There was a gap in the science that needed to be filled with high-quality data taken from independent in-situ testing.\u003C\/p\u003E\u003Cp\u003EIt was therefore decided in July 2021 to run our own study to measure all air and water emissions generated by an Oldendorff vessel when operating a scrubber.

Also, it was important that Patritsia and Ievgenii could disembark from the vessel within a maximum of six days, together with several boxes of water and oil samples. The testing of these samples was time-critical, as they had to be sent to a laboratory in Greece for relevant analyses within a specific and narrow timeframe.\u003C\/p\u003E\u003Cp\u003E\u2013 Very low sulfur fuel oil (VLSFO) had to be bunkered at a convenient location, shortly before the commencement of the study, as its quality could deteriorate if left unused for a couple of weeks. In parallel, enough time had to be allowed for the timely availability of the laboratory test results. Before that, the crew had to prepare and clean one of the heavy fuel oil (HFO) tanks onboard.\u003C\/p\u003E\u003Cp\u003E\u2013 Research personnel had to obtain visas and needed to be available at short notice.\u003C\/p\u003E\u003Cp\u003E\u2013 Last but not least, there were a lot of auxiliary equipment and supplies which had to be shipped to the vessel on time.\u003C\/p\u003E\u003Cp\u003EEventually, the chance to send Patritsia and Ievgenii came along. Patritsia has kindly shared her experience with us:\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E\u201cAfter two years of preparing and organizing this study, here I am, finding myself in China for the very first time, standing aboard the huge bulk carrier vessel, \u201cHedwig Oldendorff\u201d, with its awe-inspiring length overall of 299.95 meters! Hedwig was about to start her six-day journey from Taicang to the bustling port of Hong Kong with me onboard. During these six days my mission was to measure gas and particulate matter emissions both below and above the scrubber, at different engine modes and speeds, while the vessel was operating with HFO, and at the same time collect and prepare seawater and wash water samples from the scrubber operation. I also had to measure similar emissions under the same engine modes, while the vessel was burning marine gas oil (MGO) and VLSFO and collect samples for subsequent analysis from all the fuels, lubricants and cylinder oils used during the trip, to enable the renowned apples-to-apples comparison mentioned above.\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EI was so excited at the beginning! We have spent two whole years\u0026nbsp;organizing this study and coordinating all the different components involved to make it happen, including identifying a suitable vessel, sourcing, shipping, and installing onboard the proper equipment, arranging a voyage of specific duration and conditions, synchronizing people\u2019s schedules, and much more. The prospect of embarking on this thrilling adventure seemed both intriguing and exhilarating in theory. I had convinced myself that I knew exactly what lay ahead, confident in my understanding of the tasks that awaited me. However, when reality kicked in, my initial enthusiasm swiftly transformed into daunting fear. As I navigated through the enormous vessel, enveloped in a world of massive roaring engines and intricate machinery, I started being overwhelmed by the complexity and scale of the operation. As I beheld the towering 20-meter vertical ladder, a crucial component of my mission to ascend and descend in order to reach the \u201cabove the scrubber\u201d sampling point and collect data under various conditions, I felt a wave of panic washing over me. The scorching heat, exceeding a blistering 45\u00b0C, made me sweat profusely, with my protective uniform and gear adding to my discomfort. The deafening roar of the engines filled the air, further amplifying my unease. Moreover, the vessel\u2019s constant swaying, as it gracefully rode the turbulent waves, was a detail that had completely eluded my imagination until that very moment. It was in that moment of intense apprehension that I realized the harsh truth: I was utterly ignorant of the true implications behind the phrases \u201cmeasuring emissions onboard\u201d and \u201ccollecting our own, actual data\u201d.\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EThankfully, five extraordinary individuals emerged like superheroes, summoned to alleviate my distress: Lengenii Petrunia, Senior Technical Manager at Oldendorff whose expertise was invaluable; Konfederatov Evgeni, the Master, and the core technical team of the vessel whose support and contributions were priceless: Liashko Igor, the Chief Officer, Omelyanenko Ivan, the Chief Engineer, and Zaytsev Serhiy, the Second Engineer.\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EIt was through the tremendous support of this extraordinary team aboard, that my fear and discomfort gradually dissipated. Their wisdom, respect, and expertise helped me not only to successfully perform the required tests and collect the samples needed, but also to embrace the entire experience with joy. Surpassing my initial trepidation, I conquered my fears of climbing ladders, acclimated myself to the loud sounds of roaring engines, and grew accustomed to the high temperatures. I meticulously set up my own floating laboratory, where I enjoyed preparing and storing my water samples, and begun to like working at the sweating conditions close to the engine and the funnel. After the day\u2019s obligations were fulfilled, we continued our scientific endeavors well into the night. Together, under the dim glow of the vessel\u2019s lights, we toiled tirelessly, undeterred by the hardships that beset us. Though weariness occasionally led to inadvertent errors and moments of frustration, the satisfaction of pushing past our limits and advancing our understanding propelled us forward. As the days unfolded, Hedwig, transformed into a place I could call home.\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EUpon our arrival at Hong Kong, I felt a mixture of satisfaction and pride for our collective efforts, accompanied by a subtle tinge of sadness that our journey had come to an end.\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003ELooking back, I am immensely grateful for this transformative experience that pushed me beyond my comfort zone and allowed me to witness first-hand the intricacies of measuring onboard emissions and collecting actual data. This voyage was not simply a physical journey across the sea nor just another field trip for me; it symbolizes a remarkable chapter in my scientific endeavors, further shaping me as a researcher. I am looking forward to analyzing the results and sharing the outcomes of this unforgettable journey.
