Our team has been involved from the very early days of large diameter drilling, and now focus on providing leading industry expertise in the application of both subsea and topside large diameter drilling systems.
From pile installation to shaft sinking, we specialise in solving the most technically challenging aspects of the drilling at this scale.
Air lifting, reverse-circulation and dredge pump-based spoil handling systems. Fines removal and plume reduction.
Pile handling and temporary work spreads.
Diligent design, high-quality build, onsite installation and ongoing operational support.
Site investigation, marine impact assessment, reduced noise pollution, spoil handling.
Deviations from contractors’ drilling production rates can have a major impact on a project, with both financial and scheduling consequences. We have a developed a range of tools to independently determine drilling progress rates and cycle times using both spoil extraction flow rates and drill cutter performance.
Our spoil extraction flows rates can determine the amount of spoil that can be entrained in both an air lift pumping system or dredge pump, and draw on the very latest of calculation methods for both, whilst all being supported with empirical evidence and experience.
