EDI 315 into OTM - Where is VesselName stored?

Hi,
We're receiving EDI315 messages from Ocean carriers and one portion of the inbound XML is shown below:
<VesselInfo>
<VesselCode>9459400</VesselCode>
<VesselName>HANSA ASIA</VesselName>
</VesselInfo>

I can see where the VesselCode is stored in the IE_SHIPMENTSTATUS table in the VESSEL_CODE field, but I can't find where the VesselName is stored. I know the Vessel table contains the vessel name, but the VesselName isn't written there when the 315 is received (and I don't believe that it should be). As part of standard OTM functionality, is the Vessel Name stored anywhere?
Thanks.
