MIL and Teknova invest in a rope-testing machine


MIL and Teknova invests in a rope-testing machine to better understand how to predict remaining life of steel and fiber ropes.

“The machine lets us reproduce specific failure mode of a rope. By constantly running the rope over a sheave in a controlled environment, we are able to observe how the rope deteriorates and analyze sensor information to learn which data is important for understanding the road to failure. As a result, we will be able to predict, with greater precision, the remaining life of a rope,” says Thomas Meyer, Business Development Manager at Teknova.

The research institute Teknova, based in Grimstad and Kristiansand, is the leader of Work Package 5: Condition Monitoring Technologies in the Center for Offshore Mechatronics – an eight year long research program funded by the Research Council of Norway and hosted by the University of Agder.

WP5 aims to improve offshore maintenance operations by developing technologies and methods that enable condition-based maintenance strategies. Two of the five subtasks studies large diameter steel and fiber ropes, typical for the offshore industry.

“Our goal is to develop diagnostic and prediction algorithms that will replace human judgment by online monitoring technologies calling for maintenance weeks before failure occurs,” says Meyer.

The rope-testing machine is part of the first key equipment to be installed in the Mechatronics Innovation Lab (MIL), which is scheduled to open in Grimstad August 16, 2017.

“The machine will make MIL an interesting venue for producers of ropes and cranes. Heave-compensated cranes rely on a number of ropes that are constantly run back and forth over a sheave. A better understanding of how ropes perform over time, is of great interest and value,” says Meyer.

With a pull force of 30 tons, the 12 meters long machine manufactured in France, is designed to test ropes with a maximum diameter of 3 centimeters. Since most offshore ropes are thicker, Teknova has already applied for funding for a bigger machine, which would be able to test ropes with diameters up to 12 centimeters.

“Such a machine would be the largest in the world. It would instantly propel MIL to be an international test laboratory for offshore rope testing,” says Meyer.

RCN Site Visit to SFI Offshore Mechatronics


Tuesday Sept. 20 the RCN team: Kai Mjøsund, Liv Jorunn Jenssen and Øyvind Veddeng Salvesen had their Site visit to SFI Offshore Mechatronics.

University of Agder as host, presented the status of the Center and presented also the future plans for Mechatronics Innovation Lab. The feedback from RCN was that the SFI Offshore Mechatronics is on track. In the picture above (from the right): Center Director Geir Hovland- (UiA) Special adviser Liv Jorunn Jenssen (RCN), Controller Silje Bartholdsen (UiA), Faculty Director Heidi Kristensen (UiA), Chariman SFI Offshore Mechatronics Leif Haukom (GCE NODE), Adviser Øyvind Veddeng Salvesen (RCN), Deputy Director General Kai Mjøsund (RCN), Head of department Rein Terje Thorstensen (UiA), Adm. manager SFI Offshore Mechatronics Rachel Funderud Syrtveit (UiA), Chief Financial Officer Kjetil Hellang (UiA) and University Director Seunn Smith-Tønnessen (UiA)


The RCN participantans also got a demonstration in the UiA Motion lab, by PhD Research Fellow Sandre Sonden Tørdal. He is doing his work within Work Package 2: Motion compensation, led by NTNU professor Olav Egeland.




MIL: Breaking of first ground


Hard working kids from the Kindergarden “next door”, Hokus Pokus, helped breaking the first ground for Mechatronics Innovation Lab (MIL) today.

Kjetil Hellang, the Financial Director of UiA, guided the audience through speakers like Tor Henning Ramfjord (NOV), Johan Martin Ugland (JBU) and UiA Rector Frank Reichert.
