THE YEAR 2014 IN SUMMARY The year 2014 was both interesting and prosperous for the Department of Marine Technology. Nearly 150 Master’s ­Degree students graduated, the highest number ever. The latest number of newly admitted students was also high, and the proportion of female applicants was over 40% for the first time. Approximately 120 PhD students are ­currently studying, which implies that there will be very promising numbers of graduates in the future. The turnover of ­externally financed project activities, including EU projects, was increased compared to previous years. The administrative support including routine for project initiation and follow up was improved and contributed to a positive impact on the general work ­environment and efficiency. By the end of the year, The Research Council of Norway ­announced that 3 of the new Centres for Research-based ­Innovation (SFI), in which we are heavily involved, were to be funded by the Research Council Board. The Centres include the following: • SFI EXPOSED – Exposed Aquaculture Operations (SINTEF Fisheries and Aquaculture AS) • SFI Smart Maritime - Norwegian Centre for Improved ­Energy Efficiency and Reduced Emissions from the ­Maritime Sector (MARINTEK AS) • SFI MOVE – Marine Operations Centre (Ålesund University College) These centres will begin their activities during 2015 and are expected to operate until 2023. In conjunction with SFF AMOS, these centres will further strengthen research ­activities within core areas including the maritime, offshore and aquaculture areas. These centres represent the most important key areas within the marine and maritime areas, so knowledge transfer between the centres is an important issue. Additionally, the management and operation of the new key research area “NTNU Ocean” are located in the ­department; metaphorically, this research area offers an ocean of opportunities.

through the end of 2015. Further, the laboratories and much of the infra­structure requires upgrading and refurbishment, increasing the need for the realization of the Ocean Space Centre (OSC). The strategic government plan for research and higher ­education (Langtidsplan for forskning), launched in ­October 2014, benefits two new infrastructure projects of great ­national importance including the Centre for Life Sciences at the University of Oslo and the Ocean Space Centre at Tyholt. The next phase of the Ocean Space Centre project will fully begin in 2015. Further, the government included “the Ocean” as one of the most important national future research areas in its “Langtidsplan for forskning”. During 2014, the Research Council conducted an ­“Evaluation of basic and long term research within Engineering Science”, in which the department was examined. The outcome of this evaluation will be launched during first half of 2015. In this process, the research groups are evaluated versus their qualifications within the areas of “Scientific quality and ­productivity”, “Relevance and impact” and “Strategy, organization and research cooperation”. During last part of 2014, as a response to an initiative from the Ministry of Education and Research (SAKS), NTNU ­developed a process discussing the option to merge with several other university colleges. It is expected that the NTNU board will convene and form conclusions regarding any mergers during January 2015. The coming year will be challenging, with the beginning of new SFIs, followed by the OSC project. Furthermore, the ­enforcement of the staff and possible mergers between NTNU and several university colleges may also considerably impact the department. The University College in Ålesund is one of the possible merger candidates.

CoE AMOS has progressed very well with the ­establishment of planned activities such as project initiation, ­international co-operation and high PhD engagement. Further, the ­financing of another 5-year gift professoriate has been achieved and is sponsored by the Statoil via the Statoil ­Academia Agreement.

The in-house co-operation with MARINTEK has been success­ful in contributing to the success of the Centre of Marine Technology in the marine and maritime world. The co-operation with other parts of the SINTEF organization has also been important, especially co-operation with SINTEF Fisheries and Aquaculture. Furthermore, the laboratories such as the AUR-lab initiative are under constant development.

