I think current trans-oceanic cargo ships generally run at fairly high fraction of peak power (otherwise they could have saved money buy buying a smaller engine in the first place). Also port operations tend to be pretty fast and efficient these days. Of course, for ships running shorter distances and spending a larger fraction of their time in port loading and unloading, synfuels, hydrogen or for really short routes even batteries are probably going to be a better option.
