This work considers a predictive numerical modelling approach for fracture-propagation control in CO 2 -transport pipelines, an area where current engineering tools do not work. Fluid–structure interaction model simulations are compared with three

In this study, we present results from a numerical model of a full-scale fracture propagation test where the pipe sections are filled with impure, dense liquid-phase carbon dioxide. All the pipe sections had a 24″ outer diameter and a diameter/thic

In this paper a new method of connecting pipe to flange without welding is presented. This method is a cold forming process that is based on plastic expansion/deformation of the pipe into a modified standard flange by use of a cold forming tool. The

Fracture propagation control (FPC) is important in design and operation of pipelines for gas transport. Predicting and understanding the velocity of a running ductile fracture remains as one of the toughest challenges in the fracture research communi

One challenge in CCS is related to the prevention of running-ductile fracture in CO 2 -carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be appropriate for CO 2 transpo

We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an outer diameter of 267 mm and

Existing engineering methods to ensure fracture propagation control in natural-gas transmission pipelines have been shown to be non-applicable when dense-phase CO 2 is transported. To overcome this, a coupled fluid–structure interaction model has b
