Red cargo ship with pier and a tower crane set? When I was a child (~15-20 years ago) I remember I had a LEGO set composed by a red cargo ship, with a pier and a tower crane that supposedly moved blocks from the pier to the ship.

The name of the ship was Titan, or Atlantic I think.

Can someone find the name of the LEGO set and maybe a picture?
Based on your description, the set is Launch and Load Seaport (6542):



It was released in 1991, and it matches everything you described including a ship called "Atlantic", so this has to be it. If you're looking for some nostalgia, you can pick this up on Bricklink for ~$150.
