Abstract

A positioning member () for a tubular () is formed using a prefabricated fiber-reinforced resin shell () positioned upon a surface of the tubular and bonded to provide a protrusion upon the surface of the tubular. In a disclosed method a fiber-reinforced resin shell () is secured to an external surface of a tubular () thereby enclosing a cavity between the shell () and the surface of the tubular (); a bonding agent is introduced through inlet ports () in a surface of the fiber-reinforced resin shell () to fill a cavity between the shell () and the surface of the tubular (), and the bonding agent is cured.
