To prioritize among the wrecks and carry out oil recovery operations where they are most useful, the Swedish Agency for Marine and Water Management (SwAM) has used the risk assessment tool VRAKA, which was developed by Chalmers.</b></p><p>​There are about 17 000 shipwrecks along the coasts of Sweden and the Swedish Maritime Administration, in collaboration with among others Chalmers and SwAM classified 300 of them as hazardous for the environment. About 30 of the shipwrecks pose an acute environmental threat. They contain large amounts of oil that may leak. Shipwrecks leaking oil pose risk to marine life in Swedish waters. Organisms living in the vicinity of the shipwreck are mainly affected but the oil can also spread to other areas with the water currents. </p> <p><br /></p> <p>SwAM has since 2016 had the responsibility to coordinate the investigations and the recovery of oil and ghost nets (old fishing gear that has remained in the sea and lakes that can continue to fish and catch birds, and other marine animals) from shipwrecks. With the help of Chalmers model, they have been able to prioritize among the wrecks. </p> <p><br /></p> <p>“Before we decide which shipwreck to be recovered from oil, we can use the model to estimate the probability of a leak, the volume of oil in the wreck and where the oil is likely to end up in case of an oil leakage” says Fredrik Lindgren, an analyst at SwAM who previously worked on VRAKA during his doctoral studies at Chalmers. </p> <p></p> <h2 class="chalmersElement-H2"><span>To date, 360,000 litres of oil have been </span><span>recovered </span></h2> <p></p> <p><span style="background-color:initial">Since 2017, the model has been used for investigation and oil recovery operations of the six wrecks Thetis, Skytteren, Sandön, Hoheneichen, Lindesnäs and Finnbirch.

SwAM's assessment, however, was that an oil recovery operation is very likely to cost more than SwAM's annual budget for environmentally hazardous shipwrecks in Swedish waters. SwAM has requested funding from the government to increase the budget during a financial year, so that they can recover oil from Skytteren as well. </span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial">From 2018, SwAM was granted SEK 25 million per year until 2027 for research and oil recovery operations.

Initially, they were both attracted by the opportunity to gain international contacts, but that’s not all:</div> <div>“It seemed to be a fun project, and the collaboration with a global industry did not make it any less interesting”, says Aime Vesmes, and Agnes Tunstad nods and adds:</div> <div>“I like boats, and I like renewable energy! In addition, the project seemed to be of good quality.”<br /><br /></div> <div>Aime Vesmes is ending her third year at Mechanical engineering – together with the other two from Chalmers, Gustaf Malmsjö and Johan Kinell – while Agnes Tunstad is studying Automation and mechatronics. The project therefore entailed not only cooperation across national borders, but also across Chalmers’ programmes.</div> <div>“Much of the content is the same in our courses, but there is also a lot of differences. I’m happy for everything that this project taught me about the product development process, as this was completely new to me.

According to the calculations, the payback period is 13 years, and the estimated structural lifetime more than twice as long. The material choices for the garage are guaranteed to hold the least possible risk of rust or other damage, and the panels can also be folded down to protect them from hard weather.<br /><br /></div> <div>Their collaboration has been performed via Zoom, a digital tool for video communication. The eight students were careful not to divide the project into smaller pieces but to try – as far as possible – to cooperate in all parts. This is reflected in the report, they say; otherwise the report could have ended up “choppy”, as a reflection of the fact that different parts were carried out by different persons. The group believe that this is one of the reasons why they won the award. And as Agnes Tunstad says:</div> <div>“What’s the point of a global project if you do not work together?”<br /><br /></div> <div>The response from Volvo Penta has been nothing but positive. In the beginning, the students were in close contact with their contact person, but he also emphasized that he did not want them to be too influenced.</div> <div><div>“If our ideas can bring value to Volvo, I’m happy. That’s what it is all about; for us to be able to give ideas for solutions”, says Aime Vesmes.</div> <h2 class="chalmersElement-H2">Changed plans for the exhibition an advantage</h2></div> <div>The plan was for the Chalmers’ students to travel to Penn State in April. The trip had to be cancelled, for obvious reasons. But the restrictions imposed by the Corona pandemic have not only been negative.

Many different projects are in progress around the world and savings from around 10% to almost 100% is reported. The researchers can share knowledge during this conference and results can be transferred from the advanced racing projects to commercial shipping projects.

