Nonlinear dynamic behaviour of jack-up platforms

Marine Structures, 1996
Abstract Jack-up platforms may, under extreme wave loading conditions, exhibit significant nonlinear behaviour. This must be accounted for in the design of such platforms, in order to ensure satisfactory structural safety. In this paper an overview of the different sources of nonlinear platform behaviour is presented. Furthermore, it is outlined how

Extreme-response analysis of jack-up platforms

Marine Structures, 1989
Abstract The extreme wave and current response of a typical North Sea jack-up drilling platform has been calculated using nonlinear, stochastic, time-domain analysis techniques. A statistical treatment of the response-time histories has been performed.

A Parametric Structure Optimization Method for the Jack-Up Platform

Volume 2: Structures, Safety and Reliability, 2012
In this paper, A parametric structure optimization method, which is called Parametric Structure Shape Optimization Method (PSSOM), is proposed in order to optimize the structure shape of the jack-up platform. According to the characteristic of the jack-up, an approach to create the Parametric Structure Model (PSM) is proposed.

SOME STRUCTURAL CONSIDERATIONS IN THE OPERATION OF JACK-UP PLATFORMS

Proceedings of Southeast Asia Show, 1984
Abstract Self-elevating mobile drilling or accommodation platforms, generally referred to as "jack-ups" have been on the offshore scene in some form or other for many years. In recent years the range and capability of such structures has extended to enable them to operate in water depths of greater than 400 feet, and in ...

Three-Dimensional Pushover Analysis of a Jack-Up Platform

Volume 2: Structures, Safety and Reliability, 2012
Jack-ups, as the name indicates, are self-elevating units consisting of a floatable hull and, usually, three truss work or circular legs. As a mobile structure, jack-ups are mainly utilized for oil and gas exploration and maintenance purposes in shallow to medium water (up to 120 meters), though they have recently seen application in the construction ...

Fixed and jack-up platforms: Basis for reliability assessment

Marine Structures, 1997
Abstract The introduction of the fixed jacket Load and Resistance Factor Design code (API RP 2A-LRFD), and the Jack-up Site Assessment Recommended Practice (SNAME T&R Bulletin 5-5A), raises debates regarding differences in the reliability levels associated with the use of the two documents.

Retractable Pile: A New Solution for Jack-up Platform

Offshore Technology Conference, 2007
Abstract Within its jack-up development framework, Technip has developed a new foundation concept that widens the range of soil conditions where a jack-up production facility can be used without compromising its self-installation capability (i.e using only minimal support).
