I ran some numbers. This ship can carry 7226 TEU containers; it has a gross tonnage of about 100k tons (93.5k to be precise) [1]. I found that a 5000 TEU carrier has a fuel capacity of 2 million gallons [2]. Since Anna Maersk can carry almost 50% more, its fuel capacity should be larger, but probably by less than 50% because of economies of scale. In any case, replacing diesel with methanol would require at least an additional 3 million gallons, which comes to 10000 tons. That's 10% of the gross tonnage of the ship. I suspect that no ship builder or operator will consider this a negligible amount.
