NACC Alicudi is reported to be the world’s first cement carrier equipped with IMO Tier III compliant diesel engines driving the bulk handling system. Converted in 2017 with a Van Aalst dry bulk handling system, the vessel became a unique and state-of-the-art 120m self-discharging cement carrier, with a cement handling system is based on compressors and vacuum pumps, driven by Tier III Scania engines. Together they form the heart of the unique vacuum-pressure system for pneumatic conveyance of cement, fly ash and granulated slag, as applied in over a dozen of vessels in recent years.
The development of the world’s first Scania IMO tier III diesel engines in service has been the fruit of extensive joint engineering of Van Aalst, based in Dordrecht, the Netherlands, and Scania from Sweden. The challenge put forward was to find correct placing of the Scania Selective Catalytic Reduction (SCR) system in the engine room deckhouse, which was smaller as the previous non-SCR equipped engine room deckhouse. This resulted into lowering emissions, but also, and very important for the cement carrier owner, the lowering of the height of the loading system and loading points on board the vessel. This has considerable advantages during her operational life, as she can serve an increased number of ports.
