Data Sheet
The Hermod was built in Japan in 1978 by Mitsui Engineering & Shipbuilding Company Ltd. The ship is 505 feet long and 282 feet wide. Its draft is currently 36 feet, but during our work we take in ballast water to increase the draft to 82 feet. This principle is known as semi-submersible. The Hermod is capable of a tandem lift of 8,100 t (9,000 short tons).
