Installation of large-diameter, shallow-set anchors and foundation caissons by use of suction technology has proved valuable. Extending this technology to relatively-small-outside-diameter (OD), deep-set tubes can provide significant cost savings for deepwater well and foundation construction. This new technology incorporates suction techniques targeted at increasing the integrity of structural pipe for deepwater drilling operations. It can also be extended to installation of caissons and foundation piles to accommodate deeper installation for relatively-small-OD (30 to 84-in.) tubes.
