To determine the feasibility of new technology designed to dramatically reduce air emissions on seagoing vessels, Holland America Line [part of Carnival] plans on conducting a seawater scrubber feasibility project aboard one of its cruise ships... This innovative project is intended to demonstrate how advanced seawater scrubbing reduces air emissions on large oceangoing vessels. The results will determine whether this technology could be rolled out to new oceangoing vessels, as well as retrofitting existing vessels... Caterpillar will support the project with comprehensive research about the impact of scrubber technology on engine performance, reliability and service life.
