... Salient findings from the studies presented above are summarised below: Introduction Suction piles for deep-water developments present a staple foundation solution. Owing to their excellent holding capacity characteristics in the combined V-H space, suction piles are deployed for a variety...

..., such as drag embedment anchors, are suitable for the semi-taut mooring configurations. For taut mooring configurations, the mooring restoring forces are directly transferred to the anchors; therefore, anchors with higher vertical load resistance such as suction piles and suction embedded plate anchors are more...

... Abstract A computer program has been developed to simulate the landing of suction piles on the seabed. The procedure is based on the dynamic analysis procedure outlined in DNVGL-RP-N103 ( DNVGL 2017 ) and calculates the pile motion as it penetrates the soil using a time integration scheme...

... development. The FSHR consists of a vertical rigid pipe anchored to the seabed via a foundation (e.g. suction pile) and tensioned by means of a near-surface buoyancy can that provides the required uplift force. For the single line FSHR, one flexible jumper connects the rigid riser via a gooseneck to the FPU...
