Histoire
This deepwater construction vessel was built in 1978 by Mitsui Engineering & Shipbuilding Co. Ltd. in Tamano.
Notes historiques
In 1990 this vessel was anchored in Trincomalee Channel awaiting disposition. Balder and sister vessel, Hermod were the world's first semi-submersible crane vessels. In the early 1980s these vessels set several lift records while operating in the North Sea. Conversion to a DCV was carried out in 2001 by Verolme Botlek BV in the Netherlands. The hull consists of two floaters with three columns each. The transit draught of 12 meters is normally ballasted down to 25 meters for lifting operations, with the floaters (with a draught of 12 meters) are well-submerged, reducing the effect of waves and swell.
