Spin-off RFF project: Design and maintenance based on operational data


The aim of the project is to develop a scientific method for converting logged operational data from equipment into useful information for maintenance and design purposes.

The current project is directed towards the offshore industry, using case studies together with the project partners, MacGregor, Cameron, and Certex. However, the methods and algorithms developed will apply to other kinds of machinery as well, wherever solid constructions and moving components are involved.

To do this, we will convert the computationally expensive general methods for fatigue calculation into more specific, simplified models. These surrogate models can then run in real-time with operational data as input, resulting in real-time availability of remaining useful life. With knowledge of how the equipment is actually used, maintenance intervals may be adjusted, and design of future products can be done with much better insight into the actual requirements and needs of the customer.

On October 16, 2017 a working meeting in WP4.3 Protocols and standards for integration of simulation models and co-simulation was held at NTNU Aalesund. Lars Ivar Hatledal is the PhD candidate working in this work-package, Professor Houxiang Zhang is the principal supervisor while Arne Styve (not in the photos) and Geir Hovland are the co-supervisors.

The agenda for the day was as follows:

09:00 – 11:30 Visit to the very impressive infrastructure and collection of 3D simulators available at NTNU Aalesund and their partner Offshore Simulator Centre (OSC). The simulators are used both in teaching, research and external projects with industry partners.

12:15 – 14:30 Presentation by Lars Ivar Hatledal and following discussions about the plans and project focus.

WP4.3 is the first common research activity between the two Mechatronics groups at NTNU Aalesund and University of Agder, and is hopefully the beginning of a long-term collaboration.

PhD Defence at NTNU

Dr. Kevin Koosup Yum defended his PhD thesis titled “Transient Performance and Emmisions of a Turbocharged Diesel Engine for Marine Power Plants: Numerical Simulation and Experimental Investigation” at NTNU on August 24, 2017. The work was performed at the Department of Marine Technology and the Center for Autonomous Marine Operations and Systems (SFF AMOS), NTNU, Trondheim, with Associate Professor Eilif Pedersen as the main supervisor and Professor Asgeir J. Sørensen and Professor Roger Skjetne as the co-supervisors.

New Researcher WP1.3


Viktor Donkov started as a Ph.D. candidate at Aalborg University (AAU, Aalborg) under WP1.3 on 1 January 2017 with Professor Torben Ole Andersen as supervisor. Viktor holds a B.Eng. degree in mechanical engineering (VIAUC, Horsens) and a M.Sc. degree in mechatronic control engineering (AAU, Aalborg). He graduated the master’s degree with his final thesis “Fault Tolerant Control of a Hydraulic Servo-System”. He spent 6 months as a research assistant at AAU between his graduation and the beginning of his Ph.D. studies.

In the SFI he will be working on WP1.3 with a focus on the use of digital hydraulics in secondary control of cylinder drives.

New Researcher WP4.1


Savin Viswanathan will work on WP4.1 Integrated simulation of multi-physical systems in offshore operations, starting on December 1, 2017. Before December 1 Savin worked as a university lecturer in India and he holds a MSc degree in Ocean Technology & Management from Indian Institute of Technology, Madras.

New Researcher WP4.3


Gaute Fotland will work on WP4.4 Multi-domain modeling and simulation, starting on September 1, 2017. He has a MSc degree from NTNU, Mechanical Engineering, Specialization: Product Development and Materials Engineering.

MacGregor Uses Offshore Technologies in Construction Industry


MacGregor plans to use crane- and lifting technologies from the offshore industry to automate and improve processes in the construction industry. The ambition is to let robots mount facade plates in Norwegian construction processes already in 2020.
