Please remember to put the name that relates to the IMO number last, so they are together.

@Peter, the search engine of the site only allows for one IMO number in the data, hence a choice has to be made, which in this case was for the nearest by ship. To find this photo of the Chang Hang, a search for that name will be required. So the solution of having two names in the title works well.

OK, Pieter. When I submitted the comment it was for "CHANG HANG" only, as that was the caption for this photo. Including the "SENTOSA" in the heading clears it all up. Thanks. PK.

PFK, the IMO given belongs to the tanker, which is the nearest by ship.

Correct IMO is 7710886 as noted in comments and as per other photos of this vessel.
