... configuration penetration settlement installation foundation concept Introduction An offshore jacket structure is designed to support a platform required for drilling and production facilities. The jacket structure is founded in soil through foundation piles which can be of friction piles, suction...

... as a function of existing parameters. The study proved the possibility to delineate ROP values from historical drilling data. Abstract Continuous efforts are made in drilling engineering to identify and develop advanced tools and technologies to maximize rate of penetration (ROP). Optimization of ROP has...

... the success and the ability of high power lasers beam to drill in extremely hard formations. The result showed that the rate of penetration in these formations is much faster than conventional drilling methods. Formations with high compressive strength can prevent or slow drilling and rock penetration. A High...

... of B/4 below the widest cross-section is adopted. This approach was deemed as the most applicable to the soil conditions encounted at offshore oil and gas producing regions in Malaysian Waters as presented by Rohani et al. (2018) . For this study, the jack up rig leg penetration predicted from...

... decommissioning. Installation is done by a discharge of water from the inside of the suction pile, leading to pressure difference between the inside and outside of the suction pile. This causes a net downward installation force, resulting in a penetration of the soil. The reversed principle is used...

... handling requirements. An Asia first was recently achieved on Murphy's Kikeh Spar where 16.77" drilling riser was decommissioned with an engineered, custom designed, mechanized, hands-free system that meets API standards, exceeding client's requirements on penetration of tubular body and cold work over...

... offshore structures located in different soil types including the carbonate sand. During the engineering of one of the fixed platforms in offshore Egypt (Helal platform), adopting Stevens carbonate sand model in 102 m penetration pile, the driveability analysis revealed the need to a hammer with extreme...

... Abstract Sand overlying clay soil profile is typically associated with punch-through risk during preloading. Computation of load-penetration response is usually performed in accordance with methods detailed in SNAME (2008) and ISO (2012) . These methods are based on "wished-in-place...
