There may be no better place to study icy conditions than a polar region, which is why 29-year-old doctoral student Lu Liangliang is bound for the Antarctic. As part of the 2019 Weddell Sea Expedition, Lu has boarded logistics and research ship SA Agulhas II, on which Aalto researchers first visited the region in 2012, to study the impact of sea ice on ship hulls.
As with Aalto University’s earlier Antarctic travellers, Lu is interested in the impact of sea ice on loads acting on ships’ hulls, but his scope is wider.
Even though polar ice is melting down due to climate change, ice will continue to be a reality for our oceans and seas. In fact, since the transportation of global goods relies mainly on shipping, studying ship behaviour and ship safety in ice is vital. Finland, for example, relies on Baltic Sea ice breakers to keep routes open for supply and trade all year round. Ice-related research is also growing in significance for the Northern Sea Route, as ice cap melt will likely attract more traffic to the Arctic Ocean in the near future.
Lu and Agulhas II set sail for Antarctica from Cape Town on 6 December and return in the beginning of March – quite a lengthy trip in an area with only occasional satellite connections to keep in touch with friends and family. Before he embarked on the journey, Lu shared his thoughts on the expedition.
What made you interested in ice and ships?
‘I was inspired by the teachers in marine and arctic technology at Aalto. They lead us to a world of ship performance and ship safety in ice, both extremely interesting areas. On the other hand, this topic is getting more and more important.’
‘On the trip I have four research focuses, from micro to macro: ice property measurement and observation; ice condition monitoring; ice load monitoring; and ship motion, manoeuvring and onboard oil spill preparedness’.
What are you packing for the trip?
‘Naturally, I’ll need equipment for ice property measurement and ice coring: for example a thermometer, salinity measurement meter, electronic scale; light table, polarizer, bandsaw, three-point bending machine and ice compress machine. Then, of course, equipment for ice condition monitoring: a stereo camera system, top camera system, side cameras, among other things. For examining ice loads, I’ll be using a built-in ice load monitoring system. Meanwhile, I will also bring additional IMU and GPS devices to record ship motions and relevant positions. For documentation and communication, I’ll have computers and a satellite phone.’
What are your expectations for the expedition?
‘I wish to finish the research focuses successfully and see penguins. We will be sailing over to Weddell Sea, and on one hand I hope we’ll have a lot of ice for research, but on the other hand I hope we do not get stuck in ice. There are also a lot of other scientists on board, and I would like learn about their research and see an AUV (autonomous underwater vehicle) in action to view the underwater conditions in the Antarctic and maybe the wreck of the Endurance.’
How do you plan to contact your friends and family during the long trip?
‘I will try to use WhatsApp, email and satellite phone when possible. I’ll also try to keep a diary to share later.’
What are you going to do to pass the time on the ship?
‘Research, research… writing… and learn from others. Maybe the gym and sauna also.’
Do you have a lot of experience of sea travel?
‘No, actually I only have had a few days’ sail in the Northern Baltic Sea.’
How did you end up at Aalto University?
‘I come from China and worked in Shanghai for two years as a naval architect after graduating with a bachelor’s degree. I then began to rethink things and decided, together with my girlfriend at that time (now wife), to go abroad and learn more about maritime engineering and get a wider picture of ourselves and the world. I studied in Norway for my first year of master’s studies and the second year at Aalto in the Nordic Five Tech programme. After that, I continued to doctoral studies after an internship in France.’
Good luck and safe travels, Liangliang!
