GUY Energy Solutions’ after-sales department in Augsburg, Germany– Male PrimeServ Augsburg– has actually finished the retrofitting of twin SCR systems aboard the ‘MS Amadea’, a cruise liner hired by phoenix metro Reisen GmbH Bonn (Germany) as well as handled by BSMCruise Services Also called ‘Das Traumschiff’, the Amadea is popular in Germany as the primary recording established for a popular tv collection.
The retrofit established by male PrimeServ Augsburg incorporated an SCR system right into both of the Amadea’s four-stroke male 7L58/64 propulsion-engines to make sure optimum efficiency.
The retrofit mirrors a basic need by phoenix metro Reisen to improve its ecological kindness as well as, extra right away, makes it possible for the vessel to satisfy exhaust requirements in the secret Norwegian Heritage Fjord market. For the task, male PrimeServ prioritised maintaining unsafe discharges to a minimum while keeping engine efficiency as well as propulsion performance.
Bernd Siebert, Head of Retrofits & & Upgrades, male PrimeServ, claimed: “This has been an important pilot project for MAN PrimeServ that ultimately proceeded smoothly despite the restrictions imposed by the Covid-19 pandemic. Notably, we also successfully delivered the SCR systems pre-equipped with honeycombs in order to maintain the tight schedule. Besides some minor, technical adjustments post-installation, we easily reached the required exhaust-gas temperatures for SCR operation and regeneration of the honeycombs in testing. We still need to determine the exact urea consumption required to achieve the necessary NOx reduction, but, fortunately, the engines have been more recently equipped with new MAN turbochargers such that safe operation of the SCR systems is guaranteed.”
The Amadea task called for steel job to vacuum for installment of the SCR systems as well as supplementary systems; the modular SCR system commonly mounted aboard newbuildings was not 100% transferable to a retrofit as well as called for some modifications when it comes to theAmadea Mechanical as well as electric combination, as well as system parameterisation, additionally called for some sources. The official handover of the Amadea to PHOENIX METRO Reisen occurred in mid-January 2022 after category culture approval. Technical Superintendent BSM CS, Bosse Berg, as well as his Engine Team confirmed the effective exhaust decreases throughout appointing of the system as well as specified that they were persuaded by its efficiency.
Siebert included: “This SCR solution establishes PHOENIX Reisen and BSM CS as trailblazers within the cruise segment in terms of emission reduction. Increasingly, we are receiving requests from cruise and ferry companies that want to improve their green credentials and who desire to become sustainable without the need for mandated industry legislation. We have learned many lessons and gained valuable commercial experience from the entire Amadea project that will serve us in good stead on similar projects in the future.”
Technical factors to consider
Male PrimeServ Augsburg formerly retrofitted the Amadea’s turbochargers– at the same time boosting engine performance as well as dramatically minimizing carbon dioxide discharges. The mixed job accomplished on the vessel mirrors male Energy Solutions’ need to significantly end up being a distributor of full propulsion services.
The GUY SCR remedy has actually brought the Amadea’s engines from Tier 0 standing to Tier III exhaust degree, as well as has actually decreased NOx discharges by 90%, comparable to financial savings of 600 heaps per year. Male’s SCR system is the greenest remedy readily available on the marketplace with the greatest functional preparedness as well as safety and security: the SCR will certainly be readily available from simply 15% engine tons, making it possible for tidy procedure, additionally throughout slow-sailing in the arms along with near to port as well as booming locations.
The completely modular SCR remedy has actually additionally been fullly incorporated right into the Amadea’s engine-control set up. With its closed-loop system as well as a climate terminal that makes use of ecological information, the NOx-reduction price is increased as well as ammonia-slip reduced to simply 10 ppm, equivalent to that of an automobile. Low ammonia slip is not simply excellent since ammonia is a greenhouse gas as well as influences the environment, yet additionally since it lowers urea usage, making it possible for the urea-tank dimension to be reduced.
An usefulness research study by male PrimeServ at the task’s start validated the small, modular SCR system’s viability for the minimal room readily available aboard the vessel. Its combination right into the slim channel is just feasible because of the unique 87cpsi honeycombs as well as their high sensitivity in a two-layer slim activator style.
