B737 flight crew reported the circumstances leading up to wing tip damage while taxiing into the gat...

Narrative:

We landed on runway 10 after a missed approach due to losing sufficient visual references below minimums (heavy rain) for runway 15R. Runway and all taxiways were wet with standing water; as it had stopped raining just before we landed. We began taxiing to [our assigned gate] via taxiway P and taxiway H. While taxiing down the alley on the east side of the terminal pier; I noted and cleared the wing of a set of air stairs on the right side of the aircraft. Once past; we observed an aircraft parked on adjacent gate; and a provisioning truck parked closely behind it. We observed ground ops personnel moving into position at our gate. The captain was on the taxi line when I shifted my focus out the right windows to see if our wingtip would clear the aircraft; as well as the provisioning truck. As we neared our gate it became clear that the parked aircraft was not a factor; so my focus turned to the provisioning truck. The truck was parked on the terminal side of a drainage grate that runs behind parked aircraft and parallel to the terminal pier. After looking back and forth between the wing and the provisioning truck several times; I judged that we would be clear of the provisioning truck and told the captain; 'you are clear on the provo truck; but I'll keep watching it.' as we passed the truck; the lower portion of the split scimitar winglet struck the ladder on the back of the provisioning truck. The captain immediately stopped the aircraft and made a PA. After waiting for some ground personnel to approach and verify that the rest of the wing was clear of the provisioning truck; we taxied to the gate. This event could have been prevented by stopping the aircraft short of the provisioning truck and waiting for it to move to another location. To prevent another crew from misjudging winglet clearance; provisioning trucks should not park behind parked aircraft in the alley. If they must park in that area; a marshaller should be present to assure clearance for parking aircraft.
