.... The abstract must contain conspicuous acknowledgment of where and by whom the paper was presented. Abstract Tubular joints are integral components of offshore structures and as such, many codes and standards address their design. The fatigue damage process of tubular joints in offshore structures is inherently...

... Abstract A Joint industry project (JIP) commenced in 1993'" to develop a design manual for tubular joints which are strengthened or repaired through chord grout-filling. This project has been funded by five oil companies and two regulatory bodies. The project has comprised the conduct of over...

... ABSTRACT A fatigue fracture mechanics model is described which can be used to predict the remaining fatigue life of cracked tubular joints. To perform this analysis knowledge of the maximum stress at the intersection (termed the hot-spot stress), together with the distribution of stress...

... ABSTRACT The effects of stiffeners on the stress state of a tubular joint are investigated. Several aspects of stiffener modelling for finite element analyses are first discussed, using a two-plane T-joint. This joint was modelled with and without internal ring and longitudinal stiffeners...

Due regard is given to the fitness-for-purpose of the tubular joint in the context of the structure as a whole. Offshore repairs are costly and should be avoided wherever possible. The high costs...

... ABSTRACT From an ultimate strength standpoint, research to date on tubular joints has concentrated on testing work. However, the high costs associated with testing has directed recent efforts towards non-linear analysis techniques to generate data and information. This paper gives a background...
