Beaufort Sea, Arctic Ocean
Our client was engaged to design artificial islands used as oil and gas drilling platforms. In terms of solution design, logistics, and operations, this project was extremely challenging. Offshore operations are best executed using elevating boats. However, there were none near the Beaufort Sea. Instead, we specially designed a motion-compensating drill for use on a floating platform.
Equipment: Mobile Augers designed the DGD 2000 drill for offshore use where elevations boats aren’t available, due to either water depth or logistical issues. The drill used a “derrick within a derrick” design that provided absolute stability for the drill head, regardless of the boat’s motion. This design provided extremely accurate drill head control, allowing feeds as precise as 3 mm (1/8 in), and enabled us to obtain excellent core samples from the sub-sea permafrost.
