Large-scale model tests of a single pile and two-pile groups for an offshore platform in sand

Estimating pile group efficiency for open-ended steel piles in small arrangements is a challenging task designers. This paper reports on the large-scale experimental campaign performed BorWin gamma offshore converter platform, which involved single and two-pile systems scale of 1:10. The works included installation, dynamic end-of-driving tests, restrike static load tests pair groups densely compacted, artificially prepared homogeneous sand. cone penetration test (CPT) profiles blow counts confirmed that foundation are comparable to each other. results system were compared with conventional design methods. Such comparison indicated CPT-based methods load-transfer applicable at considered model scale. bearing capacity prediction obtained via Case Pile Wave Analysis Program (CAPWAP) method conservative respect capacity. A consistent setup effect can be detected by analyzing complete loading session. given was found less than 1.0 both very large soil strains, while it equaled failure.