This gave Green Cargo the clear sign to use stronger locomotives, with just a few restrictions from the Swedish Transport Administration.</b></p>​In the short term, it means millions of Swedish crowns in savings. In the longer term, it strengthens the competitiveness of train transport and enables the transfer of transport from road to rail. This means reduced carbon dioxide emissions for heavier transport. <div><br /></div> <div>The classification of railway vehicles affects the distances they can operate. The freight train operator Green Cargo needed to install locomotives with greater traction to get a reasonable economy in their freight transport. This meant that heavier locomotives with three-axis bogies would have to operate lanes that were normally operated by lighter, two-axis locomotives. However, the Swedish Transport Administration could not allow the heavier three-axis locomotives to traffic the lanes if the safety could not be guaranteed. The situation was so critical that it became a standing point at the meetings between the Swedish Transport Administration's Director General and Green Cargo's CEO. </div> <div><br /></div> <div>The classification of Green Cargo's three-axis locomotive meant that the locomotive was in a higher class than many lanes have been classified for, which could mean low operating speeds. For bridges, calculation tools are available to analyze the impact of specific vehicles, but for geotechnics the situation was more complicated. An analysis may require expensive and cumbersome soil samples and the remaining geotechnical restrictions were numerous. <img src="/SiteCollectionImages/Institutioner/M2/Nyheter/andersekberg.jpg" class="chalmersPosition-FloatRight" alt="Anders Ekberg" style="margin:5px" /><br /><br /></div> <div><span style="background-color:initial">Anders Ekberg is the director of the competence center Chalmers Railway Mechanics (Charmec). He says that the main challenge for Charmec was to understand the problem. But with the help of the contacts and the understanding built up between Charmec's partners, a solution was soon to be found. </span><br /></div> <div><br /></div> <div>“In a few meetings with intermediate analyzes, we were able to gain insight through the experience and knowledge we have gained in previous projects. Once the solution method was identified, we could relatively easily reach a solution using our numerical tools” says Anders Ekberg. </div> <h2 class="chalmersElement-H2"><span>In-house models from Chalmers provided a solution</span><span>​</span></h2> <div>The researchers from Chalmers proposed a comparative analysis between the stress resulting from a two-axis locomotive and that of a three-axis locomotive. Using in-house models their analysis showed that the marginally lower load per axis of the locomotive actually made the resulting stress in the ground lower for the three-axis locomotive despite this loco having an additional axle. To further analyze load, the Swedish Transport Administration conducted a dynamic analysis using software developed within Charmec.​</div> <div><br /></div> <div>“The analysis supported the conclusion that the locomotives provided a lower load on filling material and the underlying soil. The Swedish Transport Administration was now able to reduce the number of restrictions for Green Cargo's three-axis locomotives” says Ibrahim Coric head of Maintenance Railway system Permission Construction at the Swedish Transport Administration. </div> <div><br /></div> <div>Markus Gardbring is head of Green Cargo's operations and believes that it is of great importance for their operations. </div> <div><br /></div> <div>&quot;Green Cargo can now use stronger locomotives and demolish a large number of circulations for a number of larger customers, which leads to more efficient freight transport and is a prerequisite for us to be able to have more goods on the railway&quot; says Markus Gardbring. </div> <h2 class="chalmersElement-H2"><span>Contributes to reduced carbon dioxide emissions</span><span>​</span></h2> <div>Another benefit is that heavier locomotives with more redundant traction slip less, which reduces maintenance costs. Markus Gardbring also sees gains in the longer term. The Swedish rail network is being rebuilt to allow longer trains. The Swedish government has decided to reduce 70 percent of all carbon dioxide emissions for heavier transport by 2030. The segment that can easily be transferred to rail is intermodal goods. Longer trains are more cost-effective and a prerequisite for enabling competition with trucks in an extremely competitive market. The traction force of the locomotive will be decisive as the weight rather than the length becomes limiting for the number of wagons per train.