Abstract: Conical transitions have wide applications in wind turbine foundation as well as oil and gas jacket type of structures. The junctions where tubular and cone meet experience a sharp stress rise from shell edge effects. Like ...

Abstract: For the design of tubular conical transitions, the axial, bending, and hoop stresses at the junctions are required. Among the offshore design standards, API RP-2A, ISO 19902, and NORSOK N-004, various equations exist for ...

Abstract: Many offshore jackets have no braces between the top of jacket and the bottom of topsides deck. This can be either due to the installation requirement and/or an effort to reduce wave loads. This kind of jacket bay is a ...