Space available at the Marine Technology Centre is ­limited; however, the number of staff is increasing and many new PhD candidates and students are expected. In 2014, an ­office area rebuilding process was begun to allow for room for new employees and students. This rebuild will continue

As in previous years, the co-operation and the day-to-day contact with students are inspiring and constructive. Among other things, the in-house co-operation with both MARINTEK and the students was fruitful in connection with the “Marine Technology Days” (Marintekniske Dager), an arrangement

that occurred at the same time as the student-organized ­“Industry Days” (Bedriftsdagene) at the Centre. The department strives to steadily improve the working environ­ment, and the social event working group has done a good job with many events including the summer and Christmas­­­ parties. The department did also very well in the Trondheim Marathon in September 2014. There are, of course, high expectations with respect to social activities in 2015. Recruitment activities are highly prioritized in the ­Department,­ and several events have been arranged such as “Women’s Day” (Jentedagen) to recruit more female

s­ tudents. Other events include the Ocean Space Race, the Talent Camp during Nor-Shipping in Oslo, participation at the Boat festival in Ålesund and the Researchers Night at NTNU, all to increase the interest of young people in physics, mathe­matics and technology. These activities have proven to be both necessary and highly successful, and they will be highly prioritized in 2015.

EDUCATIONAL PROGRAMMES The department is responsible for the organization and implementation of the Marine Technology educational ­programme at the faculty. It is offered to students in three main options (number of students graduated in 2014 in ­parentheses): - as a 5-year integrated Master programme (106) - as a 2-year Master programme for students with a ­Norwegian Bachelor degree (12) - as a 2-year international Master programme (21) - other Master programmes with a specialization in Marine Technology (10) The first 3 years of the integrated Master programme ­feature introductory courses in mathematics, statistics, physics, chemistry, mechanics, and thermodynamics in addition to courses that introduce the marine disciplines and their ­aspects, design, and operational problems to be ­encountered throughout the programme. From the 6th semester onwards, students can choose among eight specializations: - - - - - - - -

Marine structures Marine cybernetics Marine hydrodynamics Marine engineering Marine operation and maintenance engineering Marine systems design Marine resources and aquaculture Marine subsea engineering

The study specializations combine the disciplines of hydro­ dynamics, structural engineering and marine systems. An emphasis is placed on the students’ ability to ­combine ­practical understanding with the use of mathematical ­models and computer-based methods of analysis. Emphasis is also placed on the development of the students’ ability to view the big picture in technical problems related to design, analysis and operation of marine systems. The 2-year Master of Science programmes in Marine ­Technology is offered to students with a Bachelor degree in Naval Architecture, Ocean Engineering or an equivalent upon admission. The structure of the programmes is built on the courses offered in the last two years of the 5-year ­programme. In addition to Marine Technology, the department is involved in the following programmes: - Engineering and ICT— 5-year integrated Master ­programme - Maritime Engineering— 2-year international Master ­programme (Nordic Five Tech programme, in cooperation with the Technical University of Denmark, the Royal ­Institute of Technology and Chalmers University of Technology in Sweden, and Aalto University in Finland) - Marine Coastal Development— 2-year international ­Master programme - Subsea Technology— 2-year Master programme in cooperation with Bergen University College - European Wind Energy Master— 2-year international Master programme in cooperation with Delft University of Technology, Technical University of Denmark, and Carl von Ossietzky Universität Oldenburg

They offered information on the study programmes of NTNU to pupils at the secondary school level of Norway.

NTNU Jentedagen: 6–7 February A total of 250 female pupils with the highest achievement in mathematics and physics at the secondary school level in Norway participated at NTNU’s Jentedagen for two days. Presentations of the study programmes, social lunches and a dinner in the first evening were on the agenda. On the second day, the girls visited different stands that exhibited NTNU’s broad activities related to mathematics and physics. NTNU’s department of marine technology took part in organizing the stand at NTNU’s Jentedagen.

