New equipment in WP5.6

New equipment for acoustic emissions and a seal test rig have been designed and installed in relation to WP5. The acoustic emission equipment consists of an AE sensor, preamplifier and one channel of an ASIP-2 (dual channel acoustic signal processor). With this equipment multiple AE signals and features can be measured. The seal test rig shown in the image below is intended to investigate failure mechanisms, detection methods and remaining useful life prediction of the seals for hydraulic cylinders. The test arrangement consists of a pressure chamber connected to an electromechanical cylinder.

For questions concerning the equipment get in touch with WP5 leader Thomas Meyer.

Webinars continue in 2021

In the fall 2020 we scheduled short webinars on Teams every second week. The motivation was initially to compensate for the cancellation of the annual conference and workshop. As a side effect we anticipate that the webinars will also result in increased interaction in the center outside of our major events. We have had good attendance with 15 attendees on average. Attendees is a mix between SFI affiliated researchers, from the industry partners and the mechatronics department at UiA. We will continue with the webinars in 2021 every second Thursday from 13.45-14.15.

The preliminary program for Q1-2021 (subject to change): 21/1: Optimization using brute force on GPU (Geir Hovland, UiA)
4/2: Real-time containers (Florian Hofer, Free University of Bozen-Bolzano) 
18/2: Introduction to Julia programming language (Mattias Fält, Lund University) 
4/3:  Host and Build Your Academic/Professional Portfolio for Free using Hugo and GitLab CI/CD (Sondre S. Tørdal, UiA)  
18/3: ONNX – Open Neural Network Exchange (Fabian Bause, Beckhoff)

The same Teams link will be reused for every webinar. A short intro to each webinar will be published in our webinar page. Get in touch if you have a topic you want to suggest or if you have a topic you want to present yourself in a future webinar.

In-Kind Equipment from Cameron

The centre has received equipment from the industry partner Cameron as part of their in-kind contribution in the centre. The equipment consists of the following:

  • Steel wires for testing in WP5 Condition Monitoring Techniques and using the Bend-Over-Sheave (BOS) machine developed in the centre.
  • Various sensors such as encoders and load cells which will be made available to all work-packages, and/or future student thesis projects.
  • 7 rack servers which will be assembled in a cabinet and made available to researchers and students participating in the centre. The servers will be used for, among other things, to test algorithms developed in the centre, for example processing of 3D sensor data, optimization techniques, etc.

Photos of the equipment when it was delivered on December 29, 2020 are shown below:

Annual Progress Report 2020

The annual progress report from SFI Offshore Mechatronics was submitted on December 1, 2020. The report is available for the partners in ProjectPlace. Some of the highlights from the report are listed below:

Every time a PhD candidate defends his or her thesis is a highlight in SFI Offshore Mechatronics. During 2020 as many as 7 PhD candidates defended their theses. These are:

PhD-2: Andrej Cibicik (NTNU), PhD defense on January 8, 2020, Title: Dynamics of Rigid and Flexible Manipulators Using Screw Theory

PhD-3: Alexander Meyer Sjøberg (NTNU), PhD defense on January 30, 2020, Title: Estimation and Control on Lie Groups based on Formulations on the Lie Algebra

PhD-4: Aksel Sveier (NTNU), PhD defense on February 18, 2020, Title: Quaternions and Dual Quaternions for State and Parameter Estimation

PhD-5: Martin Hemmer (UiA), PhD defense on May 15, 2020, Title: Condition Monitoring Methods for Large, Low-speed Bearings.

PhD-6: Sondre Nordås (UiA), PhD defense April 16, 2020, Title: Using Digital Hydraulics in Secondary Control of Motor Drive.

PhD-8: Daniel Hagen (UiA), PhD defense September 2, 2020, Title: Improving Energy Efficiency and Motion Control in Load-Carrying Applications using Self-Contained Cylinders.

