involves not only the installation of the system but also the needed ship design modifications.
BW LPG technical and operation executive vice-president Pontus Berg said: “BW LPG took the first step to invest in pioneering propulsion technology based on excellent test results. Subsequent strong performance of the Wartsila technology has exceeded our expectations, and we have proceeded to equip our fleet with the LFSS as an important step in our commitment towards fewer emissions, bigger savings, and also a large step towards zero-carbon propulsion.”
Wartsila sales and marketing director Kjell Ove Ulstein said: “For any fuel to become viable, it takes more than just an engine capable of burning the fuel. An efficient and well-designed, high-quality fuel supply system is essential, and we have worked hard to bring the Wartsila LFSS to the market. LPG as a marine fuel supports environmental sustainability, and we are proud to be contributing to this.”
Retrofitting of the latest three systems for BW LPG will commence at the end of next year or the beginning of 2022.
Once built, it will be the world’s first green ammonia-fuelled tanker producing no greenhouse gas emissions by 2024.
With a €4.4m grant, Norwegian funding scheme Pilot-E will support the project.
