Large Diameter Drilling (LDD) and Barge Master have completed what the companies claim to be “a world first” – drilling from a diving support and construction vessel (DSCV) in water deeper than 270 meters.
The two companies deployed LDD’s reverse circulation LD2500 drill rig with Barge Master’s motion compensation platform (BM-T700) aboard the SBM Installer DSCV.
