Abstract
A different technology needs to be used to allow the oil and gas industry to produce more
oil from deeper reservoirs below the seabed. The technology used in the last decades
cannot operate in this depth. A possible technology which could replace the technology
used right now is an all-electric approach. This thesis looks into a potential motor which
could be used for this technology. And is also looking into whether a digital twin can
replace decade-long experiments with prototypes and if it is as good as or even better at
demonstrating safety.
The thesis was conducted in two main steps. In the first step, literature research was
conducted to become familiar with the environment, the research in this field and the
topics in general. In the second step, a Matlab Simulink model of the motor, the motor’s
control unit, and the failures were created.
The thesis showed that a potential for the technology as well as for the digital twin
exists. Due to minor setbacks while creating the models and the unfamiliarity with the
technology, the thesis could only cover the first rotation of creating a model, testing it and
discussing improvements about it. Further work needs to be done to thoroughly verify if
this attempt can provide enough information about the motor and using a digital twin in
a safety demonstration.
