thanks fov. I think I go to the sculpture by Scurvy to place the twenties at least that is what the log indicates. What twenties and what digits?

Dutch,

If you're referring to the painting info that is entered in the log - it refers to the skull panel at the turbine room. When you eat a certain compote, you will see a 8 and 1 (twenties - base 20). You have done this earlier already - this was just a clue. You don't need to do this.
