Balder was built in Japan in 1978 by Mitsui Engineering & Shipbuilding Company Ltd.. 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.
Semi Submersible Crane Vessel Balder is capable of a tandem lift of 4000t (4500 short tons). The vessel has unique capabilities to work at water depths from 70ft and beyond. 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, jackets, moorings, SPARs, TLPs, and integrated topsides. The vessel has extensive ROV capabilities and can lower 300t structures up to 90000ft of water depth.
DCV Balder provides a toolbox for deepwater field development up to 3,000 m water depth. The toolbox consists of:
- DP class III
- Large workdeck area
- Dual crane capability
- Mooring line deployment winch
- Deepwater lowering capability
- Deepwater pile installation capability
- Installation activities from 1 to 4500t
- Works in water depths beyond 70ft
- Flotel services
- High workability semi submersible design with capability to work year-round
DCV Balder was converted and commissioned in 2001/2002 and has successfully executed various projects since.
