Seafastening for Deep Water Floating Drill Operation

First deep water floating drill operation in the world

Large Diameter Drilling Ltd. (LDD) and Barge Master have combined their expertise to complete a world-first: drilling operations from a diving support and construction vessel (DSCV) in water depths of 270 meters. LDD has successfully completed the installation of seven anchor mooring piles for a Catenary Anchor Leg Mooring Buoy. This was accomplished by integrating LDD’s reverse circulation LD2500 drill rig with Barge Master’s motion-compensated Platform (BM T-700).

Aside from the structural and mechanical design of Barge Master’s motion-compensated platform, TWD provided the structural design of seafastening arrangements for the equipment of the entire deck layout.

Project highlights

  • World-first deepwater floating drill operation
  • The motion-compensated platform significantly improved the workability of the drilling operation
  • Balanced drilling operation – from a floating vessel in highly challenging conditions

As the global wind energy sector expands, a shortage of vessels for handling bigger monopiles is foreseen. Simply scaling up isn’t enough.
