It's an engine looking towards the back. The top lip of the back end. The wide angle plays tricks with perspective, but there still isn't enough distance from those intercoolers to the front to say we're looking forward.
Again, it's a metaphor for the project being "under construction," so it's dangerous to take things literally, but I'd find it odd the engines were being built on site with the rest of the ship. I'd think an entirely different manufacturer would've made the engines. Must be a helluva shipyard.
