Cement carrier equipped with IMO tier III compliant diesel engine in a world first

Converted in 2017 with a Van Aalst dry bulk handling system, the NACC Alicudi is setting new standards in the cement carrier market. The vessel is a unique and state-of-the-art 120 m self-discharging cement carrier.

Based on compressors and vacuum pumps, the Van Aalst cement handling system is driven by tier III Scania engines. Together, these are the heart of the unique vacuum pressure system for the pneumatic conveyance of cement, flyash, and granulated slag. Similar systems have been installed in more than 12 vessels in recent years.

The world’s first Scania tier III diesel engines have been developed through the joint engineering of Van Aalst in the Netherlands and Scania in Sweden. The two companies wished to find the correct placing of the Scania Selective Catalytic Reduction (SCR) system in the engine room deckhouse, which was smaller than the previous non-SCR equipped engine room deckhouse.

The result of this was lowered emissions and the lowered height of the loading system and loading points on board the vessel, which was a very important factor for the cement carrier owner. This has had a considerable impact on the cement carrier’s operational life, as it will now be able to serve a higher number of ports.

Shortly after this conversion was completed, NACC Alicudi entered into a three year contract on the east coast of the US and Canada. This area was recently declared a NOX Emission Control Area (ECA) for newly built and converted vessels, a rule with which the NACC Alicudi is now compliant.

ECAs are aiming for a 70% reduction in NOX and SOX emissions from diesel engines, with new rules under IMO tier III. The NACC Alicudi is the first cement carrier in the world to be equipped with IMO tier III compliant diesel engines driving its bulk handling system. This approach has worked well for both the cement carrier vessel owners and the end user.

The high emissions standards of the vessel will enable a shift in NOX and SOX ECAs and, with this combined technology on board, the vessel is well prepared to serve a worldwide emerging cement market in years to come.

The vessel has been nominated for the Bulk Ship of the Year award at the International Bulk Journal Awards 2018.