Ocean Space Exploration Day: 29 April Figure 2 (Pål Leraand, MARINTEK): pupils competing with their model boats at the Ocean Space Race 2014. On Friday, 7 March, 2014, the Ocean Space Race (OSR) ­competition took place at the Marine Technology Centre. A ­total of 442 participants (405 pupils and 37 teachers from 20 different secondary schools of Norway) competed in the Ocean Basin Laboratory to create the fastest, most operative and most stabile ship models and wind turbines. ­Prior to this event, the participants worked for approximately half a year to design and build their ship and wind turbine ­models. The pupils also could listen to exciting lectures about ­ongoing research projects, student life and future job opportunities of the marine industry. OSR has been arranged by NTNU’s department of marine technology in collaboration with MARINTEK and “Samarbeidsforum Marin” annually for

Pupils and teachers at the primary school level of Norway that were offered the “Research in Practice” class were ­invited to have an inspiration day at NTNU. Five different classes from five different regions of the country were ­selected based on their reports from ongoing technological building projects. During this inspiration day, the pupils presented their projects and visited the laboratories of the Marine Technology Centre at Tyholt. Afterwards, they visited Trondhjem Biological Station and joined a fjord-rafting trip to and from a visit to the Research Vessel (RV) Gunnerus. On shore, they could investigate live samples of fish species and marine organisms placed in seawater basins. The fish and marine organisms had been caught that morning by the RV Gunnerus. This event was arranged by the NTNU department of marine technology, NTNU department of biology (Trondheim Biological Station), RV Gunnerus and “Samarbeids­

national students. During 2014, 15 different kinds of visits to the campus were organized. Some visitors at the department of marine technology in 2014:

Forskningsdagene 19–20 September and Researcher’s Night 26 September in ­Trondheim A stand with recruitment activities was arranged at the city centre of Trondheim during “Forskningstorget” on 19–20 September and during Researcher’s Night, “Realfags­ bygget”, on 26 September, at NTNU’s Gløshaugen campus. September 19–20 was dedicated to pupils of primary and secondary schools and the general audience. Pupils at the secondary school level from the middle part of Norway were featured in the evening of September 26.

Courses for Teachers in Secondary and Middle Schools In cooperation with “skolelabben”, NTNU now offers courses for secondary and middle school teachers in technology. In these courses, we offer projects with both a theoretical and a practical approach. All projects are targeted to be applied in the school courses and address certain topics that are part of the curriculum. Workshops have also been arranged for the science centres. The intention of these workshops is to enable the science centres to provide courses and support for schools locally. We have also had requests from institutions that educate teachers and are looking for possibilities to cooperate with them. This activity is a strategic action to set the focus on the marine sector in Norway and increase the interest for working in this sector.

Visitors to NTNU’s Tyholt Campus External visitors came to NTNU’s Tyholt campus ­frequently throughout 2014. These visitors usually wanted to have a look at the unique laboratory facilities of the Marine ­Technology Centre and attend a presentation on the marine ­technology study programme of the department. The most frequent ­visitors were pupils and teachers from both primary and secondary schools in Norway. Occasionally, the visitors were marine industry professionals, politicians, representatives of volunteer associations, NTNU technical personnel and inter-

NTNU Bridgehead Frøya NTNU Bridgehead Frøya (Brohode Frøya) is a regional ­developmental project that links educational institutions with industry and policy implemention systems within the field of aquaculture. The project objective is to mobilize ­higher ­education, strengthen recruitment to the marine ­sector ­industry, and increase the relevance of higher ­education as well as the secondary education level. Since its establishment in 2012, the project has ­directly ­involved and influenced approximately 1000 people. ­Pupils from the secondary education level have been ­connected to students and researchers to inspire higher education in ­marine studies. Connecting students with the ­industry has led to projects and master theses that address ­current ­challenges. Students have also been given insight into the industry by attending events such as akvARENA, Boot Camp, and Aquavitalis, as well as gaining practical ­experience through summer jobs. NTNU Bridgehead Frøya cooperates with aquaculture themed “villages” in the NTNU subject ­Experts in Teamwork (EiT) and provides hands-on ­experience for EiT students with excursions and visits to ­relevant

c­ ompanies. Aquaculture professionals have strengthened their theoretical skills by attending adapted classes in ­continuing education. NTNU Bridgehead Frøya holds a large gathering known as the Bridgehead Conference, a biannual event in which ­pupils, students, researchers, and industry professionals meet to discuss current and future issues for aquaculture. In 2014, NTNU Bridgehead Frøya produced a handbook and film to share its acquired knowledge on how to start and run a cooperative project.

