World First for Cement Carrier Tier III Compliance
The NACC Alicudi is setting new standards in the cement carrier market. 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.
The Van Aalst 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, resulting into this great achievement. 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.
Directly after completion of the conversion, the NACC Alicudi entered the trade for a three year contract on the east coast of the United States of America and Canada. This area has been declared a NOx Emission Control Area (ECA) for new built and converted vessels as from January 2016, and the NACC Alicudi is now compliant with the area emission rules.
The new rules under IMO Tier III (NOx Emission Control Areas) envisage a 70 percent reduction in Nitrogen Oxide as well as Sulphur Oxide emissions from diesel engines, considerably more stringent than the EPA 2010 (USA) and EURO 6 (Europe) legislation. The NACC Alicudi is world’s first cement carrier equipped with IMO Tier III compliant diesel engines driving the bulk handling system.
This approach fits well with the (environmental) policies of both NovaAlgoma Cement Carriers (the vessel owners) and McInnis Cement (the end user). The latter one works under the motto: ‘The new cement company: high standards, customer conscious, ecologically sound’. And puts its money, where its mouth is. The new McInnis cement plant in Port-Daniel-Gascons, Quebec, is state-of-the-art, in every way, and so is the new receiving Bronx terminal in New York. As such, the newly-converted NACC Alicudi is a fitting addition to the overall logistic foot print of McInnis, which already consists of another NovaAlgoma vessel, the NACC Quebec.
NovaAlgoma Cement Carriers are very pleased with this vessel which is a major step forward in emission reduction as well as operational flexibility. The McInnis cement company expressed their appreciation of the delivered performance of the bulk handling system which is performing above contractual discharge rates. This enables McInnis Cement to reduce the turn-around time and increase the annual throughput of the vessel.
The high emission standards of the vessel will enable a shift to the NOx and SOx ECA’s of the US Gulf of Mexico, and even Puerto Rico and Hawaii, in future. With this combined technology on board the vessel is well prepared for serving a worldwide emerging cement market for many years to come.
Consequently, the vessel has been nominated for the prestigious International Bulk Journal Awards 2018 as Bulk Ship of the Year.
