Balder was built in Japan in 1978 by Mitsui Engineering & Shipbuilding Company Ltd., and is Hermod's sister vessel. Balder is 154 meters (505 feet) long and 86 meters (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.

Deepwater Construction Vessel (DCV) Balder is capable of a tandem lift of 6,300 t (6,945 short tons). The cranes provide for a depth reach lowering capability as well as a heavy lift capacity to install topsides. This multi-functional dynamic positioned DCV is tailored for the installation of foundations, moorings, SPARs, TLPs, and integrated topsides, as well as pipelines and flowlines.


DCV Balder provides a toolbox for deepwater field development up to 3,000 m water depth. The toolbox consists of:

DCV Balder was converted and commissioned in 2001/2002 and has successfully executed various projects since.