RESEARCH HIGHLIGHTS A list of all of the department’s research projects in 2014 is located in the appendices of this ­annual ­report. The following pages are selected research highlights from several of the department’s ­projects in 2014.

Air-sea Interaction and Transport ­Mechanisms in the Ocean Project manager: Prof. Dag Myrhaug ([email protected]) The ultimate aim of the project is to predict the air-sea ­interaction and the resulting wave-current flow from the free surface to the bottom of the sea. This includes the ­entire dynamics of the wind above the waves, the free surface, and the entire water column from the free surface to the ­bottom; these flows are mutually dependent. To obtain these goals, it is necessary to take the turbulence that exists in the ocean into account by providing good turbulence closure. We are working both with simplified one-dimensional models ­(Reynolds-averaged Navier-Stokes) and three-­dimensional models (large eddy scale simulations), building all our ­models in-house. Our present work includes combined wind-driven and ­tidal flows, seabed boundary layer flow, Stokes surface drift for random waves, sediment transport and wave-current ­interaction at the free surface of the ocean.

Arctic DP: Safe and Green Dynamic Positioning Operations of Offshore Vessels in an Arctic Environment Project manager: Prof. Roger Skjetne ([email protected])

The project “Arctic DP: safe and green dynamic positioning operations of offshore vessels in an arctic environment” was awarded by the Research Council of Norway in 2010 to the NTNU Faculty of Engineering Science and ­Technology and ­industry partners Kongsberg Maritime, Statoil, and Det Norske Veritas for the project period 2010-2014. Its ­vision is for the Norwegian industry to attain world-­leading compe­tence and knowledge of dynamic positioning (DP) ­system technology and operation developed for the safe and environ­mentally robust DP operations of offshore vessels in Arctic environments. The project is managed by Prof. ­Roger Skjetne, who, together with Prof. Lars Imsland and Prof. Sveinung Løset, is the key scientist.

The Arctic DP project conducts research on safe and ­efficient offshore operations in Arctic regions that include the ­dynamic­ positioning (DP) of offshore vessels in sea-ice.

DEPARTMENT OF MARINE TECHNOLOGY | ANNUAL REPORT 2014

The main focus has been on understanding the physics of DP vessel motions in Arctic sea-ice; the development of corresponding mathematical models and numerical simulators; and the use of control theory within the instrumentation and development of the feedback control, observer, and estimation algorithms. Scientific research has been performed in the following three main work packages (WPs): • DP control system redesign • Autonomous ice observation system • Ice management ice load reduction The project ended its main activities in 2014 and marked this by a special edition in the open access journal Modeling, ­Identification and Control (MIC), 2014, Vol. 35, No. 4 (Figure 8). For a printed issue of the journal, please visit the journal: B&W or Color.

Design and Verification of Control Systems for Safe and Energy-efficient Vessels with Hybrid Power Plants (D2V) Project manager: Prof. Asgeir J. Sørensen ([email protected]) Dynamically positioned (DP) vessels with electric power plants in the range of 10-80 MW are used in the offshore ­industry in several safety-critical operations, including drilling, supply, offloading, construction, anchor handling, and production. DP vessels are being increasingly used, and they constitute a major part of the national and international ­maritime activities related to the exploration and exploitation of hydrocarbons and other advanced offshore operations. The development of knowledge and competence in the design and qualification of safe and environmentally robust ­power and energy management systems for ­safer and ­greener offshore vessels is critical for the ­Norwegian ­industry. Highlights for 2014 are the development of a ­simulator of a ­hybrid ­power plant, a dynamic positioning ­system as dynamic ­energy ­storage on diesel-electric ships, and the development of the optimization-based control of diesel-electric ships in dynamic positioning. The D2V projects addresses: • Design and verification of complex systems by system simulations • Analysis of transient and stationary dynamics on fuel ­consumption and gas emissions • Optimal and fault-tolerant control of hybrid power ­systems on ships and rigs - Diesel- and LNG-driven gensets - Energy storage using battery banks, flywheels, etc. - AC and DC systems

Follow-up JIP on Nonlinear FE-methods for Determination of Structural Capacity Project manager: Prof . Jørgen Amdahl (Jorgen .amdahl@ntnu .no) DNV GL, in cooperation with industry partners, has developed guidelines to document the resistance of offshore structures by means of nonlinear FE methods . A recommended practice (DNV-RP-C208) was issued in 2013 . The research project has been considered a success, but it was realized that there was a need to further develop the guidelines . A follow-up joint industry project (JIP) was therefore initiated in 2014 . The project addresses the analysis of accidental actions in general, but the focus is especially on ship collisions and tensile fracture predictions, where the department is heavily involved . Ship collision is important because a significant increase in the design energies according to NORSOK N-003 is expected in 2015 . One of the goals of the project is to establish a shell model library of different bow, side and stern configurations of offshore support vessels for an integrated FE analysis of collisions . As a part of this activity, DNVGL RP-C204 Design Against Accidental Loads is being further developed, notably on ship collisions and accidental fires .

HYDRALAB IV Project manager: Alexandra Neyts (Alexandra .neyts@ntnu .no) Project web page: www .hydralab .eu The FP7 Research Infrastructure project is a European network of unique experimental facilities for studying interactions between water and environmental elements, sediment, structures and ice . Thirty participants from 15 countries collaborate to stimulate transnational access to and improve services provided by existing research infrastructures . NTNU offers access and full-scale field research opportunities at the land-locked Bay of Hopavågen in mid-Norway . Researchers from the Department of Marine Technology were involved in an interdisciplinary study to correlate ecosystem field observations with physical model simulations . HYDRALAB IV was finalised in October 2014 . Its successor, HYDRALAB+, has been retained for funding in Horizon2020 and is expected to start in 2015 .

Low Energy and Emission Design of Ships (LEEDS) Project manager: Prof . Bjørn Egil Asbjørnslett (Bjorn .e .asbjornslett@ntnu .no) The objective of the LEEDS project is to develop knowledge for concept design, system design and technology options for ship design for low energy consumption and greenhouse gas (GHG) emission . The baseline for energy usage and emission level is, to a large degree, set with the ship design . As such, to meet the challenges to reduce energy usage and emission

DEPARTMENT OF MARINE TECHNOLOGY | ANNUAL REPORT 2014

levels from shipping, a continuous line of new ship designs are required . The LEEDS project will contribute both new knowledge of low-energy and low-emission ship design and the education of personnel with the background and confidence to challenge ship and ship system design, and these people can become key personnel in the maritime industry for developing novel solutions for energy and emission reduction . One practical problem is the machinery system selection problem under uncertainty, and a two-stage optimization and decision support process is given in Figure 11 .

infrastructure for both offshore wind and ocean energy converters . The MARINA platform has been coordinated by Acciona, and CeSOS, NTNU has been the scientific lead of the project, which involves 15 other industry, research institute and university partners . Various concepts for generating electric power by combining wind and wave power have been developed with a focus on three concepts, including the STC and SFC concepts developed by CeSOS . The power yield and systems integrity of these concepts have been assessed by methods for integrated dynamic analysis, risk assessment, and experimental methods established in the project . The concepts are hence brought to a preliminary engineering design level with estimates of the power output and costs . The next stage of development, the new resultant multipurpose MRE platform designs, will be the construction of pilot scale platforms for testing at sea . See MARINA’s report summary: http://cordis .europa .eu/result/rcn/55474_en .html

SUSTAINFARMEX - Towards Sustainable Fish Farming at Exposed Marine Sites

Virtual Prototyping of Marine Systems and Operations (ViProMa)

Project manager: Prof. Ingrid Bouwer Utne ([email protected])

Project manager: Associate Prof. Eilif Pedersen ([email protected])

