2 things come to mind.
1. How much is for manufacturing plastic parts?
2. How much fuel are the ships using to carry 40% of fossil fuels?

@winkleink @LaChasseuse this figure is purely fuel. Petroleum for manufacturing isn't counted there so no idea.

As for your 2nd question, I imagine it's a large amount, but generally, cargo ships are quite efficient in terms of mass of fuel consumed vs mass of cargo transported.