</div> <h2 class="chalmersElement-H2">Read more about Charmec</h2> <div><a href="/en/departments/m2/news/Pages/Railway-researchers-awarded-for-societal-impact.aspx">Railway researchers awarded for societal impact​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/European-railway-harmony-better-for-the-climate.aspx">European railway harmony is better for the climate​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/Prediction-of-cracking-increases-the-railway%27s-reliability.aspx">Prediction of cracking increases the railway's reliability​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/CHARMEC---A-prerequisite-for-a-functioning-railway.aspx">CHARMEC - A prerequisite for a functioning railway​</a><br /></div>Wed, 06 May 2020 00:00:00 +0200 reality – the future of safe Arctic shipping<p><b>​Maritime traffic in the Arctic region is rapidly increasing which in turn has led to an increased risk of maritime casualties in the region. Now researchers at Chalmers together with the Oslo School of Architecture and Design have developed an AR tool in a VR-environment that will be able to help officers on the bridge to make the right decision under pressure whilst navigating the risky Arctic waters.</b></p>Maritime traffic in the northern Arctic Ocean is now increasing as more shipping-lanes are ice-free for longer periods of time due to the increased melting of sea ice as a result of climate change. However, navigating in Arctic waters is dangerous because of icebergs, rapid weather changes and, in some cases, lack of experience in the ships’ crew. This can lead to accidents and the release of oil and hazardous chemicals for example.<p></p> <p>“As an officer, you need a lot of experience to navigate the shipping routes in the Arctic Ocean. For example, a highly trained eye is required to determine if it is newly formed ice that the ship can easily pass through or if it is hard multi-year ice that can tear the hull”, says Monica Lundh, associate professor and Head of Unit at Maritime Human Factors at the Department of Mechanics and Maritime Sciences.<br /></p> <h2 class="chalmersElement-H2">Safe Arctic Bridge</h2> <p>The research project SEDNA aims to improve the safety of maritime operations in the Arctic. One part of this project is to define the “Safe Arctic Bridge” which has been a collaborative effort between the Oslo School of Architecture and Design and Chalmers. Augmented reality (AR) solutions have been developed based on ship visits, feedback from subject matter experts and simulator exercises that help officers on board avoid hazards such as icebergs, shallow waters and other vessels. In the future, the AR solutions will be based on big data from, for example, satellite, radar, sensors and charts. Katie Aylward, PhD student at the unit for Maritime Human Factors:</p> <p><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/vr-ar320x320.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></p> <p><span style="background-color:initial">“The Arctic environment adds increased pressure on the crew. A unique work environment, paired with information from a variety of sources, presented on different interfaces can be very stressful. This can lead to an inaccurate assessment of a situation, leading to poor decision-making. Our hope is that the AR solutions will give officers the most relevant information for the situation, at the right time to help them make the right decision under pressure in a harsh environment.”</span></p> <h2 class="chalmersElement-H2">Testing in a VR/AR-lab</h2> <p>In order to test the AR solutions safely, they have been developed and implemented in a Virtual Reality (VR) bridge environment. The Maritime Human Factors researchers have created a “VR/AR lab” to test the solutions on both future mariners – students in their last year at the Maritime program at Chalmers, and more experienced mariners – simulator instructors and industry personnel. </p> <p>&quot;To get feedback from mariners with different experiences and with different perspectives is valuable for the continued development and eventual real-world implementation of the AR-tool. We don’t know when it will happen, but the advantage of AR solutions is that they can be applied to existing vessels and are not dependent on redevelopment on the bridge. However, to ensure safe Arctic navigation, I hope it is sooner rather than later,&quot; says Katie Aylward.</p> <p><br /></p> <p><strong style="background-color:initial">Facts:</strong><span style="background-color:initial"> AR is an abbreviation for Augmented reality where digital elements are added to reality in real-time.

