Data Sheet
The Balder was built in Japan in 1978 by Mitsui Engineering & Shipbuilding Company Ltd., and is the sister vessel of the Hermod. 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 Deepwater Construction Vessel (DCV) Balder is capable of a tandem lift of 6,300 t (6,945 short tons). The cranes provide for depth reach lowering capability as well as heavy lift capacity to set 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 waterdepth. The toolbox consists of:
DCV Balder was converted and commissioned in 2001/2002 and has successfully executed various projects since.
