FORCE Technology works globally across industries, cultures and markets to identify solutions in these areas and address other challenges for the maritime world.
Our maritime competencies are built on talent and pioneering expertise in maritime technology and services, as we constantly push the boundaries for commerce, competence and cooperation.
Currently (until April 2022) FORCE participate in a project called shippinglab ( https://ship-pinglab.dk/
). Here the goal is to improve the mathematical model (the digital twin) by using machine learning methods on measurements recorded onboard the Scandline Ferry M/F Copenhagen.
Besides improving the mathematical model of the Ferry, FORCE is also interested in performing autonomous port operations, and using machine learning techniques to derive the energy optimal strategy.
2. Berthing operations
A Ferry like M/F Copenhagen that operates the Gedser Rostock route needs to rotate 180 degree two times on one of the transits to let the cars drive forward out. On the Gedser – Rostock route the rotations are conducted when the Ferry leaves Gedser, and again just before it goes to berth in Rostock.
Hence the ferry goes astern out of the port in Gedser. Just outside the port the ferry turns around and when in line with the approach channel heads towards Rostock.
The operation is sketched below (see pdf) where the red dotted line illustrates the port and the channel limits.
The blue line is the track recorded from the ferry, and the orange line is obtained by commanding the recorded control settings to the FORCE mathematical model. Yes, the model needs to be improved, and we are working on that.3. Task
The project consists of deriving a policy/strategy that can be used for autonomous departing the ferry.
The derivation should use Inverse Reinforcement Learning on these expert conducted departures, of which FORCE Technology has gigabytes of data for different transits available for the project.
If time allows, the same method could be used on arrival scenarios.
If time allows, the use of Reinforcement Learning to derive the energy optimal usage of the ferrys control units could be attempted.
4. FT deliveries
FT can deliver sensor recordings for a number of departures/arrivals
FT can deliver a simulator and a python interface to control the simulator
FT can participate in status meetings.
