Electroslag remelting withdrawing technology for offshore jack-up platform rack steel manufacturing process

Journal of Iron and Steel Research International, 2016
Abstract Offshore jack-up platform rack steel must exhibit high strength and toughness as well as excellent welding properties. A high-quality large ingot is a prerequisite for obtaining a high-performance rough part. The electroslag remelting withdrawing (ESRW) technology using a T-shaped mold and bifilar mode was introduced to replace casting ...

A Floatable Offshore Process Plant Platform Designed To Jack-Up From Asubmerged Substructure

Offshore Technology Conference, 1979
ABSTRACT In order that small gas reserves or reserves of low quality gas in the North Sea could be exploited, a platform has been developed that can be moved from location to location even when completely fitted-out with equipment.

Hydrodynamic Loads, Soil and Structure Interaction in Conductor Design for Offshore Platforms and Jack-Up Rigs

IADC/SPE Drilling Conference and Exhibition, 2012
Abstract The design of a conductor casing is significantly different than that of the other tubulars in a well. Conductors are drag-dominated structures that enable conducting drilling operations from offshore fixed platforms or jack-up rigs through the seawater column.

System failure probability of offshore jack-up platforms in the combination of fatigue and fracture

Engineering Failure Analysis, 2011
Abstract 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.

K-Type, Inverse K-Type and X-Type Legs Stability Analysis of Jack-Up Offshore Platform

Applied Mechanics and Materials, 2013
The force situation of truss legs has an important impact on the jack-up offshore platform. The finite element analysis on three types truss leg was made, and the stability of the three types truss leg under preload, operating and storm survival condition was discussed.
