8 Balder: Semi-Submersible again
You got it. The Balder is the world’s biggest semi-submersible crane. The best part about the balder is that it actually is two cranes that can be used in conjunction with each other. The first crane can lift up to 4,000 tons and the second one can lift up to 3,000 tons. One notable project that the Balder was on is the installation of the BP Thunder Horse. The Thunder Horse is the world’s largest semi-submersible platform.
