Wärtsilä is to upgrade the Wärtsilä RT-flex main engines on two bulk carriers owned by Turkey-based Ulusoy Sealines. The planned engine retrofits and upgrades aim to extend the vessels’ operational life and improve both performance and fuel efficiency, significantly reducing emissions.
Current regulatory requirements – such as those on the Carbon Intensity Indicator (CII) – are requiring the majority of the merchant fleet to become more energy efficient. The aim of the Ulusoy upgrade is to align the engines’ performance with the latest operational profile of the two vessels, both of which have undergone substantial changes since their initial delivery in 2011.
The engines will be upgraded through the integration of Wärtsilä Part Load Optimization (WPLO), Intelligence Combustion Control (ICC), and Fuel Actuated Sackless Technology (FAST) — which reduces the the amount of unburnt fuel in the injector sac and reduces
