SulNOx is thrilled to announce a successful shipping evaluation with Crystal, the leader in exceptional cruise experiences.
This marks SulNOx’s first public foray into the rapidly expanding cruise market.
The Crystal Symphony, a 51,068 gross tonnage vessel powered by six Wärtsilä-Sulzer diesel engines, took its initial delivery of SulNOxEco while berthed in Athens in April 2024. The evaluation, organised in collaboration with SulNOx master distributor A&S International, spanned May to December 2024. Data revealed an average fuel saving of 3.4% over the period, accompanied by a significant reduction in black smoke emissions – a critical improvement for cruise operators navigating ports and Norwegian fjords.
Roberto Fazi, Senior Vice President of Marine Operations, Crystal, added, “The results of the tests carried out after the introduction of SulNOxEco onboard have proven to be very promising. We observed measurable fuel savings, cleaner engines, and reduced emissions. As sustainability becomes a key driver for growth in the cruise sector, this innovation helps us enhance operational efficiency, reduce our environmental impact, and provide a more sustainable experience for our guests.”
Building on the success of this evaluation, Crystal is willing to adopt SulNOxEco across its fleet, embracing sustainable innovation to meet the demands of a rapidly growing industry. With the cruise holiday market projected to grow from USD 9.2 billion in 2023 to USD 25.4 billion by 2033 (Source: Spherical Insights & Consulting LLP), the need for environmentally responsible solutions has never been greater.
SulNOx CEO Ben Richardson stated: “We are excited to be working with such a well-known brand in the fast-growing cruise ship market. The flip side of this increasingly popular leisure activity is the existing and potential level of environmental pollution from some extremely large vessels. SulNOx is pleased to be part of the solution for the industry, helping to reduce emissions significantly while delivering fuel cost savings and supporting ship operators to meet sustainability and CII goals.”
Angus MacDonald, Director of SulNOx master distributor A&S International, commented: “It has been a pleasure working closely with the Crystal team and the Crystal Symphony crew, demonstrating the emission reduction and fuel saving capabilities of SulNOxEco over the extensive evaluation. The real-world benefits are plain to see, and we’re excited to continue supporting the maritime industry’s journey toward a greener future.”
SulNOxEco’s biodegradable and organic formulation represents an immediate, zero-capex transition solution for industries under pressure to reduce emissions and fuel consumption while meeting regulatory targets.
