It would go into the water, and it would have basically no effect at all.
The amount of heat is many orders of magnitude too low to heat the oceans up.
As long as you don't park in very shallow waters where it would have a local effect.

Isn't this the attitude that got us climate change in the first place?

True. But the scale is still a bit different:
Climate change added 400 ZJ of heat energy to the oceans so far.
If we piped the heat of all datacenters that currently exist into the oceans, that would add 0.001 ZJ per year.
The major issue (for global warming, not local warming) isn't waste heat, it's greenhouse gasses.

Heating the oceans globally would require insane and totally unrealistic scale, but the effect on ecosystem on the immediate surroundings is a good question.

A single ship? Ye, no impact.

Thousands? Well, that will be very noticeable.
