System failure probability of offshore jack-up platforms in the combination of fatigue and fracture
Engineering Failure Analysis, 2011Abstract As it is known, fatigue is the process of damage accumulation in material due to the stress fluctuation. The failure occurs when accumulated damage exceed critical level. In practice, uncertainties are incorporated in fatigue estimation especially in the loads and in the capacity of structures.

Dynamic analysis method of offshore jack-up platforms in regular and random waves
Journal of Marine Science and Application, 2012A jack-up platform, with its particular structure, showed obvious dynamic characteristics under complex environmental loads in extreme conditions. In this paper, taking a simplified 3-D finite element dynamic model in extreme storm conditions as research object, a transient dynamic analysis method was proposed, which was under both regular and ...

Abstract The research came from the project for 400-foot jack-up offshore platform's adaptation to environment. The empirical value of load coefficient is often selected by each Classification Society and the influence of other complex factors on hydrodynamic characteristics is ignored, which may make the result too conservative.

Topology optimization of jack-up offshore platform leg structure
Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment, 2020Jack-up platforms are commonly found in the costal or offshore environment for offshore oil and gas recovering. Pile legs are the main component of jack-up platform, which support the whole platform and suffer from the ocean environment load. Topology optimization method is proposed in this article to find an optimized shape for the leg by maximizing ...

Applied Ocean Research, 2021
Abstract This paper aims to investigate the ventilation characteristics of a main cabin in a JU2000E jack-up offshore platform. A scaled model of the ventilation system was built based on the similarity theory, and the factors (such as the engine shutdown choice, the layout of the air outlets, and the supply air volume) that affect the ventilation ...

Interaction between jack‐up rig foundations and offshore platform piles
International Journal for Numerical and Analytical Methods in Geomechanics, 1987AbstractThis paper presents a study of the interaction between the foundations of a jack‐up rig and the pile foundations of an adjacent steel offshore platform. Parametric solutions are presented to evaluate the effect of the rig footing load on the performance of the pile foundation. Homogeneous and non‐homogeneous soil conditions have been considered.
