Biaxial Loading of Offshore Monopiles: Numerical Modeling [PDF]
International Journal of Geomechanics, 2017 In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and anisotropic behavior of soil on monopile response.

What happens after oil and gas decommissioning? A global systematic review of marine environmental effects. [PDF]
Ecol ApplAbstract The thousands of oil and gas (OG) platforms placed at sea for fossil fuel extraction have introduced new hard substrate to the marine environment. Over time, these structures can become colonized by a diversity of marine life, fostering novel ecosystems.

General Solution for Laterally Loaded Monopile Foundation under Scour
Journal of Marine Science and Engineering, 2023 Scour is a common phenomenon for laterally loaded underwater piles. The underwater piles used in different projects have different pile head conditions and pile types (flexible and rigid).

Analysis of lateral bearing capacity of wing-monopile with symmetrical wing plates
Shuili Shuiyun Gongcheng Xuebao, 2020 There are many factors that affect the lateral bearing capacity of wing-monopile, among which the number of wing plates, the angle between load direction and wing plates are the main influencing factors. The ABAQUS finite element calculation software was

The turbulent wake of a monopile foundation [PDF]
Renewable Energy, 2016 Abstract An experimental programme is presented, examining the turbulent wake of a monopile foundation in a current. Velocity was recorded across an extensive domain downstream of a model monopile in a 0.5 m deep basin, using an acoustic Doppler velocimeter array. The distribution of turbulent kinetic energy (TKE) is examined across the entire domain.

Active vibration control of a monopile offshore structure [PDF]
Journal of Structural Control, 1999 Abstract In the Danish part of the North Sea monopile platforms with a cylindrical shaft have been used at the exploitation of marginal fields. In the paper a new principle for active vibration control of such structures is suggested.
