This is one of Maersk's Triple-E cargo ships. When it's done, it will be the single largest ship humanity has ever built. So, yeah, seeing it under construction is pretty cool.
From Homeworld's shipyards to Star Wars to, well, the real world, there's something awe-inspiring about seeing giant vessels under construction. it gives you a real appreciation as to just how complex these things are, and how much work goes into them.
The Triple-E is about 400m long, and it's so big it can't get through the Panama Canal (it would hit the bottom).
These photos were taken by Alastair Philip Wiper and are making me feel very, very small. You can see more shots at his blog.
