The car carrier Grand Diamond tied up at pier 9c this afternoon to offload 350 cars.
The ship will likely be heading to Montreal, and needs to reduce its draft to make up up the river. The cars will then be picked up on the way back. the Ship Sailed at 16:00 giving Singapore as its destination. the ship will sail via the Suez Canal. i suspect the cars are either for local delivery, or another ship will be along to collect them.
The ship arrived from New York, and is likely carrying some sort of project cargo. This happened once before, in 2015, the Glovis Century lightened the load to pick up Military equipment. Since then, the car carriers Toscana and Onyx Arrow also tied up at pier 9 for work periods.