An EU project is now underway to investigate the possibilities of hybrid-electric aircraft. Researchers at Chalmers are part of the project and will develop innovative heat management concepts and support aircraft design.</b></p>Few people today doubt that the Earth's atmosphere is affected by carbon dioxide emissions from human activity. The largest sources of emissions come from agriculture, industry and transport. Transport accounts for 25 per cent of global emissions and aviation account for about 3 per cent.<p></p> <p>“A reduction in greenhouse gas emissions is a major key for aviation to continue to contribute to the development of society and the mobility of people. It requires innovative thinking and ambitious research that goes far beyond small improvements.

Recently a first test was conducted where a pilot in South Korea remotely piloted maritime students in the simulator at Lindholmen. The successful test opens new opportunities for international cooperation.</b></p>About 90 per cent of all global transport goes by ship and this requires highly trained crews on the vessels. But before sea captains are ready to work at sea, training is needed to handle ships in many different types of conditions. To mimic different scenarios at sea and in port ship simulators are used.<p></p> <p>Chalmers has Sweden's largest simulator centre for maritime education and research. The simulators at Lindholmen are connected to other simulators around Europe via <em>the European Maritime Simulator Network </em>(EMSN). Thanks to this, several simulators can share in the same digital arena and the simulation of traffic situations becomes as close to reality as possible.</p> <p>“It becomes a lot more authentic when the students can meet other ships that are controlled by other people in the same situation compared to encounter a computer-controlled ship. Also, this will improve the understanding of how others think and communicate. And we as instructors get better conditions to see and coach the way students cooperate on the bridge”, says Mats Gruvefeldt, instructor at Maritime Studies at the Department of Mechanics and Maritime Sciences.</p> <h2 class="chalmersElement-H2">New international cooperation</h2> <p>For the first time, the EMSN has been linked to the Asian counterpart – <em>Asia Pacific Maritime Simulator Network</em> (APMSN). This means that a pilot in on location in South Korea was able to remotely pilot students in the simulator at Lindholmen to virtually dock a large merchant vessel in Busan's port in South Korea. The merchant vessel was also assisted by two tugboats which were operated from Chalmers. Remote piloting may be part of the future of international shipping.</p> <p>“That the test was successful means a lot. It requires advanced technology and good cooperation with everyone involved. In addition, it opens new opportunities for increased international cooperation, which promotes both education and research here at Lindholmen”, says Mats Gruvefeldt.</p> <p><br /></p> <p><strong>Facts: </strong>The European Maritime Simulator Network (EMSN) is technically coordinated by Fraunhofer CML in Germany, where a server connects simulators in Europe. Research on how to develop and streamline shipping with, among other things, remote piloting is conducted thanks to the network. But the network is also used for education of both future seafarers and continuing education for those who are already out in working life.</p> <p><br /></p> <p><strong>Text: </strong>Anders Ryttarson Törneholm</p> ​​Mon, 09 Mar 2020 10:00:00 +0100 facing the big challenges<p><b>Research into everything from galaxies to human health, developing the shipping industry, electric vehicles, material properties and sustainable cities.

The projects come from the Division of Vehicle Safety, which has partnered with Volvo Cars to develop an anatomical shoulder for crash dummies. And from the Division of Dynamics and the National Centre for Railway Mechanics Charmec, who developed virtual tests for crack formation in the rail.</p> <p>&quot;This is a fantastic acknowledgement that the research we conduct really benefits society,&quot; says Angela Hillemyr, head of department and responsible for utilisation at the Department of Mechanics and Maritime Sciences.</p> <h2 class="chalmersElement-H2">Artificial dummy shoulder saves lives</h2> <p>Although standardized crash tests have made car journeys considerably safer over the past 30 years, they have not been totally comprehensive – especially not for oblique frontal collisions. Researchers at Chalmers have developed a crash test dummy that now sets a new, life-saving standard for safety in passenger cars.</p> <p>“We wanted to contribute to a new test standard for oblique collisions. The dummy used previously turned out to be too rigid in the shoulder and did not give a fair representation of how an actual person reacts to a crash that throws the body forward obliquely”, says Mats Svensson, professor at the Department of Mechanics and Maritime Sciences.</p> <p>Read the full article: <a href="/en/departments/m2/news/Pages/Artificial-dummy-shoulder-saves-lives.aspx">Artificial dummy shoulder saves lives​</a></p> <h2 class="chalmersElement-H2">Prediction of cracking increases the railway's reliability</h2> <p>Cracking in rails and wheels is one of the largest maintenance costs for railway traffic. It is also the reason for many delays and stops that can lead to considerable costs for both train companies and track managers. But through methods developed at Chalmers, which predict cracking in rails and wheels, train traffic is now more reliable and environmentally friendly.</p> <p>Anders Ekberg is a professor at the Department of Mechanics and Maritime Sciences and director of Charmec:</p> <p>“More and more railway traffic occupy the same network, which leads to smaller windows for maintenance. But by being able to predict cracking, the risk of operational disturbances, unplanned maintenance and environmental impact is reduced. Then the costs can also be kept down. And that is a necessity for a functioning and efficient railway”, he says.</p> <p>Read the full artice: <a href="/en/departments/m2/news/Pages/Prediction-of-cracking-increases-the-railway%27s-reliability.aspx">Prediction of cracking increases the railway's reliability​</a></p> <div><br /></div> <p><strong>Text: </strong>Anders Ryttarson Törneholm</p> ​Mon, 02 Mar 2020 00:00:00 +0100
