Notes about papers/presenations

Here are my notes from the ICSOS 2020 conference. A lot of the presentation that I found interesting were from NTNU Ålesund.

A dockin simulation framework: model evaluation and expert knowledge data harvesting

A paper by Marco Mirkulec et.al. They have used pygame to make a simple simulation for docking simulations, very cool.

Parameter identification of nonlinear ship maneuvering model using support vector machine method

A paper by Tongtong Wang et.al. about system identification of manoeuvring tests using Support Vector Machine regression (SVR).

  • SVM is better than Least Square Fit in handling initial values and noise.
  • 3DOF Abkowitz model i used
  • Linear kernel in SVM
  • The system identification works extremly good (I’m impressed).

Fast Virtual Prototyping a case study with the RV Gunnerus reaseach vessel

A paper by Pierre Major et.al.

  • Digital twin = predictin an existing ship (usually a lot of measurement data avaliable)
  • Virtual prototype = Nonexistong ship (usually less data avaliable)
  • There were some interesting simulators:
