Following on those Grimaldi schedules, both the Hoegh Singapore and the CSCC Tianjin are scheduled to initially hit a port in NY and then travel onto the Port of Baltimore two days later. CSCC Tianjin then travels to Jacksonville for a third stop, and then onto Houston for a fourth stop. Baltimore, Jacksonville and Houston are both known ports that FCA uses.I found the attached schedule on Grimaldi's website.
(I can't figure out how to add an inline image to a post.)
I put Baltimore in as the POD, but all three of these ROROs stop in NY first.
If you think it is on the MSC Cristiana, have you tried putting your VIN in MSC's cargo tracking page? I'm not sure if this will work, but it's worth a shot.
Hoegh Autoliners also has a cargo tracking page, that specifically states "enter VIN".