Many of the remaining PhD candidates in the centre are in the final phase of their projects, and a similar number of completions are expected in 2021. During 2020 5 new PhD candidates and 3 Post.Doc’s have started. These are the final positions during the lifetime of the centre.

During 2020 a high percentage of the scientific journal publications were at the highest level (Level 2). As many as 6 of 19 journal articles, or 32%, were at the highest scientific level, see:

In addition to producing high level scientific research, the centre also has an ambition to produce results relevant for the industry partners. During the remaining time period the centre management will have a continuous focus on achieving examples of innovation with new work processes, services or products in the industry partners. Another goal which will receive focus, together with the new steering board, is the creation of new projects between the partners. The centre SFI Offshore Mechatronics will officially end in 2023.

Join our Slack group

In 2017, SFI Offshore Mechatronics started using Slack as a collaboration tool. Currently there are 49 members in the Slack group. The Slack group is organized in various channels and each work package has their own channel. Each member can also be reached by direct messaging.  

Slack is an efficient and low barrier way to get in touch with both the center management and the researchers across the different work-packages. We encourage the industry partners to also become members and use this as an opportunity to get in touch and informally discuss relevant topics.  

Most existing members are from the research partners, but we also have some members from the industrial partners. If you are not yet a member you can join by sending an e-mail to and ask for access (include your name and company name if you are working in any of the partner companies).

New Steering Board for 2021-22

During 2020 the centre has had an election committee working to nominate new members to the steering board from the industrial partners. The election committee consisted of Ann Marchioro from GCE NODE and Charlotte Skourup from ABB. The nominated candidates were presented to the General Assembly on November 12 and after the votes the following new board was formed:

  • Tom Fidjeland (GCE NODE), new member of the board and new chairperson
  • Morten Halvorsen (NOV), re-elected member of the board and new deputy chairperson
  • Sjur Henning Hollekim (MHWirth), re-elected member of the board

Webinar series

As the annual conference has been moved to next year we have been looking into how to repurpose some of the planned content for the Smart Tools Workshop. We have planned a series of short 30min presentations on topics relevant to SFI Offshore Mechatronics. We are trying to schedule most of the presentations to Thursdays 12.30-13.00 (CET) every two weeks starting on the 8th of October. The following presentations are planned in 2020.

After the formal presentation (12.30-13.00) you are welcome to grab a coffee and stay in the online meeting for a more informal chat and discussion. If we have sufficient attendance and response for the presentations we will continue with the webinars next year. The topics can be research topics or more practical related to research methods, tools or similar. Get in touch if you would like to give a presentation yourself or have a suggestion for topics. All presentations will be announced here.









SFI Offshore Mechatronics is committed to follow the FAIR principles for scientific data management and stewardship. The FAIR principles provide guidelines to improve the Findability, Accessibility, Interoperability, and Reuse of digital assets.

The center is already using Github to publish source code and now we are adopting to publish datasets. is hosted by University of Tromsø and is based on the The Dataverse Project, developed by the Dataverse Team at the Institute for Quantitative Social Science (IQSS) at Harvard University.

To publish datasets related to our center, we have secured a sub-respository under the UiA Open Research Data repository ( Each dataset published to Dataverse gets a unique DOI identifier which can be referenced in scientific publications. We expect that publishing datasets to will improve reuse of data external to the center but also internally between researchers in the center.

Publishing digital assets and datasets will follow the same internal approval procedures as with scientific publications. If required, datasets can be put under embargo which means that it will not be published before a certain date.

The UiA Library and Open Science coordinators are very helpful and ready to assist with publishing datasets and provide templates and practical guidelines. On October 22nd 12.30-13.00 we will have a webinar with a presentation about data management publishing datasets.

Annual Conference Postponed to November 2021

The Annual Conference of the centre SFI Offshore Mechatronics has been moved from November 2020 to November 2021, due to the still ongoing worldwide pandemic. The Smart Tools PhD Workshop also planned for November 2020 will be re-planned and changed to a digital only event which will take place in 2020.
