Deep Water Floating Drill Operation Success with LDD and Barge Master – Video
LDD (Large Diameter Drilling Ltd.) and Barge Master combined their expertise to complete the world’s first drilling operations from a DSCV in water depths in excess of 270m.
The integration of LDD’s reverse circulation LD2500 drill rig with Barge Master’s motion compensation platform (BM-T700) enabled the successful installation of seven anchor mooring piles for a Catenary Anchor Leg Mooring (CALM) Buoy mooring system required in the Limetree Bay Installation project for Imodco Terminals, a subsidiary of SBM Offshore. The location of the buoy is 2km off the coast of St. Croix, in the US Virgin Islands.
The challenging project was unable to use a conventional jack-up barge for the drilling operation due to the water depths, reaching 275m, and the steep slope of the sea-bed of up to 17°.
The structural design of the seafastenings for the Barge Master and the complete deck layout of the seafastenings required for the equipment on the deck of the DSCV were both made by Temporary Works Design BV.
