R/V ' Gunnerus' Performance improvements by the propulsion system retrofit.
One of the vessels investigated in the SIMVAL project, NTNU's research vessel 'Gunnerus', was converted from twin
skeg shaft-line propellers with rudders to Permanent Magnet driven AZiMuth Thrusters (PMAZM) in 2015.
The pictures to the left displays the after body of 'Gunnerus' with the propulsion arrangements before and after the retrofit.

New partner in SimVal
OMAE 2015 papers and presentations
The project partners prepared and presented 5 papers in a special OMAE 2015 session on" Marine Simulation Models and Their Validation Techniques (SESSION 6-1-1)". OMAE 2015 took place in St. Johns, Newfoundland May 31 – June 5. The papers were presented in two sessions. Session 6-1-1 contained the following papers:
In session 6-1-4 Marine Simulation Models II/Canadian Shipbuilding III the paper:
Dynamic Positioning Conference, October 13-14, 2015
Marine Cybernetics presented a paper at the DP Conference in Houston in October. The title of the paper was " DynCap – Full scale validation of a vessel's station-keeping capability analysis" by Øyvind Smogeli, Dong Trong Nguyen, Kristoffer Eida and Luca Pivano.
UTC and SimVal VeSim workshop
In November, Rolls-Royce Marine and MARINTEK held a VeSim workshop in Ulsteinvik. It was a combined UTC (https://www.ntnu.edu/imt/rolls_royce) and SimVal workshop. This workshop investigated several aspects of simulation, from manoeuvring to DP, of the case vessels analysed in SIMVAL.
New captive model tests with NTNU research vessel Gunnerus
Additional PMM tests on R/V Gunnerus have also been performed in MARINTEKs large towing tank in November 2015. Many static drift tests were performed, in addition to a large array of dynamic PMM tests. The tests were conducted first with and then without propulsion. These tests were used to augment and improve earlier results gathered during SIMVAL.

Open water tests with a thruster at different advance angles
In November 2015 MARINTEK performed open water tests with a Steerprop 35 CRP thruster, with the purpose of building a propulsion model of the thruster. This work will form part of a new simulation model for the case vessel to be created in cooperation with Havyard.
