SCHIFFSTECHNIK | SHIP

SCHIFFSTECHNIK | SHIP TECHNOLOGY good. It is gratifying to see how the industry moves from monitoring to action, and how much progress is possible with insight-based decisions. »Preliminary results indicate that via digital decision support and effective decision support the ship [a small Danish ferry] can reduce the fuel consumption and the emissions with 10–20 %«, shares Soren V. Hansen (The Navigator) from his experience. Similarly, service provider GreenSteam and tanker operator D’Amico achieve significant fuel savings by using insight from their performance monitoring machine learning models for speed optimization during voyage planning. But the main application lies in deciding when and how to clean the hull. Here, more and more operators and consultants realize that for commonly used antifouling paints cleaning is a doubleedged sword. While directly after cleaning the hull performance is significantly improved, most cleaning methods remove both fouling and paint particles (containing biocides and microplastics). This may lead to premature loss of protection, resulting either in massive performance penalties or the costly need for a premature dry-docking to reapply antifouling coatings. Ports and environmentalists are concerned about release of aquatic invasive species and contamination of port silt. New industry standard Again, insight is the first step towards improvement. The debate on in-water cleaning and its environmental impact has gained momentum over the past two years. Milestones were Jotun’s Hull Skating Solution and associated guideline for Proactive Cleaning of Hull Areas in Port & at Anchorage and Bimco’s industry standard on In-Water Cleaning with Capture, both published in 2020. Both are milestones, but unlikely to be the final word. Changing requirements and regulations meet new (but often yet unproven) technical options, leaving many stakeholders at a loss. The developments are dynamic in many related fields, not just the operational guidelines: new, non-biocidal antifouling solutions and robotic cleaning technology are just two prominent representatives that will feature at PortPIC. The issues are controversial, and the debate in the community sometimes passionate and heated. Politics, science and economy do not always see eye to eye, especially when venturing into fields where we all lack knowledge and experience – we have all learnt that from the Covid-19 crisis. At least everybody can agree on two things: (a) The issues are complex and require further discussion and (b) coming together in person is not only an enjoyable, but an effective way to create and disseminate our collective knowledge. They will all come together, at Hull- PIC/PortPIC 2021, knowledge, insight, technology and people. PPG SIGMAGLIDE ® 1290 The superior hull coating that delivers reduced power demand Our PPG SIGMAGLIDE 1290 fouling release coating generates proven improvements in vessel power. Based on a unique 100% pure silicone binder system, the coating provides instant low friction when the ship moves through the water and also very low adhesion of fouling organisms. This breakthrough technology keeps the hull completely smooth from the outset enabling the ship to glide seamlessly through the water. • Proven speed and power improvement • Long-term smoothness due to surface regeneration • Biocide-free for reduced environmental impact • Optimal performance due to minimal speed loss over the operational period • Increased idle time due to improved slime- and fouling resistance and release Visit ppgpmc.com or contact our office in Hamburg on +49 (40) 73 60 21-0 or CS.Germany@ppg.com 48 HANSA – International Maritime Journal 06 | 2021

SCHIFFSTECHNIK | SHIP TECHNOLOGY Ultrasound anti-fouling made easy Germany-based anti-fouling specialist Hasytec has managed to simplify installation rocesses for its ultrasound technology. In addition, cooperative research initiatives are ongoing. A completely new project is also on its way and will be made public soon The success is still being refined, because despite Corona, big plans are in view. Hasytec is confident, looking back on the recent past with some positive developments. It was in early 2018 when the company presented its self-developed Dynamic Biofilm Protection (DBP) system (HANSA 03|2018). With the help of ultrasound technology, the formation of biofilm and marine growth is permanently prevented. The system is used in vessel-specific components such as seawater cooling systems, sea chests, strainers, pipes and plate heat exchangers or box coolers, but also on propellers, bow thrusters and fresh water generators. The technology is for the benefit of OPEX, increasing vessel safety and reduced CO 2 emissions. In order to prevent biofilm, coatings with heavy metals and other substances that are difficult to break down are usually used in shipping, which become redundant with the use of DBP. In spring 2020, this convinced the jury of the German Innovation Award – which is under the patronage of the Federal Ministry for Economic Affairs and Energy – which Hasytec received in the »Startups« category. However, with the start of the pandemic in March 2020 dark clouds came up for the startup. At this point in time almost all installations worldwide were carried out by Hasytec’s service engineers, says co-frounder Jan Kelling. This presented the company with the big problem of how to sell the technology if there is no way of installing it. Travel restrictions and, above all, the protection of the own employees forced him to act quickly. Fortunately, company contacts from Southeast Asia provided early information about the scope of the whole thing on site. Redesigned and simplified In the end, Hasytec redesigned all of the technology and focused on simplifying the installation process and commissioning for the customer. According to the company this has been successfully implemented. Currently, approximately 80 % of the orders are also installed by customers themselves. In April 2020 the company announced another important step: Hasytec became partner of the EU-funded CHEK consortium. The aim of the project group is to reduce CO 2 emissions in global shipping. The focus is on the combined application of advanced key technologies in shipbuilding. Well-known partners of the project are the University of Vaasa, the World Maritime University, Wärtsilä, BAR Technologies, Cargill, Lloyd’s Register, MSC Cruises, Climeon, Deltamarin and Silverstream. The participants develop two concept ships, a cruise vessel and a bulk carrier, which will be equipped with environmentally friendly and energy-efficient technologies. These include the use of wind energy, batteries, heat recovery, hydrogen as a fuel, air lubrication and ultrasonic anti-fouling. The knowledge gained will be made available to the entire shipping industry after the project has been completed. The European Union is supporting the project with a total amount of 10 Mio. € from the »Horizon 2020« funding programme. Kelling points out that »around 90 % of world trade is currently carried out by sea. This results in an immense potential for reducing and saving CO 2 emissions. We are proud to be part of such an important and groundbreaking project. We look forward to working together and exchanging ideas with our partners. At the same time we are aware of how responsible and meaningful our work is. It is time to usher in a greener and more energy efficient era in shipping.« At the beginning of May, the company announced that over 5,000 transducers had been shipped. These are in operation on over 300 vessels and counting. »The trend is also very positive otherwise,« Hasytec states. At the moment, an important project in the research and development phase, about which no information is to be published yet. The first announcements are planned for autumn 2021. »Just so much: it will make waves«, Hasytec says.