Norwegian fish farmers express ambitions to adopt ­locations farther out on the coast. There are benefits ­related to less ­environmental impact, fewer area conflicts, and ­better production environment for the fish, but there are also ­challenges, e.g., because of higher significant wave heights and stronger currents. In the research project (KPN) ­SUSTAINFARMEX, SINTEF Fisheries and Aquaculture, NTNU and industry partners work together to solve challenges ­related to future fish farming in exposed sites. Research highlights are as follows: • Development and analyses of statistics related to injuries, fatalities and the risk level in aquaculture • Development of concepts for improved interactions ­between vessels, barge, fish, and cages • Simulations and testing of different solutions related to the structural integrity of cages and the welfare of the fish in more exposed locations • Development and testing of improved instrumentation and sensor systems

The objective of this KPN project, awarded by the ­Research Council of Norway to NTNU, University College of Ålesund; SINTEF/MARINTEK and industry partners Rolls-Royce ­Marine; Vard Group; OSC; and DNV GL is to develop a ­common framework for the co-simulation and virtual prototyping of marine systems and operations for cases that are as realistic as possible. One PhD candidate and one post-doc are working on this project together with researchers at SINTEF and MARINTEK. The highlights of 2014 include the release of our first version of the co-simulation bus based on the de-facto standard functional mock-up interface (FMI) and the establishment of workshops where the ­project ­partners have been able to submit, set up and demonstrate co-­simulation for the virtual prototyping of their own ­simulation models working together with models from other partners. Likewise, the simulation bus developed has been adopted by an Innovation project (IPN) called Virtual Sea Trial (VISTA),­which has somewhat similar objectives but from more of a ship designer and end user perspective. This is a very comple­mentary project that enables our project to obtain more user experience and gain more experience by including more relevant cases into the project. Activities that discuss in detail the requirements for component model interfacing and co-­simulation setup are also underway. An open library of the major component models needed for a realistic co-simulation setup for the ­virtual prototyping of a vessel and its system is in its infancy.

RESEARCH CENTRES Centre for Autonomous Marine Operations and Systems (AMOS) Director: Prof. Asgeir J. Sørensen ([email protected]) Web page: www.ntnu.edu/amos

The NTNU Departments of Marine Technology and ­Engineering Cybernetics, together with MARINTEK, ­SINTEF Fisheries and Aquaculture, SINTEF ICT, DNV GL and ­Statoil and ­leading international and national collaborators, were awarded a Centre of Excellence (CoE) by the Research ­Council of ­Norway in 2013. AMOS creates fundamental knowledge and innovates through multidisciplinary theoretical, numerical, and ­experimental research within the knowledge fields of ­hydro­dynamics, structural mechanics, guidance, navigation, and control. Cutting-edge inter-disciplinary research will provide the necessary bridge to realize high levels of auto­ nomy for ships and ocean structures, unmanned vehicles, and marine operations and to address the challenges associated with greener and safer maritime transport, monitoring and surveillance of the coast and oceans, offshore renewable energy, and oil and gas exploration and production in deep and Arctic waters.

Centre for Ships and Ocean Structures (CeSOS) Director: Prof. Torgeir Moan ([email protected]) Web page: www.cesos.ntnu.no The Centre for Ships and Ocean Structures (CeSOS) was ­established as a Centre of Excellence by the Research ­Council­ of Norway (RCN) in 2002 with support from RCN as well as NTNU, MARINTEK, DNV and Statoil. Key ­researchers­­involve professors from the Departments of Marine ­Technology, ­Engineering Cybernetics and Mathematics at NTNU. The centre has been operating in close cooperation with sponsors and scientists from the Technical University of Denmark (DTU), Massachusetts Institute of Technology (MIT), INSEAN and other universities and research institutes. CeSOS focuses on the development of fundamental know­ledge concerning the design and operation of future ships and ocean structures by integrating theoretical and

experi­mental research in marine hydrodynamics, structural ­mechanics­­and automatic control. The support from RCN formally ended after 10 years, as scheduled; however, CeSOS personnel still conduct high-quality research activities as key personnel in AMOS, a new Centre of Excellence. Furthermore, several PhD candidates are affiliated with AMOS. An overview of key personnel, scientific publications and PhD theses during the period of 2002-2012 are available on the CeSOS website: www.cesos. ntnu.no. Since 2013, research activities have primarily been reported through the Department of Marine Technology and AMOS.

