We are happy to announce yet another PhD student welcome to the project. Stian is 24 years old and holds a Masters degree in Engineering and ICT, specialised within Marine Technology. In his master thesis, he has worked with navigation algorithms related to a self-developed low-cost ROV. Alongside his studies, Stian worked with development of ROV's guidance, navigation and control (GNC)-systems at Blueye Robotics. The PhD will focus on navigation of autonomous subsea vehicles aiming towards exposed aquaculture. The plan is to look more closely at the usage of range measurements found through acoustics. To help understanding the problem, a simulator will be developed and used in implementation in a small scale model. Later, the aim is to do tests in large scale facilities. This should contribute in increased usage of autonomous subsea vehicles within aquaculture.
Bent holds a master degree in Marine Cybernetics from NTNU. His Master thesis is about experimental testing of underwater path-following for a Videoray Pro 4 ROV (Remotely Operated Vehicle). Within SFI EXPOSED he will be developing systems for remotely controlled and automated underwater vehicles. This includes the use of ROVs for inspecting fish net or cage conditions as well as verifying the safety of using such systems in the industry. In his spare time, Bent likes to spent time outdoor together with his partner.
EXPOSED is happy to announce DNV GL as a new centre partner. Through the partnership, DNV GL will engage in projects focusing on development of regulations of the aquaculture industry in exposed areas, safety and risk management of marine structures and operations, and design methodology and requirements for novel fish farm concepts. Liv Solveig Olafsson, head of section for DNV GL Noomas says: “It is important for DNV GL to cooperate with leading research groups and industry actors in the development of a safe and sustainable aquaculture industry. Building on our experience and knowledge, we believe that joining forces with the partners in the EXPOSED consortium will provide a strong foundation for this work.”

Hence, they invited The Norwegian Industrial Property office to make landscape analysis together with the Norwegian R&D industry to investigate if this will improve research results and reduce the risk of misprioritising. Please read the report on The Norwegian Industrial Property's website.
We look forward to welcoming Malthe Hvas, a MSc in biology from Aarhus University in Denmark. During his studies he has been working with acid-base physiology, nitrite toxicology and the effect of temperature on oxygen consumption in the striped catfish (Pangasianodon hypophthalmus), a tropical facultative air-breathing fish of great socioeconomic importance in Vietnamese aquaculture. His primary task within SFI EXPOSED at The Institute of Marine Research will be to define peak water current thresholds that secure acceptable welfare in farmed Atlantic salmon. For this purpose a large swim tunnel system has been developed at The Institute of Marine Research, which for the first time gives the opportunity to asses swimming performance in groups of Atlantic salmon during various conditions such as different temperatures, hypoxia and stress. Furthermore, he will also investigate swimming capabilities in commercial facilities and in experimental push cages. Malthe is looking forward to produce new and exciting knowledge about [...]
Annual report 2015 (click to read) The Annual report for 2015, the initial year of the centre, is currently available. The report describes the vision, organisation, plans as well as initial results from the centre. Eight initial projects have been defined for 2015/2016 and onwards. In 2015, an initial project (P1) has documented the knowledge base and innovation opportunities. Other projects have focused on developing methodology (P5), establishing research infrastructure (P8), carrying out preliminary studies (P4) and initiating PhD candidates (P6 and P7). Full project activity will commence in 2016. To support cross-disciplinary innovation and good communication within the centre, the centre has arranged a two-day EXPOSED Days during spring and a one-day EXPOSED Day during autumn. Such events will be arranged yearly, in addition to PhD/post-doc workshops and more targeted project related meetings. The EXPOSED Days will serve as a meeting place for innovation, presentation of results, [...]
Field experiments for testing and verification of new technical solutions for exposed aquaculture sites are expected to be a major part of the work in SFI Exposed. To facilitate such experiments, the three aquaculture companies participating in Exposed have all chosen a site where the conditions are among the most difficult with respect to wave and currents. This will ensure that new technical solutions can be tested in realistic conditions. During the project period, new and even more exposed sites can be used for experiments. Technical solutions for e-Infrastructure will be established at all these sites. In addition to instrument cabinets with standardized interfaces for digital and analogue sensors, local PC's for data logging and battery backup will reduce the risk of loss of data. All data are transferred to database servers at SINTEF SeaLab over broadband data links, with redundancy over permanent encrypted links over a mobile network. In [...]
A new doctoral project run by SINTEF Fisheries and Aquaculture and EXPOSED, will focus on work safety for employees in the aquaculture industry. Senior scientist and now a PhD student at NTNU Ingunn Marie Holmen will look at HES and limiting the risk of accidents and injuries in the industry. Good surveillance and monitoring of safety and risk during operations will provide safer operation of the facilities. - The aquaculture industry is growing and there is a need to systematize knowledge and identify best practice in terms of safety management. This becomes increasingly important as the aquaculture farms, and thus jobs, eventually move further offshore, making sites more exposed which poses new challenges. Crew and equipment are increasingly at the mercy of the forces of nature and must adhere to more extreme weather, including stronger wind, waves and stronger currents, explains Holmen. - A special focus will be assigned operations where the most serious accidents occur, [...]
Exposed have been collaborating with students at NTNU Department of Product Design to get fresh visions and views on the future of aquaculture. The students handed in their assignments where the focus has been on control room on land, the barge and various cages. […]
Pål Takle Bore is 25 years old, born and raised in the city of Stavanger, Norway, and holds a Master of Science degree in marine technology from NTNU with specialization in hydrodynamics and marine structures. We are looking foward to his contributions to the EXPOSED centre! The topic for his PhD is related to “exposed aquaculture”. The plan is to investigate hydrodynamic loads, load effects, structural resistance and reliability by performing advanced nonlinear analyses in time domain and, if possible, validate this against experimental results. This will contribute to a better understanding of the governing physical load phenomena relevant for an exposed aquaculture structure and the resulting structural response. Based the results, the goal is to develop rational and knowledge-based design criteria for main components of fish farm structures to be used in an industry expanding toward more exposed locations.
