Penetration of jack‐up platform footings into the seabed
Marine Geotechnology, 1987Abstract A three‐leg jack‐up mobile drilling platform operates in the South Baltic. The installation of this unit at each drilling location is preceded by a site investigation, by laboratory soil tests, and by the prediction of leg penetration. A method for the theoretical modeling of the leg penetration process was developed, based on a two‐step ...

Reliability of jack-up platform against overturning
Marine Structures, 1991A probabilistic model for assessing the safety of jack-up platforms against overturning is presented in this paper. Stoke's fifth order wave theory was used to determine the wave kinematics and wave forces acting on the platform. Because of the non-linearities associated with the wave forces, the overturning moment and the non-Gaussian character of the

Lifting Platform in Jack-Up Offshore Platform Based on Virtual Prototyping
Applied Mechanics and Materials, 2012This paper put forward a systematic design method based on virtual prototyping technology to simulate lifting platform of jacking system in jack-up offshore platform. After the main parameters of lifting platform in jack-up offshore platform were introduced, the 800T offshore platform modeling techniques were put forward, such as rigid body modeling ...

Digital Twin of a Generic Jack-Up Platform
Offshore Technology Conference, 2023Abstract A development of physics-based digital twinning of a generic jack-up platform is presented in this paper. Due to lack of field measurement data, a generic large-scale jack-up model was designed, fabricated and tested in TCOMS ocean basin at 1:30 scale under different configurations, with the objective to provide high-quality ...

Ice Loading of Jack-Up Platforms
24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 2, 2005The use of drilling platforms for exploration drillings in ice-covered shallow water is expected to increase in the future. Jack-up platforms (JU) are regarded to be most suitable for exploration drillings due to their high mobility, their facile transportation and installation. Although having proved their capability for harsh environments, e.g.

The Siri Production Jack-up Platform
Offshore Technology Conference, 1999Abstract The Siri field is located in 60 metres water depth in the Danish sector of the North Sea. It was developed by a purpose built three legged jack-up standing on the top of a steel storage tank. The tank was installed in May 1998 and the jack-up was installed six months later.

Wave-in-Deck Load Analysis for a Jack-Up Platform
Journal of Offshore Mechanics and Arctic Engineering, 2011This paper describes the prediction of environmental loads on a typical three-leg jack-up platform under freak wave conditions. Considered were cases where the air gap is small and the hull is subject to impact-related wave-in-deck loads. The technique to predict wave loads was based on the use of a validated CFD code that solves the Reynolds-averaged ...

Wave-Deck-Load Analysis for a Jack-Up Platform
Volume 1: Offshore Technology, 2009The paper analyzes freak wave-in-deck load effects on a typical three-leg jack-up platform stationed in the North Sea. Considered were cases where the air gap is small and the hull is subject to impact-related wave-in-deck loads. Wave load predictions were based on the use of a validated CFD code that solves the Reynolds-averaged Navier-Stokes ...
