How can a double bonded oxygen to a carbon form additional polar contact to water molecules?

I'm looking at the polar contact shared between a phenol oxygen of an aromatic ring and a double bonded oxygen to carbon of a carbonyl carbon.

Both of these oxygen's are forming polar contacts to water within the protein of interest and I'm confused as how a double bonded oxygen which can only have two bonds form this polar contact of water with it's oxygen?

The interactions with water are not additional covalent bonds, they are Intermolecular Forces. Dipole-dipole and H-bonding are attractive forces between two separate molecules (or two parts of the same, large molecule) but they aren't the same as covalent bonds so it's not like Oxygen is breaking the octet rule or anything.