Rolls-Royce University Technology Centre (UTC) “Performance in a Seaway” Director: Prof. Sverre Steen ([email protected]) Web page: https://www.ntnu.edu/imt/rolls_royce The University Technology Centre is a research collaboration with Rolls-Royce and focuses on propellers and propulsion research in waves and off-design conditions. Current research focuses on the following: • Renewable energy propulsion using wave foils; the PhD project completed by Eirik Bøckmann. The model test and simulation model for ships with wave foils and a proofof-concept are being developed. The next developmental stage is of a commercially realizable system, in cooperation with Rolls-Royce. • Scale effects of ducted propellers. The PhD project of ­Anirban Bhattacharyya, in co-operation with MARINTEK. The study is based on RANS CFD, at both model and full scale, and advanced model tests are conducted. The ­results explain the main sources of the scale effects on ducted propellers. • Propulsion in waves. The effect of waves on the cavitation­ characteristics and propeller-engine interaction are ­examined. While cavitation is found surprisingly ­unaffected,­the efficiency of an engine decreases as emissions­increase. This is the PhD project of Bhushan Taskar. • Hydrodynamics of merchant vessels with sails; the PhD research of Jarle A. Kramer. • Validation of ship manoeuvring simulation models using both dedicated full-scale trials and data from ships in normal operation; the PhD work of Sergey Gavrilin and the post-doc studies of Afshin Abbasi-Hoseini.

close collaboration with partners from innovative industry and innovative public enterprises.” A short description of each of the three new centres is given below. SFI “EXPOSED” – Exposed Aquaculture Operations Host institution: SINTEF Fisheries and Aquaculture AS The rationale for this research centre is a gradual move ­towards using more exposed coastal areas in aquaculture.

Full scale

There is need for: • more space and fewer areal conflicts • improved production environment with stable conditions and greater dispersal of wastes • locations further from wild salmonids in coastal waters. The SFI shall: • Develop new technologies and competence within aquaculture and other maritime industries. There is a growing national and international market. • Enable safe and profitable operations at exposed fish farming sites. This will be a key to the sustainable growth of the industry.

OCEAN SPACE CENTRE The Ocean Space Centre project made good progress in 2014. Much effort was used to establish understanding for the need of such a centre among decision-makers. Among ­others, a large number of central politicians ­representing many ­Norwegian political parties visited the Marine ­Technology Centre at Tyholt and were informed about the plans. The most important achievement is the promotion of the Ocean Space Centre by Norway’s Solberg government as one of two research and development infrastructure projects that will be prioritized in its Long-term Plan for Research and Higher Education, 2015 – 2024.

In 2014, the Ministry of Trade, Industry and Fisheries (NFD) began to establish a suitable organization to complete the next phase of the technical definition and development of the Ocean Space Centre. The project now answers to the Research and Innovation Department of NFD. Statsbygg, the key advisor to the Norwegian government for construction and property affairs, shall lead the pre-engineering of the Ocean Space Centre concept until the next quality assurance point (KS2), which is expected at the end of 2016. MARINTEK and NTNU will collaborate closely with Statsbygg. The plan is to complete the Ocean Space Centre at Tyholt in Trondheim in 2022.

The Department’s Economy Distribution of financial contribution The income of the department of marine technology is ­generated from two primary sources: - funding from the government for normal operations and strategic restructuring - external funding from private and public contributors for both commissioned and sponsored projects The governmental funding is relatively stable. However, as it depends on both the quality and the quantity of research results, there are some variations in time. Income from commissioned and sponsored projects varies with the economic situation in the industry. Distribution of cost categories Zero-based budgeting is used, having the costs adjusted to the income level. Salary and social costs make up over 65% of the total costs.
